Social Security Break-Even Calculator: Is Waiting Worth It?
Your Social Security break-even age is the age at which the bigger checks from starting later make up for the checks you gave up by waiting. Before cost-of-living increases, starting at 67 instead of 62 breaks even at about 78 and 8 months, and starting at 70 instead of 62 at about 80 and 5 months. Live past that age and waiting pays more in total; die before it and starting earlier does.

Social Security break-even calculator
Compares any two starting ages from 62 to 70 using Social Security’s reduction and delayed-credit rules.
Break-even ages for common choices
With a full retirement age of 67, for anyone born in 1960 or later:
| Compare | No cost-of-living increase | With 2.5% yearly increases | If early checks earn 2% above inflation |
|---|---|---|---|
| 62 vs 65 | 77 and 8 months | 75 and 8 months | 80 and 1 month |
| 62 vs 67 | 78 and 8 months | 76 and 9 months | 81 and 1 month |
| 65 vs 67 | 80 and 1 month | 78 and 1 month | 82 and 5 months |
| 62 vs 70 | 80 and 5 months | 78 and 6 months | 82 and 9 months |
| 66 vs 70 | 82 and 3 months | 80 and 3 months | 84 and 8 months |
| 67 vs 70 | 82 and 6 months | 80 and 7 months | 84 and 11 months |

The ages are the same for any benefit amount, because each starting age pays a fixed percentage of your full benefit. They assume you start on your birthday month; most people can’t start until the month after turning 62, which shifts the 62 column by a month.
How the calculator works
It uses Social Security’s early retirement reduction: 5/9 of 1% for each of the first 36 months before your full retirement age and 5/12 of 1% for each month beyond that. Starting at 62 pays 70% of your full benefit if your full retirement age is 67. After full retirement age, it adds delayed retirement credits of 2/3 of 1% a month, 8% a year, until 70.
From each starting month, it adds up the monthly checks for both choices and finds the first month when the later start’s running total catches the earlier one. Your year of birth sets your full retirement age, and you can pick starting ages in months, not just whole years.
Your full benefit at full retirement age is on your Social Security Statement in your my Social Security account. Someone who earned a steady $50,000 a year has a full benefit of about $2,079, and other salaries range from about $1,279 at $20,000 to $3,938 at $150,000.
What moves your break-even age
- Cost-of-living increases move it earlier. Every check grows with the yearly increase, and because the later start collects its larger checks in later, higher-COLA years, it catches up sooner. With 2.5% a year, waiting from 62 to 67 breaks even about two years earlier.
- Investing the early checks moves it later. Because benefits rise with inflation, the fair comparison is a return above inflation, such as the yield on inflation-protected Treasury bonds. At 2% above inflation, waiting from 62 to 67 pays off at about 81 instead of 78 and 8 months. Entering a full market return with no cost-of-living increase mixes inflation-adjusted benefits with unadjusted returns and pushes the age too far out. The same logic applies in reverse if waiting lets you leave savings invested.
- Taxes can move it either way. Up to 85% of benefits can be taxable, and the years between retiring and claiming can be a low-income window for Roth conversions or IRA withdrawals.
- Working longer can raise the benefit itself. If you keep working while you wait, a high-earning year can replace a low one in your 35-year record, so the later start may be worth more than the estimate shows.
- A trust fund shortfall moves it later. The 2026 Trustees Report projects that the retirement trust fund can pay full benefits until the fourth quarter of 2032 and about 78% after that if Congress doesn’t act. A cut would apply to everyone’s checks, early or late, but it takes more from the larger checks of people who waited: for someone born in 1964, it moves the 62 versus 67 break-even from 78 and 8 months to about 81 and 6 months.
- Working before full retirement age can hold back early benefits above the earnings limit, which makes starting early worth less.
When break-even isn’t the whole answer
Break-even compares totals for one person. Three claiming factors it leaves out often matter more:
- How long you’re likely to live. A 62-year-old man has about 20 more years on average and a 62-year-old woman about 23, past most break-even ages. Social Security’s life expectancy calculator gives the average for your birth date.
- A spouse who could outlive you. If you’re the higher earner, the survivor keeps your larger check, including delayed credits. Waiting protects the survivor benefit even if you personally die before your break-even age. A spouse’s own spousal benefit is different: it’s based on half of your full benefit whether you start early or late, and waiting past full retirement age doesn’t raise it.
- The risk of running short late in life. A bigger check that rises with inflation for as long as you live works like insurance; break-even treats it like an investment.
Examples
- A single person with a $2,000 full benefit who expects to live to 90: starting at 62 pays $1,400 a month, starting at 70 pays $2,480. Without cost-of-living increases, the totals to 90 are about $470,000 and $595,000, about $125,000 in favor of waiting.
- The same person in poor health who expects to live to 75: starting at 62 collects about $218,000 by 75, starting at 70 about $149,000, so starting early comes out about $69,000 ahead.
