Your benefit amount depends on when you start collecting and your earnings history

Social Security does not pay the same amount to everyone. The amount you receive depends on two things: how much you earned during your working years, and what age you start collecting. The Social Security Administration (SSA) calculates your benefit based on your 35 highest-earning years. If you worked fewer than 35 years, they count zeros for the missing years, which lowers your benefit.

When you start collecting also changes how much you get each month. If you start at 62, you receive less per month than if you wait until 67 or 70. This is called your primary insurance amount (PIA) — the benefit you would receive if you start at your full retirement age. Starting earlier means a permanent reduction. Starting later means a permanent increase.

The SSA publishes the average benefit amounts each year, but your personal benefit will be different based on your specific earnings record. You can see your estimated benefit by creating an account at ssa.gov and viewing your Social Security Statement.

Key Takeaways

  • Your monthly benefit is calculated from your 35 highest-earning years, so gaps in work history lower your payment.
  • Starting at 62 reduces your monthly benefit by roughly 30 percent compared to starting at your full retirement age, which varies by birth year.
  • Waiting until 70 increases your monthly benefit by roughly 24 to 32 percent compared to your full retirement age.
  • The SSA publishes average benefit amounts each year, but your actual benefit depends on your earnings record and start date.
  • You can view your personalized estimate by creating a my Social Security account at ssa.gov.

How your full retirement age affects your benefit

Your full retirement age (FRA) is the age at which you receive 100 percent of your calculated benefit. This age is not 65 for everyone — it depends on the year you were born. For people born between 1943 and 1954, full retirement age is 66. For people born between 1955 and 1959, it increases by two months for each birth year. For people born in 1960 or later, full retirement age is 67.

Your full retirement age is the reference point for all other benefit amounts. If you start before your FRA, your benefit is reduced. If you start after your FRA, your benefit is increased. The reduction or increase is permanent — it does not change once you start collecting.

For example, if your full retirement age is 67 and your calculated benefit at that age is $1,500 per month, starting at 62 would give you roughly $1,050 per month for life. Starting at 70 would give you roughly $1,860 per month for life. These are approximate figures; your actual reduction or increase depends on your exact birth month and the SSA's current formulas.

Benefit reductions for starting before full retirement age

If you start collecting before your full retirement age, the SSA reduces your monthly benefit. The reduction is steeper the earlier you start. Starting at 62 — the earliest age you can collect — results in the largest reduction.

The reduction is roughly 6.67 percent per year for the first three years before your FRA, and 5 percent per year for each year before that. This means if your FRA is 67, starting at 64 (three years early) reduces your benefit by roughly 20 percent. Starting at 62 (five years early) reduces it by roughly 30 percent. The exact percentage depends on your birth year.

This reduction is permanent. Even after you reach your full retirement age, your monthly payment will still be reduced because you started early. The only exception is if you start collecting and then change your mind within a certain window — the SSA allows you to withdraw your process within 12 months of starting, but this is rarely done and has tax consequences.

Benefit increases for starting after full retirement age

If you delay starting Social Security past your full retirement age, your monthly benefit increases. This increase is called delayed retirement credits. You earn one credit for each month you delay, up until age 70. After 70, your benefit stops increasing, so there is no financial reason to delay past that age.

The increase is roughly 8 percent per year. If your FRA is 67 and you wait until 70, your benefit increases by roughly 24 percent. If your FRA is 66 and you wait until 70, your benefit increases by roughly 32 percent. Like the early-start reduction, this increase is permanent.

Delaying makes the most sense if you expect to live a long time, have other income to live on until 70, or want to maximize the benefit your spouse or children receive based on your record. The break-even point — where waiting until 70 gives you more total money than starting at 62 — is usually around age 80 or 81, depending on your FRA.

How earnings history affects your benefit amount

The SSA bases your benefit on your 35 highest-earning years. If you worked more than 35 years, they use only your top 35. If you worked fewer than 35 years, they count zeros for the missing years, which significantly lowers your benefit.

For example, if you worked 30 years and then stopped, the SSA counts five years of zero earnings in your calculation. This five-year gap reduces your average earnings and therefore your benefit. Each additional year you work can replace a zero year or a lower-earning year, which increases your benefit.

The SSA adjusts your earnings for inflation using a formula called wage indexing. This means earnings from 30 years ago are adjusted upward to reflect what they would be worth in current dollars. You do not need to do this calculation yourself — the SSA does it when they compute your benefit.

Average benefit amounts and annual adjustments

The SSA publishes average benefit amounts each month. These are the amounts the typical person receives, but your benefit will likely be different. The average benefit for a retired worker varies widely based on earnings history and start age.

Workers who earned higher wages throughout their careers receive higher benefits. Workers who had gaps in employment or lower wages receive lower benefits. Someone who started at 62 receives less per month than someone who started at 67, even if they had identical earnings histories.

The SSA adjusts all benefits each year for inflation using the Cost of Living Adjustment (COLA). This means your monthly payment increases slightly most years to keep pace with rising prices. The COLA is the same percentage for everyone, but the dollar amount of the increase depends on your benefit size.

How to find your personalized benefit estimate

The best way to know what you will receive is to check your personalized estimate. You can create a free account at ssa.gov using your email address and Social Security number. Once you log in, you can view your Social Security Statement, which shows your earnings history and estimated benefits at different start ages.

Your statement shows estimates for starting at 62, your full retirement age, and 70. These estimates are based on the assumption that you continue working at your current pace until you start collecting. If you plan to retire early or work longer, your actual benefit may be different.

You can also call the SSA at 1-800-772-1213 to request a paper statement, though the online account is faster. The SSA does not send statements automatically anymore, so you must request one yourself.

Frequently Asked Questions

Does my spouse's benefit depend on my start age?

Yes. If your spouse collects a benefit based on your earnings record, their benefit is also affected by when you start. If you delay until 70, your spouse's benefit based on your record also increases. This is one reason some people choose to delay — it can increase the total household benefit.

What if I worked in another country?

The SSA counts only earnings from U.S. employment toward your benefit. If you worked in another country, those years do not count unless there is a totalization agreement between the U.S. and that country. You can ask the SSA whether your work history qualifies.

Can I see what I would get if I start at age 65?

Your Social Security Statement shows estimates for 62, your full retirement age, and 70. To see an estimate for 65, you would need to contact the SSA directly or use their online calculator, which lets you enter any age between 62 and 70.

Does my benefit change after I start collecting?

Your monthly benefit amount stays the same, but it increases each year with the Cost of Living Adjustment. The percentage increase is the same for everyone, but the dollar amount depends on your benefit size. Your benefit does not change based on how much money you have or other income you receive, except in rare cases involving government pensions.

What if I was married more than once?

You may be able to collect a benefit based on a former spouse's earnings record if you were married for at least 10 years, are at least 62, and are not currently married. This benefit does not reduce your ex-spouse's benefit. You can ask the SSA whether you may have access to based on your specific situation.
