- You can start Social Security any month from age 62 to 70. The age you choose sets your benefit permanently, so this is one of the few retirement decisions you cannot undo.
- Claiming at 62 cuts your benefit about 30% for life. Waiting past full retirement age earns delayed retirement credits of roughly 8% a year up to 70, after which there is no further gain.
- Health and longevity, whether you are still working, and your marital status matter more than the breakeven math. A higher earner who is married is buying a survivor benefit for a spouse, not just a check for themselves.
The decision of when to claim Social Security is one of the largest financial choices most people make, and one of the least reversible. You can file any month between age 62 and age 70, and the month you choose sets your monthly benefit for the rest of your life. There is no do-over button. Once a benefit amount is locked in, it follows you, and it follows a surviving spouse, for decades.
This guide walks through how the numbers work, what the breakeven age really means, and the factors that should actually drive the decision. The goal is not to talk you into waiting or claiming early. It is to help you decide on the facts of your own situation rather than on a rule of thumb you heard at a dinner party. You can confirm your personal figures at ssa.gov.
The three ages that frame the decision
Three ages matter. The earliest is 62, the first month you can claim a retirement benefit. The anchor is your full retirement age, the age at which you receive 100% of the benefit your earnings record has earned. For anyone born in 1960 or later, full retirement age is 67. The latest age worth waiting for is 70, after which delaying gains you nothing more.
Between 62 and 67, claiming early permanently reduces your check. Between 67 and 70, delaying permanently increases it. The Social Security Administration explains these adjustments in its benefits by age materials.
The 30% haircut for claiming at 62
If your full retirement age is 67 and you claim the first month you are eligible at 62, your benefit is cut by about 30%. A benefit that would have been $2,000 a month at 67 becomes roughly $1,400 at 62.
That reduction is not a temporary discount that resets when you reach 67. It is permanent. The smaller check is what you receive every month for the rest of your life, adjusted only for the annual cost-of-living increase. It also lowers the survivor benefit a spouse can later receive based on your record, which is why an early claim by the higher earner echoes long after that person is gone.
Delayed retirement credits: roughly 8% a year to 70
Wait past full retirement age and the math runs the other way. Each year you delay claiming, you earn delayed retirement credits worth about 8% a year, accruing monthly, up to age 70. A benefit of $2,000 at 67 grows to roughly $2,480 at 70, a 24% increase, plus cost-of-living adjustments along the way.
The credits stop at 70. There is no benefit to filing at 71 or later, and you should never delay past 70 by accident. Seventy is the ceiling.
Claiming age and your approximate benefit
The table below shows roughly what share of your full benefit you receive at each claiming age, assuming a full retirement age of 67. Treat these as close approximations; the Social Security Administration calculates the exact figure month by month.
| Claiming age | Approximate % of full benefit |
|---|---|
| 62 | ~70% |
| 63 | ~75% |
| 64 | ~80% |
| 65 | ~87% |
| 66 | ~93% |
| 67 (full retirement age) | 100% |
| 68 | ~108% |
| 69 | ~116% |
| 70 | ~124% |
The span from earliest to latest is wide. The same earnings record can produce a benefit at 70 that is roughly 77% larger than the benefit at 62. That gap is the prize for waiting, and the price for claiming early.

The breakeven age, and why it is not the whole story
The breakeven age is the point at which the larger delayed checks have paid out as much total money as the smaller early checks would have by then. Claim early and you collect more checks, but each one is smaller. Wait and each check is bigger, but you collect fewer of them. Somewhere the cumulative totals cross.
For the 62-versus-70 decision, that crossover typically lands somewhere from the late 70s to the early 80s, depending on the exact figures and on whether you account for investment returns on early checks. If you live well past the breakeven age, waiting wins on lifetime dollars. If you do not reach it, claiming early wins.
Breakeven analysis answers one narrow question: which choice pays more total dollars if you die at a given age? It ignores survivor benefits, the value of guaranteed income late in life, taxes, and the simple reality that you cannot know your own lifespan. Use it to understand the trade, not to settle it.
The factors that should actually drive your decision
The breakeven calculation assumes you know how long you will live. You do not. So the better way to decide is to weigh the factors below against your own circumstances.
Health and longevity. If you have a serious health condition or a family history of short lifespans, claiming earlier is reasonable; you may not reach the breakeven age. If you are healthy and long-lived relatives are common, delaying buys you a larger guaranteed income for the years when your portfolio may be thinnest.
Whether you are still working. If you claim before full retirement age and keep working, the Social Security earnings test temporarily withholds part of your benefit once your wages pass an annual limit. The withheld amounts are credited back later, but the test is a strong reason not to claim early while still earning a meaningful paycheck.
Marital status and survivor benefits. This is the most underrated factor. When one spouse dies, the survivor keeps the larger of the two benefits. If the higher earner delays to 70, they are buying a larger survivor benefit for whichever spouse lives longer. For married couples, the higher earner's claiming age is often the single most important number in the whole plan.
Other income and your portfolio. If you have ample savings or a pension, you can afford to delay Social Security and let it grow, treating it as inflation-protected longevity insurance. If Social Security is most of your income and you have little else, claiming when you need the money is sensible.
Your tax bracket. Benefits can be partly taxable depending on your total income, and large required distributions or other income later can push more of your benefit into taxable territory. Coordinating the claiming age with your broader tax picture, including Medicare premium surcharges, can matter more than the benefit math alone.
Spousal and survivor strategy basics
Beyond your own record, two other benefit types shape the decision.
A spousal benefit can be worth up to 50% of the higher earner's full retirement age benefit. A lower-earning or non-working spouse may receive more from a spousal benefit than from their own record. Spousal benefits do not grow with delayed retirement credits, so there is no reason for the lower earner to delay a spousal benefit past full retirement age.
A survivor benefit is different and larger. A surviving spouse can step up to the deceased spouse's full benefit, including any delayed retirement credits the deceased earned. This is the mechanism that makes the higher earner's decision to delay so valuable: it raises the floor for the survivor's remaining years. The Social Security Administration details both in its survivors planner.
A scenario: two healthy 62-year-olds
Consider a married couple, both 62 and in good health. He is the higher earner with a full retirement age benefit of $2,800; she earned less, with a benefit of $1,400. The temptation is for both to claim now and start the cash flow.
A common alternative: she claims at her full retirement age to start some income, while he delays to 70. His benefit grows from $2,800 to roughly $3,470. If he dies first, which is statistically likely, she steps up to that larger survivor amount for the rest of her life instead of his reduced early figure. The couple gives up a few years of his checks in their 60s in exchange for a materially larger guaranteed income through her longest years. Whether that trade fits depends on their savings, their health, and their comfort with spending down other assets first.
The 2034 trust fund question, framed honestly
You will hear that Social Security is going broke. That is not accurate. The Social Security Administration's trustees project that the combined retirement trust funds could be depleted around 2034 to 2035. Depletion does not mean zero. Payroll taxes keep flowing in, and those taxes are projected to cover an estimated portion of scheduled benefits, in the neighborhood of 80%, even with no changes from Congress.
In practice, lawmakers have a long history of adjusting the program before such deadlines. The honest planning posture is to expect Social Security to be there, possibly with modest future changes, and not to claim early out of fear that the program will vanish. Fear is a poor reason to lock in a 30% lifetime reduction. You can read the program's own framing at ssa.gov.
Do not claim early simply because you are worried Social Security will disappear. Depletion projections describe a possible reduction to roughly 80% of scheduled benefits, not an elimination. Claiming at 62 to beat a phantom cutoff can cost you far more than any realistic future adjustment.
