How Your Social Security Benefit Is Really Calculated
Social Security retirement benefits aren't simply proportional to what you paid in โ they use a formula based on Average Indexed Monthly Earnings (AIME) that favors lower earners with a higher replacement rate. The Social Security Administration applies "bend points" to your AIME: a high percentage on the first portion, a lower percentage on the next portion, and an even lower percentage above that. This calculator uses a simplified version of that idea โ it adjusts your average income for years worked below 35 (since SSA averages in zero-earning years for a shorter career) and then applies approximate 2025 bend points to estimate your Primary Insurance Amount.
Values Used in This Estimate
| Item | Meaning |
|---|---|
| Eligibility | Minimum 10 years (40 credits) of covered work |
| Work-year factor | min(years worked, 35) รท 35 |
| Bend points (approx.) | 90% up to $1,226/mo, 32% up to $7,391/mo, 15% above |
This is a simplified, reference-only estimate. Your actual benefit depends on your full 35-year earnings history, wage indexing, your claiming age (benefits are reduced if you claim before your full retirement age and increased if you delay), and annual cost-of-living adjustments.

Frequently Asked Questions
At least 10 years (40 work credits) of covered work. Fewer years than that generally means no retirement benefit.
