Understanding VA Disability Math
Calculating your VA disability rating is not as simple as adding up your percentages. The Department of Veterans Affairs uses a unique method often called "VA Math" based on the concept of "Whole Person efficiency."
The logic assumes a person starts as 100% efficient. If you have a 50% disability rating, you are considered 50% efficient. If you have a second disability rated at 30%, it is not added to the 50%. Instead, it is applied to the remaining efficiency.
How the Calculation Works (Example)
Let's say a veteran has three disability ratings: 50%, 30%, and 10%.
Step 1: Start with the highest rating: 50%. The remaining efficiency is 50% (100 – 50).
Step 2: Apply the second rating (30%) to the remaining efficiency. Calculation: 30% of 50 = 15%. Add this to the original 50%: 50% + 15% = 65% combined. Remaining efficiency is now 35%.
Step 3: Apply the third rating (10%) to the remaining efficiency (35). Calculation: 10% of 35 = 3.5%. Add to current total: 65% + 3.5% = 68.5%.
Step 4: Round to the nearest whole number. 68.5 rounds to 69%.
Step 5: The final rating is rounded to the nearest 10%. 69% rounds up to a 70% Final Rating.
2024 VA Disability Pay Rates
Once your combined rating is determined, your monthly compensation is based on that percentage and your dependent status. Note that the VA does not pay additional compensation for dependents if your combined rating is 0%, 10%, or 20%.
Key Factors Affecting Pay
Base Rate: The amount paid to a veteran with no dependents.
Dependents: Additional amounts are added for a spouse, children under 18, children 18-23 in school, and dependent parents.
Bilateral Factor: If you have disabilities affecting both arms or both legs, an additional 10% is added to the value of those specific disabilities before combining them with others.
Cost of Living Adjustment (COLA): Rates typically increase annually based on SSA COLA announcements.
Why is the "Bilateral Factor" Important?
The bilateral factor acknowledges that having disabilities on both sides of the body (e.g., left knee and right knee) creates a greater limitation than the sum of the individual disabilities. While this calculator uses standard combination logic, veterans with bilateral conditions should ensure the VA applies this factor during their official rating decision, as it can push a rating from, for example, 89% (rounded to 90%) to 95% (rounded to 100%).

// 30-100%: The added amount for children is flat per child usually?
