How this date was worked out
- Your $100,000 goal grows with 2.5% inflation, so by the finish it costs about $141,297.
- Starting with $10,000 and adding $500 a month at 5.12% APY, the balance builds month by month.
- It first crosses the goal after about 14 yr — 168 months of saving.
- A rising goal costs time: without inflation you would arrive at month 127, so inflation adds 41 months.
- Along the way you earn $47,407 in interest on $84,000 of deposits.

How to use
- 01
Lay out the plan you are timing: the goal in today's money ($100,000), what you have already banked ($10,000), and the deposit you add each month ($500). These three lines set the starting height of the balance and how fast it climbs.
- 02
Set the growth and inflation assumptions that shape both curves: a 5% APR compounded monthly (shown back to you as a 5.1162% APY), 2.5% goal inflation, and whether deposits land at month end. Leave the yearly deposit increase, monthly fee, and interest tax at zero for the base run, or switch them on to watch the finish line shift.
- 03
Read the headline the tool returns: with these inputs the balance overtakes the rising goal at month 168 — a goal date exactly 14 years out. At that month the inflated target sits at $141,297.38 and the balance is $141,407.41, clearing the line by about $110.03 on $84,000 of deposits and $47,407.41 of interest.
- 04
Check the inflation-delay reading, the figure unique to this tool: rerun the identical plan against a fixed $100,000 goal and it arrives at month 127 (10 years 7 months). The gap, 41 months, is exactly what 2.5% inflation adds by walking the target away from you as you chase it.
- 05
Flip to a reverse mode when you have a date in mind instead of a lever. Pin a 10-year deadline (120 months, where the inflated goal is $128,008.45) and the tool solves the one input that lands you there: $718.29 a month, or a 9.83% APR (10.28% APY), or a $30,581.07 head start today.
- 06
Save the run and stack it against the alternatives — the 14-year base plan beside the $718.29 forced-deadline plan — so the trade between a bigger deposit and a later date sits side by side rather than in your head.
Formula
The tool marches forward in monthly steps and watches for the first month the balance line crosses the goal line. Each month the running balance earns growth and takes in that month's deposit: the nominal APR is folded together with its compounding frequency into a single monthly growth factor (an APY entered directly is converted the same way, so both routes drive one equivalent monthly rate), a flat monthly fee is subtracted, and any yearly interest tax trims the credited earnings. If contribution escalation is on, the deposit steps up by the set percentage on each anniversary, so later months push harder. Meanwhile the goal itself is not standing still — it rises as goal(t) = goalToday x (1 + inflation)^(t/12), lifting a little every month — and the crossing month is simply the first month the balance reaches that moving target. Run the same plan against a flat, un-inflated goal and it crosses earlier; the inflation delay is exactly the difference between the rising-goal crossing month and the fixed-goal crossing month.
Example
Start with $10,000 saved, add $500 at each month's close, and let the balance compound at 5% APR monthly (a 5.1162% APY) while a $100,000 goal drifts upward at 2.5% a year. Month after month the deposits and interest stack up, but so does the target, and the two lines finally meet at month 168 — a goal date 14 years out to the month. By then inflation has carried the goal from $100,000 to $141,297.38, and the balance stands at $141,407.41, clearing the finish by roughly $110.03; of that total, $10,000 was your opening balance, $84,000 came from the 168 deposits, and $47,407.41 from interest — a growth multiple of about 1.50x on the $94,000 you put in. The moving target is the whole story: freeze the goal at a flat $100,000 and the identical plan arrives at month 127, or 10 years 7 months, so the rising goal costs 41 extra months — about three and a half years of inflation delay. If instead a 10-year deadline is fixed, where the inflated goal is $128,008.45, the tool answers in reverse and tells you the deposit has to climb to $718.29 a month to land right on time.
Definitions
- Goal date
- The calendar month when your balance first meets or passes the goal. It is the month count translated onto a real timeline. In the default plan that is month 168, exactly 14 years out.
- Months to goal
- The raw count of monthly steps the plan takes to reach the target, before it is rendered as a date. The engine tallies these steps and stops the first month the balance clears the goal. The default plan needs 168 of these steps.
- Moving (inflated) goal
- A target that grows with inflation instead of staying fixed, computed as goalToday x (1 + inflation)^(t/12). Because it rises every month, your balance has to chase a line that keeps climbing. At month 168 the default $100,000 goal has swelled to $141,297.38.
- Inflation delay
- The extra months a rising goal costs you versus an unchanging one. With inflation off, the default plan lands at month 127; with 2.5% inflation it slips to month 168, so the delay is 41 months - about 3 years 5 months.
