Social Security Benefit Calculator
Use this calculator to estimate your Social Security benefits.
How the social security benefit calculator works
It estimates your average indexed monthly earnings, applies the Social Security benefit formula’s bend points to get your full-retirement benefit, then adjusts it up for claiming later or down for claiming early.
Worked example: with average annual earnings (career) of $60,000 and age you claim benefits of 67, the social security benefit calculator shows estimated monthly benefit of $2,280.92.
- Full-retirement benefit (PIA)
- $2,280.92
- Benefit at age 67
- $2,280.92
- Claiming adjustment
- 0%
- Annual benefit
- $27,371
The formula
PIA = 90% of first bend + 32% of middle + 15% of top of AIME. Benefit = PIA × claiming factor (reduced before 67, +8%/yr to 70).

Questions about the social security benefit calculator
How is my Social Security benefit calculated?
From your highest 35 years of inflation-adjusted earnings, run through a progressive formula, then adjusted for the age you claim. This tool gives a simplified estimate of that.
Should I claim at 62, 67 or 70?
Claiming early permanently reduces your benefit; waiting until 70 increases it about 8% a year past full retirement age. The right age depends on your health, finances and other income.
How accurate is this estimate?
It is a simplified approximation. Your official benefit depends on your full earnings record — create an account at ssa.gov for a personalized estimate.
