Step-by-Step VA Math Breakdown
VA "whole person" math: each condition takes a percentage of your remaining able body, not a flat sum. This is why 60% + 40% does not equal 100%.
0Start with 100% whole person100.00% remaining
1PTSD (70%): 100.0000 × 0.30 = 30.0000 remaining → 70.00% disabled so far 30.00% remaining
2Lumbar Spine (20%): 30.0000 × 0.80 = 24.0000 remaining → 76.00% disabled so far 24.00% remaining
3Tinnitus (10%): 24.0000 × 0.90 = 21.6000 remaining → 78.40% disabled so far 21.60% remaining
✓ Combined = 100% − 21.6000% = 78.40% → Rounded to nearest 10%: 80%80% Final
VA rounding rule: 1–4 rounds down, 5–9 rounds up to the next 10%. Your exact value of 78.40% rounds up to 80%.
