When Should You Claim Social Security?

Most people pick 62 because it's the earliest they can. Some pick 67 because it's the "full" retirement age. Almost nobody picks 70 — even though, for most people who live past 80, it's the best financial decision they can make.

The reason is that Social Security is the only financial product most people will ever own that guarantees an 8% annual return, is inflation-adjusted for life, and cannot be outlived. Every year you delay between 62 and 70 locks in that 8% permanently. If you live to 85, claiming at 70 instead of 62 typically puts $150,000 to $300,000 more in your pocket over your lifetime. If you have a spouse, the calculus gets even more important — because the higher earner's benefit becomes the survivor benefit, and a widow or widower living to 90 on a reduced benefit is one of the most common and preventable retirement mistakes there is.

This calculator shows your monthly benefit at every claiming age, your lifetime total at ages 80, 85, 90, and 95, the exact age where each strategy breaks even, the optimal strategy for you and your spouse as a couple, and an honest look at whether claiming early and investing the difference could ever beat waiting. Put in your numbers and see what the decision is actually worth.

Monthly benefit at FRAYour estimated benefit at Full Retirement Age (67 for those born 1960 or later). Find this on your Social Security statement at ssa.gov or create an account at my.ssa.gov.
Life expectancyThe single biggest driver of which claiming age is optimal. The longer you live, the more delaying pays off. The break-even for claiming at 70 vs 62 is typically around age 80-81.

Spousal benefits
Spousal benefitA spouse can claim up to 50% of your Full Retirement Age benefit, even with little or no work history of their own. This is automatic - they receive whichever is higher, their own benefit or the spousal benefit.
Survivor benefitWhen one spouse dies, the survivor receives 100% of the higher earner's benefit. This makes the higher earner's claiming decision especially important - delaying to 70 maximizes the survivor benefit for life.

Assumptions
COLA (Cost of Living Adjustment)The annual increase Social Security applies to benefits. The historical average is around 2.5%. A higher base benefit from delaying means every future COLA increase is worth more in dollar terms.
Investment returnUsed to model the opportunity cost scenario: if you claim early and invest the payments at this return rate, does that strategy eventually outperform waiting? Most analyses find you need 7-8% to beat delaying to 70.
Annual COLA (cost of living adjustment) 2.5%
Investment return (if claiming early) 6.0%

Actual benefits depend on your full earnings history, the SSA benefit formula, taxation of benefits (up to 85% of SS income may be taxable), Medicare premium offsets, and other factors not modeled here. The Full Retirement Age of 67 applies to those born in 1960 or later. Consult the SSA website (ssa.gov) or a qualified financial advisor before making claiming decisions.
