Social Security Spousal Benefit Calculator
Estimate a spousal retirement benefit as a percentage of the worker’s full benefit, and see the top-up a lower-earning spouse may receive.
How it works
Spousal amount = worker PIA × rate (≤50%) · Total = max(own benefit, spousal amount) · Top-up = spousal amount − own benefit
A married person can claim on their own work record or on their spouse’s — Social Security effectively pays the larger of the two, not both. The spousal benefit is worth up to 50% of the higher earner’s full (primary insurance) amount when claimed at full retirement age; claiming earlier reduces it. If the lower earner already qualifies for their own benefit, the system pays that plus a top-up that brings them to the spousal level.
Worked example
If the higher earner’s full benefit is $2,400 and the spousal rate is 50%, the spousal amount is $1,200. A spouse with their own $900 benefit receives a $300 top-up, for $1,200 total a month.
Frequently asked questions
Can I collect my own benefit and a spousal benefit?
Not stacked. You receive your own benefit first, and if the spousal amount is higher you get a top-up to that level — the total equals the larger of the two, not the sum.
Is the spousal benefit always 50%?
Fifty percent is the maximum, available only if you claim at your full retirement age. Claiming earlier permanently reduces the spousal portion, and unlike a worker benefit it does not grow past full retirement age.
Does this reduce the worker’s own benefit?
No. A spousal benefit paid to your partner does not lower the amount the primary worker receives.
