Answer from Retirementradar

Social Security spousal benefits are typically calculated as up to half of the primary worker's full retirement-age benefit amount. The exact amount you receive depends on when you start claiming benefits and your own earnings history.

If you are eligible for a spousal benefit, it is generally equal to 50% of your spouse's primary insurance amount (PIA), which is based on their average indexed monthly earnings. However, if you claim benefits before your full retirement age, your spousal benefit will be permanently reduced. Social Security will always pay you your own earned benefit if it is higher than the spousal benefit you are eligible for.

You will typically need your own Social Security number, your spouse's Social Security number, and information about your respective earnings histories. Knowing your full retirement ages and current ages is also important for accurate estimates.
