# How One Small Move Before 65 Can Unlock a Bigger Social Security Benefit
Delaying Social Security past your full retirement age produces measurable financial gains, but a specific action taken before turning 65 can amplify those benefits further.
Social Security calculates your monthly payment based on your earnings history and the age when you claim. If you wait past your full retirement age (67 for most people born after 1960) to claim benefits, your payment grows by roughly 8 percent annually until age 70. That boost caps at age 70, meaning you gain nothing by waiting beyond then.
The "small move" that matters involves your work record itself. Continuing to work and earning income before 65 can replace lower-earning years in your calculation. Social Security bases your benefit on your 35 highest-earning years. If you have years of zero earnings or low earnings early in your career, continuing employment pushes out those weak years from the calculation.
Here's the practical impact: Someone with a gap year or lower earnings in their 30s could see their benefit increase by hundreds monthly by working a few more years before claiming. The Social Security Administration recalculates your benefit each year you work, factoring in new earnings immediately.
The math works differently depending on your situation. High earners who maxed out their contributions already see minimal gains from additional work income. People with spotty work histories or career interruptions benefit most. A 63-year-old returning to part-time work might add $100 to $400 monthly to their eventual benefit by age 70.
Claiming at 65 versus 67 costs you roughly 13.3 percent permanently. Claiming at 70 versus 67 gains you 24 percent permanently. Those percentages hold for life. The breakeven point where waiting exceeds claiming early happens around age 80
