Social Security retirement benefits start with your covered earnings record—not your last paycheck or a flat percentage of income. The Social Security Administration (SSA) wage-indexes eligible past earnings, generally uses your highest 35 years to calculate average indexed monthly earnings (AIME), and applies a formula to produce your primary insurance amount (PIA). Your claiming age, cost-of-living adjustments (COLAs), and rounding rules then affect the monthly amount paid. The 2026 formula values apply only to people first eligible in 2026; your own estimate depends on your earnings record, birth date, and benefit start date.
How are Social Security retirement benefits calculated?
The standard retired-worker calculation moves through three different amounts:

- Indexed earnings: Past covered earnings are adjusted under SSA wage-indexing rules so eligible earlier earnings can be compared at later wage levels.
- AIME: The average indexed monthly earnings figure, based generally on the highest 35 years of indexed earnings.
- PIA and payable benefit: SSA applies a progressive formula to AIME to determine the primary insurance amount, then adjusts the result for claiming age and other applicable rules.
AIME is not your monthly check. The PIA is the formula amount associated with claiming at full retirement age (FRA), before applicable rounding; the amount actually payable can differ because you claim earlier or later and because COLAs and rounding rules apply. SSA defines PIA as the benefit a person would receive if they began retirement benefits at normal retirement age, before rounding down to a whole dollar. In SSA’s words, “The ‘primary insurance amount’ (PIA) is the benefit (before rounding down to next lower whole dollar) a person would receive if he/she elects to begin receiving retirement benefits at his/her normal retirement age.” SSA’s PIA explanation describes the formula.
The overall sequence is: wage-index eligible earnings, select the computation years, calculate AIME, apply the PIA formula for the relevant eligibility year, and adjust for the selected claiming age and applicable COLAs. The formula’s bend points are tied to the year a person first becomes eligible—typically the year they reach 62 for retirement benefits—not simply the year they apply.

How do my highest 35 years affect my Social Security benefit?
SSA generally uses up to 35 years of wage-indexed earnings in the standard retired-worker computation. It selects the highest years, rather than necessarily using the last 35 years or the years immediately before retirement. A year with higher indexed earnings can replace a lower year in the calculation when it enters the top 35.
If you have fewer than 35 years with earnings, the calculation includes years without earnings to reach 35 years. Those zero-earning years can pull down the average. As a result, another year of covered earnings may raise AIME if it replaces a zero or a lower-earning year among the selected years. The size of any change depends on the earnings record and the formula; simply working one more year does not guarantee a specific increase.
The 35-year rule is a computation method, not a requirement that you work exactly 35 years before you can claim. It means SSA uses a 35-year span in the standard calculation, filling any shortfall in years with earnings with years without earnings. If you have more than 35 years, SSA generally selects the highest indexed earnings years rather than automatically including every year.
Wage indexing is not the same as a COLA
For earnings before age 60, SSA applies wage-index factors so earlier earnings are comparable with later wage levels. Earnings in the year you turn 60 and after are not wage-indexed in the same way. This is a step in constructing the earnings measure used by the formula.
COLAs are different: they apply to benefits under SSA’s schedule and rounding rules. Do not treat wage indexing as an annual increase to a worker’s benefit, or assume that the 2026 bend points are applied to everyone’s record. SSA explains the earnings and benefit calculation at Social Security Benefit Amounts.
What is AIME, and how does it affect my benefit?
AIME converts the selected earnings years into an average monthly earnings figure. SSA adds the selected indexed earnings, divides the total by 420 months (35 years multiplied by 12 months), and rounds down to the next lower dollar. If there are fewer than 35 years of earnings, years without earnings are part of the computation.
SSA then applies a three-part formula to AIME. Each percentage applies only to the portion of AIME in its bracket; the percentages are not applied to the entire AIME as competing alternatives. This progressive structure gives the first portion of AIME a higher replacement percentage than amounts in the higher brackets. The result is the PIA, not the AIME and not necessarily the amount ultimately paid each month.

For example, when AIME reaches more than one bracket, the calculation is cumulative: SSA calculates the first bracket’s share, adds the share for the amount in the next bracket, and, if applicable, adds the share for the amount above the second bend point. The bend points mark where the percentage applied to the next dollar changes; they are not caps on the amount of AIME or benefit.
What are the 2026 Social Security bend points?
For workers first eligible in 2026, the PIA formula uses bend points of $1,286 and $7,749. SSA applies the following percentages to the portions of AIME in each bracket:
| Portion of AIME | Formula percentage |
|---|---|
| First $1,286 | 90% |
| Above $1,286 through $7,749 | 32% |
| Above $7,749 | 15% |
In formula form, for a person first eligible in 2026: PIA = 90% of the first $1,286 of AIME, plus 32% of the portion from $1,286 through $7,749, plus 15% of any AIME above $7,749. The bend points are annual formula values, not universal thresholds for every current or future retiree. People first eligible in other years use the bend points applicable to their eligibility year. The SSA’s Primary Insurance Amount page provides the official formula details.
How to interpret the formula
Suppose a worker’s AIME is above the first bend point but below the second. The formula still applies 90% to the first $1,286 and applies 32% only to the amount above $1,286. If AIME exceeds $7,749, only the portion above that second bend point receives the 15% rate. This bracket-by-bracket method is why multiplying total AIME by one percentage will not reproduce the PIA.
The year matters as much as the bracket. The 2026 thresholds belong to workers first eligible in that year; they should not be used as a shortcut to calculate a worker whose eligibility year is different. In retirement cases, first eligibility is typically associated with age 62, so a person who applies later does not necessarily use the bend points for the year of application.
How much does claiming Social Security early reduce my benefit?
Claiming before FRA reduces the monthly amount relative to the FRA baseline. Waiting beyond FRA can increase it through delayed retirement credits. The precise result depends on the person’s FRA and claiming month; the age adjustment is not a separate calculation of AIME or a change to the historical earnings record.
For people born in 1943 or later, delayed retirement credits accrue at 8% per year and stop accruing at age 70. The credit rate and stopping age are described in SSA’s 2025 Annual Statistical Supplement, Appendix C. An 8% annual credit should not be read as a promise that waiting is best for every person: it describes the benefit adjustment, not a household-specific lifetime outcome.
The research supports a specific illustration of an early-claiming reduction, not one universal reduction percentage for every birth year and claiming month. For an accurate comparison, use the FRA and start dates attached to your personalized SSA estimate. A percentage from one example should not be transplanted to another person’s calculation.

