The 4% rule (Bengen Rule) suggests you can withdraw 4% of your retirement portfolio per year with a high probability of not running out of money over a 30-year retirement. Divide your balance by 25 to get the same number.

How is inflation adjustment calculated?

The future balance is divided by (1 + inflation rate)^years to express it in today's purchasing power, showing the real value of your savings.

What return rate should I use?

Historically, a diversified stock portfolio has returned about 7–10% annually before inflation. A conservative estimate of 6–7% is commonly used for planning.

Does this include Social Security?

No, this calculator focuses on personal savings and investments. Add expected Social Security benefits to the monthly income estimate separately.
