When does waiting pay off?
Compare Social Security claiming ages with your family’s longevity in mind. Find the age that maximizes total benefits under your assumptions.
How this comparison works
“Best” means the highest cumulative gross Social Security benefit through your selected lifespan. Claiming benefits and stopping work are separate decisions; this does not determine when you can afford to retire.
Assumptions & important considerations
Total = monthly estimate × 12 × years from claiming age to planning lifespan. Payments are modeled from each birthday until the selected birthday, with no payment in the month of death. All amounts are constant in today’s dollars; no additional COLA, investment return, or discount rate is applied. Calendar years are approximate: birth year + claiming age.
Taxes, Medicare premiums, earnings-test withholding, future earnings changes, spousal and survivor benefits, health, and savings needs are not modeled. Use estimates with consistent future-work and dollar assumptions. Whole-year comparisons omit exact claiming-month rules. Results are educational, not personalized financial advice.
SSA notes that there is no best claiming age for everyone; family history, lifestyle, other income, and benefit eligibility matter. Delayed retirement increases stop at 70.
