Quick answer: how Social Security is calculated

The benefit starts from your average indexed monthly earnings (AIME) and a 90% / 32% / 15% formula. With $80,000 average earnings over 35 years, your benefit at full retirement age (67) is about $2,879.00 a month.

Overview of the Social Security Calculator

Social Security retirement benefits are based on your 35 highest years of wage-indexed earnings. This calculator averages your earnings (capped at the $184,500 wage base) into AIME, applies the 2026 bend points of $1,286 and $7,749 to get your primary insurance amount (PIA), and then adjusts it for your claiming age — 30% less at 62 and 24% more at 70 for people with a full retirement age of 67.

Your actual benefit depends on your real earnings record and annual indexing — your statement at ssa.gov is the authority. Delaying a claim increases the monthly benefit for life. See also the Retirement Calculator, the RMD Calculator and the Pension Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Cap each year's earnings at the wage base ($184,500 for 2026) and average the highest 35 years (years with no earnings count as zero) to get AIME = total ÷ 420.
  2. PIA = 90% of AIME up to $1,286, plus 32% of AIME from $1,286 to $7,749, plus 15% above $7,749 (rounded down to the dime).
  3. Find your full retirement age: 66 for those born in 1954 or earlier, rising by 2 months a year to 67 for 1960 or later.
  4. Reduce the benefit for claiming early (5/9% per month for the first 36 months, 5/12% after) or raise it for delaying (2/3% per month up to age 70).
PIA = 0.90 × min(AIME, 1,286) + 0.32 × (min(AIME, 7,749) − 1,286) + 0.15 × (AIME − 7,749)

Social Security Calculator — Frequently Asked Questions

How is Social Security calculated?

From your 35 highest years of indexed earnings (AIME), a progressive formula gives the PIA, which is then adjusted for the age you claim.

What is full retirement age?

The age at which you receive 100% of your PIA: 66 for those born in 1954 or earlier, up to 67 for those born in 1960 or later.

How much less do I get if I claim at 62?

With a full retirement age of 67, claiming at 62 cuts your benefit by about 30%.

How much more do I get by waiting until 70?

About 8% more for each year you delay past full retirement age, up to age 70 — 24% more if your FRA is 67.

What are the 2026 bend points?

$1,286 and $7,749 for people who become eligible in 2026. They change each year.

Is this my official benefit?

No. It is a simplified estimate. Your Social Security statement at ssa.gov uses your actual earnings record.

How is the social security calculator calculated?

It uses the standard formula: PIA = 0.90 × min(AIME, 1,286) + 0.32 × (min(AIME, 7,749) − 1,286) + 0.15 × (AIME − 7,749) The full method and a worked example are shown on this page.

Is this financial advice?

No. The calculator gives estimates for planning and learning. Real offers vary by lender, product and date, so confirm the details with your bank, lender or a qualified adviser before deciding.

Can I use another currency?

Yes. The maths is identical in any currency; only the currency symbol shown in the results differs.

Is my data stored?

No. Everything is calculated in your browser and nothing you enter is uploaded or saved.
