Calculate the average annual return on your investments over multiple time periods.
Enter your starting value, ending value, time period, and any major contributions or withdrawals if the calculator supports them. This gives you a cleaner picture of how the investment actually performed.
Compare the average return with a benchmark such as the S&P 500, a target retirement return, or the return you assumed in your financial plan. Context matters more than the raw percentage alone.
Use the result to evaluate process, not just outcome. A weak average return may suggest high fees, too much cash drag, poor timing, or simply a conservative allocation that matched your risk tolerance.
