Social Security Benefits Calculator

How claiming age changes your Social Security benefit

Your benefit amount depends on two things: your earnings history — which determines your Primary Insurance Amount (PIA) — and the age you claim. The Social Security Administration applies the same set of actuarial adjustments to every retiree's PIA, and this calculator models those rules directly.

If you claim at your Full Retirement Age (FRA) — 67 for anyone born in 1960 or later — you receive 100% of your PIA. Claiming earlier permanently reduces your monthly check. Claiming later permanently increases it.

• Claiming at 62. The earliest age you can take retirement benefits. The reduction is roughly 30% for someone with an FRA of 67. A $2,000 FRA benefit becomes about $1,400. If you continue working, the earnings test may further reduce checks until you reach FRA. The advantage is more years of payments, which can matter if you have shorter life expectancy or need to bridge an income gap.
• Claiming at FRA (67). You receive your full calculated benefit with no reduction. The earnings test no longer applies, so you can work without losing checks.
• Claiming at 70. Each year you delay past FRA earns an 8% Delayed Retirement Credit, capped at age 70. Waiting from 67 to 70 increases your monthly benefit by 24%. There is no further increase after 70.

These reductions and credits come directly from SSA's published rules: the early-claiming reduction formula is set out in SSA's Retirement Age and Benefit Reduction planner (codified at 20 CFR § 404.410), and Delayed Retirement Credits are documented in SSA's Delayed Retirement Credits planner (20 CFR § 404.313).

The table below assumes a Full Retirement Age of 67 (anyone born in 1960 or later) and a $2,000 FRA benefit, so you can see the exact percentage and dollar effect of every claiming age from 62 to 70.

Each year of waiting between 62 and 70 is worth roughly 7-8 percentage points of PIA — the gap between claiming at 62 and 70 is 54 points, or $1,080 a month on this example.

What this calculator does and doesn't do

The calculator applies SSA's published reduction and credit factors to the benefit estimate you provide. The most accurate input is the FRA estimate from your my Social Security account at ssa.gov, which reflects your real earnings record. If you don't have that, the calculator can use an income-based approximation, but the result will be less precise.

The numbers reflect base retirement benefits only. They do not model:

• Future cost-of-living adjustments (COLA) — SSA has not published future-year COLAs, so projections beyond the claiming year aren't simulated.
• Spousal or survivor benefits — those follow separate rules. Use the Spousal Calculator for couples.
• Taxation of benefits — up to 85% of Social Security can be taxable depending on your combined income.
• Means-tested programs like Medicare IRMAA surcharges or Supplemental Security Income.

Full Retirement Age by birth year

The percentages in the table above assume an FRA of 67. Your own FRA depends on your birth year — anyone born in 1943 through 1954 has an FRA of 66, and it steps up by two months per birth year after that until it reaches 67 for anyone born in 1960 or later.

If your FRA is 66 rather than 67, the reduction and credit percentages in the benefit-by-age table shift by the same number of months — the calculator adjusts automatically once you enter your birth year.

Choosing your claiming age

The right age depends on your health, life expectancy, other retirement income, and whether you plan to keep working. The break-even age — when delayed claiming overtakes early claiming on lifetime totals — is typically the late 70s to early 80s. If you expect to live past that, waiting usually pays more in lifetime benefits. If you need the income earlier or expect a shorter retirement, claiming earlier may be the better choice. The calculator's lifetime totals at each age are designed to make this comparison concrete for your situation.

Retirement earnings test limits (2026)

If you claim before FRA and keep working, SSA temporarily withholds part of your benefit once your earnings pass an annual limit — this is the retirement earnings test. The limit is higher in the calendar year you reach FRA, and the test stops applying entirely starting the month you reach FRA. Current exempt amounts are published in SSA's Exempt Amounts Under the Earnings Test.

Withheld benefits are not lost — starting at FRA, SSA recalculates your monthly benefit upward to credit back the months withheld, so the earnings test mainly affects cash flow timing, not your lifetime total.
