VA Disability Ratings Explained: How the VA Calculates Combined Ratings

What Is a VA Disability Rating?

A VA disability rating is a percentage assigned by the Department of Veterans Affairs that represents the severity of a service-connected disability. Ratings range from 0% to 100% in increments of 10%. The rating determines the monthly compensation amount the veteran receives. Higher ratings correspond to higher monthly payments, with 100% disability providing the maximum compensation plus additional benefits.

Disability ratings are based on the impact of the condition on your ability to work and perform daily activities. The VA uses specific criteria for each condition outlined in the Schedule for Rating Disabilities. A 10% rating might represent a mild condition with minimal impact, while a 100% rating represents total disability that prevents any substantial gainful employment.

How the VA Calculates Combined Ratings

The VA does not simply add disability ratings together. If you have a 30% rating and a 20% rating, your combined rating is not 50%. Instead, the VA uses a combined ratings table that starts with the highest rating and progressively adds lower ratings. The formula accounts for the fact that a veteran cannot be more than 100% disabled.

The calculation works by starting with the highest rating and subtracting it from 100 to find the remaining "able-bodied" percentage. The next rating is applied to that remaining percentage, not to the whole. This process continues for each additional rating. The result is then rounded to the nearest 10% to determine the combined rating.

Combined Rating Calculation Example

Consider a veteran with three disabilities: 30%, 20%, and 10%. Start with the highest rating (30%). The remaining able-bodied percentage is 70%. Apply the 20% rating to that 70%, which is 14%. Subtract 14 from 70, leaving 56%. Apply the 10% rating to that 56%, which is 5.6%. Subtract 5.6 from 56, leaving 50.4%. The combined disability is 100 minus 50.4, or 49.6%. Rounded to the nearest 10%, the combined rating is 50%.

If the ratings were simply added (30% + 20% + 10% = 60%), the veteran would receive higher compensation. The VA's method produces a lower combined rating, which is why understanding the calculation is important for veterans with multiple disabilities.

VA Disability Compensation Rates

Monthly compensation amounts depend on the disability rating and whether the veteran has dependents. The VA updates compensation rates annually based on cost-of-living adjustments. As of 2026, a veteran with no dependents receives approximately $171 per month for a 10% rating, $338 for 20%, $524 for 30%, $756 for 40%, $1,075 for 50%, $1,361 for 60%, $1,716 for 70%, $1,998 for 80%, $2,241 for 90%, and $3,737 for 100%.

Additional compensation is available for dependents. A veteran with a spouse receives approximately $114 more per month at 100% disability. Additional amounts are added for each child and for dependent parents. Veterans with 100% disability may also qualify for additional benefits such as Dependents' Educational Assistance, vocational rehabilitation, and health care priority.

Note: These figures are approximate and subject to annual cost-of-living adjustments. Always check the VA website for current compensation rates. The spouse additional amount at 100% differs from lower ratings due to different calculation methods.

Special Compensation Rules

The VA has special rules for certain combinations of disabilities. Bilateral disabilities — disabilities affecting both arms, both legs, or paired skeletal muscles — receive an additional 10% rating. This bilateral factor is added to the combined rating before applying the combined ratings table.

Veterans with certain severe disabilities may qualify for Special Monthly Compensation (SMC) in addition to regular disability compensation. SMC is available for conditions such as loss of use of a limb, blindness, being housebound, or requiring regular aid and attendance. SMC amounts are higher than standard compensation and recognize the additional care needs of severely disabled veterans.

Veterans rated 100% disabled may be eligible for Individual Unemployability (IU) if they are unable to maintain substantially gainful employment due to service-connected disabilities. IU allows veterans to receive 100% compensation even if their combined rating is less than 100%, provided they meet specific criteria regarding employment and disability.

How to Increase Your VA Disability Rating

If you believe your current rating does not accurately reflect the severity of your condition, you can file a claim for an increased rating. This requires evidence that your condition has worsened since the last rating or that the original rating was based on incomplete information. Medical evidence is critical — current medical records, doctor's statements, and examination results that document the severity and impact of your condition.

You can also file for new disabilities if you have conditions that were not previously rated or were denied. The key is establishing a service connection — proving that the condition was caused or aggravated by your military service. Service records, medical records from service, and nexus statements from medical professionals help establish this connection.

