Survivor Benefit Calculator: How to Use It
A widow or widower can collect Social Security on a late spouse's record and on their own, one at a time. Which one you take first, and when, can be worth tens of thousands of dollars.
What this calculator does
It compares up to four ways to claim: the survivor benefit now; your own benefit first (from 62 at the earliest) with a switch to the unreduced survivor benefit at your survivor full retirement age; the unreduced survivor benefit with a switch to your own at 70; and a reduced survivor benefit now with a switch to your own at 70. For each, it adds up the monthly checks from your current age through 85, month by month.
What each input means
Survivor's birth year and current age
Your birth year sets two different full retirement ages. Survivor benefits use their own schedule, which reaches 67 for people born in 1962 or later. Your own retirement benefit reaches 67 for people born in 1960 or later. The calculator uses the right one for each benefit. Social Security treats a January 1 birthday as the previous year, so if that's you, enter the year before.
Deceased's PIA
The primary insurance amount: what your spouse would have been paid at their own full retirement age, before any early-claiming cut or delayed credits. It's on their Social Security statement, or SSA can give it to you.
Had the deceased started Social Security?
This matters more than most people expect. If they claimed early, your benefit is capped at the larger of what they were receiving or 82.5% of their PIA. If they claimed after full retirement age, the higher amount they were receiving (with delayed credits) is your base. If they hadn't filed, enter their birth year and age at death; any months they waited past full retirement age, up to 70, add 2/3 of 1% each.
Survivor's own benefit at full retirement age
Your own PIA from your own work record. Enter 0 if you don't have one. The calculator reduces it for claiming before your full retirement age and raises it 8% a year for waiting past it, up to 70.
How the reductions work
Survivor benefits taken before your survivor full retirement age lose up to 28.5%, spread evenly across the months from 60 to that age. At 60 you get 71.5%. Your own retirement benefit loses 5/9 of 1% for each of the first 36 months early and 5/12 of 1% for each month beyond that, so claiming at 62 with a full retirement age of 67 leaves 70%.
Survivor benefits don't grow past your survivor full retirement age. Your own benefit does, until 70. That difference is why the switch strategies exist.
What the calculator leaves out
Totals aren't discounted or adjusted for annual cost-of-living increases, and they stop at 85. It doesn't apply the earnings test, which withholds benefits if you claim before full retirement age and keep working above $24,480 in 2026, or the family maximum when children also collect on the same record. SSA rounds benefits down to the dime; the calculator shows cents. Confirm the final numbers with SSA before you file.

Frequently asked questions
When can I start Social Security survivor benefits?
At 60, or at 50 if you're disabled and the disability started within seven years of your spouse's death. Starting before your survivor full retirement age cuts the benefit by up to 28.5%, so at 60 you get 71.5% of the full amount. Your own retirement benefit is separate and can't start before 62.
What is my survivor full retirement age?
It's on a different schedule from the retirement one. Born 1945 through 1956: 66. Born 1957: 66 and 2 months. 1958: 66 and 4 months. 1959: 66 and 6 months. 1960: 66 and 8 months. 1961: 66 and 10 months. 1962 or later: 67. Someone born in 1960 reaches full retirement age for their own benefit at 67 but for survivor benefits at 66 and 8 months.
What if my spouse claimed early?
The widow(er)'s limit caps your benefit at the larger of what your spouse was receiving or 82.5% of their PIA. A spouse with a $3,000 PIA who collected $2,100 from 62 leaves a survivor benefit of $2,475 at your survivor full retirement age. If you claim survivor benefits early, the normal age cut applies first, and the cap only matters when it's lower.
What if my spouse delayed past full retirement age?
Their delayed retirement credits carry over to you. For anyone born in 1943 or later that's 2/3 of 1% for each month they waited past full retirement age, up to 70, including months in the year they died. If they hadn't filed yet, the calculator works out those credits from their birth year and age at death.
Can I take one benefit now and switch to the other later?
Yes. Survivor benefits and your own retirement benefit are separate. You can take a reduced survivor benefit now and switch to your own at 70 if it's larger, or take your own at 62 and switch to the unreduced survivor benefit at your survivor full retirement age. SSA pays you the higher of the two at any time, not both.
