Social Security Calculator

This calculator estimates your monthly Social Security retirement benefit based on your earnings and planned claiming age.

• Current Age: used to estimate future years of contributions before retirement.
• Planned Retirement Age: you can claim Social Security as early as 62 or as late as 70. Claiming early permanently reduces your benefit. Waiting past full retirement age (67 for those born after 1960) permanently increases it.
• Annual Earnings: your current income is used to estimate your Average Indexed Monthly Earnings (AIME). The SSA actually uses your 35 highest earning years, adjusted for wage inflation.
• Years Worked: Social Security requires 40 credits (about 10 years of work) to qualify. Benefits are calculated on your highest 35 years. Fewer than 35 years of earnings means zeros are averaged in, reducing your benefit.

The SSA uses a three-step process:

Step 1: Calculate AIME (Average Indexed Monthly Earnings): take your 35 highest earning years, index them for wage inflation, add them up, and divide by 420 (35 years × 12 months).

Step 2: Apply the PIA formula (Primary Insurance Amount, your full retirement age benefit):

90% of the first $1,226 of AIME
+ 32% of AIME from $1,226 to $7,391
+ 15% of AIME above $7,391

Step 3: Adjust for claiming age:

• Claiming before 67 (FRA): benefit reduced 5/9% per month for the first 36 months early, then 5/12% per month beyond that. Claiming at 62 produces a ~30% reduction.
• Claiming after 67: benefit increases 8% per year (0.667%/month) up to age 70. Waiting from 67 to 70 adds 24% to your benefit.
