Retirement & FIRE Number Calculator — Pro Edition

Work out the number that sets you free: your FI target, Coast and Lean and Fat FIRE variants, a year-by-year projection to age 90 and withdrawal-rate scenarios.

What makes this the Pro edition

Live cross-sheet formulas. Fill the input cells and every total, ratio and projection recalculates on its own. No manual maths anywhere.
A real dashboard. One tab that answers the question you bought this to answer, with a short plain-English note under every number telling you what it means and when to worry.
Dropdown categories. Consistent data every time, so a summary is never wrong because the same category got typed two different ways.
Excel and Google Sheets. Import instructions included. Also opens in Apple Numbers and LibreOffice Calc.
Ready to use out of the box. Currency formats, frozen headers, filters, banded rows and totals already set up.

Who it is for

Built for people who want one honest file instead of six half-finished ones — and who would rather spend ten minutes a week on their numbers than a weekend rebuilding a spreadsheet from scratch.
