If you wait to claim Social Security past your full retirement age, your monthly benefit grows. The mechanism that makes this happen is called Delayed Retirement Credits (DRCs), and they offer one of the most reliable returns available to most Americans — an automatic 8% annual increase, guaranteed by federal law, with no investment risk. For workers in good health with reasonable longevity, the math often favors waiting.
Quick answer: what DRCs are
Delayed Retirement Credits are the increase to your Social Security benefit that you earn for each month you delay claiming past your Full Retirement Age (FRA). They accumulate at a rate of 2/3 of 1 percent per month — or 8 percent per year — and continue until you reach age 70.
After 70, no more credits are earned. Whether you claim at 70, 71, or 75, the benefit amount is the same. The financially rational choice is to claim no later than your 70th birthday.
How the math works
Your full retirement age varies depending on your birth year. For anyone born in 1960 or later, FRA is 67. If you delay claiming from 67 to 70, you earn 36 months of credits at 2/3 of 1 percent each — a total of 24 percent on top of your full benefit.
A worker whose full benefit at FRA would be $2,000 per month would receive:
- At 62: approximately $1,400 (a 30% reduction from FRA)
- At 67 (FRA): $2,000
- At 70: $2,480 (a 24% increase from FRA)
The difference between claiming at 62 and claiming at 70 is roughly 77% — meaning the age-70 benefit is 77% larger than the age-62 benefit. Over a 25-year retirement, that compounds into a meaningful difference.
Cost-of-living adjustments still apply
A common misconception is that delaying claiming means missing out on cost-of-living adjustments (COLAs). It doesn’t. COLAs apply to your “primary insurance amount” from age 62 onward, regardless of when you claim. By the time you start collecting, your benefit reflects both the delayed retirement credits and all the COLA increases that occurred during the wait.
Who benefits most from delaying
Three categories generally come out ahead by waiting:
People in good health with normal or above-average life expectancy
The break-even age — the point where total lifetime benefits from delayed claiming equal total lifetime benefits from early claiming — is typically in the early to mid 80s. Anyone who lives past that point ends up with more total Social Security income from having delayed.
Married couples where the higher earner waits
When the higher-earning spouse delays, two benefits increase: their own monthly check, and the survivor benefit the surviving spouse may receive. Survivor benefits include the deceased’s delayed retirement credits. For couples where one spouse is likely to outlive the other by many years, this is one of the most powerful arguments for delaying.
Single people with longevity in their family history
Without a spouse to consider, the calculation is purely about your own expected lifespan. People with parents and grandparents who lived into their late 80s or beyond often benefit from waiting.
Who should not delay
Delaying isn’t universally the right choice. Reasons to claim earlier:
- Serious health issues: if your life expectancy is materially below average, claiming earlier captures more total benefit
- No other income source to live on: if you can’t cover essential expenses without claiming, the math changes
- Need for cash now: waiting requires having other resources or continuing to work
- Spousal benefit considerations: spousal benefits don’t earn delayed retirement credits, so a spouse claiming on a partner’s record gains nothing from waiting past their own FRA
Spousal benefits don’t earn DRCs
An important detail: while your own retirement benefit earns DRCs from delaying, spousal benefits do not. If you’re receiving a benefit based on your spouse’s record, your monthly amount maxes out at FRA — waiting longer doesn’t increase it. The same applies to ex-spouse spousal benefits.
Survivor benefits work differently — they include any DRCs the deceased earned. So a worker who delays past FRA permanently increases the survivor benefit available to their spouse if they pass first.
What if you can’t wait until 70?
Even partial delay helps. Each month of delay past FRA adds 2/3 of 1 percent to your benefit. Waiting from 67 to 68 adds 8% — permanently. Waiting from 67 to 69 adds 16%. The benefit doesn’t require waiting all the way to 70 to be meaningful.
Some workers split the difference: they claim part-way between FRA and 70 to balance the desire for a higher benefit with the need for current income.
Strategies that combine work and delay
Continuing to work past FRA serves two purposes. First, you don’t need to draw on Social Security yet, so the delayed credits keep accruing. Second, additional years of high earnings can replace lower earnings in the 35-year calculation that determines your benefit. After FRA, the earnings test no longer applies — you can earn any amount without reducing your Social Security check.
Common mistakes
- Claiming at 62 by default without running the numbers for delayed claiming.
- Continuing to delay past 70. No additional benefit is earned. Claim at 70 (or before) to start receiving the maximum.
- Forgetting about COLA accumulation. The benefit during the delay period grows with cost-of-living adjustments — you don’t lose them by waiting.
- Assuming spousal benefits also grow. They don’t. Only your own retirement benefit and the survivor benefit grow with DRCs.
- Treating “break-even age” as a stopping point. Break-even is just the point where total benefits become equal — the longer you live past it, the more delaying pays off.
What to do next
Log into your my Social Security account at ssa.gov and look at the projected benefits at age 62, FRA, and 70. The difference between the FRA and 70 figure is what delaying would gain you. If you’re in reasonable health, have other income to bridge the gap, and aren’t taking spousal benefits as your primary, delaying is often the highest-return decision available.