The appeals process allows you to challenge a rating decision you believe is incorrect. You have one year from the date of the decision to file a notice of disagreement. The appeals process can be lengthy and complex, and many veterans benefit from assistance from Veterans Service Organizations (VSOs) such as the Disabled American Veterans (DAV) or Veterans of Foreign Wars (VFW).

TDU and Temporary Ratings

Temporary Disability Ratings (TDU) are assigned for conditions that are expected to improve with treatment or time. These are typically assigned for convalescence from surgery, hospitalization, or certain temporary conditions. TDU ratings are usually assigned at 100% for a specified period, after which the condition is reevaluated and a permanent rating is assigned.

TDU ratings provide full compensation during the recovery period but do not become permanent. Once the temporary period ends, the VA will evaluate the residual impairment and assign a permanent rating based on the lasting effects of the condition. Veterans should understand that TDU is temporary and plan accordingly for the potential reduction in compensation when the temporary rating expires.

Common Mistakes to Avoid

One mistake is assuming that the VA will automatically increase your rating as your condition worsens. The VA does not proactively reevaluate ratings unless you file a claim for increase. If your condition has worsened, you must file a claim and provide evidence documenting the change. The burden of proof is on you to demonstrate that your condition has deteriorated.

Another error is submitting incomplete evidence when filing claims. The VA adjudicates claims based on the evidence in the file. If you do not submit comprehensive medical evidence, the VA may deny the claim or assign a lower rating than warranted. Gather all relevant medical records, doctor's statements, and supporting documentation before filing. Consider obtaining a medical nexus opinion if the connection between your condition and service is unclear.

Finally, do not miss deadlines. You have one year from the date of a rating decision to file a notice of disagreement if you disagree. You have one year from the date of discharge to file a claim for service connection for disabilities that appeared after discharge. Missing these deadlines can permanently forfeit your right to appeal or claim certain benefits.

Frequently Asked Questions

How does the VA combine multiple disability ratings?

The VA uses a combined ratings table rather than simple addition. The highest rating is applied first, then each subsequent rating is applied to the remaining "able-bodied" percentage. This method prevents the combined rating from exceeding 100% and accounts for the fact that multiple disabilities do not necessarily add up to total disability. The result is rounded to the nearest 10% to determine the final combined rating.

What is the minimum VA disability rating for compensation?

The minimum rating that provides monthly compensation is 10%. A 0% rating acknowledges a service-connected disability but provides no monthly compensation. However, a 0% rating can still be valuable because it establishes service connection, making it easier to file for an increased rating if the condition worsens in the future. Some veterans with 0% ratings may also qualify for other benefits such as VA health care.

Can I work with a 100% VA disability rating?

Yes, you can work with a 100% schedular disability rating if you are able. The 100% rating is based on the severity of your disabilities, not on your employment status. However, if you receive 100% compensation through Individual Unemployability (IU), you cannot work in substantially gainful employment. IU requires that you be unable to work due to your disabilities. Working while on IU can lead to termination of IU benefits.

How often does the VA reevaluate disability ratings?

The VA may reevaluate disabilities, but not automatically on a set schedule. Reevaluations are most common for temporary conditions or when the VA expects improvement. For permanent disabilities, the VA typically does not schedule routine reevaluations. However, the VA can reevaluate at any time if there is reason to believe your condition has improved. You can also request a reevaluation if your condition has worsened.

What is the difference between schedular and IU 100% ratings?

A schedular 100% rating is based on the actual severity of your disabilities as measured against the VA rating criteria. An IU 100% rating is based on unemployability — you receive 100% compensation because your disabilities prevent you from working, even if your combined rating is less than 100%. Both provide the same monthly compensation, but IU has additional restrictions regarding employment and may be reviewed if the VA believes your ability to work has improved.

Conclusion

The VA's combined ratings table consistently produces lower numbers than simple addition. Understanding that math is the first step to understanding your actual compensation level and identifying whether you have grounds to file for increases. If your ratings do not reflect the actual severity of your service-connected conditions, file for increases backed by medical evidence and nexus letters. The system is navigable once you understand the rules.
