Combined Disability Rating Calculator
Calculate your VA combined disability rating accurately using the official VA math formula. Add your individual disability ratings below to see your combined total.
Your Combined Disability Rating
This is your combined disability rating based on the VA’s combined rating table. The VA uses this method to account for the overlapping impact of multiple disabilities.
Understanding the VA Combined Disability Rating Calculator
The VA combined disability rating calculator is an essential tool for veterans seeking to understand how the Department of Veterans Affairs (VA) calculates their overall disability rating when they have multiple service-connected disabilities. Unlike simple addition, the VA uses a specific formula that accounts for the overlapping nature of disabilities.
How the VA Combined Rating System Works
The VA doesn’t simply add your disability ratings together because that would potentially overstate your level of disability. Instead, they use a method that:
- Starts with your most severe disability rating
- Calculates how much “healthy” capacity remains
- Applies the next disability rating to the remaining healthy capacity
- Repeats this process for all disabilities
This method is based on the principle that you can’t be more than 100% disabled, and disabilities often overlap in their effects on your overall health and functioning.
The VA Combined Rating Table
The VA uses a specific combined rating table (found in 38 CFR ยง 4.25) to calculate combined ratings. Here’s how it works with some examples:
| Disability 1 | Disability 2 | Combined Rating |
|---|---|---|
| 20% | 20% | 36% |
| 30% | 20% | 44% |
| 50% | 30% | 65% |
| 60% | 40% | 76% |
Notice that in each case, the combined rating is less than the simple sum of the two ratings. This is because the VA’s method accounts for the fact that disabilities often affect the same areas of functioning.
Why the VA Uses This Calculation Method
The VA’s combined rating system is based on several important principles:
- Non-duplication: Prevents “double-counting” of disability effects that overlap
- Whole person concept: Considers how disabilities affect your overall ability to function
- Legal precedent: Established through court cases and VA regulations
- Medical accuracy: Better reflects the actual impact of multiple disabilities
For example, if you have a 50% disability for PTSD and a 30% disability for a back injury, the VA doesn’t simply add them to get 80%. Instead, they calculate:
- Start with 50% disability (50% of your capacity is affected)
- You have 50% healthy capacity remaining
- Apply 30% of the remaining 50% (which is 15%)
- Total disability is 50% + 15% = 65%
Common Misconceptions About VA Disability Ratings
Many veterans have misunderstandings about how VA disability ratings work. Here are some of the most common myths:
| Myth | Reality |
|---|---|
| The VA simply adds all my disability percentages together | The VA uses a combined rating table that accounts for overlapping disabilities |
| If I have three 10% disabilities, I should be 30% disabled | Three 10% disabilities actually combine to 27.1% (rounded to 27%) |
| I can’t work with a 100% disability rating | Many veterans with 100% ratings continue to work, especially if their disabilities don’t prevent employment |
| The VA will automatically combine all my disabilities | You must file claims for each condition you want service-connected |
How to Use This Calculator Effectively
To get the most accurate results from this combined disability rating calculator:
- Enter all your service-connected disability ratings
- Include both physical and mental health conditions
- Use your exact VA-assigned percentages (don’t round)
- Remember that 0% ratings don’t affect your combined rating
- Consider secondary conditions that may be service-connected
For example, if you have:
- 30% for PTSD
- 20% for tinnitus
- 10% for knee pain
The calculator will show your combined rating as 50% (not 60% as simple addition would suggest).
Understanding Bilateral Factor
One important aspect of VA disability calculations is the bilateral factor. If you have disabilities that affect both arms, both legs, or paired skeletal muscles, the VA may apply an additional calculation.
The bilateral factor adds:
- 10% of the combined rating for disabilities affecting both upper extremities
- 10% of the combined rating for disabilities affecting both lower extremities
- 5% of the combined rating for disabilities affecting paired skeletal muscles
For example, if you have:
- 20% disability for right knee
- 20% disability for left knee
The combined rating would be 36%, and then the VA would add 10% of 36% (3.6%, rounded to 4%) for a final rating of 40%.
