Compare all 97 claiming months.
Move the slider. Each month recalculates from the reduction and credit factors SSA publishes.
Your optimal month depends on your record — run that in about a minute.
Example record: $2,000 a month at full retirement age 67. Your own record replaces it when you create a free account and load your SSA statement.

How to read this: The lines show the total money you'd have received from Social Security by each age. At 67 (Full Retirement Age), you get your full benefit without reduction or bonus.

Age 67: $2,000 a month, $24,000 a year.
Every claiming age on the example record
The same math the slider runs, laid out for all nine ages. Percentages are of the full retirement age benefit and hold for anyone whose full retirement age is 67 (born 1960 or later); the dollar column is the $2,000 example.
| Claiming age | Share of full benefit | Monthly (example) | Annual (example) |
|---|---|---|---|
| 62 | 70% | $1,400 | $16,800 |
| 63 | 75% | $1,500 | $18,000 |
| 64 | 80% | $1,600 | $19,200 |
| 65 | 86.7% | $1,733 | $20,796 |
| 66 | 93.4% | $1,867 | $22,404 |
| 67 (full retirement age) | 100% | $2,000 | $24,000 |
| 68 | 108% | $2,160 | $25,920 |
| 69 | 116% | $2,320 | $27,840 |
| 70 | 124% | $2,480 | $29,760 |
How the numbers work
Claiming before full retirement age
Social Security reduces your benefit by 5/9 of one percent for each of the first 36 months you claim before full retirement age, and by 5/12 of one percent for every month beyond that. With a full retirement age of 67, claiming at 62 is 60 months early: 36 months at 5/9% (20%) plus 24 months at 5/12% (10%) is a 30% reduction. The example record's $2,000 becomes $1,400.
Waiting past full retirement age
Each month you delay after full retirement age earns a delayed retirement credit of 2/3 of one percent, which is 8% a year. Credits stop at 70, so there is no reason to wait past it. Three years of waiting turns the example record's $2,000 into $2,480, a 24% larger check for life.
What break-even means
Claiming earlier puts money in your pocket sooner; claiming later pays more every month once it starts. The break-even age is where the two cumulative totals cross. Live past it and the later claim paid more in total; die before it and the earlier claim did. It is a useful frame, not a verdict, because it ignores taxes, a spouse's benefit and what your survivor receives.
What this slider leaves out
One record, one person, no taxes. Your real decision also depends on whether you are still working (the earnings test can withhold benefits before full retirement age), how much of your benefit is taxable, Medicare premiums and IRMAA, a spouse's own record and spousal top-up, the survivor benefit your household keeps, and any pension from work that did not pay into Social Security. Those are the inputs the full analysis takes from your actual SSA statement.
Rules: SSA, Benefit reduction for early retirement and Delayed retirement credits. Dollar figures are an illustrative record, not a projection of your benefit.
Your full retirement age depends on your birth year
The slider uses 67, which is correct for anyone born in 1960 or later. If you were born earlier, your full retirement age is lower, so the same claiming age is fewer months early (a smaller reduction) or more months late (a larger credit). Claiming at 62 is still the earliest, and credits still stop at 70.
| Year of birth | Full retirement age | Reduction if you claim at 62 |
|---|---|---|
| 1943–1954 | 66 | 25% |
| 1955 | 66 and 2 months | 25.83% |
| 1956 | 66 and 4 months | 26.67% |
| 1957 | 66 and 6 months | 27.5% |
| 1958 | 66 and 8 months | 28.33% |
| 1959 | 66 and 10 months | 29.17% |
| 1960 and later | 67 | 30% |

Questions the slider raises
- Is the reduction for claiming early permanent?
- Yes. The percentage set at the month you start is the percentage you keep, and every cost-of-living adjustment afterwards is applied to that reduced amount. The one exception is the earnings test: months in which benefits were withheld because you were working are credited back when you reach full retirement age, which raises the check from that point on.
- Do I lose cost-of-living adjustments by waiting?
- No. Cost-of-living adjustments are applied to your benefit from age 62 whether or not you have started collecting. Someone who waits until 70 receives every adjustment announced in between on top of the delayed retirement credits.
- Is 70 always the best answer?
- No. Waiting pays the most per month and protects a surviving spouse, and it is the wrong call for someone with a short life expectancy, no other income to bridge the gap, or a spouse whose own record changes the math. The optimal age is the one that produces the most lifetime household income under your circumstances, which is why the full analysis runs on your actual earnings record rather than a rule of thumb.
- What happens if I claim before full retirement age and keep working?
- Social Security withholds $1 of benefits for every $2 you earn above the annual earnings limit in years before the year you reach full retirement age, and $1 for every $3 above a higher limit during the year you reach it. Only wages and self-employment income count; pensions, investment income and withdrawals do not. Starting the month you reach full retirement age, the limit disappears and the withheld months are credited back.
- How does my claiming age affect my spouse?
- Two ways. A spousal benefit tops a lower earner up to as much as half of the higher earner’s full retirement age amount, and it is reduced if the spouse claims it before their own full retirement age; it never grows past full retirement age, so delaying a spousal benefit past that point earns nothing. The survivor benefit is different: a widow or widower steps into the deceased’s actual benefit, including any delayed retirement credits, so the higher earner’s decision to wait sets the household’s income for the rest of the survivor’s life.
- Can I change my mind after I claim?
- Within 12 months of your first payment you can withdraw the application once, repay everything received, and start over later as if you had never claimed. After full retirement age you can instead suspend payments and earn delayed retirement credits until 70, then restart at the higher amount.
Run it on your real record
