The Social Security formula 2026 turns your lifetime earnings into a monthly retirement benefit in three steps: it averages your 35 highest wage-indexed years into your Average Indexed Monthly Earnings (AIME), runs that average through a progressive bracket formula to set your Primary Insurance Amount (PIA), then raises or lowers that amount for the age you claim.
The Social Security formula 2026 has three steps. The Social Security Administration averages your 35 highest wage-indexed earnings years into your AIME, applies the progressive formula (90% of the first $1,286, 32% up to $7,749, then 15% above it) to produce your Primary Insurance Amount, then adjusts that amount for claiming age, from a 30% cut at 62 to a 24% increase at 70 (Source: SSA, 2026).
What is the Social Security formula for 2026?
The Social Security formula for 2026 is a three-step calculation the SSA applies to every retirement benefit. It converts a lifetime earnings record into a base benefit at full retirement age, then adjusts that base for when you actually claim. The three progressive percentages (90%, 32%, and 15%) apply at 2026 bend points of $1,286 and $7,749 (Source: SSA, “Primary Insurance Amount,” 2026).

The three steps run in this order:
- Step 1: AIME. Average your 35 highest wage-indexed earnings years into a monthly figure.
- 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.
The sections below walk through each step with 2026 figures and two worked dollar examples.
Step 1: How is your AIME (Average Indexed Monthly Earnings) calculated?
AIME is the monthly average of your 35 highest wage-indexed earnings years. The SSA indexes each past year for national wage growth, sums your 35 best indexed years, 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 earnings are multiplied by the national Average Wage Index (AWI) from the year you turn 60, divided by the AWI for that earlier year. A worker first eligible in 2026 is 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 toward AIME. 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: How do the 2026 bend points turn AIME into your PIA?
The 2026 bend points split your AIME into three brackets that are replaced at 90%, 32%, and 15%. For workers first eligible in 2026, the PIA equals 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, “Benefit Formula Bend Points,” 2026). The total is rounded down to the next lower dime.
The Primary Insurance Amount (PIA) is the benefit payable at your full retirement age. The two dollar figures where the replacement rate drops are the bend points, and they move each year with the AWI. The table below shows the bend points by year of first eligibility.
| Year first eligible (age 62) | First bend point | Second bend point | Formula tiers |
|---|---|---|---|
| 2024 | $1,174 | $7,078 | 90% / 32% / 15% |
| 2025 | $1,226 | $7,391 | 90% / 32% / 15% |
| 2026 | $1,286 | $7,749 | 90% / 32% / 15% |
One rule the SSA stresses is easy to miss: your bend points lock in the year you turn 62, not the year you claim. The percentages (90%, 32%, 15%) never change, but the two dollar thresholds are fixed by your year of first eligibility (age 62). A worker who turns 62 in 2026 uses the $1,286 and $7,749 bend points even if they wait until 67 or 70 to file (Source: SSA, “Benefit Formula Bend Points,” 2026). Later bend-point increases do not reset your figures.
Worked example: converting AIME to PIA in 2026
Take a mid-range 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:
- 90% of $1,286 = $1,157.40
- 32% of ($6,000 minus $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 next lower dime = $2,665.80 PIA
Now take a high earner with an AIME of $13,600 who reaches all three brackets, including the 15% tier above $7,749:
- 90% of $1,286 = $1,157.40
- 32% of ($7,749 minus $1,286) = 32% of $6,463 = $2,068.16
- 15% of ($13,600 minus $7,749) = 15% of $5,851 = $877.65
- Total $4,103.21, rounded down to the next lower dime = $4,103.20 PIA
The high earner’s PIA sits near the 2026 ceiling, yet the extra AIME above the second bend point is replaced at only 15 cents on the dollar. That gap between the 90% and 15% tiers is the progressive design in action, replacing a larger share of earnings for lower lifetime earners.
Step 3: How does your claiming age change the benefit?