Secondary Service Connection and Your Rating
Many veterans don’t realize they can receive additional disability ratings for secondary conditions – medical issues that result from or are aggravated by your service-connected disabilities.
Common examples include:
- Depression or anxiety secondary to chronic pain
- Sleep apnea secondary to PTSD
- Gastrointestinal issues secondary to medication side effects
- Radiating pain secondary to a back injury
To establish secondary service connection, you need:
- A current diagnosis of the secondary condition
- Medical evidence linking it to your service-connected disability
- A nexus opinion from a medical professional
Adding secondary conditions can significantly increase your combined disability rating and potentially qualify you for additional benefits.
VA Disability Rating Breakpoints
The VA has specific breakpoints where your compensation increases significantly. Understanding these can help you determine whether it’s worth pursuing an increase in your rating:
| Rating Percentage | 2023 Monthly Compensation (Veteran Alone) | Additional Amount with Dependent |
|---|---|---|
| 10% | $165.92 | +$0 |
| 20% | $327.99 | +$32.00 |
| 30% | $508.05 | +$50.00 |
| 40% | $731.86 | +$73.00 |
| 50% | $1,041.82 | +$104.00 |
| 60% | $1,319.65 | +$131.00 |
| 70% | $1,663.06 | +$166.00 |
| 80% | $1,933.15 | +$193.00 |
| 90% | $2,172.39 | +$217.00 |
| 100% | $3,621.95 | +$362.00 |
Note that these amounts increase with additional dependents (spouse, children, dependent parents). The VA’s official compensation rates provide complete tables for all family situations.
How to Increase Your VA Disability Rating
If your combined rating is lower than you believe it should be, consider these strategies:
- File for an increase: If your conditions have worsened, submit new medical evidence
- Add secondary conditions: Identify and claim conditions caused by your service-connected disabilities
- Apply for TDIU: If you can’t maintain substantially gainful employment due to your disabilities
- Get a DBQ: Have your doctor complete a Disability Benefits Questionnaire for each condition
- File for new conditions: You can add new claims at any time with supporting evidence
- Request a C&P exam: Ask the VA for a Compensation & Pension examination if you disagree with your rating
Remember that increasing your rating often requires new and material evidence – simply stating that your condition has worsened isn’t enough. You’ll need medical records, doctor’s statements, or other documentation to support your claim.
Understanding TDIU (Total Disability based on Individual Unemployability)
Even if your combined rating is less than 100%, you may qualify for TDIU if your service-connected disabilities prevent you from maintaining substantially gainful employment. To qualify:
- You must have at least one service-connected disability rated at 60% or higher, OR
- Two or more service-connected disabilities with at least one rated at 40% or higher and a combined rating of 70% or higher
- You must be unable to maintain substantially gainful employment due to your service-connected disabilities
TDIU pays at the 100% disability rate, even if your combined rating is lower. This can be a crucial benefit for veterans who can’t work due to their disabilities but don’t quite reach the 100% combined rating threshold.
Common Mistakes to Avoid
When dealing with VA disability ratings, veterans often make these costly mistakes:
- Not appealing low ratings: Many veterans accept their initial rating without realizing they can appeal
- Missing deadlines: You typically have one year from the decision date to appeal
- Incomplete evidence: Submitting claims without sufficient medical documentation
- Not claiming secondary conditions: Missing out on additional compensation
- Ignoring state benefits: Some states offer additional benefits based on VA ratings
- Not updating dependents: Forgetting to add new dependents who could increase your compensation
Working with a VA-accredited claims agent or attorney can help you avoid these mistakes and maximize your benefits.

Frequently Asked Questions About VA Disability Ratings
How often can I file for an increase in my VA disability rating?
