How is Social Security calculated? The Social Security Administration turns your lifetime earnings into a monthly retirement benefit through a three-step formula: it averages your 35 highest wage-indexed earnings years, runs that average through a progressive bracket formula to find your base benefit, then raises or lowers that base depending on the age you claim.
Social Security retirement benefits are calculated in three steps. The SSA averages your 35 highest wage-indexed earnings years into your Average Indexed Monthly Earnings (AIME), applies the 2026 progressive formula (90%, 32%, 15%) at bend points of $1,286 and $7,749 to produce your Primary Insurance Amount, then adjusts that amount for the age you claim (Source: SSA, 2026).
The three-step formula for how Social Security is calculated
Every retirement benefit runs through the same three steps, in order: Step 1 computes your Average Indexed Monthly Earnings (AIME), Step 2 converts AIME into your Primary Insurance Amount (PIA) using bracket percentages, and Step 3 adjusts the PIA up or down for your claiming age (Source: SSA, “Social Security Benefit Amounts,” 2026). The steps below walk through each one with 2026 figures and a worked dollar example.

- Step 1: AIME – average your 35 highest wage-indexed earnings years.
- Step 2: PIA – apply the 90% / 32% / 15% bend-point formula to that average.
- Step 3: Claiming-age adjustment – reduce the PIA for early claiming or increase it for delaying.
Step 1: Average Indexed Monthly Earnings (AIME)
AIME is the monthly average of your 35 highest-earning years after each year is indexed for national wage growth. The SSA sums those indexed years and divides by 420 months (35 years times 12), then rounds down to the next lower dollar (Source: SSA, “Social Security Benefit Amounts,” 2026). This average, not any single year’s salary, drives the benefit.
Indexing restates older earnings in today’s wage terms. Each prior year’s actual earnings are multiplied by the national Average Wage Index (AWI) from the year you turn 60, divided by the AWI for that earlier year. For a worker first eligible in 2026, earnings are indexed using the 2024 AWI of $69,846.57 (Source: SSA, “National Average Wage Index,” 2024).
If you worked fewer than 35 years, the SSA fills each missing year with a zero before averaging, which pulls the average down (Source: SSA, 2026). Only earnings up to each year’s taxable maximum count. For 2026 that cap is $184,500, up from $176,100 in 2025 (Source: SSA, “Contribution and Benefit Base,” 2026). Wages above the cap neither pay Social Security tax nor raise your benefit.
Step 2: Primary Insurance Amount and the 2026 bend points
The Primary Insurance Amount (PIA) is the monthly benefit payable at your full retirement age, and it comes from applying three bracket percentages to your AIME. For workers first eligible in 2026, the formula is 90% of the first $1,286 of AIME, plus 32% of AIME between $1,286 and $7,749, plus 15% of AIME above $7,749 (Source: SSA, “Primary Insurance Amount,” 2026). The result is rounded down to the nearest dime.
The two dollar figures where the percentages change are the bend points, and they move each year with the AWI. Note the freshness gap here: some published guides still cite the 2024 or 2025 bend points. The table below shows the current SSA figures by year of first eligibility.
| Year first eligible (age 62) | First bend point | Second bend point |
|---|---|---|
| 2024 | $1,174 | $7,078 |
| 2025 | $1,226 | $7,391 |
| 2026 | $1,286 | $7,749 |
Source: SSA, “Benefit Formula Bend Points,” 2026.
Worked example: converting AIME to PIA in 2026
Take a sample worker with an AIME of $6,000 who is first eligible in 2026. The 90% band covers the first $1,286, the 32% band covers the earnings up to $6,000, and the 15% band does not apply because the AIME sits below $7,749. Applying the 2026 formula:
- 90% of $1,286 = $1,157.40
- 32% of ($6,000 – $1,286) = 32% of $4,714 = $1,508.48
- 15% band: $0 (AIME is below the second bend point)
- Total $2,665.88, rounded down to the nearest dime = $2,665.80 PIA
The design is progressive on purpose. The 90% replacement rate on the first tranche of AIME means the formula replaces a much larger share of earnings for lower lifetime earners than for higher earners (Source: SSA, “Primary Insurance Amount,” 2026). The chart below shows how each dollar band is replaced at a different rate.
