When to Claim Social Security: The Math Behind the Decision

March 14, 2026 · 5 min read

Claiming Social Security too early can cost you $100,000+ in lifetime benefits. Claiming too late means missing years of income. Find your optimal age with our Social Security Break-Even Calculator.

The Numbers

For someone with a $2,500/month benefit at 67 (FRA): At 62 you get $1,750/month (30% reduction). At 70 you get $3,100/month (24% increase). The difference between 62 and 70 is $1,350/month — over $16,000/year.

Break-Even Analysis

Claiming at 67 vs 62: break-even around age 78-80. Claiming at 70 vs 67: break-even around 80-83. If you live past these ages, delaying pays more. Average life expectancy at 65 is about 85 — meaning delaying usually wins.

The Spouse Factor

Survivor benefits are based on the higher earner's benefit. If you're the higher earner, delaying to 70 protects your spouse with a larger survivor benefit for life.
