All retirement & FIRE calculators
Six free calculators cover the core of a US FIRE plan: your FIRE number and years-to-FI, your Coast-FIRE date, compound investment growth, the 401(k) employer-match sweet spot, the Roth vs Traditional break-even, and a 4%-rule safe-withdrawal drawdown. All run in your browser and use the 2026 IRS limits. These are estimates, not financial advice.
Find the portfolio size that makes work optional, then estimate how many years of saving it takes to get there.
Coast FIRE CalculatorSee whether your invested savings can grow into a full retirement on their own — without another dollar of contributions.
Compound Interest & Investment Growth CalculatorProject how a starting balance plus regular contributions grows over time with compounding returns.
401(k) Employer Match MaximizerFind the contribution percentage that captures every dollar of your employer's 401(k) match — free money you do not want to leave behind.
Roth vs Traditional Break-Even CalculatorCompare after-tax outcomes of a Roth and a Traditional account and find the future tax rate where they break even.
4% Rule & Safe Withdrawal CalculatorEstimate the sustainable annual income from your portfolio and model a year-by-year drawdown.
