Retirement Savings Calculator

No. It is an estimate that assumes a steady return, unchanging inflation, and contributions that arrive exactly as planned. Real markets rise and fall, so your actual balance will differ, sometimes a lot. The default plan projects about 1,260,443 at age 65, but that rests on earning a flat 6% every year for 35 years straight. Read it as a planning sketch that shows how your inputs interact, not a promise, and note it is not financial, investment, or tax advice.

From your current age to your retirement age the balance moves forward month by month. Within each month, three things happen in turn: interest is credited using a monthly-equivalent rate, i_m = (1+R)^(1/12) - 1, taken from your annual return; any annual fee is charged; and your monthly contribution is added. That contribution can rise each year. Across 420 months the default 50,000 start plus 500-a-month saving grows to roughly 1,260,443 - about 299,967 of that your own contributions and 910,476 investment growth.

You choose how the target nest egg is defined. On the income basis, you name the yearly income you want in today's money; the tool grows it for inflation to your retirement date, then computes the lump sum needed to pay that rising income for your chosen number of retirement years while the balance earns the net return and empties to zero. On the fixed basis, you simply type a nest-egg figure. The default income basis needs about 1,633,079, roughly 688,132 in today's money.

The funding ratio divides your projected nest egg by the target nest egg. The readiness score is that same ratio put on a 0-to-100 scale and capped at 100, so meeting or beating the target reads as a full 100. In the default plan the projection covers about 77% of the target, giving a score of 77 and the "needs attention" band. Anything under 100 flags a shortfall - here about 372,636 - while 100 means the projection reaches or clears the goal.

Alongside the projection, the tool solves backward for the monthly contribution that would land your balance exactly on the target by retirement age, holding your other inputs fixed. It searches for the figure that closes the gap. In the default plan the answer lands near 713 a month, roughly 213 more than the 500 being saved now. If your current saving already reaches the target, no increase is needed; if even very large contributions can't get there in the years left, the tool says so.

Inflation never touches the nominal nest egg. The future statement balance is the same whether you assume 0% or 5% inflation, because your return and contributions build it regardless. What inflation does is two-sided: it shrinks the real, today's-money worth of that balance, so 1,260,443 is worth about 531,114 now, and it lifts the income target, since 40,000 of spending decades from now costs far more in future money. Higher inflation therefore widens the gap without moving the headline figure.

Two optional deductions apply while the nest egg builds. An annual fee or expense ratio is charged on the balance each year, trimming what compounds. An annual tax is taken on that year's investment gains, so only after-tax growth carries forward. Both default to zero. For tax-deferred accounts such as a 401(k) or traditional IRA, leaving the tax at zero is usually right, since gains aren't taxed until you withdraw. Set a rate only for an account taxed yearly. These are rough flat-rate estimates, not tax advice.

Years in retirement is how long your savings must last after you stop working - 25 in the default plan - and it does two jobs. First, it sizes the income-basis target: more years means a larger lump sum to fund. Second, it drives the drawdown, where the tool pulls your inflation-growing income out of the projected nest egg year by year and checks whether the money survives the full stretch or runs dry sooner, and what steady income the balance could genuinely support.

When the income you want outpaces what the nest egg can carry, the drawdown empties it before the retirement span ends. The tool reports the age the money runs dry and how many years short that leaves you. In the default plan the first-year withdrawal is about 94,928 - that's 40,000 grown by inflation over 35 years - and drawing it anyway drains the pot in roughly 17 of the 25 years, empty around age 83. The same balance could instead sustain about 30,873 a year in today's money.

Contribution escalation raises your monthly saving by a fixed percentage once a year, mirroring how people tend to save more as their pay grows. The default steps the 500 up by 2% each year, so it becomes 510 in year two, about 520 in year three, and keeps climbing from there. Because later contributions are bigger and still have years to compound, escalation lifts the final nest egg noticeably versus a flat amount. Set it to zero to keep every contribution identical for the whole horizon.

Yes, a little. The timing setting fixes when each contribution arrives relative to that month's interest. A start-of-month contribution is present when interest is credited, so it earns that same month; an end-of-month one arrives after interest is figured and waits a month to begin growing. Over 420 months the start option leaves a slightly larger nest egg, because every contribution picks up one extra month of compounding. The effect is small next to your return and saving rate, yet real, and it grows with the horizon.

Use a realistic long-run figure for how your money is genuinely invested, not a hoped-for peak year. The 6% default is meant as a middle-of-the-road placeholder; the right number for you depends on your asset mix and risk tolerance, and a cautious, bond-heavy plan warrants a lower one. Because the tool applies a single steady rate for decades, it is wise to re-run the plan with a gentler return to see a more conservative nest egg before leaning on any one projection.

This calculator follows one steady path: a fixed return, fixed inflation, and a single projected nest egg. A fuller retirement tool might replay hundreds of random market scenarios - a Monte Carlo simulation - to report a probability of success, model the risk of poor early returns, or fold in Social Security, pensions, and employer matches. None of that lives here. The trade-off is clarity: you see exactly how each input moves the result, at the cost of not capturing how much market luck and timing can sway a real outcome.

No. It is an educational planning aid for testing scenarios and getting a feel for scale, offered as general guidance rather than tax, investment, or retirement advice. It leaves out market volatility, Social Security, pensions, employer contributions, account contribution limits, and real tax rules, and it assumes your inputs hold steady for decades. Before making decisions that carry real consequences, confirm the specifics with a qualified financial or tax professional who can weigh your whole situation, including the moving parts this model deliberately keeps simple.
