VA Disability Calculator

What This Calculator Does

This tool estimates your combined VA disability rating and monthly compensation based on the service-connected conditions you enter. The VA uses a unique method to combine multiple disability ratings that does not simply add them together. This calculator applies that same method to give you a realistic estimate of your overall rating and the corresponding monthly payment amount.

How the VA Combined Rating System Works

The VA does not add disability percentages. Instead, it uses a formula based on the concept of whole-person efficiency. Each new condition is applied to the remaining non-disabled percentage of the veteran. This means the first condition has the largest impact, and each subsequent condition has a smaller effect on the combined total.

For example, a 50% rating leaves you 50% efficient. Adding a 30% condition means 30% of that remaining 50% is disabled, adding 15% to the total. The combined rating would be 65%, which rounds to 70%.

The calculator handles this rounding logic automatically, including the bilateral factor for conditions affecting paired limbs.

How to Use the Calculator

1. Enter each condition. Add every service-connected disability you have been rated for or are claiming.
2. Assign a rating percentage. Use the rating you received from the VA or your best estimate based on the VA's rating schedule.
3. Indicate bilateral conditions. If a condition affects both arms, both legs, or paired skeletal muscles, mark it as bilateral. The VA applies an additional factor for these.
4. Review your combined rating. The calculator shows your estimated combined percentage and the corresponding monthly compensation.

Understanding Your Results

The combined rating is displayed as a percentage rounded to the nearest 10. The VA rounds 5 to 4 down and 5 to 4 up. For example, a combined rating of 74% rounds to 70%, while 75% rounds to 80%.

The monthly compensation amount shown is based on the current VA compensation rate table for a veteran with no dependents. If you have a spouse, children, or dependent parents, your actual payment will be higher. The calculator provides a baseline estimate.

If you have a bilateral condition, the calculator applies the bilateral factor, which adds 10% of the bilateral combination value before combining with other conditions. This can increase your final rating by one or two rating steps.

Common Mistakes to Avoid

• Adding percentages directly. A 50% and a 50% rating do not equal 100%. The VA method gives a combined rating of 75%, which rounds to 80%.
• Forgetting bilateral conditions. Failing to mark bilateral conditions can underestimate your rating by 10% or more.
• Using temporary ratings. Some conditions have temporary ratings (e.g., post-surgery). This calculator uses standard ratings.
• Confusing individual ratings with combined rating. Your combined rating is not the sum of your individual ratings. It is a weighted combination.

Limitations

This calculator provides an estimate only. The actual VA rating determination involves medical examinations, evidence review, and official adjudication. The calculator does not account for:

• Special monthly compensation (SMC) for loss of use or specific severe conditions
• Dependent allowances
• Individual unemployability (TDIU) considerations
• State-specific benefits or additional compensation
• Pending claims or appeals that may change ratings

Always consult with a Veterans Service Officer (VSO) or accredited attorney for personalized advice regarding your specific claim.

Practical Use Cases

• Pre-claim planning. Estimate what your combined rating might be before filing a new claim.
• Appeal strategy. Understand how increasing one rating affects your total compensation.
• Secondary conditions. See how adding a secondary condition changes your overall rating.
• Budgeting. Get a realistic monthly compensation estimate for financial planning.
