FIRECalc
What it is
FIRECalc is a free web calculator for assessing whether savings, planned spending, and other resources could support retirement across historical market conditions. It compares plans with market data beginning in 1871 and reports how often a portfolio would have remained funded for the chosen term across historical starting years. Users can include Social Security, pensions, and other income or spending adjustments, then select inflation-adjusted constant spending, Bernicke's Reality Retirement Plan, or withdrawals based on a percentage of the remaining portfolio. Portfolio settings include historical investments, fees, and consistent or random returns. Planning inputs can cover a future retirement date, contributions before retirement, and future lump-sum portfolio changes. Defaults use 75% stock index and 25% bond funds, a 0.18% fund fee, and inflation-adjusted spending over 30 years. The homepage reports data through January 1, 2026, updated April 17, 2026. FIRECalc applies historical data rather than predicting future returns; it does not provide tax planning or account synchronization. It says it does not store financial entries.
