How Social Security Retirement Benefits Are Calculated in 2025
The Social Security Administration (SSA) calculates your retirement benefit using a three-step formula that may seem complex, but once understood, allows you to make strategic claiming decisions worth tens of thousands of dollars over your lifetime.
Step 1: Calculate your AIME. SSA takes your 35 highest-earning years (adjusting each year's earnings for wage inflation), adds them up, and divides by 420 months. This is your Average Indexed Monthly Earnings (AIME). Zero-earning years count as $0, which is why working at least 35 years is important.
Step 2: Apply the bend point formula. SSA applies a
progressive formula using 2025 bend points ($1,226 and $7,391):
• 90% of the first $1,226 of AIME
• 32% of AIME between $1,226 and $7,391
• 15% of AIME above $7,391
This formula heavily favors lower earners. A worker with an AIME of $1,000 receives about 90% of it ($900/mo), while someone with an AIME of $10,000 receives about 40% ($4,018/mo). The result of the formula is called your PIA — Primary Insurance Amount — which is what you receive at Full Retirement Age (67).
