How to use
- 01
Enter everything you own in the total-assets field and everything you owe in the total-debts field. Net worth is the difference, and it is what every rung on the ladder is measured against.
- 02
Enter what you save and invest each month, and separately the principal your loan payments retire each year. Both build net worth; interest does not.
- 03
Set the expected return on the invested part of the balance sheet.
- 04
Put a figure in the extra-monthly field — anything you might realistically add. The last column of the table fills in with what that amount buys at every rung.
- 05
Read the headline date for the next rung, then the table for the whole ladder from here. To date a target of your own instead, put it in the custom-target field in the advanced panel.
Formula
Net worth = total assets − total debts. Your monthly pace = monthly saving + annual loan principal ÷ 12. The balance is then compounded monthly at the annual return divided by twelve, with the pace added each month, until it reaches the milestone: balance = balance × (1 + return ÷ 12) + pace, counted month by month. The second column repeats the whole run with the extra monthly amount added to the pace, and the difference between the two counts is what the extra buys. A run that has not reached the target after 1,200 months is reported as beyond 100 years rather than as a number.
Example
$611,000 of assets against $302,000 of debts is $309,000 of net worth, so the next rung is $500,000 and there is $191,000 to go. Saving $1,500 a month and retiring $9,600 of principal a year is a pace of $2,300 a month; at a 6.5% return that reaches $500,000 in 3 years and 7 months. Adding $500 a month brings it to 3 years and 3 months — four months sooner. Further up the ladder the same $500 buys more: $1,000,000 arrives in 10 years and 3 months at the base pace and 9 years and 5 months with the extra, ten months sooner. And the shape of the climb shows in the comparison the page runs beside it: the first $500,000 from nothing takes 12 years and 1 month, the second takes 6 years and 9 months.
Definitions
- Milestone ladder
- The standard round numbers people actually aim at, from $10,000 to $10,000,000. The page picks the smallest one above your current net worth.
- Monthly pace
- What you add to net worth each month — your saving plus one twelfth of the loan principal you retire in a year.
- Compounding
- Growth earned on growth. It is why the same dollar distance takes less time the higher up the ladder it is climbed.
- Face value
- What an asset is nominally worth, before any tax, penalty or selling cost. Milestones are counted at face value, which is why crossing one is not the same as being able to spend it.
Good to know
Why round numbers are worth aiming at
There is nothing special about a hundred thousand dollars. It is not a threshold in the tax code, it does not unlock an investment, and no financial rule of thumb turns on it. What it is, reliably, is a number people can hold in their heads — and a target you can picture is one you actually save toward, which is why round-number milestones outperform percentage-of-income targets for most households in practice if not in theory. The ladder this page walks is the one people actually use: ten, twenty-five, fifty and a hundred thousand while the balance sheet is small and every dollar is one you put there; then two-fifty, five hundred, a million as compounding starts carrying part of the load; then the larger rungs, which arrive at intervals that shorten in relative terms even as they lengthen in dollars. The value of dating them is not the date. It is that a distant, abstract ambition becomes a specific number of years, and a specific number of years responds visibly to a change in the monthly figure.
The same distance, climbed from a different height
"Each milestone comes faster than the last" is repeated so often that it is worth being precise about what is actually true, because the loose version is false. The rungs on any milestone ladder are not evenly spaced — going from $500,000 to $1,000,000 is a jump of half a million where going from $250,000 to $500,000 is a quarter of one — so comparing the time between adjacent rungs compares two different distances and proves nothing. The claim that does hold is about EQUAL distances. At this page's defaults, climbing $500,000 from nothing at a $2,300 monthly pace takes twelve years and one month. Climbing the same $500,000 again, starting from $500,000, takes six years and nine months. Nothing about the saving changed. What changed is that the balance is now throwing off enough return to cover part of the climb, and that share grows with every rung. The practical consequence is that the early years feel disproportionately slow and are not evidence that the plan is failing — they are evidence that you have not yet accumulated a base large enough to help.