Step 3: Full retirement age and the claiming-age adjustment
Your PIA is the benefit at full retirement age (FRA), but you can claim as early as 62 or as late as 70, and the age you choose changes the monthly check. Claiming before FRA permanently reduces the benefit; delaying past FRA adds delayed retirement credits worth 8.0% per year for workers born 1943 or later, up to age 70 (Source: SSA, “Early or Late Retirement,” 2026).
FRA depends on your birth year, as shown below.
| Birth year | Full retirement age |
|---|---|
| 1943-1954 | 66 |
| 1955 | 66 and 2 months |
| 1957 | 66 and 6 months |
| 1959 | 66 and 10 months |
| 1960 and later | 67 |
Source: SSA, “Benefit Reduction for Early Retirement,” 2026.
The early-claiming reduction is 5/9 of 1% per month for the first 36 months before FRA, then 5/12 of 1% per month beyond that. For a worker with an FRA of 67, claiming at 62 (60 months early) cuts the benefit by 30%, so a $1,000 PIA becomes $700 (Source: SSA, “Early or Late Retirement,” 2026). Waiting until 70 instead adds three years of 8% credits, lifting that same $1,000 PIA to $1,240. The chart below tracks a $1,000 PIA across every claiming age for someone with an FRA of 67.
Who qualifies: the 40-credit rule
Before any formula runs, you must be insured for retirement benefits, which takes 40 work credits, roughly 10 years of covered work. You can earn a maximum of 4 credits per year, and in 2026 one credit is granted for $1,890 in covered earnings (Source: SSA, “Quarter of Coverage,” 2026). Reaching 40 credits qualifies you; your actual benefit still depends on the 35-year earnings average described above.
2026 figures that shape the result
Three current numbers frame the calculation for 2026. The taxable maximum, the ceiling on earnings that count, is $184,500 (Source: SSA, “Contribution and Benefit Base,” 2026). The most a worker retiring exactly at full retirement age in 2026 can receive is $4,152 per month (Source: SSA, 2026 COLA Fact Sheet). The 2026 cost-of-living adjustment (COLA) is 2.8%, announced October 24, 2025 (Source: SSA, 2026 COLA Fact Sheet).
COLA is applied after your PIA is set. Once you are eligible, annual COLAs raise the benefit to keep pace with inflation, so the figure you first calculate is a starting point rather than a fixed number.
What the standard formula leaves out
The three-step formula produces your gross Primary Insurance Amount, but it stops there. Three separate factors can change what a household actually receives or keeps: the 2025 repeal of two public-pension offset rules, the federal income tax that applies to part of many benefits, and the spousal and survivor benefits that derive from the same PIA. Each is outlined below.
WEP and GPO were repealed in 2025
Two long-standing rules, the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO), once reduced Social Security benefits for many public-sector workers who also earned a pension from non-covered employment. The Social Security Fairness Act, signed January 5, 2025, repealed both provisions, so affected workers and spouses are no longer subject to those reductions (Source: SSA, “Social Security Fairness Act,” 2025).
The offsets had applied to some teachers, firefighters, and police officers whose pensions came from work not covered by Social Security. Anyone whose past estimates assumed a WEP or GPO cut may now see a different figure.
Taxation of benefits
Your gross benefit is not always your net benefit, because part of it can be taxable. Under IRC Section 86, up to 50% of benefits can be taxable once “provisional income” exceeds $25,000 (single) or $32,000 (married filing jointly), and up to 85% can be taxable above $34,000 (single) or $44,000 (joint) (Source: IRS Publication 915, 2025). These thresholds are fixed by statute and are not indexed for inflation, so more retirees cross them over time. The interaction of benefits and other income is covered in our explainer on the Social Security tax torpedo.
