Social Security Spousal Benefits: A Two-Earner Couple Example, explained

In summary

This is part 2 of 2 of our guide to Social Security Beyond the Basics. It picks up where Social Security Spousal and Survivor Benefits Explained leaves off, and it is written to stand on its own: the key ideas are restated where you need them.

Alex’s PIA is $3,000; Sam’s is $1,000. Both have an FRA of 67. These are illustrative figures in today’s dollars.

Same couple as above: Alex’s PIA $3,000, Sam’s $1,000, both the same age with a full retirement age of 67, neither working after 62. Amounts are monthly, in today’s dollars; lifetime totals are monthly benefit × months received, before tax, with no discounting.

For example, Plan 3 with Alex dying at 78 and Sam at 92: $700 × 96 months (62–69) + $4,920 × 96 (70–77) + $3,720 × 168 (78–91) = $67,200 + $472,320 + $624,960 = $1,164,480.

The flip point is the second death, not the first. With Alex dying at 78, Plan 3 overtakes Plan 1 once Sam passes 82.1 and Plan 2 once Sam passes 84.3. If both die at the same age, Plan 3 overtakes Plan 1 at 80.8 and Plan 2 at 88.8. Under the 2023 period life table, for a 62-year-old man and woman the chance that at least one reaches 85 is 1 − (1 − 0.430) × (1 − 0.551) ≈ 74%. The delay is a bet on the longer of two lives, which is why Shoven and Slavov (10.3) found delay most consistently valuable for married primary earners.

For a married couple, the higher earner’s benefit is the household’s main beam; the smaller benefit is scaffolding that comes down when the first spouse dies. Delaying the higher earner’s claim is building the beam thicker — it carries the house through both lives, not just one.

Couples usually decide claiming ages one person at a time, but the decision that matters most is joint: the lower earner can often claim earlier with little cost, while the higher earner’s delay protects whichever spouse lives longer. Because the tax thresholds are frozen in nominal dollars, planning withdrawals from traditional accounts (10.5: Sequencing Withdrawals in Retirement) around them can change how much of each benefit is taxed.

If you are married, the higher earner’s PIA is clearly the larger (enough that the lower earner would receive a spousal top-up or a meaningfully bigger survivor benefit), and either spouse is in average or better health, then the higher earner delays toward 70 and the lower earner claims their own benefit when the household needs it, from 62 to full retirement age. The higher benefit continues to whichever spouse lives longer; the lower one stops at the first death. It assumes savings or work can cover spending during the delay and that the couple’s longer-lived member is likely to pass the mid-80s flip point (74% for a 62-year-old man and woman). Ignore it when both spouses have serious health conditions that shorten life expectancy, when the two PIAs are close, or when bridging the delay would require high-interest debt or selling investments in a crash.

The higher earner claiming early as if the decision were only their own. In the Alex and Sam example, claiming at 62 instead of 70 leaves Sam, as a widow or widower, $2,475 a month instead of $3,720: $1,245 a month, $1,245 × 12 = $14,940 a year, for the rest of Sam’s life. Ten years of widowhood makes that $149,400 in today’s dollars, falling on the person who will be living on one check. How to avoid it: make the higher earner’s claim a joint decision, base it on the life expectancy of the younger or healthier spouse, and look at both spouses’ estimates in their my Social Security accounts before either files.

Up to 50% of the worker’s full-retirement-age benefit (PIA), claimed at the spouse’s own full retirement age. Any benefit on the spouse’s own record is paid first, with a top-up to reach that 50%. Claiming at 62 cuts it to 32.5% of the worker’s PIA, and it does not grow past full retirement age.

No, not as two full checks. Social Security pays your own benefit and adds only the difference needed to reach the spousal amount, so the total equals the larger of the two. If your own PIA is half your spouse’s or more, the spousal benefit adds nothing.
