What determines your Social Security retirement payment

Your Social Security retirement payment is based on three things: your earnings history, the age you claim, and the year you were born. The Social Security Administration (SSA) looks at your 35 highest-earning years of work, adjusts them for inflation, and calculates an average. That average becomes the foundation of your payment amount. If you worked fewer than 35 years, they count zeros for the missing years, which lowers your average.

The age you claim changes your payment significantly. If you claim at your full retirement age (which ranges from 66 to 67 depending on birth year), you get your "primary insurance amount" — the full payment SSA calculated. If you claim earlier, your payment is permanently reduced. If you claim later, your payment increases by about 8 percent per year until age 70.

Your birth year also matters because it determines your full retirement age. Someone born in 1943 has a full retirement age of 66. Someone born in 1960 or later has a full retirement age of 67. SSA uses this age to calculate what your payment would be at that specific point.

Key Takeaways

  • SSA uses your 35 highest-earning years to calculate your payment, so years you did not work count as zeros and reduce your average.
  • Your full retirement age depends on your birth year and ranges from 66 to 67; claiming before that age permanently reduces your payment.
  • Claiming after your full retirement age increases your payment by roughly 8 percent per year until you reach age 70.
  • You can see your estimated payment on your Social Security account at ssa.gov, which shows what you would receive at different claim ages.
  • Your payment amount also affects your spouse's and children's benefits if they are may have access to to payments based on your work record.

How SSA calculates your earnings average

SSA starts by taking your 35 highest-earning years of covered work — years where you paid Social Security taxes. If you worked more than 35 years, they ignore your lowest-earning years. If you worked fewer than 35 years, they fill in zeros for the missing years.

Next, SSA adjusts each of those 35 years for inflation using a formula called wage indexing. This means a dollar you earned in 1990 is adjusted to reflect what that dollar would be worth in the year you turn 60. This adjustment ensures that workers who earned money decades ago are not penalized just because wages have risen overall.

After adjusting for inflation, SSA adds up all 35 years and divides by 420 (the number of months in 35 years) to get your average indexed monthly earnings, or AIME. This number is the raw foundation of your payment.

The bend points formula that determines your actual payment

SSA does not pay you your full AIME. Instead, they apply a formula with bend points — dollar thresholds that determine what percentage of your earnings you receive. The bend points change each year based on wage growth.

Here is how it works: on your first dollars of AIME (up to the first bend point), you receive 90 percent. On dollars between the first and second bend point, you receive 32 percent. On dollars above the second bend point, you receive 15 percent. This formula means lower-earning workers get a higher percentage of their earnings replaced, while higher-earning workers get a lower percentage.

For someone claiming in 2024, the first bend point is $1,174 and the second is $7,078. If your AIME is $3,000, you would receive (90% of $1,174) plus (32% of $1,826) plus (15% of $0) — which equals about $1,638 per month at your full retirement age. The exact bend points for your year of claim are on the SSA website.

How claiming age reduces or increases your payment

Your full retirement age is when you receive 100 percent of your calculated payment. Claiming before that age triggers a reduction factor that permanently lowers your payment. Claiming at 62 (the earliest age) reduces your payment by about 30 percent if your full retirement age is 67. Claiming at 63 reduces it by about 25 percent. Each month you wait before your full retirement age reduces the payment by roughly 0.55 percent.

Claiming after your full retirement age increases your payment through delayed retirement credits. For each year you wait past your full retirement age, your payment grows by 8 percent per year, or about 0.67 percent per month. This increase continues until you reach age 70. After 70, your payment does not increase further, so there is no financial reason to wait past that age.

The reduction or increase is permanent. If you claim at 62 and receive a reduced payment, that payment amount (adjusted for cost-of-living increases) stays with you for life. You cannot later decide to claim again at full retirement age and receive the higher amount.

Where to find your estimated payment amount

The easiest way to see what you might receive is to create a my Social Security account at ssa.gov. Once you log in, you can view your earnings record and see an estimate of your payment at different claim ages — typically at 62, your full retirement age, and 70. This estimate is based on your actual earnings history and is updated each year.

If you do not have an online account, you can request a paper statement by calling SSA at 1-800-772-1213 or visiting your local Social Security office. The paper statement also shows your estimated payments at different ages, though it may take a few weeks to arrive.

These estimates assume you continue working until you claim and that your earnings stay roughly the same. If you plan to work longer or expect a significant change in income, your actual payment may differ. SSA recalculates your payment each year based on your current earnings, so your estimate may go up if you have additional high-earning years.

How your payment affects family members' benefits

Your payment amount is not just about you. If you are married, your spouse may be may have access to to a payment based on your work record — up to 50 percent of your full retirement age payment if they claim at their own full retirement age. If you have children under 19 (or 19 if still in high school), they may also receive payments based on your record.

The total amount paid to your family members is capped at about 150 to 180 percent of your full retirement age payment, depending on your situation. This means if you have multiple family members receiving benefits on your record, each person's payment may be reduced proportionally so the total does not exceed the family maximum.

Your age when you claim affects your spouse's and children's payments too. If you claim early, your payment is reduced, which also reduces the maximum amount available to your family members. This is one reason some married couples coordinate their claiming strategy — one spouse may claim early while the other waits, to balance household income and maximize lifetime benefits.

Frequently Asked Questions

What if I did not work 35 years?

SSA counts zeros for each year under 35 that you did not have covered earnings. This lowers your average indexed monthly earnings and reduces your payment. However, you only need 40 credits (roughly 10 years of work) to be may have access to to retirement benefits at all. If you have fewer than 40 credits, you cannot receive retirement payments on your own record.

Can I see how my payment would change if I worked longer?

Your my Social Security account shows your current estimate based on your earnings through last year. If you continue working, SSA will recalculate your payment each year, replacing one of your lower-earning years with your new year's earnings if it is higher. You can contact SSA directly to ask about a rough estimate if you plan to work several more years, but the most accurate number comes after you actually claim.

Does my payment change after I start receiving it?

Your payment amount stays the same each month, but SSA adjusts all payments once per year for cost-of-living adjustments (COLA). This adjustment is announced in October and takes effect in January. The adjustment is the same percentage for all retirees and is based on inflation, so your payment may go up or down slightly depending on the year.

How do government pensions affect my Social Security calculation?

If you receive a pension from work where you did not pay Social Security taxes (such as some government jobs), two rules may reduce your Social Security payment: the Government Pension Offset and the Windfall Elimination Provision. These rules are complex and depend on your specific situation. SSA can tell you whether either rule applies to you once you contact them about claiming.

What if I made a lot more money in recent years than earlier in my career?

SSA uses your 35 highest-earning years, so recent high-earning years replace your lowest-earning years in the calculation. This means your payment reflects your strongest work years, not an average across your entire career. If you had very low earnings early on and much higher earnings later, your payment will be based primarily on those later, higher-earning years.
