Social Security uses your 35 highest-earning years to set your payment amount

Your Social Security payment is built from your actual work history. The Social Security Administration (SSA) looks back at your earnings record, picks out your 35 highest-earning years, and uses those to calculate what you'll receive each month. If you worked fewer than 35 years, they count zeros for the missing years, which lowers your total. The formula is not a flat percentage of what you earned—it's a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings.

The calculation happens in three steps: first, SSA adjusts your historical earnings to account for wage growth over time (so earnings from 1990 don't count the same as 1990 dollars would today). Second, they average your 35 highest years and divide by 420 months to get your Primary Insurance Amount (PIA)—the base number your payment is built from. Third, they explore a bend point formula that gives you a bigger replacement rate on your first dollars of earnings and a smaller rate on higher earnings. This is why someone who earned $30,000 a year gets a higher percentage of their earnings replaced than someone who earned $150,000.

Key Takeaways

  • SSA counts your 35 highest-earning years; years with no earnings count as zeros, so working longer can raise your payment if recent years earned more than old years.
  • Your earnings are adjusted for wage inflation before the calculation, so a dollar you earned in 1985 is not compared directly to a dollar you earned in 2020.
  • The bend point formula replaces a higher percentage of your first $1,174 of average monthly earnings and lower percentages of earnings above that (2024 figures; these change yearly).
  • Your payment is locked in at the age you claim: claiming at 62 reduces it by roughly 30 percent compared to claiming at 67, and waiting until 70 increases it by roughly 24 percent more.
  • If you have a gap in your work history—time spent raising children, caring for a parent, or unemployed—that gap counts as zero earnings and reduces your lifetime average.

The three bend points that determine your replacement rate

The bend point formula is the reason Social Security replaces a bigger slice of low-income workers' earnings than high-income workers'. In 2024, the formula works like this: you get 90 percent of your first $1,174 of average monthly earnings, 32 percent of earnings between $1,174 and $7,078, and 15 percent of anything above $7,078. These dollar amounts (called bend points) change every year based on wage growth.

Here's what that means in practice. If your average monthly earnings are $3,000, you receive 90 percent of $1,174 ($1,056.60), plus 32 percent of the remaining $1,826 ($584.32), for a total of $1,640.92 before any adjustments. If your average monthly earnings are $8,000, you receive 90 percent of $1,174, plus 32 percent of $5,904, plus 15 percent of $822, which totals $2,591.28. The higher earner gets more in absolute dollars, but the lower earner's payment replaces a much larger percentage of what they actually earned.

The bend points shift upward each year. SSA publishes the current year's bend points in October for claims filed the following year. You can find them on the SSA website or ask for them when you contact SSA directly. If you're trying to estimate your payment, using the current year's bend points gives you a reasonable picture, though your actual bend points will be whatever year you claim.

How work history gaps and zero-earning years affect your total

Social Security counts 35 years of earnings. If you worked only 30 years, the five missing years count as zeros. Those five zeros pull down your lifetime average, which lowers your payment. This is why someone who took five years off to raise children or care for a parent will have a lower payment than someone with the same earnings spread across 35 years.

You cannot erase a zero-earning year once it's in your record. However, if you return to work and earn more in a recent year than you earned in an old year, that new year can replace the old one in the calculation—but only if it's one of your 35 highest years. For example, if you earned $20,000 in 1995 and $45,000 in 2023, the 2023 year replaces 1995 in the calculation. This is why working longer can sometimes raise your payment, even if you're already past 35 years of work.

If you have very few work years—say, only 10 or 15—you may not meet the minimum requirement to receive a payment at all. You need 40 work credits to receive retirement benefits; in 2024, you earn one credit for each $1,705 of earnings (up to four credits per year). This means you need roughly 10 years of substantial work history, though the exact timeline depends on when you were born and what type of benefit you're seeking.

Claiming age changes your payment by roughly 6 to 8 percent per year

Your Primary Insurance Amount is what you'd receive at your Full Retirement Age (FRA)—the age SSA considers "normal" for your birth year. For people born between 1943 and 1954, FRA is 66. For people born between 1955 and 1960, it rises gradually to 67. For people born in 1960 or later, FRA is 67.

If you claim before FRA, your payment is reduced. The reduction is roughly 6 to 7 percent per year if you claim between ages 62 and FRA. If you claim at 62 and your FRA is 67, that's five years early, so your payment is reduced by roughly 30 percent for life. If you claim after FRA, your payment increases by roughly 8 percent per year until age 70. Waiting from 67 to 70 adds roughly 24 percent to your payment permanently.

