The honest part

The decade nobody warns you about.

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.

Which is why

Starting early beats saving more.

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.

FAQ

Good questions.

What is a freedom date?

The date when work can become optional based on your current income, spending, and savings. It's a starting line you can move closer with better choices.

How is this different from a calculator?

Most calculators stop at a number. UntilFire starts there and turns it into a plan: what matters, what to change next, and how to move forward.

Do I need an account?

No. You can see your freedom date and first move without creating an account. Create one when you want to save your plan and track progress.

Can I take my data with me?

Yes. From Profile you can export your transactions as a spreadsheet, or everything as one file, any time and free, whether or not you're on Pro. You can delete your account and data there too.

Is this financial advice?

No. UntilFire is planning software that helps you understand scenarios and tradeoffs. It does not replace a licensed financial adviser.

on that curve.

Finance your freedom

Understand your FIRE estimate

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.

FIRE calculator — frequently asked questions

What is a FIRE calculator?

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.

How much money do I need to retire early?

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.

What is my FIRE number?

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.

What is a freedom date?

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.

What are Coast, Barista, Lean, and Fat FIRE?

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.
