How It Works

Couples planning when to claim Social Security can use this tool to estimate their combined benefits, spousal benefits included. Those numbers shape household retirement income and inform the timing of each claim. With the average monthly benefit for retired workers projected near $1,980 in 2026, claiming spousal benefits at the right moment can add real strength to a couple's finances.

The estimates follow the Social Security Administration's own formulas for the primary insurance amount (PIA) and for spousal benefits. Each spouse's full retirement age (FRA), earnings history as captured by their PIA, and chosen claiming ages all feed the result. The spousal benefit itself runs up to 50% of the higher earner's PIA, then adjusts for early claiming or for delayed retirement credits.

Claiming too soon ranks among the costliest missteps, since an early claim permanently shrinks benefits for both partners, spousal amount and all. Note too that spousal benefits generally open up only once the higher-earning spouse has filed for their own. The figures here also assume you've earned enough work credits to qualify for Social Security in the first place.

Example: The Smith Couple's Optimal Strategy

  1. 1 John, born in 1960, has a Full Retirement Age (FRA) of 67 and a Primary Insurance Amount (PIA) of $2,800. Jane, also born in 1960, has an FRA of 67 and a PIA of $1,200.
  2. 2 We calculate various claiming scenarios: John claims at 67, Jane claims at 67; John claims at 70, Jane claims at 67 (on her own or spousal); John claims at 67, Jane claims at 70 (spousal).
  3. 3 If John claims at age 70 ($3,500 monthly) and Jane claims her spousal benefit at age 67 ($1,400 monthly, 50% of John's FRA benefit), their combined monthly benefit is $4,900. If Jane claimed her own benefit at 67, it would be $1,200, resulting in a lower combined total.
  4. 4 This example demonstrates how delaying the higher earner's claim can unlock higher spousal benefits for the lower earner, leading to a greater overall household income. It highlights the importance of analyzing different claiming ages for both individuals to find the optimal strategy for their specific situation.

Frequently Asked Questions

How much is the Social Security spousal benefit?
The maximum spousal benefit is 50% of the higher earner primary insurance amount (PIA) at full retirement age. If you claim spousal benefits before full retirement age, the amount is permanently reduced. Your own benefit must be less than 50% of your spouse PIA for the spousal benefit to apply.
Can I collect spousal benefits and my own Social Security?
You cannot collect both in full. If you qualify for your own benefit and a spousal benefit, the SSA pays your own benefit first. If the spousal benefit would be higher, you receive a top-up to the spousal amount. You automatically get the higher of the two.
When should a married couple claim Social Security?
The optimal strategy depends on age difference, earnings history, and life expectancy. Often, the higher earner should delay to 70 to maximize the survivor benefit, while the lower earner claims at full retirement age or earlier. This maximizes combined lifetime benefits.
