How Social Security benefits are calculated

Your Social Security retirement benefit is based on your Primary Insurance Amount (PIA), calculated from your Average Indexed Monthly Earnings over your 35 highest-earning years. The PIA is your benefit at your Full Retirement Age. This calculator accepts your estimated FRA benefit directly — find it at ssa.gov/myaccount.

Early and late claiming adjustments

Claiming before FRA: benefit reduced by 5/9% per month for first 36 months early
then 5/12% per month for each additional month before FRA
Maximum reduction: claiming at 62 with FRA 67 = 30% reduction

Claiming after FRA: benefit increased by 8% per full year delayed (2/3% per month)
Maximum increase: claiming at 70 with FRA 67 = 24% above FRA benefit

COLA applied annually to the adjusted monthly benefit

Frequently asked questions

No. Whether delaying is optimal depends entirely on how long you live. The Social Security system is designed to be approximately actuarially neutral for someone with average life expectancy, meaning the total lifetime benefit should be roughly the same regardless of when you claim if you live to an average age. For someone in poor health with a family history of early mortality, claiming at 62 maximises lifetime benefits. For someone expecting to live into their 90s, delaying to 70 is likely optimal. Spousal and survivor benefits add another dimension.

COLA applies as a percentage to whatever benefit you are receiving. Because a delayed claim produces a higher base benefit, COLA increases compound on a larger number each year. Someone who delays to 70 and receives $3,000 per month will see their benefit rise by $75 in a 2.5% COLA year. Someone who claimed at 62 and receives $2,100 per month sees only a $52.50 increase. Over 20 to 30 years of retirement, the compounding effect of COLA on a higher base benefit becomes substantial.

If you claim Social Security before your FRA and continue working, SSA withholds $1 of benefit for every $2 of earnings above the annual earnings limit. Importantly, the withheld benefits are not lost permanently — SSA recalculates your benefit at FRA and credits you for months benefits were withheld, giving you a higher monthly benefit going forward. After you reach FRA, the earnings test no longer applies and you can earn any amount without affecting your benefit.
