How to use the retirement calculator

Enter your current age and target retirement age, current savings balance, monthly contribution, expected annual return, and desired withdrawal rate. The calculator projects your total savings and estimated income in retirement.

The 4% withdrawal rule

A common guideline is to withdraw 4% of your retirement savings per year. This rate was designed to make savings last 30+ years. Adjust the withdrawal rate based on your expected retirement length.

FAQ

What annual return should I use?

Historical US stock market returns average around 7% per year after inflation. For a balanced portfolio, 5-7% is a common assumption. Be conservative to avoid overestimating.

Does this account for inflation?

The calculator uses nominal returns. To account for inflation, subtract the expected inflation rate (typically 2-3%) from your annual return input.