- Monthly deposit
- The set sum you pay in each month, applied at month end in the default setting. The default $500 deposit totals $84,000 over the 168 months to goal. Raising it is the most direct way to pull the date closer.
- Contribution escalation
- An optional yearly bump to the monthly deposit, applied as a set percentage once every twelve months. Because later deposits are larger, the balance climbs faster and the goal date moves earlier. It models a plan that grows with your income.
- Compounding frequency
- How often the entered return is credited - monthly, quarterly, and so on. The stated APR is divided across those periods, so more frequent compounding earns slightly more and shaves time off the date. The default compounds the 5% APR monthly.
- APR vs APY
- APR is the nominal annual rate before compounding; APY is the effective yield after it. A 5% APR compounded monthly works out to a 5.1162% APY. The tool accepts either - it treats an APR as nominal and passes an APY through unchanged.
- Deposit timing
- Whether each contribution lands at the end or the start of the month. End-of-month deposits, the default here, earn no interest in the month they arrive, so start-of-month timing reaches the goal marginally sooner.
- Target deadline (reverse mode)
- A fixed date you commit to, against which the tool solves for the lever needed to arrive on time. Pinning the default plan to a 10-year deadline sets the goal at $128,008.45 under 2.5% inflation. The engine then finds the deposit, return, or head start that hits month 120.
- Required deposit / return / head start
- The three reverse answers for a chosen deadline. To arrive at 10 years the default plan needs $718.29/month, or a 9.83% APR (10.28% APY), or a $30,581.07 starting balance - any one of them alone. Each solves while the other inputs stay put.
- Growth multiple
- Ending balance divided by every dollar put in — your $10,000 starting balance plus $84,000 of deposits, $94,000 in all. The default plan grows that $94,000 into $141,407.41, a multiple of about 1.50x. The $47,407.41 on top of the money paid in is the interest earned.
Good to know
Why "when" is the question savers actually have
Ask anyone building toward a big number — a house down payment, a wedding fund, a cushion of $100,000 — and the worry underneath is almost never the arithmetic of the target itself. It is the calendar. People want to know the month they can stop waiting: the point where the account finally clears the line and the plan is done. That single date decides whether a goal fits a life or fights it. This calculator is built around that one question. Given what you have saved, what you add each month, and how your money grows, it reports the month your balance first reaches the goal and translates that count into a real finish date you can circle. In the default plan — $100,000 in today's money, $10,000 already banked, $500 a month, 5% APR compounded monthly, and 2.5% goal inflation — the answer lands at month 168: exactly 14 years and 0 months out. That framing matters because a date is actionable in a way a dollar figure is not. A finish 14 years away invites a different decision than one 10 years away: you can weigh whether to lift the monthly deposit, chase a higher return, or start with a larger head start to move the date closer. Every lever in the tool ultimately reports back in the same currency — time. Rather than leaving you to guess how a change ripples through the years, the engine re-crosses the finish line and tells you the new month. The goal amount sets where the line sits; this tool tells you when you cross it, and how each choice you make slides that day nearer or pushes it away.
How the month-by-month engine finds your goal date
The tool does not lean on a single closed-form formula, because a realistic plan has too many moving parts for one — deposits arriving on a schedule, growth compounding, a target that may itself be drifting upward. Instead it walks the account forward in single-month steps and watches for the first month the balance reaches or passes the goal for that month. That crossing month is your answer, and the UI turns the count into a calendar date. Before the walk begins, the return is put on a common footing. The entered figure is treated as a nominal APR compounded at the frequency you pick, so the default 5% APR compounded monthly works out to a 5.1162% APY — the true annual growth once compounding is counted. Internally the engine converts that to a per-month growth rate, applies it to the running balance, and then adds your deposit (at month end in the default), repeating the cycle month after month. With the default plan the crossing arrives at month 168. By that point you have paid in $84,000 across 168 deposits of $500, and the balance stands at $141,407.41 — of which $47,407.41 is interest earned on top of the $94,000 you put in (your $10,000 head start plus the deposits), a growth multiple of about 1.50x. The balance clears the goal line for that month, $141,297.38, by roughly $110.03, which is exactly what a month-by-month crossing looks like: you do not stop precisely on the number, you stop the first month you are past it. Because the engine simulates rather than approximates, optional drags like a fixed monthly fee or an annual tax on earnings slot naturally into each step and simply push the crossing to a later month.
