Your Social Security payment depends on your earnings history and the age you claim
Social Security calculates your benefit based on how much you earned during your working years and when you start taking payments. The Social Security Administration (SSA) uses your highest 35 years of earnings to figure out a base amount called your Primary Insurance Amount (PIA). If you claim at your full retirement age — which ranges from 66 to 67 depending on your birth year — you receive 100 percent of that amount. If you claim earlier, your payment is smaller. If you claim later, your payment is larger.
You cannot know your exact benefit until you actually claim, because future earnings, cost-of-living adjustments, and changes to your work history can shift the number. But the SSA provides tools to estimate what you might receive based on your current record.
Key Takeaways
- Your benefit amount is based on your 35 highest-earning years, so gaps in work history or lower early-career earnings reduce your payment.
- Claiming at 62 gives you roughly 70 percent of your full retirement age benefit; claiming at 70 gives you roughly 124 percent.
- You can see your actual earnings record and a benefit estimate by creating an account on ssa.gov, which takes about 10 minutes.
- Cost-of-living adjustments happen each year, so your estimate will change slightly even if you do not work again.
- If you were married, divorced, or widowed, you may have other benefit options that change the calculation.
How the SSA calculates your base benefit amount
The SSA starts with your earnings record — the wages you reported to the IRS each year you worked. They take your highest 35 years of earnings, adjust each year's pay for inflation to today's dollars, and then average them across 35 years. This average becomes the basis for your Primary Insurance Amount.
If you worked fewer than 35 years, the SSA counts the missing years as zeros, which lowers your average and your benefit. Someone who worked 30 years will have a lower benefit than someone who worked 35 years with identical annual earnings, because five zero years drag down the average.
The SSA does not use a straightforward percentage of your average earnings. Instead, they explore a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings. This means the benefit formula is progressive — it replaces a larger share of income for people who earned less.
How your claiming age changes your monthly payment
Your full retirement age is the age at which you receive 100 percent of your calculated benefit. For people born between 1943 and 1954, full retirement age is 66. For people born between 1955 and 1960, it rises gradually from 66 and 2 months to 66 and 10 months. For people born in 1960 or later, full retirement age is 67.
If you claim at 62 — the earliest age you can claim — your benefit is roughly 70 percent of your full retirement age amount. For each year you delay past 62, your benefit increases by about 6 to 7 percent per year until age 70. If you wait until 70, your benefit is roughly 124 percent of your full retirement age amount. After 70, your benefit does not increase further, so there is no financial advantage to waiting past 70.
This means two people with identical earnings histories can receive very different monthly payments depending on when they claim. Someone who claims at 62 might receive $1,500 per month, while someone who waits until 70 might receive $2,100 per month — a difference of $600 per month for life.
Where to find your earnings record and estimate
The most accurate way to see what you might receive is to check your own record on the SSA website. Go to ssa.gov and create a my Social Security account. You will need your Social Security number, email address, and a way to verify your identity — usually a driver's license or passport number.
Once your account is set up, you can view your complete earnings history as the SSA has it on file. This is important because errors happen — a wage reported under the wrong name or number, or a year of earnings that did not get recorded. If you spot a mistake, you can file a correction with the SSA, though you will need documents like old tax returns or W-2s to prove the error.
Your account also shows an estimate of your benefit at three claiming ages: 62, your full retirement age, and 70. The estimate assumes you will not work again and that cost-of-living adjustments continue at historical rates. The SSA updates this estimate once per year.
Why your estimate might change
If you continue to work, your benefit estimate will change. The SSA recalculates your benefit each year based on your most recent earnings. If you earn more in a recent year than in one of your 35 highest-earning years, that recent year replaces the lower year, raising your average and your benefit.
Cost-of-living adjustments (COLA) also change your estimate. Each year in October, the SSA announces a COLA percentage based on inflation. This adjustment applies to all current beneficiaries and is factored into estimates for future beneficiaries. A year with high inflation produces a larger COLA; a year with low inflation produces a smaller one.
Changes to Social Security law could also affect your benefit, though this is rare. Congress would have to pass new legislation, which has not happened since 1983.
How marriage, divorce, and widowhood affect your benefit
If you were married for at least 10 years and are now divorced, you may be able to claim a benefit based on your ex-spouse's earnings record instead of your own — if that benefit is higher. You do not need your ex-spouse's permission, and claiming on their record does not reduce their benefit. You must be at least 62 and unmarried to claim this way.
If you are still married, you may be able to claim a spousal benefit — up to 50 percent of your spouse's full retirement age benefit — if you have reached full retirement age. If you claim a spousal benefit before full retirement age, the percentage is lower.
If your spouse has died, you may be able to claim a survivor benefit as a widow or widower. The amount depends on your age when you claim and your spouse's earnings record. A widow or widower can claim as early as 60 (or 50 if disabled), and the benefit can be as high as 100 percent of what your spouse was receiving or would have received.
What your estimate does and does not tell you
Your estimate shows you a monthly dollar amount based on the information the SSA has today. It assumes you will live to an average age and that inflation continues at historical rates. It does not account for major life changes — a period of disability, a return to work, or a significant drop in income.
The estimate also does not include any taxes you may owe on your benefits. Depending on your other income, between 0 and 85 percent of your Social Security benefit may be subject to federal income tax. Some states also tax Social Security benefits. Your estimate is the gross benefit before taxes.
Finally, the estimate is not a promise. The SSA can only may provide your benefit once you actually claim. Until then, the estimate is based on current law and current records, both of which can change.
Frequently Asked Questions
How do I know if there are errors in my earnings record?
Log into your my Social Security account and look at the year-by-year earnings history. Compare it to your old W-2s or tax returns. If you see a year with no earnings when you know you worked, or earnings that seem too low, contact the SSA. You have a limited time to correct errors — generally three years, three months, and 15 days after the year in which you earned the wages.
Can I get a higher benefit if I work longer?
Yes, if your recent earnings are higher than some of your 35 highest-earning years. Each year you work, the SSA recalculates your benefit by replacing your lowest-earning year with your most recent year. If you earned very little early in your career, working longer can meaningfully increase your benefit.
What happens to my benefit if I claim early and then change my mind?
If you claim before full retirement age and then want to stop, you have limited options. You can withdraw your claim within 12 months of claiming and repay all benefits you received, which resets your record. After 12 months, you cannot withdraw. You can suspend your benefits at full retirement age or later, which pauses payments and lets your benefit grow, but this is different from withdrawing.
Does my benefit estimate include Medicare premiums?
No. Your estimate is your gross Social Security benefit. Medicare Part B and Part D premiums are deducted from your benefit check, but the estimate does not show this. You will see the actual amount deposited to your account once you claim and enroll in Medicare.
Will my estimate change if I move to another country?
Your benefit amount does not change based on where you live. However, some countries have agreements with the United States about Social Security, and some do not. If you move abroad, contact the SSA to confirm you can still receive your benefit and how payments will be sent to you.
