Social Security Benefits Estimator

Estimate your monthly Social Security retirement benefit based on your earnings, work history, and when you plan to claim. See how claiming early or delaying past your Full Retirement Age affects your benefit, and compare cumulative lifetime payouts at every age from 62 to 70.

How Social Security Benefits Are Calculated

The Social Security Administration (SSA) uses a multi-step formula to determine your retirement benefit:

Step 1: Average Indexed Monthly Earnings (AIME)

SSA takes your highest 35 years of earnings (indexed for wage growth), totals them, and divides by 420 (35 years × 12 months) to arrive at your Average Indexed Monthly Earnings. If you worked fewer than 35 years, zeros are averaged in for the missing years, which lowers your AIME.

Step 2: Primary Insurance Amount (PIA)

Your PIA is calculated by applying a three-tier formula to your AIME using "bend points." For 2024, the formula is:

  • 90% of the first $1,226 of AIME
  • 32% of AIME between $1,226 and $7,391
  • 15% of AIME above $7,391

The result is truncated to the next lower dime. This PIA is the monthly benefit you receive if you claim at your exact Full Retirement Age.

Full Retirement Age (FRA)

Your FRA depends on your birth year. For those born in 1960 or later, FRA is 67. For those born between 1943 and 1959, FRA ranges from 66 to 66 and 10 months. Claiming before FRA permanently reduces your benefit; delaying past FRA increases it.

Early vs. Delayed Claiming

  • Claiming early (62 to FRA): Your benefit is reduced by 5/9 of 1% per month for the first 36 months before FRA, plus 5/12 of 1% for each additional month beyond 36.
  • Claiming at FRA: You receive 100% of your PIA.
  • Delaying (FRA to 70): You earn delayed retirement credits of 2/3 of 1% per month (8% per year) up to age 70.

Assumptions & Limitations

  • This estimator uses 2024 bend points ($1,226 / $7,391) and the 2024 taxable earnings cap ($176,100).
  • Actual AIME uses wage-indexed earnings for each year — we simplify by using your average annual earnings.
  • Cost-of-living adjustments (COLAs) are not included in these projections.
  • Spousal, survivor, and disability benefits are not covered by this tool.
