Ten years in, a $500-a-month habit is worth about $86,500. It does not feel like financial independence. It feels like a savings account with extra steps.
That is not failure — that is the shape of the thing. Left alone, the same habit produces $702,000 in its fourth decade alone.
Someone who invests for ten years and then never adds another dollar still finishes ahead of someone who starts a decade later and keeps paying in for thirty.
$5,000 a year for ten years, then never adds another dollar.
$5,000 a year, every year, for thirty-one years.
The early starter put in $105,000 less and still finished $55,980 ahead.
A habit beats a windfall, because a habit gets multiplied every month it runs.
Over 40 years at a 7% average annual return after inflation. The multiple is the same on every row because the multiplier is time, not the size of the cheque.
Seeing the date change when I adjusted my savings — that was the moment it clicked.

Your FIRE number estimates the investments needed to cover your spending. Your freedom date estimates when you could reach it. Try your own numbers above, free and without an account.
The 25× rule is a starting point: $50,000 in annual spending gives a $1.25 million target at a 4% withdrawal rate. It does not guarantee your money will last. Review the assumptions in the 4% rule guide before treating an estimate as a retirement plan.
How much you need to retire depends on where you live. Explore FIRE numbers and cost-of-living context for popular cities, or browse all city FIRE guides.
A FIRE (Financial Independence, Retire Early) calculator estimates how much you need invested to stop relying on a paycheck, and when you could reach that point. UntilFire turns your income, spending, and savings into a freedom date — the year work becomes optional — in about 60 seconds, no login required.
The most common FIRE rule is 25× your annual spending — the amount that lets you withdraw about 4% per year. If you spend $50,000 a year, your FIRE number is roughly $1.25 million. Your real target depends on your cost of living, taxes, and the lifestyle you want, which is why UntilFire personalizes it to you.
Your FIRE number is an estimate of the invested portfolio needed to cover your expected annual spending at a chosen withdrawal rate. At 4%, multiply spending by 25. This is a starting point, not a guarantee: retirement length, taxes, fees, inflation and market returns can change what you need.
Your freedom date is the estimated year your investments could support your expected spending. UntilFire lets you explore how changes to saving, spending or income could move that date. It is a projection based on assumptions, not a promised retirement year.
They're variations on the same goal. Coast FIRE means you've invested enough that growth alone reaches your number by traditional retirement age. Barista FIRE blends part-time work with portfolio income. Lean FIRE targets a frugal lifestyle, while Fat FIRE funds a more comfortable one. UntilFire helps you plan toward whichever fits your life.
