FI Calc is a calculator that simulates retirements using historical data. The classic 4% rule was derived using this approach. You can use FI Calc to increase your confidence in your retirement plan.
This calculator is built by one person (me, James! Nice to meet you!), and I work on it in my free time. If you've found it useful, please consider donating to support its maintenance and development. Thank you!
