Social Security Calculator
Estimate how claiming Social Security early or late changes your monthly benefit compared to your full retirement age amount.
- Age 62$1,540.00
- Full Retirement (67)$2,200.00
- Age 70$2,728.00
- Age 65$1,906.67
Claiming at 65 instead of your full retirement age of 67 changes your monthly check by $293.33 — the difference locks in for life.
Simplified estimate using standard SSA early/delayed retirement adjustment rules — your actual benefit depends on your full earnings record.
About the Social Security Calculator
Social Security doesn't pay the same monthly amount no matter when you start claiming it — your benefit is anchored to your full retirement age (FRA) amount, then permanently reduced for every month you claim early or increased for every month you delay past FRA, up to age 70. Treating the FRA figure as the only number that matters overlooks that claiming timing alone can swing your monthly check by a large percentage, locked in for life.
This is the calculator for the decision nearly every future retiree eventually faces: claim as soon as eligible at 62 for a smaller check sooner, wait until full retirement age, or delay to 70 for the largest possible monthly benefit — a decision with real tradeoffs around income needs, health, and other savings, not just around the raw dollar figure.
Your benefit estimate and claiming plans stay entirely in your browser — nothing about your projected Social Security income, which is about as sensitive a retirement number as there is, gets sent anywhere or requires an account to check.
How it’s calculated
Starting from your benefit at full retirement age, this calculator applies the SSA's standard adjustment: claiming early reduces the benefit by roughly 5/9 of 1% per month for the first 36 months early, then 5/12 of 1% per month beyond that; claiming after FRA increases it by roughly 2/3 of 1% per month, up to age 70 (delaying further adds nothing).
The comparison table shows your benefit at age 62, your full retirement age, age 70, and whatever claiming age you enter, so you can see the full range side by side rather than just one number in isolation.
Frequently asked questions
What's the actual difference between claiming at 62 versus waiting until 70?
The gap is substantial — claiming at the earliest possible age locks in a meaningfully reduced check compared to your full retirement age amount, while waiting until 70 delivers a meaningfully larger one, and the difference compounds over what could be decades of payments. This calculator's comparison table shows the exact percentages for your own benefit amount.
Is it ever smarter to claim early even though the check is smaller?
Sometimes — claiming early can make sense if you have a shorter life expectancy, need the income now, or want to preserve other retirement savings from being drawn down early. It's a genuinely personal decision, not just a math problem, since the 'right' answer depends heavily on how long you actually end up collecting.
How is my full retirement age determined?
It's set by the SSA based on your birth year — it has gradually shifted from 65 toward 67 for people born in more recent years. Your specific FRA determines both the reference point this calculator starts from and exactly how many months of early or delayed adjustment apply at any claiming age.
Does this calculator give my exact Social Security benefit?
No — it's a simplified estimate that applies the standard claiming-age adjustment to a benefit figure you provide. Your actual FRA benefit depends on your full lifetime earnings record, which the Social Security Administration calculates directly and shows on your personal statement.
Does delaying benefits past age 70 increase them further?
No — the delayed retirement credit stops accruing at age 70, so there's no additional benefit to waiting past that point. Claiming exactly at 70 captures the full increase without leaving any further growth on the table.