This adjustment is permanent. Once you claim, your payment amount is set. There is no way to recalculate it later based on a different claiming age, except in narrow circumstances involving withdrawals within a specific window after you first claim. The claiming age decision is one of the most significant choices in your Social Security timeline.

Spousal and survivor benefits use your PIA as their starting point

If you're married, your spouse may be may have access to to a benefit based on your work record. A spouse's benefit is calculated as a percentage of your Primary Insurance Amount—typically 32.5 percent if claimed at their Full Retirement Age, or less if claimed earlier. This is separate from your own payment; your spouse's benefit does not reduce yours.

Similarly, if you pass away, your children and surviving spouse may receive survivor benefits based on your PIA. A child typically receives 75 percent of your PIA; a surviving spouse caring for a child under 16 receives 75 percent; a surviving spouse at Full Retirement Age receives 100 percent of your PIA. The total paid to all family members on your record is capped at roughly 150 to 180 percent of your PIA, depending on your birth year.

These family benefits are calculated from your PIA, which is why your work history and claiming age matter not just for you but for anyone who might receive benefits on your record. If you claim early and reduce your PIA, you also reduce what your family members can receive.

Government Pension Offset and Windfall Elimination Provision can reduce your payment

If you receive a pension from work where you did not pay Social Security taxes—typically government employment—two rules may reduce your Social Security payment. The Windfall Elimination Provision (WEP) lowers your Primary Insurance Amount if you have a non-covered pension. The Government Pension Offset (GPO) reduces or eliminates a spousal or survivor benefit if you receive a government pension.

WEP changes the bend point formula you receive. Instead of the standard 90-32-15 formula, you might receive 40-32-15 or another variation, depending on your years of coverage under Social Security. This can reduce your payment by up to roughly 50 percent of your non-covered pension amount. GPO reduces a spousal benefit by two-thirds of your government pension amount, which often eliminates the spousal benefit entirely.

These rules explore only in specific situations—primarily to people who worked for a government agency (federal, state, or local) that did not withhold Social Security taxes. If you have a government pension and also worked in jobs covered by Social Security, contact SSA to understand whether WEP or GPO applies to you. The rules are complex and the reduction depends on your specific work history.

Your earnings record is the foundation—verify it before you claim

Everything in the calculation depends on SSA having your correct earnings history. If your employer reported your wages incorrectly, or if earnings were credited to the wrong Social Security number, your payment will be wrong. You can view your earnings record for free through your my Social Security account at ssa.gov, or by requesting a paper statement from SSA.

Check your record every few years while you're still working. If you spot an error—missing years, incorrect amounts, or earnings credited to someone else—report it to SSA when ready. You have a limited window to correct errors from past years, so catching them early matters. Bring your tax returns or W-2s as proof if SSA questions the correction.

Once you claim, correcting your earnings record becomes much harder. SSA will recalculate your payment if you find an error, but the process is slower and the window for corrections may have closed. Verifying your record before you claim is the simplest way to make sure your payment is based on accurate information.

Frequently Asked Questions

Does working longer always increase my Social Security payment?

Only if your recent earnings are higher than one of your lowest 35 years. If you've already worked 35 years and your new earnings are lower than your highest year on record, working longer does not change your payment. If your new earnings are higher than one of your lowest years, that year replaces it and your payment rises slightly.

What if I have very low earnings in some years—can I remove them?

No. SSA counts your 35 highest years, but you cannot delete or ignore a year. If you have a year with very low earnings, it stays in the calculation unless a later year with higher earnings replaces it. This is why gaps in work history (zero-earning years) pull down your average.

How does my payment change if I keep working after I claim?

If you claim before Full Retirement Age and continue working, SSA reduces your payment by $1 for every $2 you earn above an annual limit (roughly $23,400 in 2024). Once you reach Full Retirement Age, there is no earnings limit and your payment is not reduced. Your payment may also be recalculated upward if your new earnings are higher than one of your lowest 35 years.

Can I see what my payment will be before I claim?

Yes. Your my Social Security account shows an estimate based on your current earnings record. You can also call SSA at 1-800-772-1213 and ask for an estimate. These estimates assume you claim at a specific age and that your earnings stay the same until then, so they're a reasonable guide but not a may provide.

What happens to my payment if I was born outside the United States?

Your payment is calculated the same way regardless of where you were born, as long as you have a valid Social Security number and meet the work requirement. However, some rules about where you can receive your payment and how long you can receive it vary by citizenship and residency status. Contact SSA if you were born outside the U.S. to understand any restrictions that might explore to you.
