Survivor Benefit Plan (SBP) Calculator

Frequently Asked Questions

What is SBP?

Survivor Benefit Plan is an annuity that pays up to 55% of the retiree's elected base amount to a designated beneficiary (usually a spouse) after the retiree's death. The premium is deducted from gross retired pay (currently 6.5% of the elected base for spouse coverage).

When is SBP “paid up”?

Premiums stop after the later of 360 paid premiums (30 years) and age 70. After paid-up status, the annuity continues at no further cost. Members who retire at 40 typically pay until age 70, while those who retire at 50 hit 30 years of premiums first.

How does the calculator estimate value?

It models premiums paid (PV) vs expected survivor annuity payments (PV), using life-expectancy and discount-rate inputs. Spouse age gap matters - younger spouses raise expected lifetime payouts and SBP value.

Is SBP a good deal?

For most retirees with a younger spouse and no other large death benefit, SBP outperforms commercial term life on a risk-adjusted basis because it is inflation-protected and pays for life. It's usually weaker if you have a large estate or your spouse has independent income. This tool is educational, not financial advice.

How This Calculator Works

The Survivor Benefit Plan (SBP) is a federally subsidized annuity that pays a surviving spouse (or other eligible beneficiary) 55% of the retiree's elected retired-pay base for life. The retiree pays a monthly premium of 6.5% of the elected base for 360 months (30 years) of retirement or until the retiree's death - whichever comes first - and after 360 months SBP becomes "paid up" with no further premiums but full survivor coverage continues. This calculator estimates lifetime premium outlay, lifetime survivor benefits, and net present value (NPV) of electing SBP given a discount rate, retiree life expectancy, spouse age, and spouse life expectancy. Estimates only and a meaningful simplification of an irrevocable, lifelong decision - consult a fee-only fiduciary advisor before making your SBP election at retirement.

Formula / Method

Monthly premium = 6.5% × elected_base, paid for min(360 months, months_until_retiree_death). Monthly survivor benefit = 55% × elected_base, paid from retiree death until spouse death. Net present value compares the PV of the survivor annuity stream (discounted from each future month back to today) against the PV of the premium stream (also discounted). The premium stream is virtually certain to be paid in full as long as the retiree lives, so its present value is roughly a level-payment annuity. The benefit stream is contingent on (a) the retiree dying first and (b) the spouse outliving the retiree by some number of years - both conditions are probabilistic, and a robust analysis uses life-table mortality rather than point estimates. SBP premiums are deducted from retired pay pre-tax (reducing taxable retired pay), and survivor benefits are taxable income to the spouse.

Worked Example

An E-7 retires at 42 with elected SBP base of $3,750/month, spouse current age 58, life expectancy 88, retiree life expectancy 82. Monthly premium = 6.5% × $3,750 = $243.75. Premiums paid for 30 years (capped at 360 months) = $87,750 nominal. Spouse expected to outlive retiree by 6 years; monthly benefit = 55% × $3,750 = $2,062.50, total nominal benefits = 6 × 12 × $2,062.50 = $148,500. At a 3% real discount rate, PV of premiums ≈ $57,400 and PV of survivor benefits ≈ $59,200, for a small positive NPV around $1,800. The result is highly sensitive to assumed life spans - if the spouse outlives the retiree by 12 years instead of 6, NPV becomes strongly positive; if the spouse predeceases the retiree, total benefits are zero (though premiums paid through that date are NOT refunded except in narrow circumstances).

Common Mistakes

Comparing SBP to commercial term-life insurance on a same-premium basis without adjusting for the lifetime, inflation-indexed nature of the SBP annuity - term life pays a lump sum and stops at term end; SBP pays for the survivor's lifetime with COLA.

Forgetting that SBP COLA matches military retired-pay COLA (CPI), so $2,000/month today grows roughly with inflation over decades.

Electing the minimum base ($300/month) without realizing the 6.5% rate then applies to that base - small premiums but very small benefits.

Believing SBP premiums are refunded if the spouse dies first - they generally are not; coverage is suspended and a smaller premium structure applies if a new spouse is later acquired.

Treating the decision as reversible - SBP election is largely irrevocable; a one-time withdrawal opportunity exists between months 25–36 with spouse consent and never thereafter.

Tips & FAQ

Q: When is SBP "paid up"? A: After 360 months of premium payments AND the retiree has reached age 70 - both conditions must be met. From that point forward no premiums are deducted but full coverage continues. Q: Does VA Dependency and Indemnity Compensation (DIC) interact with SBP? A: The 2023 elimination of the "SBP-DIC offset" now allows surviving spouses to receive both SBP and DIC in full. Q: Is SBP a better deal for younger or older retirees? A: Generally better for younger retirees with younger spouses (more years of premiums but also more years of expected coverage with a healthy spouse); always model your specific scenario. Q: What if I'm unmarried at retirement? A: You can elect "former spouse" or "child only" coverage; uncovered single retirees have a one-year window after a later marriage to elect coverage. Always consult a fee-only fiduciary financial advisor and DFAS retired-pay counselors before making this irrevocable election.
