Social Security Spousal & Survivor Benefit Calculator
↻ Updated 2026See the spousal top-up under deemed filing, the survivor benefit a higher earner's claiming age locks in, and divorced-spouse eligibility — the part of the claiming decision a single-earner estimate leaves out.
Educational calculators — always consult a licensed professional before making financial decisions.
Under the Bipartisan Budget Act of 2015, filing for your own retirement benefit while eligible for a spousal benefit deems you to have filed for both — SSA does not let you collect just the spousal amount while your own benefit keeps growing. You get your own reduced benefit plus an "excess" top-up so the combined total equals the higher of the two. Only people born before January 2, 1954 could still restrict their application to spousal-only — that cohort turned 72 in 2026, so this is now historical for new claims.
The survivor base is the higher earner's own benefit as they actually claimed it — unless they claimed before their FRA, in which case the widow(er)'s limit guarantees you at least 82.5% of their PIA regardless of how early they claimed. If they waited past FRA, delayed retirement credits pass straight through to you: on these numbers, $3,000 of PIA becomes a $2,475 survivor base if they claimed at 62, or $3,720 if they waited to 70 — a $1,245/month difference for whoever outlives them, for life.

How to read your spousal and survivor estimate
Three benefits share one page because they share one mechanic: a percentage of somebody else's Primary Insurance Amount, reduced for claiming early. On the defaults — a $3,000 PIA for the higher earner, $1,200 for the lower earner, both claiming at 67 — the lower earner gets a combined $1,500 while both are alive, and would get $3,000 if the higher earner dies after claiming at FRA. The gap between those two numbers is the whole reason survivor benefits change how a couple should think about delaying.
How spousal, survivor and divorced-spouse benefits are calculated
A spousal benefit is capped at 50% of the higher earner's PIA, reduced if the lower earner claims before their own Full Retirement Age. Since the Bipartisan Budget Act of 2015, claiming your own retirement benefit and claiming a spousal benefit are no longer separable — filing for one deems you to have filed for both, and SSA pays your own reduced benefit plus a top-up (the 'excess spousal amount') so the combined total matches whichever is larger.
A survivor benefit works differently. Instead of a fixed 50%, the surviving spouse inherits the deceased worker's own benefit as they were actually receiving it — including any delayed retirement credits if the worker waited past FRA. If the worker claimed early, a floor called the widow(er)'s limit guarantees the survivor at least 82.5% of the worker's PIA, so an early claim by the worker can't crater what their survivor eventually receives. The survivor's own claiming age then applies a second reduction, phased in from age 60.
A divorced-spouse or divorced-survivor benefit runs on the exact same formulas, gated by a 10-year marriage requirement instead of a current marriage.
Spousal benefit (both alive), claim age ≥ 62: excess = max(0, 50% × higher PIA − your own PIA) spousal reduction = 25/36% per month early, first 36 months + 5/12% per month early, beyond 36 months (no reduction at/after your FRA; no credit past FRA) combined benefit = your own reduced benefit + excess × spousal reduction Survivor benefit, claim age ≥ 60: survivor base = worker's benefit as claimed, floored at 82.5% × PIA if worker claimed before their FRA survivor reduction = phases from 71.5% at 60 to 100% at your FRA survivor benefit = survivor base × survivor reduction you receive the larger of the survivor benefit and your own benefit
- higher PIA
- The higher earner's Primary Insurance Amount — their benefit at their own Full Retirement Age — the base every spousal and survivor figure derives from
- excess
- The spousal top-up above your own benefit — zero once your own PIA reaches 50% of theirs
- widow(er)'s limit
- The 82.5%-of-PIA floor on a survivor benefit — protects survivors when the deceased claimed early; irrelevant if the deceased claimed at or after FRA
- survivor reduction
- The age-60-to-FRA phase-in on the survivor's own claiming age — distinct from, and gentler than, the retirement-benefit reduction curve
- deemed filing
- Post-2015 rule: filing for one benefit files for both — eliminated the old strategy of collecting spousal-only while your own benefit grew
The detail that trips people up most is that the higher earner's claiming age changes almost nothing while both spouses are alive — it only changes what a survivor eventually inherits. A couple weighing whether the higher earner should delay to 70 is really pricing an insurance policy for whichever of them lives longer, not maximizing income for both of them right now.
