Delayed Retirement Credits
Published: 2/18/2026
If you've ever wondered whether it's worth waiting to claim Social Security, Delayed Retirement Credits (DRCs) are the core mechanism behind that decision. For every month you delay claiming past your Full Retirement Age (FRA), your monthly benefit permanently increases. Wait from 67 to 70 and your check is 24% bigger, for life.
The rule itself is simple: your benefit grows by 2/3 of 1% for every month you wait, or 8% per year. But there are a few details worth understanding, especially around spousal and survivor benefits.
What Are Delayed Retirement Credits?
When you reach Full Retirement Age, you are entitled to 100% of your Primary Insurance Amount (PIA). If you claim before FRA, your benefit is permanently reduced. If you claim after FRA, your benefit is permanently increased through Delayed Retirement Credits.
The credit rate is 2/3 of 1% per month, which equals exactly 8% per year. This rate applies to everyone born in 1943 or later. People born before 1943 had lower credit rates of 3% to 7% per year, but that cohort is now past age 82 and largely retired.
DRCs accumulate from the month after your FRA birthday month until the earlier of: the month you claim benefits, or the month you turn 70. Claiming after 70 provides no additional increase.
How Much Can DRCs Increase Your Benefit?
The size of the maximum possible increase depends on your birth year, which determines your FRA. A later FRA means fewer years available to earn DRCs before age 70.
| Birth Year | Full Retirement Age | Max Delay Window | Max DRC Increase |
|---|---|---|---|
| 1943–1954 | 66 | 4 years | 32% |
| 1955 | 66 + 2 months | 3 years 10 months | ~30.7% |
| 1956 | 66 + 4 months | 3 years 8 months | ~29.3% |
| 1957 | 66 + 6 months | 3 years 6 months | 28% |
| 1958 | 66 + 8 months | 3 years 4 months | ~26.7% |
| 1959 | 66 + 10 months | 3 years 2 months | ~25.3% |
| 1960 and later | 67 | 3 years | 24% |
Month-by-Month Calculation
Because DRCs are calculated monthly (not annually), delaying even a partial year earns proportional credit.
Example: James, Born in 1960
- FRA: 67 (January 2027)
- PIA: $2,000/month
- Decides to claim at age 69 and 6 months (July 2029)
- Months of delay past FRA: 30 months
- DRC rate: 30 × (2/3 of 1%) = 30 × 0.6667% = 20%
- Benefit at claim: $2,000 × 1.20 = $2,400/month
Had James waited 6 more months to age 70 (January 2030), he would earn the full 36-month credit: $2,000 × 1.24 = $2,480/month.
Who Earns Delayed Retirement Credits?
DRCs apply only to your own worker benefit, the retirement benefit calculated from your own earnings record. If you collect a spousal benefit based on your spouse's work record, that benefit is capped at 50% of your spouse's PIA no matter how old you are. Your own DRCs have no effect on it. Disability benefits are similar: SSDI converts to a retirement benefit at FRA, and there is no option to delay SSDI to earn DRCs.
What if you're eligible for both your own worker benefit and a spousal benefit? SSA pays your own benefit first. Your DRCs do increase your worker benefit, which may reduce or eliminate the spousal top-up.
DRCs and Survivor Benefits
There's a second reason to delay that many people miss: survivor benefits. When you die, your surviving spouse can receive up to 100% of what you were actually receiving, including the delayed credits.
Example: Survivor Benefit Impact
Maria (FRA 67, PIA $3,000) is considering when to claim. Her husband David has a much lower benefit.
- If Maria claims at FRA (67): David's survivor benefit = $3,000/month
- If Maria claims at 70: David's survivor benefit = $3,720/month (24% higher)
- Over 20 years of David's survivorship, the difference = $172,800 in additional lifetime income
If one of you earned a lot more than the other, delaying the higher earner's benefit protects whichever of you lives longer. That's worth more than the breakeven math alone suggests.

DRCs and Cost-of-Living Adjustments (COLA)
Social Security benefits receive annual Cost-of-Living Adjustments (COLA) to keep pace with inflation. COLA applies to your entire benefit amount, including the portion added by DRCs.
Why does this matter? Because COLA is a percentage, a bigger benefit grows by more dollars each year. The gap between claiming at 67 and 70 actually widens over time. A $2,480 benefit at 70 versus $2,000 at 67 starts with a $480 monthly gap. After 10 years of 2.5% COLA, that gap grows to roughly $615.
For more on how COLA works, see our guide on inflation and Social Security benefits.
The Delayed January Bump
There is a subtle nuance to how DRCs are applied. If you claim benefits between February and December of a year, a portion of your DRCs for that year may not appear in your initial benefit check. They are delayed until January of the following year.
This is because SSA applies DRCs earned in a given year on a January basis. The practical effect is a small initial underpayment followed by a corrected higher amount in January. See our detailed guide on the delayed January bump for the full explanation.

Frequently Asked Questions
How much do Delayed Retirement Credits increase my benefit?
Delayed Retirement Credits increase your benefit by 2/3 of 1% for each month you delay past Full Retirement Age, which equals 8% per year. If your FRA is 67 and you wait until 70, your benefit increases by 24% above your PIA. If your FRA is 66, the maximum increase is 32% (4 years × 8%).
What is the last age at which I can earn Delayed Retirement Credits?
Delayed Retirement Credits stop accruing at age 70. There is no benefit to waiting past 70 — you should claim by then to avoid leaving money on the table.
Do Delayed Retirement Credits apply to spousal benefits?
No. If you claim a spousal benefit on your spouse's record, your benefit is based on your spouse's PIA and is not increased by your own DRCs. However, if your spouse delays claiming their own benefit, that delay does increase your spousal benefit because it's calculated from their higher benefit amount.
Does my surviving spouse receive my Delayed Retirement Credits?
Yes. If you die before your spouse, your surviving spouse's benefit is based on the amount you were actually receiving (or were entitled to receive), which includes your DRCs. This is one of the strongest reasons high earners should consider delaying — it provides a larger survivor benefit for a lower-earning spouse.
What happens to withheld benefits from the earnings test — are they returned as DRCs?
Yes. If benefits are withheld before FRA because you exceeded the earnings test limit, SSA credits you for those withheld months when you reach FRA. Your benefit is recalculated as if you had claimed later, effectively restoring those credits through a higher monthly payment.
