What's Your FIRE Number?
Your FIRE number is the amount of invested capital you need before you can stop relying on active income — the point where your safe withdrawal rate covers your annual expenses indefinitely.
The formula
FIRE number = annual expenses ÷ safe withdrawal rate.
At a 4% withdrawal rate, someone spending €30,000/year needs €750,000 invested. Lower your expenses or accept a lower withdrawal rate and the number moves — ClaryFIRE shows you both directions instantly, plus how long it takes to get there at your real savings rate.
