Retirement Calculator
See how your retirement savings could grow. Enter your age, planned retirement age, current savings, monthly contribution and expected return, and the calculator estimates your savings at retirement, how much came from growth, and a rough monthly income figure.
Monthly income estimate uses the 4% rule (withdraw 4% of savings per year). It is a rough guide, not financial advice.

Method: Projects savings with compound growth on the current balance plus future contributions; results are shown in nominal dollars unless an inflation adjustment is selected.
How it works
Your savings compound until retirement: the current balance grows at the expected return while each monthly contribution is added and also compounds. The estimated monthly income uses the 4% rule, withdrawing four percent of the final savings per year, which many planners use as a rough sustainable guide.
