Working Backward From "Enough"

Retirement planning is really one question: how much needs to be saved so it lasts as long as you do. These fifteen calculators cover savings, withdrawal, and income-timing math for retirement.

Disclaimer: These calculators are for informational and educational purposes only and do not constitute financial advice. Consult a licensed financial advisor for guidance specific to your retirement plan.
The rule most retirement math is built around: the commonly cited "4% rule," based on historical market return research, suggests a portfolio can sustain roughly 4% in annual withdrawals (adjusted for inflation) without running out over a typical 30-year retirement. Worked backward, that means targeting approximately 25 times your annual expenses saved — a $50,000/year lifestyle implies a target of roughly $1.25 million. It is a planning guideline based on historical data, not a guarantee, which is why the FIRE Calculator and Retirement Planner Calculator let you test different withdrawal rates rather than assuming one fixed number.
