Before You Begin

  • Results are estimates, not official SSA calculations. This tool never promises that a particular age maximizes your benefits and never automatically recommends delaying until 70.
  • Get your actual full-retirement-age benefit estimate from your official my Social Security account rather than relying on this tool to reconstruct your earnings history.
  • Health, employment, cash needs, marital status, survivor protection, and other retirement assets can all change the right decision for you — this tool doesn't rely solely on average life expectancy.
  • Social Security assumptions used here (full retirement age table, reduction and delayed-credit formulas) were last reviewed September 2026. Confirm current rules at ssa.gov.
  • Everything you enter stays in your own browser on this device. We don't send it to a server or store it on our end. Closing your browser's site data, or using "Clear my data" below, permanently deletes it.

A note on guardrails These results are estimates, not official SSA calculations. This tool never promises that a particular age maximizes your benefits, never relies solely on average life expectancy, and never automatically recommends delaying until 70. Health, employment, cash needs, marital status, survivor protection, and other retirement assets can all change the right decision for you. Visit the official SSA calculators and your Social Security account before deciding.
