How VA Math Works
The VA combines disabilities starting with the highest percentage. Each additional disability is applied to the remaining efficiency. Combined values are rounded to whole numbers at each table step, with the final combined value rounded to the nearest 10%.
Example: A 50% disability combined with a 30% disability equals 65%, which rounds to a final 70% combined rating.
Important limitation: This calculator uses standard combined-rating calculations under 38 CFR § 4.25. It does not apply the bilateral factor under 38 CFR § 4.26, which can affect ratings involving qualifying disabilities of paired extremities. Special rating rules, exclusions, and VA determinations may also affect the official result.
