Social Security At 62, 67 Or 70: The Break-Even
The break-even arithmetic is simple enough to do on a napkin, and it answers a narrower question than most people think. The survivor benefit is the part that changes the decision.

My mother-in-law decided to claim at 62 in a kitchen, in about four minutes, on the grounds that you never know. My father-in-law decided to wait until 70 in the same kitchen on the grounds that you never know. They were both right, and neither of them had run the numbers.
The numbers are not hard. What makes this decision feel impossible is that the arithmetic answers one question and the thing you are actually worried about is a different one.
The three levers
Social Security has a concept called full retirement age, the age at which you get your full calculated benefit with no reduction and no bonus. For people born in 1960 or later that age has been 67, and it is lower for people born earlier, so your own figure is on your statement.
You can start as early as 62, and the cheque is permanently reduced, because you will be collecting it for more months. You can delay past full retirement age up to 70, and the cheque is permanently increased for the same reason in reverse. There is no benefit to waiting past 70.
Permanently is doing real work in both of those sentences. The reduction or the increase applies for the rest of your life, and every future cost of living adjustment is calculated on the adjusted amount.
A worked example
Say your full benefit at 67 is $2,000 a month. Say claiming at 62 reduces that to $1,400, and waiting to 70 raises it to $2,480. Those are round numbers in the right neighbourhood for someone with a full retirement age of 67, and yours will differ.
The same benefit, three start dates
| Claim age | Monthly | Annual | Total collected by 80 | Total collected by 90 |
|---|---|---|---|---|
| 62 | $1,400 | $16,800 | $302,400 | $470,400 |
| 67 | $2,000 | $24,000 | $312,000 | $552,000 |
| 70 | $2,480 | $29,760 | $297,600 | $595,200 |
Illustrative amounts, before any cost of living adjustments and before tax. Totals assume the benefit starts on the birthday and runs continuously.
The break-even, three ways
Claiming at 62 against claiming at 67. By the time the 67 claimer starts, the 62 claimer has already collected sixty months of $1,400, which is $84,000. From then on the 67 claimer is ahead by $600 every month.
$84,000 divided by $600 is 140 months, which is eleven years and eight months, landing around age 78 years and 8 months.
Claiming at 67 against claiming at 70. The 67 claimer banks thirty-six months of $2,000, which is $72,000, and then falls behind by $480 a month. $72,000 divided by $480 is 150 months, twelve and a half years, so the crossover is at about 82 and a half.
Claiming at 62 against claiming at 70. Eight years of $1,400 is $134,400, and the monthly gap is $1,080. $134,400 divided by $1,080 is about 124 months, so the lines cross a little past 80.
Cumulative benefits collected, by claim age

Read that chart and the temptation is to decide based on how long you expect to live. That is the question the break-even answers, and it is the wrong one to build a plan around, because you get exactly one draw and no ability to check the result in advance.
The part nobody mentions
When one member of a married couple dies, the survivor does not keep both benefits. They generally keep the larger of the two, and the smaller one stops.
Run that through the example. If the higher earner claimed at 62 and locked in $1,400 a month, that $1,400 is what the surviving spouse lives on for however long they outlive them. If the higher earner waited until 70 and locked in $2,480, that is the floor instead.
$1,080 a month, for the rest of the survivor's life.
This reframes the decision entirely for a couple. The higher earner's claim age is not really a bet on their own lifespan. It is a bet on the longer of two lifespans, because the larger benefit survives both of them.
Household benefit rules have real detail to them, including conditions on when a survivor can claim and what happens if they claim early, so treat this as the shape of the thing and get your specifics from ssa.gov.
For a single person with no survivor to think about, the break-even arithmetic genuinely is most of the analysis.
The spousal side
A married person can claim on their own earnings record or on their spouse's, and they receive the larger of the two rather than both. The spousal benefit is a fraction of the higher earner's full retirement age amount, and it does not grow if the higher earner delays past their own full retirement age.
That last point catches people out. Delaying to 70 raises your own cheque and raises the survivor benefit, and it does nothing for what your spouse collects while you are both alive.
Conditions attach to all of it, including how long you have been married and whether the higher earner has claimed yet, and a divorced spouse can be eligible on an ex-spouse's record under certain rules. This is the corner of the system with the most fine print and the least reliable summaries. Take it from ssa.gov and nowhere else.
If you are still working
Claiming before your full retirement age while you are still earning triggers the earnings test. Above an annual earnings threshold, part of your benefit is withheld, and the threshold is reset every year.
The detail people miss is that withheld is not the same as lost. Once you reach full retirement age, your benefit is recalculated to credit back the months that were withheld, so the money comes back as a higher cheque rather than as a refund. The earnings test is closer to a deferral than a penalty.
Still, claiming at 62 while working full time is usually the worst of both. You accept the permanent reduction and then have part of the reduced cheque held back anyway.
What delaying actually costs
Waiting from 67 to 70 in the example means turning down $24,000 a year for three years, so $72,000 you have to find somewhere else.
For most people that comes out of a retirement account, which makes delaying a trade rather than a gift: spend down your own portfolio in your late sixties in exchange for a larger guaranteed cheque for the rest of your life. Whether that is a good trade depends on what the portfolio would have earned and on how long you live, and it has one property that nothing else in your finances has.
The cheque cannot run out.
Cost of living adjustments are calculated as a percentage of whatever your benefit is, so they compound on the bigger number. A 2.5% adjustment on $2,480 is $62 a month. The same adjustment on $1,400 is $35.
Across twenty years of adjustments that difference widens rather than closing.
Tax, briefly
Social Security benefits can be partly taxable depending on your other income. The calculation uses a measure that combines your adjusted gross income, any tax-exempt interest and half your benefits, and compares it to thresholds written into statute.
Those thresholds are the reason this catches people out. They are fixed dollar amounts that are not adjusted for inflation the way brackets are, so over time more people cross them.
If you are drawing from a traditional IRA or working part time, that income can pull a portion of your benefit into taxable territory. The IRS and ssa.gov both publish the current calculation.
If you change your mind
Two mechanisms exist and both are narrow. Within a short window after benefits start, generally twelve months, you can withdraw the application entirely, pay back everything you have received, and claim again later as though you never did. It is a once in a lifetime option.
Separately, once you reach full retirement age you can ask to suspend the benefit, which stops the payments and lets delayed credits accrue until you restart or hit 70. Suspending can also stop benefits other people are collecting on your record, which is not obvious from the name.
Both have conditions that change, and neither is a substitute for getting it right the first time. Ask the agency directly before relying on either one.
What actually decides it
Three things, in this order.
Whether you have other money to live on between 62 and 70, because delaying is only possible if something else pays the bills. Whether you are the higher earner in a couple, because your claim age sets the survivor floor. And your honest read on your own health.
Notice that the break-even age is not on that list. It is useful for understanding the trade and close to useless as a decision rule.
Go to ssa.gov and pull your statement. It takes ten minutes to set up an account and it gives you your actual full retirement age, your actual benefit at 62, at full retirement age and at 70, and the earnings record those figures were calculated from. Check the earnings record while you are there, because a missing year is a permanently smaller cheque and it is fixable.
