Your Social Security payment depends on how much you earned during your working years and when you claim

Social Security calculates your monthly payment based on your Primary Insurance Amount (PIA), which is tied to your earnings record. The Social Security Administration (SSA) looks at your 35 highest-earning years, adjusts them for inflation, and uses a formula to arrive at a number. If you claim at your full retirement age (66 to 67 for most people now), you get 100% of that amount. If you claim earlier, at 62, your payment is permanently reduced — typically by about 30%. If you delay past full retirement age, your payment grows by roughly 8% per year until age 70.

The actual dollar amount varies widely. Someone who earned the federal minimum wage most of their life will receive a smaller payment than someone who earned six figures. A person with gaps in their work history — years with zero earnings — will see a lower PIA than someone with continuous employment. And the year you were born affects your full retirement age, which changes the math.

You cannot know your exact payment without looking at your own earnings record. The SSA does not publish a single number that applies to everyone.

Key Takeaways

  • Your payment is calculated from your 35 highest-earning years, so gaps in work history lower your benefit.
  • Claiming at 62 reduces your payment by roughly 30% compared to claiming at full retirement age; claiming at 70 increases it by roughly 24% more than full retirement age.
  • You can view your estimated payment on your personal Social Security account at ssa.gov, which updates each year.
  • Married people may be may have access to to spousal benefits based on their partner's earnings record, which changes the calculation.
  • Your payment amount does not change after you start receiving it, except for annual cost-of-living adjustments (COLA).

How the Social Security Administration calculates your benefit

The SSA starts by looking at your W-2 forms and self-employment tax records going back to 1951 (or when you started working, whichever is later). They identify your 35 highest-earning years. If you worked fewer than 35 years, they count the missing years as zero, which lowers your average.

Next, they adjust each of those 35 years for inflation using a national wage index. This means a dollar you earned in 1990 is not compared directly to a dollar you earned in 2020; the older earnings are scaled up to reflect wage growth. The SSA then divides the total by 420 (the number of months in 35 years) to get your Average Indexed Monthly Earnings (AIME).

Finally, they apply a formula to your AIME. The formula uses bend points — dollar thresholds that change each year — to calculate your PIA. The formula is progressive: it replaces a higher percentage of lower earnings and a lower percentage of higher earnings. This is why someone earning $30,000 a year gets a higher replacement rate than someone earning $150,000 a year.

What claiming age means for your monthly payment

Your full retirement age is when you can claim 100% of your PIA. For people born in 1943 or later, this age ranges from 66 to 67, depending on your birth year. The SSA website lists your specific full retirement age based on your birth date.

If you claim at 62 (the earliest age), your payment is reduced by roughly 30%. If you claim at 70 (the latest age to delay), your payment is roughly 24% higher than your full retirement age amount. The exact percentages depend on your birth year, but the direction is always the same: earlier claiming means a smaller monthly check; later claiming means a larger one.

This is a permanent choice. Once you start receiving benefits, the reduction or increase is locked in for life. You cannot change your mind later and get a bigger payment (with limited exceptions for people who claim before age 70 and then change their minds within 12 months).

Viewing your estimated payment before you claim

The most accurate way to see what you might receive 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 bank account). Once logged in, you can view your earnings record and see an estimate of your payment at different claiming ages.

This estimate is based on the assumption that your earnings remain the same until you claim. If you plan to work longer, your estimate may be conservative. If you plan to retire early and have no more earnings, your estimate will be accurate.

You can also call the SSA at 1-800-772-1213 to request a statement by mail, though this takes longer than checking online. The online account is updated each year after your tax return is processed.

How marriage and divorce affect your benefit

If you are married, you may be may have access to to a spousal benefit based on your spouse's earnings record. The spousal benefit is up to 50% of your spouse's PIA (if you claim at your full retirement age). You cannot receive more than the higher of your own benefit or the spousal benefit; you receive one or the other, not both.

If you are divorced and were married for at least 10 years, you may be may have access to to a benefit based on your ex-spouse's earnings record, even if they have not claimed yet. You do not need their permission, and claiming on their record does not reduce their payment. However, you must be at least 62 and unmarried.

If you are widowed, you may receive a survivor benefit based on your deceased spouse's earnings record. The amount depends on your age when you claim and whether you are caring for children under 16.

Cost-of-living adjustments and how your payment changes over time

Once you start receiving Social Security, your payment does not stay the same forever. Each year, the SSA applies a cost-of-living adjustment (COLA) to all benefits. The COLA is based on the Consumer Price Index and is announced in October for the following year. In recent years, COLA has ranged from 0% (in some years) to over 8% (in 2023).

This means your payment grows slightly each year, but only to keep pace with inflation — not to increase your purchasing power beyond what it was when you started claiming. If inflation is low, your COLA is low. If inflation is high, your COLA is higher.

Your payment does not change for any other reason. It does not go up if you return to work after claiming, and it does not go down if you have other income (though other income may affect your taxes on Social Security benefits).

What happens if you have a work history outside the United States

If you worked in another country and paid into that country's social security system, you may be may have access to to benefits from both systems. The SSA has totalization agreements with about 30 countries that allow you to combine work credits from both countries to meet the requirement for U.S. Social Security benefits.

However, the rules are complex and depend on which country you worked in, how long you worked there, and when you worked. If you have an international work history, contact the SSA directly or visit ssa.gov/international to learn whether you may be may have access to to benefits from another country.

Frequently Asked Questions

Can I see my Social Security payment estimate without creating an online account?

Yes. Call the SSA at 1-800-772-1213 and request a statement by mail. You can also visit your local Social Security office in person. The online account is faster, but the phone and in-person options work if you prefer not to create an account.

Will my Social Security payment be enough to live on?

That depends on your expenses and other income. Social Security is designed to replace about 40% of pre-retirement earnings for an average worker. Most financial advisors suggest you will need other sources of income — savings, pensions, part-time work — to maintain your standard of living in retirement.

What if I worked part-time most of my life?

Your benefit will be lower than someone who worked full-time at higher wages, because it is based on your 35 highest-earning years. Years with part-time or low earnings pull down your average. However, you still receive a benefit as long as you have at least 40 work credits (roughly 10 years of work).

Does my Social Security payment change if I keep working after I claim?

Your monthly payment amount does not change. However, if you claim before full retirement age and earn above a certain threshold (which changes each year), the SSA temporarily withholds some of your benefits. Once you reach full retirement age, this withholding stops and your payment increases to account for the months it was withheld.

How do I know if my earnings record is correct?

Log into your my Social Security account and review the earnings listed for each year. If you see an error — a year with no earnings when you worked, or earnings that seem too low — contact the SSA with your W-2 or tax return as proof. Errors can lower your benefit, so it is worth checking before you claim.