Your PIA is the benefit at full retirement age (FRA), but you can claim from age 62 to 70, and the age you choose changes the check permanently. Claiming at 62 with an FRA of 67 cuts the benefit by 30%. Delaying past FRA adds delayed retirement credits worth 8% per year up to age 70, a 24% increase for a worker with an FRA of 67 (Source: SSA, “Early or Late Retirement,” 2026).
FRA depends on your birth year, as shown below.
| Birth year | Full retirement age |
|---|---|
| 1943 to 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. The table below tracks a $1,000 PIA across every claiming age for a worker with an FRA of 67.
| Claiming age (FRA 67) | Adjustment | Monthly benefit from a $1,000 PIA |
|---|---|---|
| 62 | minus 30% | $700 |
| 63 | minus 25% | $750 |
| 64 | minus 20% | $800 |
| 65 | minus 13.3% | $867 |
| 66 | minus 6.7% | $933 |
| 67 (FRA) | 0% | $1,000 |
| 68 | plus 8% | $1,080 |
| 69 | plus 16% | $1,160 |
| 70 | plus 24% | $1,240 |
Source: SSA, “Early or Late Retirement,” 2026.
At what age do you get 100% of your Social Security?
You receive 100% of your Primary Insurance Amount at your full retirement age. FRA is 67 for anyone born in 1960 or later, and it ranges from 66 to 66 and 10 months for those born between 1943 and 1959 (Source: SSA, “Benefit Reduction for Early Retirement,” 2026). Claiming before FRA permanently reduces the benefit; waiting past FRA up to 70 adds delayed retirement credits.
FRA is the pivot point of the whole formula: below it the reduction schedule applies, above it the 8% per year credits apply, up to age 70.
What is the maximum Social Security benefit in 2026?
The maximum Social Security benefit in 2026 is about $5,181 per month for a worker who delays to age 70, and $4,152 per month for one who claims exactly at full retirement age (Source: SSA, 2026). Reaching either figure requires earning at or above the taxable maximum ($184,500 in 2026) for 35 years.
The two maximum figures reflect the claiming-age adjustment applied to the highest possible PIA. A worker who claims at 62 receives a much lower maximum, because the 30% early-claiming cut applies to that same top PIA.
| Claiming age | 2026 maximum monthly benefit |
|---|---|
| 62 | about $2,969 |
| 67 (full retirement age) | $4,152 |
| 70 | about $5,181 |
Source: SSA, 2026 COLA Fact Sheet and SSA benefit tables, 2026.
Most workers do not reach these ceilings, because few earn the taxable maximum for 35 years. The 2026 cost-of-living adjustment (COLA) of 2.8% is applied to benefits after the PIA is set (Source: SSA, 2026 COLA Fact Sheet).
Who qualifies: the 40-credit rule
To qualify for a retirement benefit you need 40 work credits, roughly 10 years of covered work. You can earn up to 4 credits per year, and in 2026 one credit is granted for every $1,890 in covered earnings (Source: SSA, “Quarter of Coverage,” 2026). Reaching 40 credits makes you insured; your actual benefit still depends on the 35-year earnings average.
Earning $7,560 in covered wages in 2026 (four times $1,890) locks in the maximum four credits for the year. Credits never expire once earned, so a worker who leaves and re-enters the workforce keeps every credit already banked.
How do I estimate my own benefit?
An estimate built from your actual earnings record is more accurate than the general formula. You can sign in to your free my Social Security account at ssa.gov to see a benefit estimate built from your real wages, or use the SSA Quick Calculator for a fast projection (Source: SSA, 2026). Third-party tools from AARP, SmartAsset, and NerdWallet offer additional estimates.
To estimate your benefit, take these steps:
- Open your my Social Security account at ssa.gov for a personalized estimate at 62, FRA, and 70.
- Use the SSA Quick Calculator for a fast figure if you are not ready to open an account.
- Cross-check with an AARP or SmartAsset calculator to model different claiming ages.
Because claiming age can swing the check by more than 70% between age 62 and 70, modeling several ages often matters more than the single FRA estimate. Coordinating the claim date with account withdrawals is where a retirement tax plan can do its work.
