How to Use This Social Security Calculator
Follow these four steps to estimate your Social Security retirement benefit:
- Enter your birth year — used to determine your Full Retirement Age (FRA), which varies from 66 to 67 depending on when you were born.
- Enter your annual earnings — used to estimate your Average Indexed Monthly Earnings (AIME) and Primary Insurance Amount (PIA) at FRA.
- Enter years worked — benefits are based on your top 35 earning years. Fewer years reduces your benefit proportionally.
- Choose your claiming age — compare how early (age 62) vs. full (FRA) vs. delayed (age 70) claiming affects your monthly benefit and estimated lifetime payout.
Social Security Formulas & Bend Points
Primary Insurance Amount (PIA) — 2025 Bend Points
The PIA is calculated by applying graduated rates to your Average Indexed Monthly Earnings (AIME):
90% × AIME up to $1,226+ 32% × (AIME from $1,226 to $7,391)+ 15% × (AIME above $7,391)Example: AIME of $5,000 → (90% × $1,226) + (32% × $3,774) = $1,103 + $1,208 = $2,311/mo PIA
Early Claiming Reduction
Claiming before your FRA permanently reduces your monthly benefit:
First 36 months early: −5/9% per month (≈ −6.67%/year)
Beyond 36 months early: −5/12% per month (≈ −5%/year)Maximum reduction at age 62 with FRA of 67: −30% (60 months early).
Delayed Retirement Credit
+2/3% per month delayed past FRA (= +8% per year)Delaying from FRA 67 to age 70 (36 months) increases your benefit by +24%. Credits stop accruing at age 70.

Frequently Asked Questions
You can begin collecting as early as age 62 and as late as age 70. Your Full Retirement Age (FRA) depends on your birth year. Claiming early permanently reduces benefits; delaying past FRA permanently increases them.
FRA is 66 for those born 1943–1954, gradually increasing to 67 for those born 1960 or later. Born 1955: 66+2 months, 1956: 66+4 months, 1957: 66+6 months, 1958: 66+8 months, 1959: 66+10 months, 1960 or later: 67.
Claiming at 62 (maximum early claiming) reduces benefits by up to 30% for those with an FRA of 67. The reduction is 5/9% per month for the first 36 months before FRA, then 5/12% per month beyond that.
For every month you delay past FRA (up to age 70), your benefit increases by 2/3% per month (8% per year). Delaying from FRA 67 to 70 increases benefits by 24%.
SSA calculates your Average Indexed Monthly Earnings (AIME) from your top 35 earnings years. Your Primary Insurance Amount (PIA) is then calculated using bend points applied to your AIME. This calculator uses a simplified earnings-based estimate.
In 2025, the maximum monthly benefit for someone claiming at FRA is approximately $3,822. At age 70, the maximum is about $5,108/month. The exact amount depends on your full 35-year earnings history.
