How this calculator works

Target = annual spending ÷ safe withdrawal rate

safe withdrawal rate
the share of the portfolio you plan to spend each year

Important considerations

  • Healthcare and long retirements make early independence more demanding than the arithmetic suggests.
  • Spending, not income, drives the target — every dollar cut lowers it by 25 at a 4% rate.

Frequently asked questions

Why divide by the withdrawal rate?

It is the inverse of the multiple you need: 4% implies 25 times annual spending.
