When my parents were getting close to retirement, we started comparing what their Social Security checks might look like if they claimed at different ages. I made this calculator for them to answer one straightforward question: about how long would it take the larger monthly check to catch up with the payments they could have received by claiming earlier?
Try the calculator
Compare two claiming ages
Use the monthly estimates from your Social Security statement. The later estimate should be higher than the earlier one.
Break even age
Enter both monthly benefit estimates to compare.
This simple estimate holds each monthly amount flat. It is for comparison only and does not tell you when to claim.
How to use it
Enter the monthly benefit estimates shown for two different claiming ages on your Social Security statement. The earlier age goes first, and the later age goes second. The calculator shows the approximate age when the total payments from both choices would be equal.
The result is a simple comparison using the amounts you enter. It does not estimate your Social Security benefit. For a personalized estimate based on your earnings record, use the Social Security Administration’s retirement calculators or sign in to your my Social Security account.
What this comparison leaves out
This calculator holds each monthly amount flat over time. It does not account for cost of living adjustments, taxes, investment returns, work income, benefits for a spouse or survivor, or how long either person will live. Those details can change how the options compare, so treat the break even age as one helpful point of reference, not a recommendation about when to claim.
I built this for my parents because the choice is easier to talk through when you can see the basic math. If you’re making the same decision, start with your own estimate from Social Security and use this as a simple side by side comparison.
