Social Security Spousal Benefit Calculator
A spouse can claim on their partner's record: up to half the higher earner's full benefit. You receive the greater of that or your own — never both stacked. Claiming before your full retirement age permanently reduces the spousal amount, and unlike your own, it never grows past full retirement age.

The spousal benefit tops up your own by $150.
Claiming the spousal benefit before your full retirement age locks in a permanent reduction — and unlike your own benefit, the spousal amount earns no delayed credits for waiting past full retirement age. There is no bonus for claiming spousal later than that, so the calculation is simply: reduced if early, capped at 50% if on time.

How this calculator works
The maximum spousal benefit is half the higher earner's full retirement benefit. Claiming before full retirement age reduces it by 25/36 of 1% per month for the first 36 months early and 5/12 of 1% for each month beyond. You receive the greater of the reduced spousal amount or your own benefit; the top-up is the difference when spousal is larger.
The higher earner's figure should be their benefit at full retirement age, not a reduced or delayed amount. Survivor benefits, which follow different and generally more generous rules, are not modelled, nor is the requirement that the higher earner has claimed. Full retirement age is 67 for those born in 1960 or later.
What this assumes
- The spousal benefit is up to half the worker's primary insurance amount at full retirement age, reduced if claimed earlier.
- It does not increase past full retirement age — unlike a worker's own benefit, delaying a spousal claim to 70 adds nothing.
- Divorce, survivor and government pension offset rules are not modelled and can change eligibility entirely.
What changes this number
- The higher earner's claiming age
- Drives both the spousal benefit and, more importantly, the survivor benefit that continues for life.
- Claiming before full retirement age
- Permanently reduces the spousal amount, and the reduction is steeper than many expect.
- Your own benefit
- You receive the larger of the two, not both — which is why a lower-earning spouse's own record can still matter.

Frequently asked questions
How does the Social Security spousal benefit work?
You can receive up to 50% of your spouse's full retirement benefit, or your own benefit, whichever is larger — not both added together. If your own benefit is more than half your spouse's, the spousal benefit adds nothing. If it is less, you are topped up to the spousal amount.
Can I get my benefit plus a spousal benefit?
No. Social Security pays the higher of the two, not the sum. In effect, if you are eligible for a spousal benefit larger than your own, you receive your own amount plus a top-up that brings the total to the spousal figure. It is one benefit, not two.
How much is the spousal benefit reduced for claiming early?
At full retirement age it is the full 50%. Claim earlier and it drops — by 25/36 of 1% a month for the first three years early, then 5/12 of 1% a month beyond that. At 62 with a full retirement age of 67, that is a 35% cut, leaving 32.5% of the worker's benefit rather than 50%.
Does the spousal benefit grow if I wait past full retirement age?
No. Unlike your own benefit, which earns delayed retirement credits worth about 8% a year until 70, the spousal benefit is capped at 50% and gains nothing for waiting past full retirement age. There is no reason to delay a spousal claim beyond then.
Can divorced spouses claim?
Yes, if the marriage lasted at least ten years, you are currently unmarried, and you are at least 62. A divorced-spouse benefit does not affect or require anything from your ex, and they need not have claimed if you have been divorced at least two years. The 50% rules are otherwise the same.
