Deciding when to start Social Security is one of the highest-stakes choices in retirement planning. You can begin as early as age 62 or wait as late as 70, and the age you pick locks in a benefit amount that follows you for the rest of your life and, in many cases, your spouse's life too. The difference between the earliest and latest claim can be 75% or more in monthly income.
Every other claiming decision is measured against your Full Retirement Age (FRA). The Social Security Administration defines FRA based on your birth year: it is 66 for people born from 1943 through 1954, then rises in two-month steps, reaching 67 for anyone born in 1960 or later. At your FRA you receive 100% of your "primary insurance amount," the benefit calculated from your top 35 years of earnings.
Claim before FRA and the Social Security Administration permanently reduces your monthly check. Claim after FRA and you earn delayed retirement credits that permanently increase it. Neither adjustment goes away later, so the decision is essentially irreversible once it has been in place beyond the brief withdrawal window.
Claiming at 62 reduces a benefit by roughly 25% to 30% compared with FRA, depending on whether your FRA is 66 or 67. Waiting past FRA adds delayed retirement credits of about 8% for each full year you delay, up to age 70 (there is no benefit to waiting beyond 70). The table below illustrates these standard Social Security Administration percentages on a sample worker whose full benefit at an FRA of 67 is $2,000 per month.
| Claiming age | Adjustment vs. FRA | Illustrative monthly benefit | Illustrative annual benefit |
|---|---|---|---|
| 62 (earliest) | About 30% reduction | $1,400 | $16,800 |
| 65 | About 13% reduction | $1,733 | $20,800 |
| 67 (Full Retirement Age) | 100% (no adjustment) | $2,000 | $24,000 |
| 68 | About 8% delayed credit | $2,160 | $25,920 |
| 70 (latest worth waiting for) | About 24% delayed credit | $2,480 | $29,760 |
These numbers are illustrative and rounded, but the percentages match the standard rules published by the Social Security Administration. In this example the age-70 benefit is roughly 77% larger than the age-62 benefit, every year, for life.
Claiming early gives you smaller checks but more of them; delaying gives you larger checks but fewer years of them. The "break-even age" is the age at which the larger delayed benefit catches up to and overtakes the total dollars you would have collected by claiming early. For a delay from 62 to 70, the break-even typically lands somewhere in the late seventies to early eighties.
That makes longevity the central variable. If you live well past your break-even age, delaying wins by a wide margin. If you do not, claiming early collects more total cash. Because no one knows their own lifespan, the honest inputs are your current health, your family history, and whether you have a spouse who may depend on your record. People in good health with long-lived relatives generally lean toward waiting.
If you claim before your Full Retirement Age and keep working, the Social Security Administration applies a "retirement earnings test." Earn above an annual limit and the agency temporarily withholds part of your benefit. In the year you reach FRA the limit is much higher and the withholding lighter, and once you actually reach FRA the earnings test disappears entirely no matter how much you earn. Importantly, withheld amounts are not lost forever: the Social Security Administration recalculates and credits them back through a higher benefit once you reach FRA. Still, the earnings test is a strong reason not to claim early if you plan to keep working substantially.
Your claiming age does not only affect you. A married worker who delays raises the survivor benefit their spouse can receive after they die. When one spouse passes away, the survivor generally keeps the larger of the two benefits, so a higher earner who waits to 70 is effectively buying a bigger lifetime income for whichever spouse lives longer. This is why couples are often advised to have the higher earner delay even if the lower earner claims earlier.
Social Security income can be partly taxable. Under IRS rules, the share of your benefits subject to federal income tax depends on your "combined income," roughly your adjusted gross income plus nontaxable interest plus half of your Social Security benefits. Depending on where that figure falls relative to the IRS thresholds, anywhere from 0% up to 85% of your benefits may be taxable. No one pays tax on more than 85% of their benefits, but higher-income retirees should expect that most of their Social Security will be taxed. Check the current thresholds with the IRS, since they are not automatically indexed to inflation.
Financial planners often describe delaying Social Security as the cheapest longevity insurance available. The increase from delayed retirement credits is guaranteed, backed by the federal government, and adjusted for inflation through annual cost-of-living adjustments. There is no commercial annuity that reliably matches that combination. Spending down other savings in your sixties to bridge the gap until a larger age-70 benefit can be a rational trade: you convert a portion of a portfolio that might run out into a guaranteed, inflation-protected income that never does.
The figures here are illustrations. Your actual numbers come from your own earnings record. Create a free "my Social Security" account at SSA.gov to see your projected benefit at 62, at your Full Retirement Age, and at 70, then plug those into your broader retirement plan. The Social Security Administration's estimator uses your real earnings history, which is far more accurate than any rule of thumb.
Yes. Claiming early can make sense if you have serious health concerns, a shorter life expectancy, an urgent need for income, or no other resources to live on. It can also help a lower-earning spouse start some income while the higher earner delays. The right answer depends on your full situation, not a single rule.
Only within narrow limits. The Social Security Administration allows a one-time withdrawal of your application within 12 months of claiming if you repay what you received, and people who reached FRA can voluntarily suspend benefits to earn delayed credits. Outside those windows the decision is permanent.
No. Delayed retirement credits stop accruing at age 70, so there is no financial reason to wait beyond that. If you have not claimed by 70, file promptly.
Federal taxation follows the IRS combined-income rules described above. State treatment varies widely, with many states exempting Social Security entirely. Confirm your own state's rules, as they change over time.
