Is FIRECalc still accurate in 2026?
The methodology (historical returns from 1871-present) is still valid and updated annually. The UI has not been modernized since 2002, but the engine itself is accurate and widely used as a reference.
Does FIRECalc account for taxes?
No. FIRECalc models your pre-tax portfolio. You need to adjust your withdrawal rate or spending to reflect your expected tax drag. EnoughMoney models taxes explicitly.
Which is better, FIRECalc or cFIREsim?
Both are free, both use historical data. FIRECalc is the older and more conservative; cFIREsim has more customization and modern UI. Both are respected by the FIRE community.
