When to claim Social Security: what the break-even age tells you
You can start Social Security retirement benefits as early as 62, but the monthly amount depends on when you start. The Social Security Administration (SSA) reduces the benefit for each month you claim before your full retirement age, and increases it for each month you wait past that age, up to age 70. The break-even age is a simple way to see the trade: claiming earlier pays you for more months, claiming later pays you more each month, and at some age the totals meet.
This calculator finds that age from two monthly amounts you type in. It does not work out your benefit. For that, the SSA says its Social Security Statement shows personalized estimates at nine different ages, and you can view it by creating an official my Social Security account. Use those estimates here, and keep in mind they are estimates.
How the benefit changes with claiming age
SSA publishes the rules. Full retirement age is 66 for people born in 1943 to 1954, rises by two months a year for 1955 to 1959, and is 67 for 1960 and later. Claiming at 62 cuts the benefit by 25% if your full retirement age is 66 and by 30% if it is 67. For people born in 1943 or later, each month of delay past full retirement age adds two thirds of 1%, which is 8% a year, until the increase stops at 70. Those are the SSA's published rules; your statement applies them to your own earnings record, which is why this page asks for your numbers instead of guessing.
The calculation
With an earlier claiming age E and a later age L, both counted in months, and benefits B_E and B_L, the earlier claim has already collected for L − E months when the later one begins. After k months of the later benefit, the totals are:
earlier total = BE × (L − E + k) later total = BL × k
The later claim catches up at the first k where B_L × k is at least B_E × (L − E + k). Without cost-of-living increases that is k = B_E × (L − E) ÷ (B_L − B_E), rounded up to a whole month. The age shown is your later claiming age plus k months, the point at which that k-th monthly payment has been received.
Worked example: 1,500 from 62 against 2,200 from 67
Suppose your statement shows 1,500 a month if you claim at 62 and 2,200 a month at 67. These are made-up figures for illustration. By the time the later benefit begins, claiming at 62 has already paid 90,000 over 60 months. The later benefit is 700 a month higher (46.7% more), so it closes the gap slowly. After 129 months of the later benefit, at age 77 years 9 months, the later claim has received 283,800 against 283,500. After that it stays ahead for as long as you collect.
Read across ages: by 75 claiming at 62 has received 234,000 and claiming at 67 has received 211,200, so the later claim is behind by 22,800; by 85 claiming at 62 has received 414,000 and claiming at 67 has received 475,200, so the later claim is ahead by 61,200; by 95 claiming at 62 has received 594,000 and claiming at 67 has received 739,200, so the later claim is ahead by 145,200.
How the gap between your two amounts changes the answer
| Benefit at 67 | Higher by | Catches up at age |
|---|---|---|
| 1,800 | 20% | 92 |
| 2,000 | 33% | 82 |
| 2,200 | 47% | 77 years 9 months |
| 2,600 | 73% | 73 years 10 months |
A small difference between the two estimates pushes break-even far into the future, and a large one pulls it in. If your later amount is only 1,800, the later claim does not catch up until 92. If it is 2,600, it catches up by 73 years 10 months. Because the answer is so sensitive to the two amounts, it is worth checking them on your statement rather than relying on rules of thumb.
Waiting until 70
Delaying to 70 stretches the head start even further. With 1,500 at 62 and 2,650 at 70, the earlier claim collects 144,000 before the later benefit begins, and the later claim catches up at age 80 years 6 months. Again, these are illustrative amounts.
Cost-of-living increases
Benefits can rise over time with cost-of-living adjustments. The optional increase box applies one yearly rate to both benefits, counted from the earlier claim age. With a 2.5% yearly increase the first example catches up at 76 years 1 month instead of 77 years 9 months. It raises both totals, so the head start and the amounts received at catch-up are larger too (94,614 against 90,000 for the head start). Leave it at 0 to compare in today's dollars.
What this calculator does not include
Break-even is a simplification. It treats the choice as a sum of payments and does not discount them, so a dollar received at 62 counts the same as a dollar at 85, although money received sooner can be invested or spent. It also ignores the effects on your spouse or survivors, income taxes on benefits, the earnings test if you keep working before full retirement age, and Medicare premiums. It cannot know how long you will live, and the question of whether to claim early is partly about risk: waiting is a form of insurance against a long life, while claiming earlier gives you money sooner. Because those items matter, treat the output as one input and not as advice, and consider talking to a fee-only adviser.
To see the bigger picture, the retirement planning calculator estimates how much you need to save, the pension lump sum vs monthly calculator compares a pension lump sum with monthly payments, and the inflation calculator shows how prices change buying power over the years you may be collecting.
Social Security claiming age questions
How do I find my break-even age for claiming Social Security?
Find the monthly benefit your statement shows at each age, and compare the totals received over time. In the example, 1,500 from 62 against 2,200 from 67 breaks even at age 77 years 9 months.
Where do I get my benefit estimates?
The SSA says its Social Security Statement shows personalized retirement benefit estimates at nine different ages, and that you can view it online by creating an official my Social Security account. Use those amounts for the two ages you want to compare.
Does this calculator use my Social Security number?
No. It never asks for one and does not look up your record. You type in two amounts, and everything is calculated in your browser.
Is the break-even age a prediction of how long I will live?
No. It only says at which age the totals meet. Whether you reach it is not something this page can tell you, and the right choice also depends on your health, your other income, taxes and your spouse.
Does the calculator include spousal or survivor benefits?
No. It compares two claiming ages for one person. Spousal and survivor rules can change the best choice, so look at them separately.
