Your benefit amount depends on your earnings history and when you claim

Social Security calculates your monthly payment based on how much you earned during your working years, not on how much you paid into the system. The Social Security Administration (SSA) looks at your 35 highest-earning years, adjusts them for inflation, and uses that average to set your benefit. If you worked fewer than 35 years, they count zeros for the missing years, which lowers your total.

The age you claim also changes your payment. If you claim at your full retirement age (between 66 and 67 for most people now), you get your full benefit amount. Claiming earlier — as young as 62 — means a smaller monthly check for life. Claiming later — up to age 70 — means a larger monthly check for life. The difference between claiming at 62 and 70 can be 70 percent or more.

No two people's benefits are the same because no two earnings histories are the same. The SSA publishes national averages (around $1,800 per month for retired workers in 2024, though this changes yearly), but your actual amount depends entirely on what you earned.

Key Takeaways

  • Your benefit is based on your 35 highest-earning years, adjusted for inflation, so gaps in work history lower your payment.
  • Claiming at 62 gives you a smaller monthly amount than claiming at your full retirement age, and the reduction is permanent.
  • Claiming after your full retirement age increases your monthly payment by roughly 8 percent per year until age 70.
  • You can see your estimated benefit amount by creating an account on ssa.gov and viewing your Social Security Statement.
  • If you were married, divorced, or widowed, you may be may have access to to benefits based on someone else's earnings record in addition to or instead of your own.

How the SSA calculates your primary insurance amount

The SSA uses a three-step process. First, they take your 35 highest-earning years (adjusted for inflation to today's dollars) and divide by 420 months to get your average indexed monthly earnings. Second, they explore a formula that gives you a higher percentage of your first dollars earned and a lower percentage of your higher earnings — this is why lower-income workers get a larger percentage of their lifetime earnings back. Third, they adjust the result for the age you claim.

This formula is fixed by law and does not change based on how much money is in the Social Security trust fund or how many people are drawing benefits. Your calculation is mechanical: the SSA plugs your numbers in, and the formula produces your amount.

If you worked for a government employer (federal, state, or local) and did not pay Social Security taxes, the SSA may reduce your benefit under the Government Pension Offset or Windfall Elimination Provision. These rules are complex and affect only people with government pensions, but they can lower your payment significantly. If you have a government pension, ask the SSA directly whether one of these rules applies to you.

What claiming age means for your monthly payment

Your "full retirement age" is when you can claim your full benefit without any reduction. For people born between 1943 and 1954, that age is 66. For people born between 1955 and 1960, it rises gradually to 67. For people born in 1960 or later, it is 67. The SSA website has a table showing the exact age for your birth year.

If you claim before your full retirement age, your payment is reduced. Claiming at 62 (the earliest allowed age) typically means a 30 percent reduction if your full retirement age is 67. Claiming at 63 means roughly a 25 percent reduction. The reduction gets smaller the closer you are to your full retirement age. These reductions are permanent — even after you reach your full retirement age, your payment stays at the reduced amount.

If you claim after your full retirement age, your payment increases. For each year you wait past your full retirement age, your benefit grows by about 8 percent per year. At age 70, you reach the maximum benefit — waiting past 70 does not increase it further. For someone with a full retirement age of 67, the difference between claiming at 62 and claiming at 70 is roughly 76 percent more per month at 70.

How to find your estimated benefit before you claim

The fastest way is to create a my Social Security account at ssa.gov. You will need your Social Security number, email address, and a way to verify your identity (usually a phone number or state ID). Once you are logged in, you can view your Social Security Statement, which shows your estimated benefit at age 62, your full retirement age, and age 70. The estimate assumes you keep earning at your current rate until you claim.

If you do not want to create an online account, you can call the SSA at 1-800-772-1213 (Monday through Friday, 7 a.m. to 7 p.m. your local time) and ask for a benefit estimate. You will need your Social Security number, date of birth, and mother's maiden name. The SSA can mail you a statement, though this takes longer than checking online.

