    Social Security claiming calculator

    Compare retired-worker claiming ages from 62 through 70 using your SSA primary insurance amount, the full retirement age for your birth cohort, and the official early-reduction and delayed-credit schedules. Review lifetime totals, discounted value and the break-even age under your own COLA and longevity assumptions.

    Canonical equations
    The exact relationships implemented by this engine.

    PIA × [1 − min(m,36)·5/900 − max(m−36,0)·5/1200] · m is the number of months before full retirement age.

    PIA × [1 + d × c] · d months after full retirement age, capped at age 70; c is the cohort monthly credit.

    Σ benefitₜ / (1 + r)^(t/12) · Monthly payments discounted to age 62 at the entered annual rate r.

    benefitₜ = initial benefit × (1 + g)^⌊months from age 62 / 12⌋ · g is the user-entered COLA assumption; PIA is in age-62 dollars.

    finance methodology

    A clear path from inputs to results.

    Social Security claiming age changes the retired-worker benefit by a schedule set by birth cohort. Enter your primary insurance amount (PIA) from an SSA statement to compare the whole-dollar monthly check, lifetime benefits and present value for claims from age 62 through 70.

    Step-by-step methodWorked exampleAssumptions explained

    How to use

    1. Find your estimated monthly benefit at full retirement age and express it in age-62 dollars as the PIA baseline used by this model.
    2. Enter your birth year and mark January 1 if that is your birthday; SSA assigns that date to the prior cohort year for these age rules.
    3. Set the expected lifespan, annual cost-of-living adjustment and annual discount rate. COLA is projected from the age-62 baseline, including years before the claim.
    4. Review the table for each whole-year claiming age, then compare two ages in the cumulative-benefit chart.

    The formula

    Early benefit=PIA[1−min⁡(m,36)5900−max⁡(m−36,0)51200],Delayed benefit=PIA(1+dc)\text{Early benefit}=\text{PIA}\left[1-\min(m,36)\frac{5}{900}-\max(m-36,0)\frac{5}{1200}\right],\quad \text{Delayed benefit}=\text{PIA}(1+dc)

    Worked example

    $1,671 PIA, 1960 cohort, claiming at 62 or 70

    Inputs
    • PIA $1,671 per month · birth year 1960 · FRA 67 · lifespan 90 · 0% COLA · 0% discount.
    Calculation path
    1. 1

      At 62, the claim is 60 months before FRA: 36 × 5/9% + 24 × 5/12% = 30% reduction.

    2. 2

      The age-62 amount is $1,671 × 70% = $1,169.70, rounded down to $1,169 per month.

    3. 3

      At 70, 36 months of delayed credits add 36 × 8/12% = 24%, giving $1,671 × 1.24 = $2,072.04, rounded down to $2,072.

    4. 4

      Over 28 years to the 90th birthday, claiming at 62 pays $1,169 × 336 = $392,784; claiming at 70 pays $2,072 × 240 = $497,280.

    5. 5

      With no COLA or discount, the age-70 strategy catches up about 10 years and 4 months after age 70, at roughly age 80.4.

    Result

    Age 62: $1,169/month · age 70: $2,072/month · nominal lifetime totals: $392,784 and $497,280 through age 90.

    Interpreting the result

    A later claim trades years of smaller checks for a larger inflation-adjusted check for life. The highest present-value age depends on your lifespan, COLA and discount rate; the largest nominal total can be a different age. The break-even age compares total benefits received and does not decide the question for a household with taxes, earnings, spousal or survivor benefits.

    Assumptions & limitations

    • Enter the PIA shown by SSA. This tool does not estimate a benefit from an earnings record or calculate AIME and PIA.
    • The Social Security Administration birth-year full-retirement-age and delayed-credit tables are used. January 1 birthdays are assigned to the prior birth year.
    • Claim ages are compared at whole years from 62 through 70. Actual SSA adjustment factors are month-based; a specific claim month can differ.
    • Initial monthly benefits are rounded down to whole dollars. PIA is entered in age-62 purchasing power; the model applies the user-entered COLA once every 12 months from age 62, including before benefits start.
    • The model excludes the retirement earnings test, benefit taxation, Medicare premiums, spouse and survivor coordination, family maximums, and future law changes.
    • The present value discounts monthly payments to age 62 at the entered annual rate. It is a planning comparison, not an investment return or guarantee.

    Frequently asked questions

    What is the PIA?

    The primary insurance amount is the monthly retired-worker benefit payable at full retirement age before claiming-age adjustments. Use SSA’s estimate, converted to the age-62-dollar baseline used in this projection.

    How is claiming before full retirement age reduced?

    The benefit is reduced by 5/9 of 1% for each of the first 36 months before FRA, then by 5/12 of 1% for every additional month. For someone with FRA 67, claiming at 62 reduces the PIA by 30%.

    Does the highest present-value age tell me when to claim?

    It tells you which claim age has the largest discounted retired-worker benefit under the lifespan, COLA and discount rate you entered. Taxes, work income, spouse and survivor benefits, health and cash needs can change a household decision.

    Why does the calculator ask whether my birthday is January 1?

    SSA treats people born on January 1 as having been born in the prior year for full-retirement-age and bend-point rules. That can change the FRA cohort used in the reduction schedule.

    How do delayed retirement credits work?

    For people born in 1943 or later, delayed retirement credits add 8% for each full year after FRA, applied monthly, up to age 70. Earlier birth cohorts have smaller SSA-published credit rates.
