Short Answer
A spousal benefit is worth up to 50% of the working spouse's full-retirement-age benefit, and a survivor benefit is worth up to 100% of the deceased worker's benefit. You get the full amount only if you claim at your own full retirement age; claiming earlier reduces it. On a worker's $2,000 benefit, a spouse who claims at 62 (full retirement age 67) receives about $650 - just 32.5% of the worker's amount - versus $1,000 at full retirement age. A survivor can claim as early as 60 and receives as little as 71.5% of the deceased's benefit then, rising to the full 100% at survivor full retirement age. Delaying past full retirement age never raises a spousal benefit, but the higher earner delaying does raise the survivor benefit.
Key Takeaways
- Spousal benefit: up to 50% of the worker's full-retirement-age amount; you get the full 50% only at your own full retirement age.
- Survivor benefit: up to 100% of the deceased's benefit, including any delayed-retirement credits the worker earned.
- Claiming early cuts both. A spousal benefit falls to 32.5% of the worker's amount at 62 (FRA 67); a survivor benefit falls to 71.5% at age 60.
- Spousal starts at 62, survivor at 60 (or 50 if the survivor is disabled).
- No delayed credits on spousal: waiting past your full retirement age never increases a spousal benefit.
- You do not get both your own benefit and a spousal benefit in full - Social Security pays your own benefit plus a top-up for any excess, which at full retirement age equals the higher of the two.
- The higher earner delaying to 70 permanently raises the survivor benefit the surviving spouse will receive.
How the Calculator Works
The tool applies the Social Security Administration's own reduction formulas to the worker's benefit you enter. For the full rules and strategy, see the Spousal & Survivor Benefits Guide.
Step 1: Set the Base Benefit SSA
For a spousal benefit, the base is 50% of the worker's primary insurance amount (their benefit at full retirement age). For a survivor benefit, the base is 100% of what the deceased worker was receiving or entitled to, including any delayed-retirement credits they earned. If the worker's PIA is unknown, estimate it from their earnings history with the Social Security PIA Calculator.
Step 2: Find Your Full Retirement Age SSA
Your full retirement age comes from your year of birth: 66 for 1943-1954, rising in two-month steps to 66 and 10 months for 1955-1959, and 67 for 1960 and later. For a survivor, the SSA adds two years to your birth year, so survivor full retirement age reaches 67 only for those born in 1962 or later.
Step 3: Reduce for Claiming Early SSA
A spousal benefit is reduced 25/36 of 1% per month for the first 36 months before your full retirement age and 5/12 of 1% for each additional month - a maximum 35% cut at 62 (FRA 67), leaving 32.5% of the worker's amount. A survivor benefit is reduced on a prorated basis from 100% at full retirement age down to 71.5% at age 60.
Step 4: Compare With Your Own Benefit Confirmed
If you enter your own benefit at full retirement age, the tool pays your own benefit, reduced for your claiming age, plus a spousal top-up equal to half the worker's benefit minus your own, reduced by the spousal factors (42 U.S.C. 402(k)(3)(A); 20 CFR 404.407 and 404.411). Social Security does not pay both in full. Survivor benefits are more flexible: you can take a survivor benefit and your own retirement benefit at different times and switch to whichever is larger.

Practitioner Insight (LMN Tax Inc.)
LMN Tax Inc. - Planning Notes
The single most misunderstood point we correct is that a married person does not stack their own benefit on top of a spousal benefit. Since deemed filing became the rule, when you file you are filing for everything you are eligible for, and Social Security pays your own benefit plus a spousal top-up only if half your spouse's benefit is larger. If your own benefit already exceeds half of your spouse's, the spousal benefit is worth exactly zero, and clients are often surprised.
Survivor benefits are where the real money and the real mistakes live. Because a survivor receives up to 100% of the deceased worker's benefit including delayed credits, the decision the higher earner makes about delaying echoes for the rest of the surviving spouse's life. We routinely advise the higher earner to delay to 70 not for their own break-even but to lock in the largest possible survivor benefit, since the widow or widower will likely collect it for years.
We also separate the survivor benefit from the survivor's own retirement benefit, because they are two different claims you can start at different times. A common high-value move for a widow with her own work record is to take the survivor benefit early and let her own retirement benefit grow with delayed credits to 70, then switch to her own if it ends up larger. This calculator estimates one benefit at a time, so we run it twice and compare.
Finally, we always flag the government pension offset for anyone with a pension from work not covered by Social Security, because it can wipe out a spousal or survivor benefit entirely. That offset is outside this tool, and it is the one thing that most often makes the estimate here too high for public-sector retirees.
When This Calculator Does Not Cover Your Situation
- The government pension offset (GPO). If you receive a pension from government work not covered by Social Security, your spousal or survivor benefit can be reduced by two-thirds of that pension, sometimes to zero. This tool does not model the GPO.
- The family maximum. When several people draw benefits on one worker's record (a spouse plus children), total payments are capped by the family maximum, and each benefit may be reduced. That cap is not applied here.
- The widow's limit (RIB-LIM). If the deceased worker had claimed a reduced benefit early, the survivor benefit is capped at the larger of the worker's actual benefit or 82.5% of their primary insurance amount. Enter the deceased's actual amount to approximate this.
