Your payment depends on your earnings history and the age you start claiming

Social Security calculates your monthly payment using three pieces of information: how much you earned during your working years, how many years you worked, and what age you start taking benefits. The Social Security Administration (SSA) does not use a flat rate or a formula that treats everyone the same. Two people born in the same year with different work histories will receive different amounts.

The SSA looks back at your 35 highest-earning years and averages them. If you worked fewer than 35 years, they count zeros for the missing years, which lowers your average. Once they calculate that average, they apply a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings — this is why someone who earned $30,000 a year receives a larger percentage of their former income than someone who earned $150,000 a year.

Then your age at the time you claim matters enormously. If you claim at 62 (the earliest age), your payment is permanently reduced. If you wait until 70, your payment is permanently increased. The reduction or increase is not small — it can be 30 to 40 percent different between claiming at 62 versus 70.

Key Takeaways

  • The SSA uses your 35 highest-earning years to calculate your payment; years you did not work count as zero.
  • Claiming at 62 gives you a smaller monthly payment for life; claiming at 70 gives you a larger monthly payment for life.
  • You can see your estimated payment on your Social Security account at ssa.gov, which updates each year.
  • Your payment amount also depends on whether you are claiming as a retiree, a survivor, or a person with a disability — each category has its own calculation rules.

How the SSA calculates your Primary Insurance Amount

The SSA starts by taking your 35 highest-earning years and calculating your Average Indexed Monthly Earnings (AIME). This is your average monthly income across those years, adjusted for inflation. If you worked more than 35 years, they drop your lowest-earning years. If you worked fewer than 35 years, they use zeros for the missing years.

Once they have your AIME, they apply a bend point formula. This formula replaces 90 percent of your first $1,174 in monthly earnings (as of 2024), 32 percent of earnings between $1,174 and $7,078, and 15 percent of earnings above $7,078. These dollar amounts change each year. The result is your Primary Insurance Amount (PIA) — the payment you would receive if you claimed at your full retirement age.

The bend points are why lower earners receive a higher percentage of their former income. Someone who averaged $1,500 a month gets roughly 76 percent of that income replaced. Someone who averaged $6,000 a month gets roughly 42 percent replaced. This is intentional — Social Security is designed to replace a larger share of income for people who earned less.

How your age when you claim changes your payment

Your full retirement age depends on your birth year. For people born in 1960 or later, full retirement age is 67. If you were born between 1943 and 1954, it is 66. The SSA has a table on its website 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 age) reduces your payment by about 30 percent if your full retirement age is 67. The reduction is smaller if you claim closer to your full retirement age — claiming at 66 reduces it by about 13 percent.

If you delay claiming past your full retirement age, your payment increases by 8 percent for each year you wait, up to age 70. Waiting from 67 to 70 adds 24 percent to your payment. After age 70, your payment does not increase further, so there is no financial reason to delay past 70.

These adjustments are permanent. If you claim at 62, you receive the reduced amount for the rest of your life. If you wait until 70, you receive the increased amount for the rest of your life. The SSA does not recalculate based on how long you live.

What you can see in your Social Security account

You can create a free account at ssa.gov and view your estimated payment. The SSA shows you three estimates: what you would receive if you claimed at 62, at your full retirement age, and at 70. These estimates assume you continue working at your current earnings level until you claim.

Your account also shows your earnings record — the year-by-year income the SSA has on file for you. You should check this record for errors, because mistakes in your earnings history directly lower your payment. If you see a year where your employer did not report your income or reported it incorrectly, you can contact the SSA with documentation (like a W-2 or tax return) to request a correction.

The estimates update each year after you receive your Social Security statement. If your earnings change significantly — for example, if you get a raise or take a lower-paying job — your estimate will shift the next time it updates.

How work history affects your payment

The SSA requires you to have worked and paid Social Security taxes for at least 10 years (40 quarters) to receive a retirement benefit. If you have fewer than 10 years of work history, you do not receive a payment based on your own earnings.

If you have worked between 10 and 35 years, the missing years count as zeros in your calculation. This significantly lowers your average. Someone who worked 20 years and then stopped will have 15 years of zeros in their 35-year average, which cuts their payment roughly in half compared to someone with 35 years of earnings at the same level.

If you took time out of the workforce — for caregiving, unemployment, or other reasons — those years count as zeros unless you were receiving Social Security benefits for disability or survivor benefits during that time. Years on disability or as a survivor do not count as work years, but the SSA does not penalize you by counting them as zeros.

Payments for spouses, ex-spouses, and survivors

If you are married, your spouse may receive a payment based on your earnings record. A spouse at full retirement age receives up to 50 percent of your Primary Insurance Amount. A spouse who claims before full retirement age receives less. An ex-spouse can receive the same benefit if the marriage lasted at least 10 years and you are at least 62.

Survivors — your children and widow or widower — receive payments based on your earnings record if you die. The total amount paid to all family members cannot exceed about 150 to 180 percent of your Primary Insurance Amount, depending on how many survivors there are. Each survivor's individual payment is smaller if there are more family members receiving benefits.

If you receive disability benefits, your payment is calculated the same way as a retirement benefit, but you do not have to wait until 62 to claim. Once you reach full retirement age, your disability payment converts to a retirement payment at the same amount.

Why your estimate might change

Your estimated payment can shift for several reasons. If you continue working, your recent earnings may replace one of your lower-earning years in the 35-year average, raising your estimate. If you have a year of very low earnings or no earnings, that might enter your 35-year average and lower your estimate.

The bend point dollar amounts change each year based on national wage growth. This means the SSA recalculates everyone's Primary Insurance Amount annually, even if your earnings record does not change. Your estimate will reflect these adjustments.

Cost-of-living adjustments (COLA) happen each year and increase the payment amount for people already receiving benefits. These adjustments do not affect your estimate before you claim, but they do affect what you actually receive once you start.

Frequently Asked Questions

Can I see my exact payment amount before I claim?

No. The SSA provides an estimate based on your current earnings record and the assumption that you continue earning at your current level. Your actual payment depends on your exact earnings in the years between now and when you claim. You can see the estimate at ssa.gov, but the final amount is calculated when you actually claim.

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

If you claim before your full retirement age and continue working, the SSA reduces your payment by $1 for every $2 you earn above a certain limit (the limit changes each year). Once you reach full retirement age, there is no earnings limit and your payment does not reduce. After full retirement age, your payment may increase if your recent earnings replace a lower-earning year in your 35-year average.

What if I did not work 35 years?

The SSA counts zeros for the missing years, which lowers your average and your payment. If you worked 20 years, you have 15 zeros in the calculation. There is no way to remove those zeros, but you can add more work years if you return to the workforce before you claim.

How much more will I get if I wait until 70 instead of 62?

The difference depends on your Primary Insurance Amount, but the payment at 70 is roughly 76 percent higher than at 62. If your estimate at 62 is $2,000 a month, your estimate at 70 would be roughly $3,520 a month. This higher amount continues for life.

Do I need to do anything to lock in my payment amount?

No. Your payment is calculated when you claim, using your earnings record at that time. You do not need to take any action to protect or reserve your payment amount. When you are ready to claim, you contact the SSA and they calculate your final payment based on your complete earnings record and your age at that time.
