Few retirement decisions carry as much money on the table as when to claim Social Security. Claiming at 62 instead of 67 means lower checks for the rest of your life. Waiting past your full retirement age means bigger checks. Over a 25-year retirement, the difference can easily exceed $100,000. That's not pocket change.
The Basic Tradeoff
Your Social Security benefit is calculated based on your 35 highest-earning years, indexed to wage growth. Then it's adjusted for the age you claim. The "full retirement age" (FRA) depends on your birth year — for most people today, it's 67. Claim before FRA and your benefit shrinks by about 6.67% per year (5/6 of 1% per month) for up to three years early. Claim after FRA and it grows by 8% per year, up to age 70.
So if your FRA benefit is $2,000/month: at 62 it might be $1,400. At 70, it could be $2,480. The math is brutal and permanent.
The Break-Even Analysis
Here's the number nobody talks about enough: if you claim at 62 instead of 67, you receive about 5 years of checks. The break-even point where the person who waited finally catches up is roughly 12-14 years after 67 — so age 79-81. Live past that, and waiting wins. Die before it, and claiming early wins.
That's a coin flip that depends on your health, family longevity, and how much you hate spreadsheets.
Why People Claim Early Anyway
Health matters. If your doctor has given you reasons to expect a shorter life, claiming early at 62 makes mathematical sense — you get more total money by taking it while you can. Family history of early mortality shifts the odds.
Job loss is another big reason. If you're 62 and unemployed, Social Security becomes income. It's not ideal, but it's real. Nobody should starve for ideological purity about optimization.
And some people just hate having money they can't spend. There's a psychological benefit to taking money off the table. Financial therapy, not just financial planning, has a role here.
The Spousal and Survivor Dimension
Married couples have an additional lever: the spousal benefit. If one spouse earned significantly less, that spouse can claim a spousal benefit (up to 50% of the higher earner's FRA benefit) while the higher earner delays. This lets the couple's total household benefit peak at 70 while one spouse claims early.
Survivor benefits are equally important. When one spouse dies, the survivor gets the higher of the two benefits — not both. This means the lower earner should often delay as long as possible: their survivor benefit is based on their own FRA benefit, not their late spouse's. The higher earner claiming early can reduce the survivor's long-term security.
The Earnings Test
Before FRA, Social Security has an earnings test. Earn too much from work and they withhold $1 for every $2 over the limit ($22,320 in 2024). At FRA itself, it's $1 withheld for every $3 over $59,520. After FRA, there's no test — you can earn anything and collect full benefits.
For people still working at 62-66, this can make claiming early feel like a trap. You're earning too much to collect, and the benefit is reduced anyway. Sometimes it's better to wait until you actually stop working.
What Most People Get Wrong
The conventional wisdom "wait as long as possible" is mathematically correct for most people who can afford to wait — but "can afford to wait" is doing a lot of work in that sentence. If waiting means drawing down retirement savings at 7% returns instead of 4%, the break-even analysis changes.
The single biggest mistake is claiming at 62 just because you can, without running the actual numbers. Use our Social Security estimator, compare claiming ages with a spreadsheet, and factor in your health. It's one of the highest-stakes calculations of your retirement.
