About

Money that buys your freedom

"FU money" is the amount that lets you walk away — from a bad job, a bad boss, or a bad situation — without the money being the thing that stops you. FU Money Calculator exists to turn that fuzzy idea into a concrete number, and then show you the fastest realistic path to reach it.

What you get

A growing toolbox of free calculators: the core FU Number calculator, the Freedom Runway tool, and a printable Goal Tracker, with more on the way. Each one is fast, interactive, and answers a single clear question.

Private by design

Everything you type runs in your own browser. We don't have accounts, and your numbers are never sent to or stored on our servers. Share a result only if you choose to — the share link encodes the inputs, nothing more.

Methodology

Our core math follows widely used financial-independence principles: the safe-withdrawal-rate framework (the "4% rule," equal to 25× annual spending) for the FU number, and standard compound-growth projections using real, after-inflation returns for timelines. We show our assumptions on every tool and let you change them.

Educational resource only — not financial advice. We are not financial advisors. Consult a qualified professional before making financial decisions.