Inflation as a moving finish line — the inflation delay
Most savings math treats the goal as a fixed post you are running toward. Real goals do not hold still. If $100,000 buys what you need today, the same basket costs more every year that prices rise, so the amount you must actually accumulate keeps climbing while you save. This tool models that directly: the goal grows at the inflation rate, goal(t) = goalToday × (1 + inflation)^(t/12), which means the finish line is retreating even as your balance advances toward it. The effect is larger than most savers expect. In the default plan, 2.5% inflation lifts the $100,000 target to $141,297.38 by the time you reach it — you are no longer chasing six figures but well past $141,000. That is why the crossing lands at month 168 rather than sooner: your deposits and growth have to catch a line that has moved. The signature figure here is the inflation delay — the extra months the rising goal costs you versus a fixed one. Switch inflation off and hold everything else the same, and the identical plan reaches a flat $100,000 goal at month 127, or 10 years and 7 months. Turn the moving target back on and the finish slides to month 168. The gap between them, 41 months — about 3 years and 5 months — is the price inflation quietly adds to your timeline. Seeing that delay as a concrete stretch of time, rather than an abstract percentage, reframes the decision: it shows why a plan that looks comfortably on schedule against today's number can still run years long once the target is allowed to drift. It also makes the case for the levers that pull the date back in.
Contribution escalation: raising deposits over time to pull the date in
A deposit that never changes is the easy default, but it is rarely how earnings actually move. Raises, promotions, and simple habit tend to lift what a saver can set aside each year — and the tool lets you build that in with contribution escalation: the monthly deposit rises by a set percentage once a year. Each year the amount you pay in steps up, and because those larger deposits arrive earlier in the remaining timeline, they compound longer and carry more weight than a late lump ever could. The reason this pulls the finish date closer is the same reason inflation pushes it away, working in your favor. Inflation lifts the line you are chasing; escalation lifts the pace at which you close on it. Where the default plan holds the deposit flat at $500 a month and crosses the goal at month 168, letting that deposit climb each year feeds the account a steadily rising stream, so the balance reaches the moving target in fewer months. The steeper the yearly step, the earlier the crossing. Escalation is also a natural counter to the inflation delay. If prices are lifting your goal by 2.5% a year, holding your deposit fixed means you are effectively saving less in real terms each year even as the target grows — the two forces pull the date in opposite directions and inflation wins. Nudging your contribution up on a similar cadence keeps your saving power roughly in step with the rising line instead of falling behind it. Because the engine re-runs the full month-by-month walk with each year's larger deposit already in place, the finish date it reports reflects exactly how much time a modest annual raise buys back — turning a vague intention to "save more later" into a specific number of months shaved off the calendar.
The reverse modes: pinning a deadline and solving the deposit, return, or head start
Forward mode answers when you will arrive. Just as often the date is the fixed part — a deadline that will not move — and the real question is what it takes to hit it. The reverse modes flip the calculation: you pin a target date and the engine solves for the single lever that makes the plan land exactly on it, whether that is the monthly deposit, the return, or the starting balance. Take the default plan but demand the goal in 10 years — 120 months instead of 168. Under 2.5% inflation the target at that earlier date is $128,008.45, since a nearer finish means the goal has had less time to grow. Each reverse mode holds the rest of the plan steady and finds the one input that reaches that number by month 120. Solve for the deposit and the answer is $718.29 a month, up from $500 — the extra $218.29 each month is the cost of arriving four years sooner. Solve for the return instead and the plan needs roughly 9.83% APR, which surfaces as a 10.28% APY: a demanding growth rate that shows how much heavier a lift returns must do when time is cut short. Or solve for the head start — the starting balance that gets you there — and the plan requires $30,581.07 in the account today, well above the default $10,000, because a larger base compounds across the whole shortened window. Seeing all three side by side turns an abstract deadline into a clear menu of trade-offs. You can save more each month, seek a higher return, or open with more capital — and the engine prices each path in the exact terms the deadline demands, so you choose the lever that actually fits your situation.
APR, APY and compounding frequency
The return field accepts two readings of the same idea, and which one you pick changes how the math runs — and therefore where the finish line lands. Enter a nominal APR and the calculator compounds it at the frequency you choose, splitting the yearly rate across each period. Enter an APY and it is passed straight through as the true annual growth already baked in. The default plan uses 5% APR compounded monthly, which works out to a 5.1162% APY once the twelve monthly steps stack on themselves. That gap between 5% and 5.1162% is compounding at work: the same headline rate, applied more often, does slightly more. Frequency is the lever most people overlook. Monthly compounding credits growth a dozen times a year; daily compounding does so 365 times; annual compounding waits until the year is out. More frequent compounding lifts the effective yield a touch, which nudges the goal date a little earlier — though the effect is modest next to your deposit size. What matters most is entering the number the way your account quotes it. Banks usually advertise APY, brokerages and loans usually quote APR, and mixing them up shifts your projected date without you noticing. In the default scenario the 5% APR carries the balance to the inflation-adjusted goal at month 168 — exactly 14 years. If you instead typed 5% as an APY, the underlying periodic rate would be a hair lower and the date would drift slightly later, because you would be asking less of the account each month. When two calculators disagree on a date, the compounding convention is the first thing to check.