None of this replaces a full household plan — see the Social Security estimator for the base claiming-age math on a single worker's own benefit, which every figure here builds on.
Worked examples
Example: the deemed-filing top-up, both spouses alive
The calculator's defaults — a $3,000 PIA for the higher earner, $1,200 for the lower earner, both claiming at 67.
| 50% of higher earner's PIA | $1,500 |
| Minus lower earner's own PIA | − $1,200 |
| Excess spousal amount at FRA | $300 |
| Claiming at FRA — no reduction | × 100% |
| Lower earner's own benefit at 67 | $1,200 |
| Combined benefit paid$1,200 own + $300 excess | $1,500 |
$1,500 a month — exactly 50% of the higher earner's PIA, because that's larger than the lower earner's own $1,200. Claim at 62 instead and it drops to $1,035: the own-benefit portion falls to $840 (70% of $1,200) while the excess falls to $195 (65% of $300) — two different reduction curves stacked on top of each other, which is why the combined total isn't a simple 65% of $1,500.
Example: the higher earner's claiming age sets the survivor floor
Same $3,000 PIA for the higher earner. The survivor claims at their own FRA of 67, so no survivor-side reduction applies — isolating what the higher earner's own choice does.
| If higher earner claimed at 62$3,000 × 70% | $2,100 |
| Widow(er)'s limit floor (82.5% of PIA) | $2,475 |
| Survivor base (the larger of the two) | $2,475 |
| If higher earner claimed at 70 instead$3,000 × 124%, passes straight through | $3,720 |
| Survivor's gain from the higher earner delaying$3,720 − $2,475, for life | $1,245/mo |
The widow(er)'s limit means claiming at 62 doesn't cost the survivor the full 30% cut — it costs them a floor of 82.5% of PIA instead of 70%. But delaying to 70 still lands the survivor $1,245 a month higher, for as long as they live. That's the concrete version of the claim in this page's title: for a couple, the survivor mechanic can dominate the claiming decision more than either spouse's own breakeven math.
Frequently asked questions
How much is a spousal Social Security benefit?
Up to 50% of the higher earner's Primary Insurance Amount, if you claim at your own Full Retirement Age. Claim earlier — as early as 62 — and it's reduced: 25/36 of 1% for each of the first 36 months early, then 5/12 of 1% for each month beyond that, down to a floor of 32.5% of their PIA at 62 (SSA, Benefits For Your Spouse).
If your own PIA is already at least 50% of theirs, the spousal benefit adds nothing — you simply keep your own. If it's less, you get your own benefit plus the difference (the 'excess'), which is what deemed filing pays out automatically rather than as a choice.
What is deemed filing and how does it change spousal benefits?
Since the Bipartisan Budget Act of 2015, filing for your own retirement benefit while you're also eligible for a spousal benefit deems you to have filed for both at once, and SSA pays the higher combined amount rather than either one alone (SSA POMS GN 00204.035). This closed off the old 'file a restricted application for spousal only, let your own benefit keep earning delayed credits' strategy.
That strategy still exists for a narrow group: anyone born before January 2, 1954 could file a restricted application for spousal benefits only. By 2026 that entire cohort has turned at least 72, so the exception is now essentially historical rather than a live planning option.
Does the higher earner's claiming age affect the spousal benefit?
No — and this is the single most counterintuitive rule on this page. A spousal benefit is defined as a percentage of the worker's PIA, not of whatever the worker actually collects. Whether the higher earner claims at 62 or waits to 70, the spousal benefit calculation uses the same 50%-of-PIA figure.
