The Nationwide Retirement Institute reports that only 8% of surveyed adults can identify all the factors that determine the maximum Social Security benefit. That is problematic because Social Security is generally the largest source of income in retirement, meaning benefits have a substantial impact on living standards for millions of Americans

How Social Security benefits are calculated for retired workers
The Social Security Administration (SSA) uses three variables to calculate Social Security benefits for retired workers: (1) work history, (2) lifetime earnings, and (3) claiming age.
The first step is determining the primary insurance amount (PIA), the benefit a worker receives if they start Social Security at full retirement age (FRA). The PIA is calculated by plugging inflation-adjusted earnings from the 35 highest-paid years of work into the benefits formula, which changes annually to account for increases in the average wage.
The second step is adjusting the PIA for early or delayed retirement. Workers who claim Social Security before FRA receive a smaller payout, typically less than 100% of their PIA. Workers who claim Social Security later than FRA get a larger payout, meaning more than 100% of their PIA.
How retired workers earn the maximum Social Security benefits
Now that I’ve covered how Social Security benefits are calculated, we can discuss how to maximize them by revisiting the three variables from the previous section.
-
Work history: The benefits formula includes income from the 35 highest-paid years of work. That means workers must spend at least 35 years in the workforce to get the maximum benefit. Workers employed for fewer than 35 years will have zeroes factored into the benefits formula, making them ineligible for the biggest payout.
-
Lifetime income: The benefits formula only considers earnings up to the maximum taxable limit. That means workers must have income at or above the taxable maximum for at least 35 years to qualify for the biggest Social Security benefit. The taxable maximum is $184,500 in 2026, but it typically increases each year to reflect changes in the average wage.
-
Claim age: Workers who claim Social Security benefits after FRA earn delayed retirement credits that increase their payments by two-thirds of 1% per month, or 8% per year. But delayed retirement credits stop accumulating at age 70, meaning workers must claim Social Security at age 70 to earn the absolute maximum Social Security benefit.
