Frequently Asked Questions
How is my Social Security benefit calculated?
The SSA averages your 35 highest-earning years (indexed for wage growth) into your AIME, then applies bend-point percentages — 90%, 32%, and 15% of successive slices — to get your PIA, the benefit at Full Retirement Age. Claiming earlier or later then adjusts that amount. This calculator applies the 2025 formula to your entered income as an estimate.
What is Full Retirement Age (FRA)?
FRA is the age you receive 100% of your benefit. For anyone born in 1960 or later it is 67. Claim before FRA and your monthly check is permanently reduced; claim after and it is permanently increased.
How much less do I get by claiming at 62?
About 30% less than at FRA. The reduction is 5/9 of 1% per month for the first 36 months early, plus 5/12 of 1% for each additional month. Sixty months early (age 62) totals a 30% cut — so a $2,000 FRA benefit becomes about $1,400.
How much more do I get by waiting until 70?
About 24% more than at FRA. You earn delayed-retirement credits of 2/3 of 1% per month (8% per year) from 67 to 70. There is no benefit to waiting past 70, so 70 is the maximum-benefit age.
Is this the same as the official SSA estimate?
No — it is an approximation. The real figure depends on your full 35-year indexed earnings history, which only the SSA has. Treat this as a planning ballpark and check your personal estimate at ssa.gov/myaccount.