Because the taxation thresholds are not indexed, the years between retiring and starting benefits or required minimum distributions are a lower-income window that some households use for tax planning. One approach the rules allow is a Roth conversion during that window, which is included in taxable income the year it is done but can reduce later taxable income and future provisional income, depending on individual circumstances. Higher income in a given year can also affect Medicare IRMAA surcharges and the timing of required minimum distributions.
Spousal and survivor benefits
Spousal and survivor benefits are both derived from the worker’s PIA, not a separate formula. A spousal benefit can be worth up to 50% of the higher earner’s PIA if the spouse claims at their own full retirement age, and it is reduced for claiming earlier (Source: SSA, “Benefits for Spouses,” 2026). A survivor benefit can be worth up to 100% of the deceased worker’s benefit (Source: SSA, “Survivor Benefits,” 2026). Both trace directly back to the PIA produced in Step 2.

Frequently asked questions
These answers summarize how Social Security retirement benefits are calculated for 2026, using the SSA three-step method of Average Indexed Monthly Earnings, the Primary Insurance Amount, and the claiming-age adjustment. Each response reflects figures published by the Social Security Administration for workers first eligible in 2026 and describes general situations rather than any individual earnings record.
How much Social Security will I get if I make $60,000 a year?
There is no single answer, because the benefit reflects your 35 highest wage-indexed years, not one year’s salary. Two people who each earn about $60,000 can receive different amounts depending on their full earnings history and claiming age. Only an estimate built from your actual earnings record is accurate; the SSA my Social Security account and Quick Calculator generate personalized figures (Source: SSA, 2026).
How is Social Security calculated for retirement?
Retirement benefits use three steps. The SSA averages your 35 highest wage-indexed earnings years into your AIME, applies the 2026 bend-point formula (90% / 32% / 15% at $1,286 and $7,749) to get your Primary Insurance Amount, then adjusts that amount for the age you claim (Source: SSA, 2026). COLA is added after eligibility.
What is the average Social Security benefit at age 62?
Claiming at 62 produces a permanently reduced benefit rather than a fixed average. For someone with a full retirement age of 67, filing at 62 cuts the Primary Insurance Amount by 30%, so a $1,000 PIA becomes $700 (Source: SSA, “Early or Late Retirement,” 2026). Your own reduced amount depends on your earnings record and exact birth date.
How many years does Social Security use to calculate benefits?
The SSA uses your 35 highest wage-indexed earnings years, dividing the indexed total by 420 months to reach your AIME (Source: SSA, 2026). If you worked fewer than 35 years, each missing year is entered as a zero, which lowers the average and the resulting benefit.
How do I calculate my Social Security benefit amount?
You can work the three steps by hand, or use SSA tools for an exact figure. The my Social Security account applies your real earnings record, and the SSA Quick Calculator and online benefits estimator give quick projections (Source: SSA, 2026). Doing it manually means finding your AIME, applying the 2026 bend-point formula, then adjusting for claiming age.
What is the maximum Social Security benefit?
The most a worker retiring exactly at full retirement age in 2026 can receive is $4,152 per month (Source: SSA, 2026 COLA Fact Sheet). Reaching it requires earnings at or above the taxable maximum, which is $184,500 in 2026, for 35 years. Delaying past full retirement age to 70 can produce a higher check through delayed retirement credits.
Is Social Security based on your highest 35 years of earnings?
Yes. The AIME calculation selects your 35 highest wage-indexed years, so lower-earning or zero years can be excluded once you have more than 35 years on record (Source: SSA, 2026). Working additional years at higher indexed earnings can replace an earlier low year and modestly raise the average.
At what age do you get 100% of your Social Security benefits?
You receive 100% of your Primary Insurance Amount at your full retirement age, which is 67 for anyone born in 1960 or later and between 66 and 67 for earlier birth years (Source: SSA, “Benefit Reduction for Early Retirement,” 2026). Claiming earlier reduces it; delaying past FRA up to age 70 adds delayed retirement credits.