What an extra hundred dollars is actually worth
The most useful column on this page is the last one, and it exists because the value of an increased contribution is almost impossible to intuit. An extra $500 a month at the page's defaults brings the $500,000 rung forward by four months — modest, and roughly what most people would guess. It brings the $1,000,000 rung forward by ten months, and the rungs beyond that by more than a year each. The pattern is consistent and it has one cause: money added at the front of a run has the entire horizon to compound, so the further away the target, the more the same increase is worth. The corollary is the part worth acting on. The same $500 started five years from now buys a fraction of what it buys started today, which means the honest way to price a raise, a cancelled subscription stack or a refinanced car payment is not as an annual total but as a date moved. A hundred dollars a month is $1,200 a year and it is also, over a long enough target, most of a year of your life.
The number you cross is not the number you can spend
Every milestone on this ladder is counted at face value, which is the standard and correct way to measure net worth and also the reason crossing one can feel strangely hollow. Half a million dollars of net worth is a genuine achievement and it can also be four hundred thousand of home equity, a 401(k) you cannot touch for twenty years without paying income tax and a 10% penalty, and a car. The household is worth exactly what the milestone says and could reach perhaps a tenth of it this month. This is not an argument against tracking milestones — the composition problem is separate from the accumulation one, and a growing net worth made of illiquid assets is still a growing net worth. It is an argument for tracking a second number alongside it. The households that get into trouble are not the ones with too much home equity; they are the ones who read a face-value figure as available money, carry no cash buffer behind it, and then meet a job loss or a roof with a credit card. Cross the milestone, then check what you could reach.
Frequently asked questions
Which milestone does it pick?
The smallest round number on the standard ladder above where you stand: $10k, $25k, $50k, $100k, $250k, $500k, $1M, $2.5M, $5M, $10M. At $309,000 of net worth the next rung is $500,000. If you are already past every rung the ladder extends a million at a time so there is still an answer, and the custom-target field overrides the whole thing if you have a number of your own.
Why does the same distance take less time later on?
Because the return does more of the work the higher the base is. At the page's defaults, climbing $500,000 from nothing at your pace takes 12 years and 1 month; climbing the same $500,000 again starting from $500,000 takes 6 years and 9 months. Nothing about your saving changed — the balance is now earning enough to carry part of the load. That is the honest version of "each milestone arrives faster": the rungs on the ladder are not evenly spaced, so comparing two adjacent rungs compares two different distances.
Is the first $100,000 really the hardest?
The arithmetic backs the folklore. At a 6.5% return, $100,000 throws off about $6,500 a year on its own, which at a $2,300 monthly pace is roughly three months of saving arriving for free. Below that level the balance moves essentially because you moved it; above it, the market starts contributing something you would notice on a statement. Nothing magical happens at the number itself — it is simply where compounding becomes visible at ordinary saving rates.
Why does an extra $500 a month move the date so much?
Because it lands at the front of the run, where every dollar has the entire horizon left to compound. At the defaults it brings the $500,000 rung forward by four months and the $1,000,000 rung forward by ten — the further out the milestone, the more the same increase buys. The same $500 started five years from now buys a fraction of that, which is the real argument for raising a contribution today rather than promising to raise it later.
Should paying off debt count toward a milestone?
Yes, and it is the half most milestone calculators drop. Net worth is assets minus liabilities, so a dollar off a loan balance moves it exactly as far as a dollar into an index fund — and it does it with certainty rather than with the market's permission. Only principal counts, which is why the field asks for principal and not the payment. Your loan statement splits every payment into interest and principal.
Does crossing a milestone mean I can spend it?
No, and this is the trap in every net-worth target. A milestone counts everything at face value, so half a million of net worth can be four hundred thousand of home equity and a 401(k) you cannot touch for twenty years without paying income tax and a 10% penalty. What you could actually reach is a different and usually much smaller number, and it has its own page.
How is this different from a savings goal calculator?
A savings goal date works from one pot with one deposit. This works from a whole balance sheet — assets, debts, saving and loan principal together — so it can tell a household with a mortgage and a 401(k) something a single-pot calculator cannot. It also runs the entire ladder rather than one target, and it prices a second pace beside the first.