It does affect the survivor benefit. A worker who delays passes their larger, delayed-credit-boosted benefit straight through to a surviving spouse; a worker who claims early leaves the survivor with a benefit floored at 82.5% of PIA rather than the full amount. That asymmetry — no effect on the spouse, a large effect on the survivor — is exactly why the claiming decision for the higher earner is really a survivor-insurance decision for a couple, not just an income decision for one person.
How much is a Social Security survivor benefit, and when can I claim it?
As early as age 60 (50 if you're disabled — not modeled here), at a reduced rate. Full survivor benefits — up to 100% of what the deceased worker was receiving — are available at your own survivor Full Retirement Age. Claiming at exactly 60 produces the maximum reduction, to 71.5% of the survivor base; the percentage rises in a straight line to 100% at FRA (SSA Publication No. 05-10084, Survivors Benefits).
What the deceased worker actually receives matters: if they claimed before their own FRA, the survivor's base is floored at 82.5% of their PIA no matter how early they claimed (the widow(er)'s limit) — but if they waited past FRA, any delayed retirement credits they'd earned pass straight through to the survivor's base instead.
What are the rules for divorced-spouse and divorced-survivor Social Security benefits?
The marriage must have lasted 10 years or more, and you must currently be unmarried, at least 62 (60 for a divorced-survivor benefit). If your ex hasn't filed for their own benefit yet, you can generally still claim as an 'independently entitled divorced spouse' once you've been divorced at least 2 years (SSA POMS RS 00202.005, Divorced Spouse).
The amounts follow the same formulas as a current spouse's — up to 50% of your ex's PIA while both are alive, and the same survivor mechanics if your ex has died. Crucially, none of it reduces what your ex or their current spouse receives; divorced-spouse benefits are paid entirely separately.
What is the full retirement age table for spousal and survivor benefits?
For retirement and spousal benefits: 66 for anyone born 1943–1954, rising two months per birth year to 66 and 10 months for 1959, then 67 for anyone born 1960 or later (SSA, Retirement Age and Benefit Reduction). Survivor benefits use a table offset by two birth years — the same 66-to-67 progression, but reaching 67 at birth year 1962 rather than 1960 — so someone born 1960 or 1961 can have a slightly lower survivor FRA than their own retirement FRA.
This calculator uses 67 throughout, which is exact for anyone born 1962 or later and a close approximation — a few months off — for anyone born 1955 through 1961.
What this spousal, survivor and divorced-spouse calculator doesn't handle
The three benefit formulas above are implemented in full. Several real-world complications sit outside them.
- Full Retirement Age simplified to 67 — Exact for retirement/spousal benefits born 1960+ and survivor benefits born 1962+. Anyone born 1955–1961 has a slightly different survivor FRA, a detail this page does not model.
- The earnings test — Claiming any of these benefits before your FRA while still working can trigger withholding above an annual earnings limit. Not modeled — withheld amounts are credited back later, but this page shows the unreduced-by-work figure.
- Taxation of benefits — Up to 85% of combined Social Security income (including spousal and survivor benefits) can be taxable depending on your combined income. This page shows gross benefits only.
- WEP and GPO — The Windfall Elimination Provision and Government Pension Offset can reduce or eliminate spousal and survivor benefits for people with a pension from work not covered by Social Security. Neither is applied here.
- Disabled-widow(er) benefits from age 50 — A surviving spouse who is disabled can claim as early as 50, at a different reduction schedule. Not modeled — this page's survivor floor is age 60.
- Whole years only — Real SSA reductions are computed in months. The sliders here move in whole years, so a claim at, say, 64 years and 7 months would land between two values this page shows.
- Not financial advice — An educational estimate built from public formulas. Confirm your own figures with SSA directly — a spousal, survivor, or divorced-spouse claim involves case-specific details this page cannot see.
