Frequently Asked Questions

What does "FIRE" actually stand for?+

Financial Independence, Retire Early. It is a massive movement focused on aggressively increasing savings rates (often saving 50%+ of your income) and investing strictly in low-cost, broad-market index funds to reach a state where you never have to work for money again.

Where does the 25x multiplier come from?+

The calculation for your "FIRE Number" is historically based on the famous Trinity Study. It proved that in the vast majority of historical economic scenarios, if a retiree withdraws 4% (or 1/25th) of an equity-heavy portfolio annually, it will never run out of money over a 30-year period.
