SBP Calculator — Survivor Benefit Plan
The Survivor Benefit Plan (SBP) turns part of your military retired pay into a lifetime annuity for your spouse if you pass away first. You pay 6.5% of your elected base amount each month while retired; your survivor receives 55% of that base amount for life. Use this calculator to see your exact monthly cost, the payout your spouse would receive, and whether the math works for your family.

Calculation breakdown
Note: Premiums are deducted from gross retired pay before federal tax, so the true out-of-pocket cost is lower than the gross premium. SBP becomes paid-up after 30 years of premiums and age 70. At very low base amounts a slightly cheaper alternate formula (2.5% of a threshold + 10% of the rest) may apply — for nearly all retirees the 6.5% figure governs. Official SBP details.
