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.

Finance your freedom
UntilFire is a free FIRE calculator and personal finance planner for anyone chasing financial independence and early retirement. Enter your income, spending, and savings, and we'll show your FIRE number, your freedom date, and the single move that brings early retirement closer — no account needed.
Most calculators stop at a number. UntilFire does it with you: a clear path, a next move, and continuity toward work optionality — built on the same 25× rule and 4% safe withdrawal math the FIRE community trusts.
Income, monthly spending or savings, and current net worth. Location and age are optional.
We estimate your FIRE number with the 25× rule and project the year work becomes optional.
See how saving more, spending less, or earning more pulls your retirement date earlier.
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 the portfolio size that can fund your lifestyle indefinitely at a safe withdrawal rate. Multiply your expected annual expenses by 25 for a quick estimate, or run the calculator above for a number adjusted to your city, income, and savings rate.
Your freedom date is the year you could stop working for money because your investments cover your expenses. It moves earlier when you raise your savings rate, lower your spending, or grow your income — and UntilFire shows you exactly which move brings it closer.
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.
