Can You Retire Early?

A structured reality check for the FIRE movement's core claims.

Financial independence and early retirement are achievable goals — but the math is more demanding than the headlines suggest. Here is what the numbers actually require.

25–33×annual spending is the required portfolio range for early retirement — higher than standard retirement due to longer withdrawal periods and greater sequence-of-returns risk

The Situation

The Real Math of Early Retirement

FIRE (Financial Independence, Retire Early) is built on a straightforward principle: save enough that investment returns sustainably cover your expenses indefinitely. The challenge is that 'enough' is a precise number, not an approximation — and it requires a savings rate and timeline that most people significantly underestimate.

Early retirement is not primarily about sacrifice. It is about the savings rate you sustain for long enough to cross the threshold.
