How It Works

The VA uses "whole person" math to combine disability ratings — not simple addition. A 50% plus a 30% does not equal 80%. Instead, the 30% applies to the remaining 50% of your "healthy body," yielding 65% (rounded to 70%).

The Formula

Combined = 1 − ((1 − R1) × (1 − R2) × (1 − R3) × ...)
VA Rating = Round to nearest 10%

Variables

  • R1, R2, R3 — Individual disability ratings as decimals (largest applied first)
  • Remaining — After each rating, the remaining "healthy" percentage is reduced
  • Rounding — Final exact % is rounded to nearest 10% (0.5 rounds up)

Example

50% + 30% + 10%: Start at 100, apply 50% → 50 remaining. Apply 30% of 50 = 15 → 35 remaining. Apply 10% of 35 = 3.5 → 31.5 remaining. Combined = 68.5%, rounds to 70%.

Tips

  • The VA rounds 0.5% and above UP to the next 10% — 65% rounds to 70%, but 64% rounds to 60%.
  • Bilateral conditions (both knees, both shoulders) get a 10% boost before combining with other ratings.
  • At 100% (or TDIU), you qualify for Additional Special Monthly Compensation for dependents.
  • File claims for every service-connected condition — even 0% ratings establish service connection for future increases.
  • Veterans at 70%+ should explore Aid & Attendance and TDIU (Total Disability based on Individual Unemployability).