How fees and interest tax push the date later
Two quiet drags sit between your deposits and the date on the calendar: a fixed monthly account fee and an annual tax on the interest you earn. Neither is in the default plan — the headline 14-year, month-168 result assumes no fee and no tax — but switching either on moves the finish line in the wrong direction, and it helps to see why. A flat monthly fee is subtracted from the balance every month before growth is figured. It behaves like a negative deposit: part of your $500 is quietly spent keeping the account open rather than building toward the goal. Because the fee is a fixed dollar amount rather than a percentage, it bites hardest early, when the balance is small and has the fewest years left to recover the loss through compounding. Even a few dollars a month, repeated across a fourteen-year horizon, pushes the reach date out by more months than the raw total suggests. Interest tax works on the growth rather than the principal. Each year a share of the interest earned is skimmed off, so the balance compounds on a smaller base going forward. In the default plan the account earns $47,407.41 of interest across the run; a yearly tax claims a slice of that engine before it can compound, so the same $84,000 of deposits has to carry more of the load and the goal arrives later. The higher your assumed return, the more tax there is to lose, which is why a fee and a tax together can erase much of the advantage a strong rate was supposed to buy. Enter both honestly — an optimistic, cost-free projection produces a date you cannot actually keep.
Reading the projection table and progress chart
The projection table is the month-by-month story behind the single date at the top. Each row shows the balance climbing as deposits and interest accumulate, alongside the goal for that month — and in the default plan the goal is not a flat line. Because inflation lifts the target by 2.5% a year, the goal column rises from $100,000 in today's money toward $141,297.38 by the month you actually arrive. Watching both columns climb makes the chase visible: you are aiming at something that keeps moving. The reach marker is the moment the two finally cross. In the default scenario that is month 168, where the balance reaches $141,407.41 against a goal of $141,297.38 — clearing the line by about $110.03. The overshoot is normal: deposits land in whole monthly steps, so the balance vaults over the target during the month it qualifies rather than settling exactly on it. The marker sits at that first crossing, and the calendar date shown up top is simply month 168 counted forward from today. The progress chart draws the same thing as two curves — your balance and the rising goal — with the reach point flagged where they meet. Reading them together tells you more than the headline date alone. A balance line that runs nearly parallel to the goal for years before closing the gap signals a plan that is only just keeping pace; a line that pulls away steeply shows real headroom. Scan the early rows too, since that is where a fee or a slow start does the most damage to your timeline. The table is where an abstract deadline becomes a schedule you can sanity-check.
What shaves the most months off your timeline
Four levers move the goal date, and they are far from equally strong. The honest way to rank them is to hold a deadline fixed and see what each demands — the reverse modes do exactly that against a 10-year (120-month) target, where inflation has lifted the goal to $128,008.45. Saving more is the most direct. To arrive at the 10-year mark instead of month 168, the monthly deposit rises from $500 to $718.29 — more cash every month, but with no assumptions required. It works because you control it outright; the money goes in regardless of what markets do. Earning more is powerful but demanding. Hitting the same deadline purely on return means lifting the rate from 5% APR all the way to roughly 9.83% APR — a 10.28% APY. That is a large, uncertain jump that carries real risk, and unlike a bigger deposit it is not something you can simply decide to do. A head start collapses the timeline fastest per dollar, if you have the cash. Raising the opening balance from $10,000 to $30,581.07 reaches the goal by year ten, because that money compounds for the full run rather than trickling in. Escalation is the patient lever: letting the deposit rise a set percentage each year pulls the date in gradually as your contributions grow with your income. And lowering inflation, though rarely in your control, matters enormously — switching the 2.5% goal drift off entirely moves the default arrival from month 168 to month 127, a saving of 41 months. Rank your options by what you can actually change: for most people, a modest bump to the monthly deposit beats chasing a rate that may not materialize.