The estimate you see is not a promise — it is based on current law and your current earnings record. If you earn more in the coming years, your benefit will be higher. If you have errors on your record (a missing year of earnings, a wrong name, a duplicate Social Security number), your benefit may be lower than it should be. Review your statement for gaps or errors and contact the SSA to correct them before you claim.

Benefits based on someone else's earnings record

If you were married for at least 10 years and are now divorced, you may be may have access to to a benefit based on your ex-spouse's earnings record. This benefit can be up to 50 percent of what your ex-spouse gets at their full retirement age, and you do not need your ex-spouse's permission to claim it. You must be at least 62 and your ex-spouse must be at least 62 (or deceased).

If you are widowed, you can claim a benefit based on your deceased spouse's earnings record at any age if you are caring for their child under 16, or at age 60 if you are not. The widow or widower benefit at full retirement age is typically 100 percent of what the deceased spouse was receiving (or would have received). Claiming before your full retirement age reduces this amount.

If you are currently married, you may be may have access to to a spousal benefit of up to 50 percent of your spouse's full retirement age benefit, but only if your spouse has already claimed. You cannot claim a spousal benefit on a spouse's record before your own full retirement age unless you are caring for a child under 16.

Why your benefit might be different from the national average

The national average benefit is useful for budgeting but tells you nothing about your own payment. Someone who worked 40 years in a high-wage job will receive far more than someone who worked 20 years in a low-wage job, even if they both claim at the same age. Someone who took time out of the workforce to raise children will receive less than someone with no gaps, because the SSA counts zeros for those years.

Your benefit is also affected by when you were born. People born in different years have different full retirement ages, which changes the reduction for claiming early or the increase for claiming late. A person born in 1955 has a different full retirement age than a person born in 1960, so their claiming decisions produce different results.

Cost of living adjustments (COLAs) happen once per year, usually in October, and affect everyone's benefit equally in percentage terms. If the COLA is 3 percent, everyone's benefit goes up 3 percent. This means the national average changes every year, but your own benefit changes by the same percentage as everyone else's.

What to do if your estimate seems wrong

If your Social Security Statement shows a year with zero earnings when you know you worked, or if it shows lower earnings than you remember, contact the SSA before you claim. Errors on your record are common — a name change, a missing W-2, or a typo in your Social Security number can cause earnings to be credited to the wrong account.

Bring your tax returns or W-2s from the years in question. The SSA can correct your record if you provide proof that you earned more than what is showing. Correcting errors now means a higher benefit for life, so it is worth the effort. If you are already claiming, you can still ask the SSA to correct your record, though the rules for adjusting your payment are stricter.

Frequently Asked Questions

Can I see my exact benefit amount before I claim?

No. The SSA provides an estimate based on your current earnings record and the assumption that you keep earning at your current rate. Your actual benefit will be slightly different if your earnings change before you claim. The estimate is accurate enough for planning, but the exact amount is set when you claim.

Does working longer increase my Social Security benefit?

Yes, if your recent earnings are higher than some of your earlier years. The SSA uses your 35 highest-earning years, so if you work longer and earn more, a higher-earning year replaces a lower-earning year in the calculation. If you are earning less than you did earlier in your career, working longer may not increase your benefit.

What happens to my benefit if I claim early and then change my mind?

You can withdraw your claim within 12 months of claiming and repay all the benefits you received. After 12 months, you cannot withdraw. If you claim at 62 and later regret it, you cannot undo the reduction — your benefit stays reduced for life. This is why the decision to claim early is important.

Do taxes reduce my Social Security benefit?

No. Your benefit is calculated before taxes. However, if your total income is above a certain threshold, up to 85 percent of your Social Security benefit may be subject to federal income tax. State taxes vary. Your benefit amount itself is not reduced, but you may owe taxes on it.

If I am married, do we each get our own benefit?

Yes. Each spouse has their own earnings record and their own benefit. You can also claim a spousal benefit based on your spouse's record if it is larger than your own, but you cannot claim both at full value — the SSA reduces the spousal portion. The rules are complex and depend on your ages and when you claim.
