Introduction
VA disability compensation is one of the most misunderstood benefits in the entire federal system -- and the misunderstanding costs veterans real money. The most common error: veterans add their individual disability percentages together and wonder why their combined rating is lower. A veteran with 50%, 30%, and 20% ratings does not receive 100% compensation. The VA uses the "whole person" method, where each subsequent rating is applied to the remaining able-bodied percentage, not the original 100%. That same veteran's combined rating is 74.8%, which rounds down to 70%. The VA's official rating regulations at 38 CFR Part 4 govern this calculation, and the formula is both counterintuitive and exact. This calculator applies the official VA whole person method -- including the bilateral factor -- to show your correct combined rating and 2026 monthly compensation.
What This Calculator Does
This VA disability rating calculator computes your combined VA disability rating using the official whole person method required by 38 CFR 4.25. Enter each service-connected disability percentage in order from highest to lowest. The calculator applies each rating to the remaining whole person capacity, adds the bilateral factor when applicable (10% of combined bilateral ratings for conditions affecting paired limbs or organs), rounds the final raw combined rating to the nearest 10%, and displays your 2026 monthly compensation for your rating level with and without dependents.
The Formula
The VA whole person method works by treating your body as 100% whole. After the first disability is applied, the remaining percentage represents your still-healthy capacity. Each subsequent disability is a percentage of that remaining capacity, not of the original 100%. Example: 50% disabled means 50% remains. A 30% second rating applied to that 50% adds 15% (30% of 50), giving 65% combined. A 20% third rating applied to 35% remaining adds 7%, giving 72%. The raw 72% rounds to 70%. The bilateral factor applies only to conditions affecting paired body parts (both knees, both shoulders, both eyes, bilateral hearing loss). For bilateral conditions, calculate their combined rating, multiply by 10%, and add that amount to the bilateral combined rating before processing with other disabilities.
Step-by-Step Example
List all ratings highest to lowest
Service-connected disabilities: Right knee (40%), PTSD (30%), Lumbar strain (20%), Tinnitus (10%). Sort highest to lowest: 40%, 30%, 20%, 10%.
Apply whole person method
Start: 100% whole. Apply 40%: 40% disabled, 60% remains. Apply 30% to 60% remaining: 30% x 60% = 18% added. Combined: 58%. 42% remains. Apply 20% to 42%: 20% x 42% = 8.4% added. Combined: 66.4%. 33.6% remains. Apply 10% to 33.6%: 10% x 33.6% = 3.36% added. Raw combined: 69.76%.
Check for bilateral factor
In this example, only one knee is affected (no bilateral factor). If both knees were rated (40% right, 20% left), combine them first: 40% + (20% x 60%) = 52%. Bilateral factor: 52% x 10% = 5.2% added. Bilateral combined: 57.2%, rounded to 57% for further processing with other disabilities.
Round and find 2026 compensation
Raw combined 69.76% rounds to 70% (rounds to nearest 10%; 5% and above rounds up, below 5% rounds down). 2026 monthly compensation at 70% for a veteran without dependents: $1,716/month. With spouse: $1,866/month. With spouse and one child: $1,987/month.
Real-World Use Cases
Initial Claim Multi-Condition Strategy
A veteran filing initial claims for five service-connected conditions uses the calculator to model different scenarios: which conditions, if rated at different percentages, will change the combined rating enough to reach the next 10% threshold and its compensation increase. The difference between 60% ($1,361/month) and 70% ($1,716/month) is $355/month -- $4,260/year. Knowing which condition's rating increase produces that jump guides where to invest in additional medical evidence.
Increase Claim Decision
A veteran currently rated at 70% combined (50% PTSD, 30% degenerative disc disease, 10% migraines) wonders if filing to increase migraines from 10% to 30% is worth the effort. The calculator shows: new combined with 30% migraines = 50% + (30% x 50%) = 65% + (30% x 35%) = 65% + 10.5% = 75.5%, rounding to 80%. Compensation jumps from $1,716 to $2,063/month -- $347/month more. Yes, the increase claim is worth filing with supporting medical documentation.
Total Disability (TDIU) Eligibility Check
A veteran with a combined rating of 60% is unable to work due to service-connected disabilities. Total Disability based on Individual Unemployability (TDIU) pays at the 100% rate ($3,737/month) when a veteran has one disability rated at 60%+ or combined rating of 70%+ with at least one disability rated 40%+. A 60% combined with one 40%+ condition qualifies. This calculator helps veterans identify whether their current ratings meet TDIU threshold requirements.

|---|---|---|---|---|
| 10% | $171 | $171 | $171 | $2,052 |
| 30% | $524 | $586 | $636 | $6,288 |

| 90% | $2,241 | $2,423 | $2,573 | $26,892 |
| 100% | $3,737 | $3,946 | $4,115 | $44,844 |
Common Mistakes to Avoid
Adding disability percentages directly instead of applying the whole person method. 50% + 30% + 20% does not equal 100%; it equals approximately 72% combined under VA math. This is the most common misunderstanding of VA disability ratings, and it leads veterans to believe they should be rated higher than they are.
Forgetting to apply the bilateral factor for conditions affecting paired limbs or organs. If you have service-connected conditions in both knees, both shoulders, both hips, both ankles, or bilateral hearing loss, the 10% bilateral factor applies to the combined rating of those bilateral conditions. Missing the bilateral factor can result in a final combined rating that is 5-10% lower than you are entitled to.
Rounding intermediate steps instead of only rounding the final combined rating. The whole person method applies percentages through all disabilities without rounding until the very end. Rounding after each step produces a higher false combined rating. The VA rounds only once: after the final raw combined rating is calculated.
Confusing combined rating with compensation rate. A 94.6% raw combined rating rounds to 90%, not 100%. The rounding rule is: 5% and above rounds up to the next 10%, below 5% rounds down. The compensation paid corresponds to the rounded rating, not the raw calculated percentage.
