Updated July 28, 2026. Quick answer: They do not. A spousal benefit is computed as a share of your primary insurance amount — the figure your benefit is built from at full retirement age. Delayed retirement credits are added after that, to your own payment. They never pass into the spousal calculation. Delaying to 70 raises your check and leaves your spouse’s spousal benefit exactly where it was.
Where the credits attach, and where they do not
| Benefit | Do your delayed credits raise it? |
|---|---|
| Your own retirement benefit | Yes |
| Your spouse’s spousal benefit | No |
| Your surviving spouse’s benefit | Yes — and that is the whole argument for delaying |
This pair is the most commonly conflated thing in claiming advice. “Delay so your spouse gets more” is false for the spousal benefit and true for the survivor benefit. They are different benefits under different subsections and they treat your credits differently. Anyone stating one rule for both is wrong about one of them.
What delaying does buy while you are both alive
Your own larger check, and nothing else on your spouse’s side. If the household reason for delaying is to lift a spousal benefit, that reason does not survive contact with the arithmetic.
What the spousal benefit does depend on
Your primary insurance amount, and the age at which your spouse claims. A spousal benefit claimed before their own full retirement age is reduced — that reduction is theirs, driven by their timing, and nothing you do with your own claim changes it.
No dollar amounts appear on this page, deliberately. The earnings-test exempt amounts are wage-indexed under 42 U.S.C. §403(f)(8)(B), the benefit formula bend points reset every year under §415(i), and full retirement age is a schedule that varies by birth year under §416(l). Any figure printed in an article is wrong within a year. Take current figures from the Social Security Administration directly, and take your own numbers from your Social Security statement.