You can file for an increase at any time, but you’ll need to show that your condition has worsened since your last rating decision. The VA typically looks for:
- New medical evidence showing progression of your condition
- New symptoms or limitations that weren’t previously documented
- Changes in your ability to work or perform daily activities
Can my VA disability rating be reduced?
Yes, but the VA must follow specific procedures. Your rating can only be reduced if:
- Your condition has materially improved on a sustained basis
- The VA provides you with a proposed reduction notice
- You have an opportunity to request a hearing and submit evidence
- The VA considers your entire medical history, not just recent improvements
Ratings for some conditions are protected after being in place for certain periods:
- 10 years: Rating can’t be reduced below the lowest level it has been at for the past 10 years
- 20 years: Rating is fully protected from reduction (with some exceptions)
- 5 years (for 100% ratings): Can’t be reduced without showing sustained improvement
How does the VA round disability ratings?
The VA follows specific rounding rules:
- Ratings are in 10% increments (0%, 10%, 20%, etc.)
- If your combined rating calculates to a number with a decimal, the VA rounds to the nearest 10%
- If the decimal is exactly .5, the VA rounds up (e.g., 34.5% rounds to 35%, which then rounds to 40%)
- Ratings below 10% are typically rounded down to 0% (though some conditions have minimum 10% ratings)
What’s the difference between “service-connected” and “non-service-connected” disabilities?
Service-connected disabilities are conditions that:
- Occurred or were aggravated during military service, OR
- Are secondary to a service-connected condition, OR
- Are presumed to be related to service (like certain conditions for Gulf War veterans)
Non-service-connected disabilities are conditions that:
- Existed before service and weren’t aggravated, OR
- Developed after service and aren’t linked to service-connected conditions
Only service-connected disabilities count toward your VA disability rating and compensation.
Can I work with a 100% VA disability rating?
Yes, you can work with a 100% VA disability rating in most cases. The key factors are:
- If you received 100% through scheduler rating (your conditions add up to 100%), you can work without limitation
- If you received 100% through TDIU, there are income limits (substantially gainful employment is typically considered $1,400/month or more as of 2023)
- If you’re working, the VA may review your TDIU status to ensure you still qualify
Many veterans with 100% ratings continue to work, especially if their disabilities don’t prevent employment or if they work in accommodated positions.
How do VA disability ratings affect other benefits?
Your VA disability rating can impact several other benefits:
- State benefits: Many states offer property tax exemptions, hunting/fishing license discounts, or other benefits based on VA disability ratings
- Education benefits: Some programs like Vocational Rehabilitation (VR&E) have eligibility based on disability ratings
- Health care: Higher ratings may qualify you for additional VA health care benefits
- Dependent benefits: Higher ratings can increase compensation for dependents
- Housing grants: Specially Adapted Housing (SAH) grants require certain disability ratings
- Life insurance: Veterans with service-connected disabilities may qualify for special life insurance programs
Always check with your local VA office or veteran service organization to understand all benefits available based on your specific rating.
Final Thoughts on VA Disability Ratings
Understanding how the VA calculates combined disability ratings is crucial for veterans seeking fair compensation for their service-connected conditions. While the math can seem complex, the principle is straightforward: the VA aims to compensate for your overall level of disability without double-counting overlapping effects.
Remember these key points:
- The VA never simply adds your disability percentages together
- Secondary conditions can significantly increase your combined rating
- Even if your combined rating is less than 100%, you might qualify for TDIU
- You can (and should) appeal ratings you believe are too low
- State and local benefits often provide additional support based on your VA rating
If you’re unsure about your rating or how to maximize your benefits, don’t hesitate to reach out to veteran service organizations or accredited representatives. They can provide guidance tailored to your specific situation and help you navigate the often-complex VA claims process.
Your service to our country deserves proper recognition and compensation. Understanding the VA disability rating system is the first step toward ensuring you receive all the benefits you’ve earned.