What the Social Security formula leaves out
The three-step formula produces your gross PIA and stops there. It does not account for the 2025 repeal of two public-pension offsets, the federal income tax on part of many benefits, or the spousal and survivor benefits derived from the same PIA. Each of these can change what a household actually keeps (Source: SSA and IRS, 2026).
WEP and GPO were repealed in 2025. The Windfall Elimination Provision and the Government Pension Offset once reduced benefits for many public-sector workers with a non-covered pension. The Social Security Fairness Act, signed January 5, 2025, repealed both, so affected teachers, firefighters, and police officers are no longer subject to those cuts (Source: SSA, “Social Security Fairness Act,” 2025).
Taxation of benefits. 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% above $34,000 (single) or $44,000 (joint) (Source: IRS Publication 915, 2025). These thresholds are set by statute and are not indexed for inflation, so more retirees cross them over time. The lower-income years before benefits and required minimum distributions begin can open a planning window; some households use it for a Roth conversion sized to their bracket, which is taxable ordinary income in the year it is done but can reduce later taxable and provisional income. A large conversion is taxable in the year it is done and can raise that year’s net investment income tax exposure, while reducing future required minimum distributions.
Spousal and survivor benefits. Both derive from the worker’s PIA, not a separate formula. A spousal benefit can be worth up to 50% of the higher earner’s PIA at the spouse’s full retirement age, and a survivor benefit up to 100% of the deceased worker’s benefit (Source: SSA, “Benefits for Spouses” and “Survivor Benefits,” 2026).

Frequently asked questions
These answers summarize the Social Security formula 2026 using SSA figures for workers first eligible in 2026 and describe general situations rather than any individual earnings record.
What is the Social Security formula for 2026?
The Social Security formula for 2026 has three steps. The SSA averages your 35 highest wage-indexed earnings years into your AIME, applies the progressive formula (90% of the first $1,286, 32% up to $7,749, then 15% above it) to set your Primary Insurance Amount, then adjusts that amount for claiming age (Source: SSA, 2026). A 2.8% COLA is added after eligibility.
What are the 2026 bend points?
The 2026 bend points are $1,286 and $7,749 for workers first eligible at age 62 in 2026 (Source: SSA, “Benefit Formula Bend Points,” 2026). AIME below $1,286 is replaced at 90%, AIME between $1,286 and $7,749 at 32%, and AIME above $7,749 at 15%. These two dollar thresholds move each year with the national Average Wage Index.
How is AIME calculated?
AIME is calculated by indexing each past year of earnings for national wage growth, selecting your 35 highest indexed years, summing them, and dividing by 420 months (Source: SSA, 2026). The result is rounded down to the next lower dollar. Only earnings up to each year’s taxable maximum ($184,500 in 2026) count, and missing years are entered as zeros.
How many years of earnings does Social Security use?
Social Security 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. Working extra higher-earning years can replace earlier low years.
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 66 and 10 months for earlier birth years (Source: SSA, “Benefit Reduction for Early Retirement,” 2026). Claiming earlier reduces the benefit; delaying past FRA to age 70 adds delayed retirement credits.
What is the maximum Social Security benefit in 2026?
The maximum Social Security benefit in 2026 is about $5,181 per month at age 70 and $4,152 per month at full retirement age (Source: SSA, 2026). Both require earnings at or above the taxable maximum of $184,500 for 35 years. A worker claiming at 62 receives a much lower maximum because the early-claiming reduction applies.
How do I calculate my Social Security benefit amount?
Use your my Social Security account at ssa.gov for a figure built from your real earnings record, or the SSA Quick Calculator for a fast projection (Source: SSA, 2026). To do it manually, find your AIME from your 35 best indexed years, apply the 2026 bend-point formula (90% / 32% / 15%), then adjust for your claiming age.
Are bend points locked in at age 62?
Yes. Your bend points lock in the year you turn 62 (your year of first eligibility), not the year you claim (Source: SSA, “Benefit Formula Bend Points,” 2026). A worker who turns 62 in 2026 uses the $1,286 and $7,749 bend points even if they file at 67 or 70. Later annual increases to the bend points do not reset your figures.
