Social Security Calculator

Social Security claiming age calculator

This calculator compares U.S. retired-worker benefits from age 62 through age 70. Start with the monthly benefit shown for your full retirement age in your official Social Security estimate. The tool applies the SSA claiming-age adjustment to that amount and compares the cumulative value of each start age through the life expectancy you enter.

early reduction = 5/9 of 1% for each of the first 36 months before FRA, plus 5/12 of 1% for each additional month

delayed retirement credit for people born in 1943 or later = 2/3 of 1% for each month after FRA, stopping at age 70

Full retirement age by birth year

Full retirement age is 66 for people born from 1943 through 1954, then rises by two months for each birth year from 1955 through 1959. It is 67 for people born in 1960 or later. The SSA retirement age calculator notes a special convention for January 1 birthdays: use the previous birth year when determining FRA.

How the claim-age comparison works

The planner calculates an estimated monthly benefit at each possible claiming month, applies the cost-of-living adjustment you enter, and optionally compounds benefits already received at the entered investment return. It selects the claim age with the highest modeled value at life expectancy. That is a financial comparison only, not a recommendation.

The two-age mode is useful when your SSA account already provides distinct payment estimates. It compares cumulative benefits, investment-adjusted values, and the simple break-even age when the larger later payment catches up with benefits collected earlier. Taxes are not included.

2026 retirement earnings test

If you receive retirement benefits while working before full retirement age, SSA may withhold part of the benefit. In 2026, the lower annual exempt amount is $24,480, with $1 withheld for every $2 earned above that amount. In the year you reach FRA, the higher amount is $65,160 and $1 is withheld for every $3 above the limit, counting only earnings before the FRA month. Beginning with the FRA month, earnings no longer reduce benefits. See the SSA working while receiving benefits guidance.

SSA later recalculates the monthly benefit to credit months in which benefits were reduced or withheld. The earnings-test mode estimates current-year withholding only; it does not model that later adjustment, the special first-year monthly rule, or work outside the United States.

What this calculator does not estimate

It does not recreate your primary insurance amount from a 35-year earnings record, estimate disability or survivor benefits, model spousal coordination, determine eligibility, calculate Medicare premiums, or calculate federal and state tax on benefits. Actual payments also reflect SSA rounding and individual record details. Use the result for scenario comparison and verify decisions with SSA.

Frequently asked questions

Is age 70 always the best time to claim?

No. Delaying increases the monthly amount, but the financially preferable age depends on longevity, investment return, cash needs, health, work, taxes, and household or survivor considerations.

Why should I enter my SSA estimate instead of salary?

Retirement benefits depend on indexed earnings across up to 35 years, not one current salary. Your SSA record is a stronger starting point than a shortcut based only on today's pay.

Does the earnings test permanently lose withheld benefits?

SSA states that benefits are recalculated at full retirement age to credit months when benefits were withheld. This calculator does not estimate that later increase.

Does delaying after age 70 increase benefits?

No. Delayed retirement credits stop at age 70.
