How to use the Spousal Social Security Benefits Calculator
Enter your birth year and your own PIA (0 if you never worked under Social Security).
Pick the age you plan to claim.
Enter your partner's birth year, PIA and claiming age.
Optionally add a hypothetical age at death for your partner to see a survivor benefit estimate.
Read your total benefit, the spousal top-up and the table of every claiming age.
How the spousal benefit is calculated
Social Security pays a spouse their own retirement benefit first. If half of the worker's primary insurance amount (PIA) is larger than the spouse's own PIA, it adds a spousal top-up equal to the difference.
Excess = 50% × worker's PIA − spouse's own PIA Total = own benefit (with its early or delayed adjustment) + excess × spousal reduction factor
Example: your PIA is $700 and your partner's is $2,400. Half of $2,400 is $1,200, so the excess is $500. Claiming at your full retirement age you get $700 + $500 = $1,200. Claiming at 62 with a full retirement age of 67, your own benefit falls to 70% ($490) and the top-up to 65% ($325), for $815 a month.
Reduction for starting before full retirement age
Spousal benefits are reduced more steeply than retirement benefits. These figures assume a full retirement age of 67 (born 1960 or later).

Survivor percentages assume a survivor full retirement age of 67; for survivors born 1957–1961 it is between 66 and 67, which changes the early-start figures slightly.
Tips for married couples
The higher earner's claiming age matters twice. Their delayed credits raise their own check and the survivor benefit the other spouse may later receive.
The lower earner gains nothing past full retirement age on the spousal portion, though their own portion still grows with delayed credits.
Divorced spouses married at least 10 years and currently unmarried can use the same rules on an ex-spouse's record.

Frequently asked questions
How much is the Social Security spousal benefit?
At your full retirement age the spousal benefit can be up to 50% of your spouse's primary insurance amount (PIA). If you also have your own benefit, Social Security pays your own benefit first and adds only the difference between half your spouse's PIA and your own PIA.
How is the spousal benefit reduced if I claim early?
The spousal portion is reduced by 25/36 of 1% for each of the first 36 months before your full retirement age and 5/12 of 1% for each additional month. With a full retirement age of 67, starting at 62 pays 32.5% of the spouse's PIA instead of 50%.
Does the spousal benefit grow if I wait past full retirement age?
No. Delayed retirement credits apply to your own benefit only. The spousal portion reaches its maximum at your full retirement age, so waiting longer adds nothing to it.
Can I get spousal benefits before my spouse files?
Generally no. Your spouse must have filed for their own retirement benefit. The calculator starts the top-up at the later of your claim date and your partner's filing date. A divorced spouse married at least 10 years can claim independently if the ex-spouse is at least 62.
What is deemed filing?
For anyone born on or after January 2, 1954, applying for either your own or your spousal benefit counts as applying for both. You cannot take only the spousal benefit and let your own grow, so the reduction applies to both parts based on when you start.
How is the survivor benefit different?
A surviving spouse can receive up to 100% of what the deceased worker was receiving (including any delayed credits), or 100% of their PIA if they had not claimed. Starting survivor benefits as early as 60 reduces them, down to 71.5%. If the worker claimed early, the survivor still gets at least 82.5% of the PIA.
Is this the official amount?
No. It is an estimate using SSA's published reduction formulas and your PIAs. Rounding, exact birth dates, government pensions and the earnings test can change the final figure; check my Social Security at ssa.gov for official numbers.
