How delayed retirement credits work
Once you pass your full retirement age, every month you do not collect a retirement benefit earns a credit of 2/3 of 1% of your primary insurance amount (PIA). Twelve months make 8%. The credits are simple, not compounded: three years of delay from 67 adds 24%, not about 26%. They stop the month you reach 70, so there is nothing to gain by waiting longer.
You earn credits either by not filing or, if you have already started benefits, by asking SSA to suspend them. Voluntary suspension is available from full retirement age to 70, and payments restart automatically at 70. While your benefit is suspended, anyone paid on your record, such as a spouse, is paused too, although a divorced spouse keeps receiving benefits.
The credits are figured on a PIA that has already received every cost-of-living adjustment since the year you turned 62, so delaying does not forfeit COLAs.
How much the credits add, by birth year
Because full retirement age rose from 66 to 67 while the credit rate stayed at 8% a year, younger workers have fewer months in which to earn credits. Their maximum at 70 is lower as a share of PIA. Someone born in 1954 could reach 132% by waiting from 66 to 70; anyone born in 1960 or later tops out at 124%, as the table shows.
The 8% rate is itself the end of a long phase-in. The Social Security Amendments of 1983 raised the credit in steps, from 3% a year for workers reaching full retirement age before 1990 to 8% for those reaching it after 2008. SSA’s current table starts at 5.5% for people born in 1933–1934 and reaches 8% for births in 1943 or later.
At the top of the earnings scale, SSA’s own examples show what waiting is worth. The largest possible benefit for someone retiring at 70 in January 2026 was $5,181 a month, against $4,152 for a worker retiring at full retirement age.
When the credits show up in your check
Credits do not always appear in your first payment. If you start benefits before 70, the credits earned in the calendar year you claim are added the following January. Suppose your full retirement age of 67 falls in June and you claim at your 69th birthday: your first check includes credits from full retirement age through the end of the previous year, and the rest arrive in January. Only a claim at 70 gets every credit at once.
Retroactive claims can also erase credits. After full retirement age you may ask for up to six months of back benefits, but never for a month before full retirement age. Taking back pay moves your starting month earlier, so those months earn no credits and your ongoing benefit is permanently lower. That can suit someone in poor health who needs cash now, but it is a trade, not free money.
How delayed credits affect a spouse and a survivor
Delayed credits change your family’s benefits in two opposite ways.
A spousal benefit ignores them. While you are alive, your spouse’s maximum is 50% of your PIA, the amount at your full retirement age, not the larger delayed amount. Delay also postpones the spousal benefit itself, because a current spouse can collect on your record only after you file; a divorced spouse of at least two years need not wait.
A survivor benefit keeps them. If you die first, a widow or widower who claims at their own full retirement age can receive up to 100% of the benefit you were getting, delayed credits included. For the higher earner in a couple, waiting buys a larger check that lasts as long as either spouse lives, which is why the payoff is often judged against the second death rather than the first. After the year of the death, the survivor usually files taxes as a single person, with narrower brackets, a pattern known as the widow’s penalty, so a larger inflation-adjusted check can matter most in those years.
Is delaying worth it? Trade-offs and common mistakes
Each year of delay from 67 to 70 buys 8% of PIA in extra inflation-adjusted income for life. The price is the benefits you give up while waiting, usually replaced by withdrawals from savings, and nothing comes back if you die early without a surviving spouse. Whether the trade pays depends on how long you and a spouse live, what your savings would have earned and your taxes in both periods. The break-even age puts a number on the first of these, and longevity risk explains why many people value the larger check as insurance. Mistakes to avoid:
- Treating both spouses’ delays alike. Only the larger benefit continues after the first death, so the lower earner’s delay pays off only while both spouses live, and the higher earner’s as long as either does.
- Skipping Medicare. SSA advises signing up for Medicare at 65 even if you delay retirement benefits; late enrollment can cost more.
- Ignoring the bridge years. Drawing more from a portfolio while you wait adds sequence-of-returns risk early in retirement.
Illustrative numbers
A worker with a full retirement age of 67 who waits to 69 and 4 months
- PIA
- Primary insurance amount, including every COLA since the year you turned 62
- Months of delay
- Months from full retirement age until benefits start; at most 36 when FRA is 67
- 2/3 of 1%
- The monthly credit for anyone born in 1943 or later, 8% a year
Credits earned in the year you claim are added the following January unless you claim at 70.
PIA at 67$2,000 a month
Months of delay28
Credits: 28 × 2/3 of 1%18.67%
Monthly benefit once all credits apply$2,000 × 118.67% = $2,373
Benefit if they had waited to 70$2,000 × 124% = $2,480
Waiting 28 months adds about $373 a month for life at today’s prices, and a surviving spouse could inherit the larger check. The credits earned in the claim year arrive the following January. Holding out the last eight months to 70 would add another $107 a month.

Delayed credits in MoneyWhatIf
Set a Social Security card’s claiming age past full retirement age and MoneyWhatIf applies SSA’s delayed retirement credits month by month from your modeled birth year, stopping at 70, then carries the larger benefit forward with plan inflation. Try the later age as a What-If: the original plan is drawn dashed underneath, so you can compare the withdrawals in the waiting years with the larger checks later, including what a surviving spouse keeps. Strategy Lab can also test Social Security claiming ages among its moves.
Common questions
Delayed credits FAQs
Do delayed retirement credits compound?
No. Each month adds 2/3 of 1% of your primary insurance amount, so the credits build in a straight line: 8% after one year, 16% after two and 24% after three for someone whose full retirement age is 67. What does compound is the cost-of-living adjustment, which is applied each year to the whole benefit, credits included.
Do I miss cost-of-living adjustments if I delay Social Security?
No. Your PIA is raised by each COLA starting with the year you turn 62, whether or not you have filed, and delayed credits are applied on top of that adjusted amount. Someone who claims at 70 therefore gets every COLA since age 62 built into the first check, plus 24% in credits if their full retirement age is 67.
Can I earn delayed retirement credits after I have started benefits?
Yes, once you reach full retirement age. You can ask SSA, orally or in writing, to suspend your retirement benefit, and each suspended month earns a credit until 70, when payments restart automatically. Benefits others receive on your record, such as a current spouse’s, stop during the suspension, and Medicare Part B premiums must then be paid directly because they cannot be deducted from a suspended benefit.
How much more is Social Security at 70 than at 62?
With a full retirement age of 67, claiming at 70 pays 124% of your primary insurance amount and claiming at 62 pays 70%, so the age-70 check is about 77% larger, and COLAs raise both alike. On a $2,000 PIA that is $2,480 a month instead of $1,400. Only the step from 67 to 70 comes from delayed credits; the rest is the early-claiming reduction you avoid.
Is there any benefit to waiting past 70 to claim Social Security?
No. Delayed credits stop at 70, so the monthly amount is the same whether you claim at 70 or later, and SSA pays at most six months of retroactive benefits. Waiting a full year past 70 would therefore lose about six months of payments permanently. If you have not filed, apply ahead of time so benefits start with the month you turn 70.