Limits and good habits
This calculator projects a clean path, and real life is bumpier — so read the date as a well-reasoned estimate, not a promise. A few assumptions are worth keeping in mind. Deposits are treated as fixed nominal amounts unless you turn on escalation. A $500 deposit in year fourteen is the same $500 you enter today, even though inflation will have eroded what it buys — which is part of why the rising goal takes 168 months to catch rather than the 127 a fixed target would. If your real-world contributions grow with your salary, the escalation setting captures that; if they do not, expect the later years to feel harder than the early ones. The projection also stops at a 100-year cap. If a plan cannot reach its goal within that window — a deposit too small to outrun inflation, or a return that never lets the balance close the gap — the calculator reports that rather than running forever. Treat an unreachable result as a signal to change a lever, not as a rounding quirk. Above all, the calendar date is counted forward from today, so it drifts the moment your inputs change. Revisit the plan when your income shifts, when a raise frees up money you can route into deposits, or when rates or inflation move meaningfully. The default run — 14 years to a goal that inflation has grown to $141,297.38, built from a $10,000 head start, $84,000 of deposits and $47,407.41 of interest — is a snapshot of one set of assumptions. Rerun it a couple of times a year, adjust the deposit before you adjust your hopes for the rate, and the date on the calendar will stay honest.
Frequently asked questions
How is my goal date calculated?
The tool walks your balance forward month by month, adding your deposit and crediting return at the chosen compounding frequency. It stops the first month the balance meets or passes the goal and reports that month as a calendar date. In the default plan that happens at month 168, or exactly 14 years.
Why does inflation push my goal date back?
When goal inflation is on, the target itself grows at goalToday x (1 + inflation)^(t/12), so the finish line moves away from you each month. Your balance has to outrun a rising number rather than a fixed one. That is why the default plan slips from month 127 to month 168 once 2.5% inflation is applied.
What is the inflation delay?
It is the number of extra months the moving goal costs compared with a fixed goal on the same plan. Switch inflation off in the default scenario and you arrive at month 127; leave 2.5% on and it becomes month 168. The 41-month gap - roughly 3 years 5 months - is the inflation delay.
How do the reverse modes pick a deadline?
You set the deadline yourself, and the tool freezes the goal at its inflated value on that date. For the default plan a 10-year deadline fixes the goal at $128,008.45. The engine then solves for whichever single lever - deposit, return, or starting balance - lands you there on month 120.
Does a yearly deposit increase help much?
Yes, because escalation makes your later deposits larger, and larger deposits compound sooner, which pulls the date earlier. A plan that raises the monthly amount once a year reaches the goal before a flat plan of the same starting size. How much it helps depends on the escalation percentage you set.
Why is required return shown as an APY?
The reverse solver works in the effective yield so the figure reflects what you would actually earn after compounding. For the default plan aimed at 10 years, the required return is about 9.83% APR, which is 10.28% APY. Showing the APY lets you compare it directly against advertised account yields.
What if I never reach the goal?
If your deposits and return cannot outpace the rising goal, the balance never crosses the line and no date exists. This tends to happen when the return trails inflation and deposits are small. The fix is to raise the deposit, seek a higher return, or start with more saved - the reverse modes tell you exactly how much.
Do fees and taxes change the date?
They push it later. A flat monthly fee is skimmed off the balance each month, and yearly interest tax trims what compounding adds back, so both slow the climb toward the goal. The default plan carries neither, which is why it reaches month 168 cleanly.
APR or APY - which should I enter?
Enter an APR if you have a nominal rate that gets compounded, and the tool will apply your compounding frequency to it. Enter an APY if your account already quotes an effective annual yield, and it is used as-is. The default 5% APR compounded monthly is equivalent to a 5.1162% APY.
Is the goal in today's or future money?
You enter it in today's money, and the tool inflates it to future dollars as the months pass. The default $100,000 goal is stated in today's prices, but the balance actually has to reach $141,297.38 by month 168 to count as met. That keeps the finish line honest as prices climb.
Can I reach it faster by saving more or earning more?
Both work, and the reverse modes quantify each. On the default plan aimed at 10 years, lifting the deposit to $718.29/month gets you there, and so does raising the return to a 10.28% APY - either one alone. A bigger head start of $30,581.07 does the same job without changing the monthly plan.
How accurate is the calendar date?
The month count is exact for the assumptions you enter, and it is converted to a date by counting whole months from today. The precision of the calendar day depends on your inputs holding steady - real deposits, rates, and inflation drift over years. Treat the date as a well-grounded projection rather than a guarantee.
What compounding frequency should I choose?
Match it to how your account actually credits interest - monthly for most savings accounts, quarterly for some deposits. More frequent compounding earns slightly more and nudges the date a little earlier for the same APR. The default compounds monthly, turning 5% APR into a 5.1162% APY.
Can I compare two plans?
Yes. The clearest comparison built into the tool is your plan against the same plan with inflation switched off, which exposes the 41-month inflation delay in the default scenario. You can also change one lever - deposit, return, or head start - and watch the goal date move to see which change buys you the most time.
