Why Social Security Spousal Benefits Top Out at Half of a Partner’s Full Retirement Benefit

Applying for Social Security spousal benefits works under a separate set of rules from filing on your own earnings record, and missing one important deadline can permanently reduce the money you receive.

Choosing when to start Social Security is one of the biggest retirement decisions many people face. If you wait until full retirement age, or FRA, your monthly check is payable without a reduction. For people born in 1960 or later, FRA is 67. Still, there are other ages to consider when deciding to claim.

The picture changes if you are filing for spousal benefits. In that case, you have fewer claiming options than you would if you were collecting based on your own work record.

Spousal benefits have a built-in limit

When Social Security is based on your own earnings, claiming before FRA leads to reduced monthly payments, while delaying beyond FRA can increase them.

For every year you delay past FRA, your benefit rises by 8%, up to age 70. If your FRA is 67, that can mean a boost of as much as 24%.

Spousal benefits do not work that way. Delaying a spousal claim beyond FRA does not add extra credits, so waiting longer does not improve the amount you receive.

If you claim before reaching FRA, your spousal benefit is reduced. Once you reach FRA, there is generally no advantage to waiting because these benefits do not earn delayed retirement credits.

The highest spousal benefit equals 50% of your spouse’s FRA benefit. For example, if your spouse’s FRA benefit is $2,000 per month, their payment may rise to $2,480 a month if they delay claiming until age 70.

Even so, your own spousal benefit would still be capped at $1,000 per month. Waiting until 70 would not increase that amount, since filing later does not raise the spousal benefit the way it can raise a worker benefit.

Social Security also pays retroactively for only up to six months. If you wait too long to file for spousal benefits, you could lose benefits you otherwise would have received.

Your payment can still rise over time

Like regular retirement benefits, Social Security spousal benefits are adjusted each year for cost of living.

So if your monthly spousal benefit starts at $1,000, annual increases can help it keep up with inflation. That is different from increasing the benefit by delaying your application, which does not apply here.

Know the rules before you file

Social Security is a complicated program, and the rules for spousal benefits can be especially confusing.

That is why it helps to review the program well before retirement. Knowing the details can give you a better sense of when to file and what monthly amount to expect.