SSA’s 2026 benefit-calculation examples show how the age adjustment changes the amount. These are official illustrations, not forecasts for a reader with different earnings or dates.
| Illustrative worker | PIA and FRA | Illustrated monthly benefit |
|---|---|---|
| Born in 1964; claims at 62 | 2026 PIA of $2,609.80; FRA 67 | $1,826, reflecting a 30% early reduction and rounding |
| Born in 1959; claims at FRA | PIA of $4,152.40; FRA 66 years and 10 months | $4,152 at FRA after rounding |
These cases illustrate why a quoted PIA and a quoted payment are not interchangeable. SSA’s 2026 worker benefit examples show the calculation examples.
How should I compare claiming ages?
There is no single claiming age that is best for every household. A later start can mean a higher monthly benefit, but also means giving up months of payments while waiting. To compare options, consider:
- Monthly amount: Compare personalized estimates at plausible start dates rather than applying a generic percentage to an assumed benefit.
- Months of benefits forgone: Waiting delays the beginning of payments; that matters alongside the higher amount available later.
- Health and work plans: Expected longevity, employment, and when income is needed affect the practical choice.
- Household needs: A spouse’s circumstances and potential survivor needs can make a decision more than an individual break-even calculation.
The SSA calculation rules establish how claiming age adjusts an amount, but they do not determine which choice maximizes lifetime benefits for a particular household. Use the adjustment as one input to a decision, not as a universal recommendation.

The general formula cannot produce a reliable personal estimate without your covered earnings record, birth date, and planned benefit start date. Check the earnings history SSA has recorded for you and use its personalized estimate rather than extrapolating from an example.
- Review your earnings record: Sign in to your SSA account and check the recorded earnings history for missing or incorrect years.
- Compare personalized estimates: Use SSA’s retirement estimator or benefit information to view estimates for different starting ages available for your record.
- Check assumptions: Make sure you understand what future earnings, if any, the estimate assumes and compare dates on the same basis.
- Revisit the estimate when circumstances change: Earnings and a revised claiming plan can change the estimate; use your SSA record rather than a formula example as your personal baseline.
SSA’s official benefit amount explanation outlines how earnings records feed the calculation. SSA’s 2026 retirement benefit calculation examples provide additional illustrations, but neither substitutes for your individualized record.
Before comparing estimates, confirm that you are looking at the same kind of figure: AIME, PIA, and the estimated monthly amount are different stages. A formula explanation can help you understand why estimates differ, but it cannot replace checking that the earnings record itself is complete and accurate.
Common calculation mistakes to avoid
- Calling AIME the monthly check: AIME is an earnings average; SSA uses it to calculate PIA, which is then subject to claiming-age and other applicable adjustments.
- Using 2026 bend points for every retiree: The bend points depend on the year of first eligibility, typically age 62 for retirement cases.
- Assuming fewer than 35 working years are ignored: Years without earnings are included when the worker has fewer than 35 years of earnings.
- Treating an SSA example as a personal quote: The examples reflect specific birth dates, PIAs, and claiming ages; your earnings record and timing may differ.
- Mixing up wage indexing and COLAs: Wage indexing adjusts eligible past earnings in the calculation, while COLAs affect benefits under their own schedule and rounding rules.
- Assuming a later start guarantees a better household outcome: Delayed credits can increase the monthly amount, but waiting also means forgoing payments, and household circumstances matter.
Frequently Asked Questions
Is AIME the amount Social Security pays each month?
No. AIME is the monthly average derived from selected wage-indexed earnings. SSA applies the PIA formula to AIME, then adjusts the PIA for claiming age and applicable COLAs and rounding rules to determine the payable amount.

SSA includes years without earnings to complete the 35-year computation. Those years can lower the average, while an additional covered-earnings year may raise AIME if it replaces a zero or a lower-earning year in the top 35.
Do the 2026 bend points apply to everyone who retires in 2026?
No. The $1,286 and $7,749 bend points apply to workers first eligible in 2026. Bend points depend on the first-eligibility year, typically the year a person reaches 62 for retirement benefits, not simply the year they apply.
How much will my own Social Security benefit be?
The general formula alone cannot determine an individual estimate. It depends on your covered earnings record, birth date, and benefit start date. Review your earnings record and personalized estimates through SSA rather than using an illustrative example as a forecast.
Does waiting until age 70 always mean I get the most from Social Security?
Waiting past FRA can increase the monthly benefit through delayed retirement credits; for people born in 1943 or later, credits accrue at 8% per year and stop at 70. That adjustment alone does not establish the best choice for every household because waiting also means giving up months of payments and health, work, and family circumstances differ.

The Bottom Line
Social Security calculates retirement benefits by wage-indexing eligible earnings, using the highest 35 years to determine AIME, and applying the PIA formula for the worker’s first-eligibility year. Claiming age and applicable COLAs then affect the amount paid. The 2026 bend points are $1,286 and $7,749 only for workers first eligible in 2026. For a personal estimate, check your SSA earnings record and compare the agency’s estimates for your birth date and possible start dates.
