FI Calc is a calculator that simulates retirements using historical data, which is a strategy called "backtesting." The classic 4% Rule was derived from backtesting.

FI Calc is free. It is designed, built, supported, and maintained by one person (me, James. Nice to meet you!), and I work on it in my free time. If you've found value from the app or from email support, please consider donating to support the project.

Please note: donating does not unlock any new functionality in the app.

Thank you!
