The rule that makes this the most important decision in the system
When one spouse dies, the survivor does not keep both benefits. They keep the larger of the two. The smaller one disappears from the household permanently.
That single rule reshapes everything. If one of you had much higher earnings, the amount that spouse locks in is not just their own income — it is the floor under whichever of you lives longer, potentially for decades. This is why delaying the higher earner's claim to 70 is so often the right move even when the break-even arithmetic looks unconvincing. You are not buying a better return. You are buying insurance for the survivor.
The reverse is also true and less well known: the lower earner delaying rarely helps at all, because their benefit is likely to vanish anyway when the first death occurs. For many couples the efficient answer is the lower earner claims early and the higher earner waits.
How the survivor amount is calculated
At your own full retirement age, a survivor benefit equals 100% of what your late spouse was receiving or entitled to receive — including any delayed retirement credits they earned by waiting past their full retirement age. Claim earlier and it's reduced on a sliding scale down to 71.5% at age 60, the earliest possible age for a surviving spouse. If you are disabled, you can claim from 50 at that same 71.5%.
One limit catches people out. If your late spouse claimed their own benefit early, your survivor benefit is generally capped at the greater of what they were actually receiving or 82.5% of their primary insurance amount. Their early claim followed them, and it follows you.
There is no reason to delay a survivor benefit past your own full retirement age. Survivor benefits do not earn delayed retirement credits. Waiting to 68 or 70 gets you nothing extra on this benefit.
The switching strategy. Survivor benefits and your own retirement benefit are separate entitlements, and you can take them in either order. Many widows and widowers claim the reduced survivor benefit at 60 and let their own benefit grow untouched to 70, then switch. Others do the opposite. Whichever benefit is smaller now is usually the one to claim first.
Who qualifies
- A surviving spouse married at least nine months before the death, with exceptions for accidental death and military service
- A surviving divorced spouse, if the marriage lasted at least 10 years — and claiming this does not reduce anything for the late spouse's other family members
- A surviving spouse of any age caring for the deceased's child who is under 16 or disabled
- Remarriage after age 60 does not stop you claiming on a late spouse's record. Remarriage before 60 does.
Two practical warnings
You usually cannot apply online. Survivor claims generally require calling the SSA or visiting an office, and the funeral home often reports the death but does not file anything on your behalf.
Benefits are not prorated for the month of death. If your spouse dies in May, the payment that arrives in June is for May and typically has to be returned. There is also a one-time death payment of $255, which has not been raised since 1954.
