How This Social Security Calculator Works
Enter your average yearly earnings, how many years you have worked, your birth year and the age you plan to claim. The calculator finds your average indexed monthly earnings, applies Social Security's benefit formula to get your full benefit (the primary insurance amount, or PIA), and then adjusts it for claiming early or late. A table compares every claiming age from 62 to 70.
Quick explanation: claiming early lowers your check for life, and waiting raises it.
- 62: the earliest age, up to 30% less for people born in 1960 or later.
- Full retirement age: 67 for people born in 1960 or later.
- 70: the largest benefit, up to 24% more than at 67.
How to Use the Social Security Calculator
- Enter your average yearly earnings in today's dollars.
- Enter how many years you have worked or expect to work.
- Enter your birth year.
- Choose the age you plan to claim.
- Press Calculate and compare the table of claiming ages.
Core Formulas
- AIME: highest 35 years of indexed earnings ÷ 420 months
- PIA: 90% of AIME up to $1,340 + 32% from $1,340 to $8,077 + 15% above $8,077
- Early: −5/9 of 1% per month for the first 36 months, then −5/12 of 1% per month
- Delayed: +8% per year (2/3 of 1% per month) after full retirement age, up to 70
Key Terms
- AIME: average indexed monthly earnings, your top 35 years of earnings adjusted for wage growth.
- PIA: primary insurance amount, your benefit at full retirement age.
- Bend points: the dollar amounts where the PIA formula changes from 90% to 32% to 15%.
- Full retirement age: the age when you get 100% of your PIA.
- Delayed retirement credits: increases for claiming after full retirement age, up to 70.
Worked Example
You earned $60,000 a year on average for 35 years and were born in 1965.
- AIME = $60,000 ÷ 12 = $5,000
- PIA = 90% × $1,340 + 32% × ($5,000 − $1,340) = $2,377
- At 62: 60 months early, a 30% cut, so about $1,664. At 70: 36 months late, 24% more, so about $2,947.
Real-Life Examples
- Choosing when to claim: compare 62, 67 and 70 side by side.
- Higher earner: $120,000 a year for 35 years gives a full benefit of about $3,650 a month.
- Short career: $60,000 for only 20 years gives about $1,691, as zeros are averaged in.
- Retirement budget: add the estimate to your savings plan in our Retirement Calculator.
Claiming at 62 vs 67 vs 70
- 62: smaller checks, but more years of them.
- 67: your full benefit if you were born in 1960 or later.
- 70: the largest checks. Waiting tends to pay off if you live into your 80s.

| Year of birth | Full retirement age | Benefit at 62 |
|---|---|---|
| 1943–1954 | 66 | 75% |
| 1955 | 66 and 2 months | 74.17% |
| 1956 | 66 and 4 months | 73.33% |
| 1957 | 66 and 6 months | 72.5% |

| 1960 and later | 67 | 70% |
What Changes Your Benefit
- Earnings: higher lifetime earnings raise your benefit, up to the taxable maximum.
- Years worked: fewer than 35 years means zeros are counted in the average.
- Claiming age: each month you wait changes the benefit.
- Cost-of-living raises: benefits usually rise each year with inflation.
Common Mistakes to Avoid
- Using your final salary. The formula uses your average over 35 years, not your last paycheck.
- Forgetting zero years. Fewer than 35 years of work lowers the average.
- Thinking early claiming is temporary. The reduction lasts for life.
- Waiting past 70. Delayed credits stop at 70.
- Ignoring spouse benefits. A spouse may get more from your record. Check with SSA.
