How the Military Divorce Calculator Works

Military divorce involves federal laws that override state property rules. The Uniformed Services Former Spouses' Protection Act (USFSPA) authorizes state courts to treat military retirement pay as marital property divisible in divorce. The 10/10 rule determines whether DFAS (Defense Finance and Accounting Service) can pay a former spouse directly. This calculator covers the three most critical financial components: pension division, BAH treatment as income, and Survivor Benefit Plan (SBP) value.

All figures are estimates. Military divorce requires specialized legal counsel familiar with both federal military law and your state's family law statutes.

Key Formulas

Retirement Pay = Base Pay × (Years of Service × 2.5%) [BRS plan uses 2.0% multiplier] Coverage Fraction = Years Married While Serving ÷ Total Years of Service Spouse Share = Retirement Pay × Coverage Fraction × 50% 10/10 Rule: 10+ years married AND 10+ years of service AND 10+ years overlap → Qualifies for direct DFAS payment to former spouse BAH Total Compensation = Base Pay + BAH + BAS (all treated as income for support) SBP Benefit = Retirement Pay × 55% (full coverage) or 27.5% (partial) SBP Premium = Retirement Pay × 6.5%

The coverage fraction formula is the most commonly litigated calculation in military divorce. Courts apply the "time rule" — dividing the overlapping service-marriage years by total service years to determine what portion of the pension is marital property.

Example Calculation

Example: E-7 with 20 Years Service, 15 Years Married

Years of service20 years
Years married while serving14 years
Monthly base pay$5,800
Retirement pay (50%)$2,900/mo
Coverage fraction (14/20)70%
Marital portion of pension$2,030/mo
Spouse share (50%)$1,015/mo
10/10 rule met?Yes — direct DFAS payment

At $1,015/month, the former spouse receives $12,180 per year in pension income. Over 20 years of collection, this totals $243,600 in retirement benefits — a substantial marital asset often overlooked in divorce settlements.

Frequently Asked Questions

The 10/10 rule requires that the couple was married for at least 10 years, the service member served at least 10 years of creditable military service, and those two periods overlapped for at least 10 years. When all three conditions are met, DFAS can pay the former spouse's share of the pension directly, rather than having the service member distribute it. Importantly, not meeting the 10/10 rule does not eliminate the former spouse's right to a share of the pension — it only affects the payment method.
Yes. Basic Allowance for Housing (BAH) is not federally taxable, but most state family courts treat it as income for purposes of calculating child support and alimony. BAH rates vary significantly by location and rank — an O-5 in San Diego receives nearly $4,000/month in BAH, which dramatically affects support calculations. Basic Allowance for Subsistence (BAS) is also sometimes included. Always provide your complete Leave and Earnings Statement (LES) in divorce proceedings.
Eligibility for TRICARE after divorce depends on the "20/20/20" or "20/20/15" rule. The 20/20/20 rule: 20 years of marriage, 20 years of service, 20 years of overlap — grants full TRICARE coverage. The 20/20/15 rule: same requirements but only 15 years of overlap — grants one year of transitional TRICARE. Divorced spouses who do not qualify can purchase coverage through the Continued Health Care Benefit Program (CHCBP) for up to 36 months.
The Survivor Benefit Plan (SBP) is essentially life insurance on the military pension. If the service member dies first, SBP pays the designated beneficiary 55% of the covered retirement pay. In divorce, a court can order the service member to designate the former spouse as SBP beneficiary. The premium is 6.5% of covered pay, and coverage must be elected — or "deemed elected" — within one year of divorce. Without SBP, the former spouse's pension share simply stops when the service member dies.
Special pays like combat pay, hazardous duty pay, and bonuses are typically not included in pension division calculations since retirement pay is based on base pay only. However, they may be considered income for support purposes while actively received. The Servicemembers Civil Relief Act (SCRA) can also delay divorce proceedings while a service member is on active duty. Consult an attorney familiar with military divorce before proceeding.

When to Consult a Family Law Attorney

Military divorce involves federal law (USFSPA, SCRA), DFAS procedures, and benefit systems (TRICARE, SBP, BAH) that standard family lawyers may not know thoroughly. Consult an attorney who specializes in military divorce — ideally one familiar with DFAS court-order requirements and the distinction between pension division and direct pay eligibility under the 10/10 rule. Errors in military divorce orders can be very difficult to correct after finalization.
