SBP

Published May 7, 2026

Definition

SBP is a US military annuity benefit that provides ongoing income to a service member's surviving spouse or dependent children after the retiree's death. The retiree elects coverage at retirement at a cost of 6.5% of the elected base amount (up to full retired pay) and the survivor receives 55% of the elected base amount.

SBP is one of the most consequential decisions a service member makes at retirement. The election is irrevocable in most cases — once elected, the cost continues for life; once declined, it cannot be added later. Married service members must elect SBP at full coverage unless the spouse waives the coverage in writing.

The 6.5% cost is paid from retired pay; the 55% survivor benefit is taxable as income to the survivor. For service members whose spouse will outlive them by many years (typically the wife in male-retiree households given longevity differences), SBP can be a meaningful component of the surviving-spouse's retirement income. The benefit is inflation-adjusted via COLA, providing protection against inflation over the survivor's lifetime.

The alternative to SBP is private life insurance — a term-life policy covering the projected value of the lost retirement income. Whether SBP or private insurance is the better choice depends on the service member's age at retirement, the spouse's projected longevity, the comparative cost of insurance at the relevant age, and the intended use of any death benefit (income replacement vs. lump sum). Most planners consulted on the question recommend SBP for the income-replacement use case because of its inflation protection and the absence of insurability concerns.

Retirement
SBP elected
Service member elects full or reduced coverage. Spouse must consent to anything less than full. Premium begins from first retired-pay check.
Months 25–36
One-time withdrawal window
Service member (with spouse concurrence) may terminate coverage. No premium refund. Outside this window the election is locked.
Year 30 (month 360) + age 70
Paid-up status
Premiums stop; coverage continues at full benefit level.
Retiree's death
Survivor benefit begins
Spouse receives 55% of elected base, COLA-adjusted, for life or until remarriage before age 55.

Why this matters for synthetic data

Military-retiree households in synthetic test corpora need an SBP election state (covered / not covered, with base amount), the SBP premium deducted from retired pay (6.5% of base), and the projected 55%-of-base survivor benefit on the spouse record. The election decision is a planning surface: engines comparing SBP to private term life need both options modeled, including the term policy's age-banded premiums and the SBP COLA path. Joint-mortality projections distinguish SBP (lifetime survivor benefit) from term life (lump sum at the insured's death, finite). Disability-rated retirees with CRSC interact with SBP — the SBP base can shift if retired pay is reclassified.

Common pitfalls

Modeling SBP cost as a one-time decision without ongoing premium. The 6.5% is paid from every monthly retired-pay check for life (with paid-up status at 360 months and age 70+).
Treating the survivor benefit as tax-free. SBP payments to the survivor are taxable as ordinary income; only CRSC-style combat-related compensation is tax-free.
Comparing SBP to a single private-term-life premium quote. Honest comparison requires age-banded term policies over the survivor's projected lifetime, plus the insurability question (term renewal at older ages is often impractical).
Ignoring spouse-loss-of-eligibility scenarios. If the covered spouse dies first, SBP premiums continue to be paid until the retiree dies (with no future beneficiary) unless an SBP child-only or no-coverage status is elected. The premium is not refundable.

Examples

SBP base-amount sensitivity

Officer retires at O-5, 24 years of service. Retired pay $7,200/month. Full SBP coverage: base $7,200, premium $468/month (6.5%), survivor benefit $3,960/month (55%). Reduced-base election: base $3,000, premium $195/month, survivor benefit $1,650/month. Trade-off: lower premium today, lower lifetime survivor benefit. Engines comparing to private term life should solve for breakeven term-premium vs. SBP premium at each base amount, given the spouse's projected longevity.

Frequently asked questions

Can SBP be canceled later?+

Very limited windows. The major opportunity is the one-time withdrawal between months 25 and 36 of paying premiums (with spouse concurrence), which terminates coverage and refunds no premiums. Outside that window, SBP cannot be canceled — engines should model the irrevocability.

What's the paid-up provision?+

After 360 months of premium payments AND reaching age 70, SBP coverage continues with no further premiums. Modeled as a state transition at month 360 / age 70 (whichever is later). For service members retiring in their 40s, paid-up status arrives well before death; for late-career retirees, the provision may never trigger.

Does SBP coordinate with VA Dependency and Indemnity Compensation (DIC)?+

Yes. Historically SBP and DIC were offset (the 'widow's tax'), but legislation phased out the offset by 2023. Surviving spouses now receive both in full when both qualify. Engines should model the offset for projections of pre-2023 deaths and current rules for post-2023 cases.
