Social Security Estimator

See how claiming Social Security early, at full retirement age, or later changes your monthly benefit.

Estimate only — not advice. This tool provides a simplified, general estimate for educational purposes.

What this estimate assumes

The claiming-age adjustment (the percentage your benefit is reduced before, or increased after, your Full Retirement Age) uses the SSA's official published formula: 5/9 of 1% per month for the first 36 months early, 5/12 of 1% per month beyond that, and 2/3 of 1% (8%/year) per month of delay up to age 70.
Your Full Retirement Age is calculated from your birth year using the SSA's standard table (66 for anyone born 1943–1954, rising in two-month steps to 67 for anyone born 1960 or later).
"Estimate from my current salary" mode is a rough approximation: it treats your current salary as if it represented your average earnings across your career and applies the 2026 bend-point formula (90% / 32% / 15%). It ignores your real earnings history, so it can be significantly off — especially early or late in a career. Use "I know my benefit" mode with the number from your ssa.gov statement whenever possible.
