About FireLine

Why it exists

Financial independence comes down to two numbers: what you spend and what your portfolio can safely support. This calculator ties them together so you can see how savings rate and withdrawal rate move your target date.

FireLine is a free, independent web tool. Find the year you can stop working.

We build small, fast tools that run entirely in your browser: no sign-up, no data uploads. The site is funded by advertising and an optional ad-free premium plan.

Accuracy

We work hard to keep formulas and reference data up to date, and every guide shows when it was last updated. Results are estimates; always double-check important decisions with a qualified professional.