- The retirement earnings test. Claiming a spousal or survivor benefit before full retirement age while working can temporarily withhold benefits above an annual earnings limit; the withheld amount is not modeled - estimate it with the Social Security Earnings Test Calculator.
- Benefits for a spouse caring for a child. A spouse of any age caring for the worker's child under 16 or disabled can receive a full, unreduced spousal benefit; the early-claiming reduction here does not apply in that case.
- Taxes and Medicare. Up to 85% of benefits can be taxable, and Medicare Part B premiums are usually deducted from the check; neither is modeled.
Frequently Asked Questions
How much is the Social Security spousal benefit?
A spousal benefit is worth up to 50% of the working spouse's primary insurance amount (their benefit at full retirement age). You receive the full 50% only if you start it at your own full retirement age. Claiming earlier reduces it: the benefit is cut 25/36 of 1% per month for the first 36 months before your full retirement age and 5/12 of 1% for each additional month, so at 62 with a full retirement age of 67 the spousal benefit falls to 32.5% of the worker's amount. Delayed-retirement credits do not apply to spousal benefits, so there is no reason to wait past your full retirement age to claim one.
How much is a Social Security survivor benefit?
A widow or widower can receive up to 100% of what the deceased worker was receiving or entitled to at death, including any delayed-retirement credits the worker earned. You get the full 100% if you claim at your survivor full retirement age. Claiming earlier reduces it: the survivor benefit is as low as 71.5% at age 60 (the earliest age, or 50 if you are disabled) and rises on a prorated basis to 100% at your survivor full retirement age. A survivor's full retirement age lags the ordinary retirement schedule by two birth years, reaching 67 for those born in 1962 or later.
Can I get both my own Social Security and a spousal benefit?
No, you do not receive both in full. When you are entitled to your own retirement benefit and a spousal benefit, Social Security pays your own benefit first and then adds a spousal top-up only if half the worker's benefit is larger than your own. At full retirement age that works out to the higher of the two, not the sum. If you claim early, each piece is reduced separately: your own benefit by the retirement reduction and the top-up by the larger spousal reduction. If your own benefit already exceeds 50% of your spouse's benefit, the spousal benefit adds nothing. Survivor benefits work differently: you can take a survivor benefit and your own retirement benefit at different times and switch to whichever is larger later.
What is the difference between spousal and survivor benefits?
A spousal benefit is paid while the worker is alive and is worth up to 50% of the worker's full-retirement-age amount; you can start it as early as 62. A survivor benefit is paid after the worker dies and is worth up to 100% of the deceased's benefit; you can start it as early as 60. Survivor benefits include the deceased worker's delayed-retirement credits, so delaying the higher earner's claim raises the survivor benefit. Spousal benefits do not include delayed credits and max out at the worker's full retirement age.
Does waiting past full retirement age increase a spousal benefit?
No. A spousal benefit tops out at 50% of the worker's primary insurance amount at your full retirement age, and delayed-retirement credits do not apply to it, so waiting past your full retirement age to claim a spousal benefit only forfeits checks with no increase. Delayed credits do matter for survivor benefits, though, in a different way: because a survivor benefit is up to 100% of the deceased worker's benefit including any credits the worker earned by delaying, the higher earner delaying to 70 permanently raises the survivor benefit for the spouse who lives longer.
Can a divorced spouse collect Social Security on an ex's record?
Yes. If your marriage lasted at least 10 years, you are currently unmarried, and you are at least 62, you can claim a spousal benefit of up to 50% of your ex-spouse's benefit without affecting their benefit or their current spouse's benefit. If your ex-spouse has died, you may qualify for a divorced-survivor benefit of up to 100% of their benefit, and you can generally remarry after age 60 without losing it. The same early-claiming reductions apply as for a married spouse or a widow or widower.
Is the survivor benefit reduced if the worker claimed early?
It can be. If the deceased worker had already claimed a reduced benefit before their own full retirement age, a special rule (the widow's limit, or RIB-LIM) caps the survivor benefit at the larger of what the worker was actually receiving or 82.5% of the worker's primary insurance amount. If the worker had not yet claimed, or had delayed and earned credits, the survivor benefit is based on the higher amount. Enter the deceased's actual benefit amount to reflect this; the calculator applies only the survivor's own early-claiming reduction on top of the amount you enter.
What to Do Next
If You Are a Widow or Widower
Compare taking the survivor benefit now against letting your own benefit grow. Run the tool once for each benefit, then check how much is taxable with the Social Security Tax Calculator.
If You Also Have a Pension or IRA
Other retirement income raises the tax on your benefits and can trigger the government pension offset. Model the ripple with the Pension & Annuity Tax Calculator and plan withdrawals with the RMD Calculator.
Before You File
Confirm your benefit estimates and full retirement age by creating a my Social Security account at ssa.gov/myaccount, and read Is Social Security Taxable so a larger benefit does not surprise you at tax time.
Correction · October 2026. An earlier version of this calculator showed the higher of your own benefit and the spousal benefit. With both, you receive your own reduced benefit plus a separately reduced spousal top-up (20 CFR 404.407 and 404.411), so early-claim results changed; the input now asks for your own benefit at full retirement age. See our Corrections Policy and Log.
