Retirement Calculator

Your current balance and monthly contributions compound monthly at the expected return until retirement age, with contributions rising each year by the increase you set (to reflect raises). Because a dollar decades away buys less, we also show the balance in today's dollars — discounted by your inflation assumption — so the number means something you can picture.

The income estimate uses the 4% guideline: withdraw 4% of the portfolio in year one, then adjust for inflation annually — a rule that historically sustained a diversified portfolio for 30+ years. We add your expected Social Security or pension (entered in today's dollars) to show a realistic total monthly income.

U.S. stocks have averaged roughly 10% nominal (about 7% after inflation) over the last century, so 7% return with 3% inflation is a common all-stock baseline. Use lower figures for bond-heavy mixes, and remember that sequence-of-returns risk means real outcomes spread widely around any average — revisit the plan yearly.
