  "description": "A spousal Social Security benefit lets you claim up to 50% of your spouse's primary insurance amount (PIA) if that's more than your own retirement benefit, even if you have little or no work history of your own. SSA automatically pays you the higher of your own benefit or the spousal benefit — you don't get both added together. The 50% maximum only applies if you claim spousal benefits at your own full retirement age; claiming earlier permanently reduces the percentage, down to about 32.5% at age 62. Unlike your own retirement benefit, spousal benefits get no bonus for waiting past your FRA, so there's no reason to delay past FRA solely for the spousal portion. This calculator compares your own estimated benefit against the spousal benefit derived from your spouse's PIA and shows which one SSA would actually pay, plus how early claiming reduces it.",
  "formula": "Spousal benefit at FRA = 50% × spouse's PIA; reduced ~8.3-25/36 of 1% per month claimed early; SSA pays greater of own benefit or spousal benefit.",

  "faq": [
    {
      "q": "Can I get my own benefit plus a spousal benefit added on top?",
      "a": "No. SSA pays whichever is higher — your own retirement benefit or the spousal benefit — never both stacked together. If your own benefit is $900 and the spousal benefit works out to $1,400, you receive $1,400 total, not $2,300."
    },
    {
      "q": "Does delaying past my full retirement age increase my spousal benefit?",
      "a": "No, and this trips people up constantly. Delayed retirement credits (the 8% per year bonus) only apply to your own worker benefit, not to a spousal benefit. The spousal benefit maxes out at 50% of the other spouse's PIA once you reach your own FRA, so there's no financial reason to wait past FRA if you're only collecting on a spouse's record."
    },
    {
      "q": "Do I need to be divorced or can I claim on a current spouse's record?",
      "a": "Both work. You can claim spousal benefits on a current spouse's record if married at least one year, or on an ex-spouse's record if the marriage lasted at least 10 years, you're currently unmarried, and both of you are at least 62 — your ex doesn't even need to have filed yet if divorced two or more years."
    },
    {
      "q": "What if my spouse hasn't started collecting yet?",
      "a": "If you're divorced and meet the 10-year, currently-unmarried, two-year-since-divorce criteria, you can claim on their record even if they haven't filed. If still married, your spouse generally must have filed for their own benefit before you can claim a spousal benefit on their record."
