What is the FIRE Method?
FIRE stands for Financial Independence, Retire Early. The core idea is simple: save and invest aggressively until your portfolio generates enough passive income to cover your living expenses indefinitely. The most widely used rule is the 4% rule — if you can live on 4% of your portfolio per year, you are financially independent.
How to Calculate Your FIRE Number
Your FIRE number is 25 times your annual expenses. If you spend $60,000 per year, you need $1,500,000 invested. This is derived from the 4% rule: $1,500,000 × 4% = $60,000. The calculator above computes this automatically based on your annual expenses input.
The Role of Compound Interest in Early Retirement
Compound interest is the engine behind every FIRE plan. As your portfolio grows, the returns it generates become larger each year — without any additional contribution from you. This snowball effect means that the last few years before retirement often add more to your portfolio than the first decade of saving.
How to Retire Earlier
Three levers control your retirement date: how much you save each month, your investment return rate, and your planned annual expenses in retirement. Reducing expenses has a double impact — it lowers your FIRE number and frees up more money to invest. Even small reductions in annual spending can move your retirement date forward by years.
