Introduction
If you are married, you may be able to get Social Security benefits based on your spouse's work record. This is called a spousal benefit. It can help the lower-earning spouse in a household receive more money each month in retirement.
The spousal benefit can be up to half of your spouse's full retirement age benefit. But the exact amount you get depends on a few things: your own benefit, your spouse's benefit, and the age you start collecting. If you file before your full retirement age, your payment will be reduced. If you wait until your full retirement age, you get the full spousal amount. Filing after your full retirement age does not increase the spousal benefit further.
This Social Security Spousal Benefits Calculator shows you how much the lower-earning spouse could receive each month. Enter both spouses' birth years and estimated benefits at full retirement age, then pick the age the lower-earning spouse plans to file. The calculator will show your estimated monthly and annual benefit, a step-by-step breakdown of the math, and a comparison chart so you can see how filing at different ages changes your payment.
How to Use Our Social Security Spousal Benefits Calculator
Enter basic details about both spouses below to see how much the lower-earning spouse could receive each month and each year in combined Social Security benefits.
Higher-Earning Spouse Birth Year: Type the birth year of the spouse who earns more. This must be a four-digit year between 1924 and 1964. The calculator uses this to find their full retirement age. If you need help determining exact ages or date differences, our age calculator can help.
Higher-Earning Spouse Monthly Benefit at Full Retirement Age (PIA): Enter the higher earner's estimated monthly benefit at full retirement age. You can find this number on your Social Security Statement at SSA.gov, or use our Social Security calculator to estimate it.
Lower-Earning Spouse Birth Year: Type the birth year of the spouse who earns less. This must be a four-digit year between 1924 and 1964. The calculator uses this to find their full retirement age.
Lower-Earning Spouse Monthly Benefit at Full Retirement Age (PIA): Enter the lower earner's estimated monthly benefit at full retirement age. If this spouse has no work history, enter 0.
Intended Filing Age: Choose the age the lower-earning spouse plans to start collecting benefits. Pick a year between 62 and 70 and a number of months between 0 and 11. Keep in mind that spousal benefits do not grow past full retirement age. To figure out the best age to start collecting, our Social Security break-even calculator can help you compare the long-term value of filing earlier versus later.

What Are Social Security Spousal Benefits?
Social Security spousal benefits let a married person collect money based on their spouse's work record. If your spouse earned more than you, you may get up to half of their full retirement age benefit. This is on top of any benefit you earned from your own work. You do not take money away from your spouse — it is extra money paid to you by Social Security.
How Spousal Benefits Work
Social Security looks at two numbers: half of the higher earner's benefit and your own earned benefit. If half of your spouse's benefit is more than yours, you get the difference as a spousal top-up. If your own benefit is already equal to or higher than half of your spouse's, you do not receive any spousal benefit. You simply keep your own higher amount.
When you file matters. If you claim benefits before your full retirement age (FRA), your spousal benefit is reduced. The earlier you file, the bigger the reduction. Filing at age 62 gives you the smallest monthly payment. Filing at your FRA gives you the full spousal amount. Use our Social Security retirement calculator to explore how your own filing age affects your individual retirement benefit.
One important rule: spousal benefits do not grow after your full retirement age. Waiting past your FRA does not increase your spousal payment. Delayed retirement credits only apply to your own earned benefit, not the spousal portion.
What Is Full Retirement Age?
Full retirement age is the age when you can collect your full Social Security benefit with no reduction. It depends on the year you were born. For people born between 1943 and 1954, FRA is 66. For those born in 1960 or later, it is 67. Birth years in between have an FRA somewhere between 66 and 67.
What Is a PIA?
PIA stands for Primary Insurance Amount. It is the monthly benefit you would receive if you file at exactly your full retirement age. You can find your PIA on your Social Security Statement at SSA.gov.
Who Can Get Spousal Benefits?
To qualify for spousal benefits, you must be married to (or in some cases divorced from) someone who is eligible for Social Security. You must be at least 62 years old. If you are divorced, the marriage must have lasted at least 10 years, and you must be currently unmarried. Your ex-spouse must also be eligible for benefits.
How to Use This Calculator
Enter the birth year and estimated FRA benefit for each spouse. Then pick the age when the lower-earning spouse plans to file. The calculator shows the estimated monthly and annual benefit, a full breakdown of the math, and a comparison table for every filing age from 62 to 70. This helps you see how filing earlier or later changes your payment.
Keep in mind that this tool gives estimates only. Your actual benefit depends on your full earnings history, cost-of-living adjustments, and other factors. To understand how inflation may affect your benefits over time, try our inflation calculator.
