Social Security Delayed Retirement Credits
Every year you wait past 67 adds about 8% to your check, up to a 24% bonus at 70.
At a glance
How the Credits Work
For each year you delay claiming past full retirement age (67 in this model), your benefit grows by about 8% per year, until age 70. That is two-thirds of 1% for every month of delay — a guaranteed, inflation-adjusted raise that is hard to match anywhere else.

The Growth in Dollars
For a full benefit (PIA) of $2,000 per month:
| Claiming age | Credit earned | Monthly benefit |
|---|---|---|
| 67 | None | $2,000 |
| 68 | 8% | $2,160 |
| 69 | 16% | $2,320 |
| 70 | 24% | $2,480 |
Waiting From 62 vs 70
Combine delayed credits with early-claiming reductions and the spread widens: claiming at 62 pays $1,400 (70% of $2,000), while waiting until 70 pays $2,480 — a 77% larger check. Past roughly age 82, the delayed claim wins on cumulative lifetime dollars, and the advantage grows every year after.
When Delaying Makes Sense
Delaying is most valuable if you expect to live into your 80s, you are still working and do not need the income, or you want to maximize a surviving spouse's benefit, which inherits your delayed amount. Enter your AIME and a retirement age of 68, 69, or 70 in the calculator above — it reports the exact credit percentage and the boosted monthly benefit.
Frequently Asked Questions
Do credits accrue past age 70?
No. Delayed retirement credits stop at 70, so there is no financial reason to claim later than that.
Are the credits exactly 8% per year?
For anyone born in 1943 or later, yes — two-thirds of 1% per month, which compounds to about 8% annually in simple terms.
Do delayed credits apply to spousal benefits?
No. Spousal benefits do not earn delayed retirement credits beyond full retirement age.
What if I claim mid-year?
Credits accrue monthly, so claiming at 68 and 6 months earns roughly a 12% boost rather than waiting for the full year.
