Combined Ratings Calculator

Calculate your combined disability rating accurately using the VA’s combined rating table. Add multiple service-connected disabilities to determine your total compensation percentage.

Comprehensive Guide to Understanding Combined Ratings Calculator

The VA combined ratings calculator is an essential tool for veterans seeking to understand their total disability compensation. The Department of Veterans Affairs (VA) uses a specific method to combine multiple disability ratings that isn’t simply additive. This guide will explain how the combined ratings system works, why it’s important, and how to use our calculator effectively.

How VA Combined Ratings Work

The VA doesn’t simply add up your disability percentages. Instead, they use a combined rating table that accounts for the “pyramiding” effect of multiple disabilities. Here’s how it works:

1. Start with your highest rating – This becomes your base percentage
2. Apply the next rating – This is where the math gets interesting. The VA calculates what percentage the next disability affects the remaining “healthy” portion of your body
3. Continue the process – Each additional disability is applied to the remaining percentage of your “healthy” body
4. Round to the nearest 10% – The VA rounds all final ratings to the nearest 10%

For example, if you have a 50% disability and a 30% disability:

• Start with 50% (50% disabled, 50% healthy)
• Apply 30% to the remaining 50% healthy portion: 30% of 50% = 15%
• Add to original 50%: 50% + 15% = 65%
• Round to nearest 10%: 70% final rating

Why the VA Uses This System

The VA’s combined rating system is based on the principle that you can’t be more than 100% disabled. If they simply added percentages, veterans with multiple disabilities could exceed 100%, which doesn’t make mathematical sense. The current system ensures that:

• No veteran exceeds 100% total disability
• The impact of each additional disability is properly weighted
• The system remains fair and consistent across all claims

Common Misconceptions About Combined Ratings

Many veterans have misunderstandings about how combined ratings work. Here are some common myths:

1. Myth: Ratings are simply added together – As we’ve seen, the VA uses a more complex calculation method.
2. Myth: A 100% rating means you’re completely disabled in all areas – A 100% rating means your disabilities combine to completely impact your ability to work, but you may still have some functional abilities.
3. Myth: You can’t work with a 100% rating – Some veterans with 100% ratings do work, though they may face significant challenges.
4. Myth: The VA will automatically combine all your disabilities – You often need to file for secondary conditions to have them properly rated and combined.

How to Use Our Combined Ratings Calculator

Our calculator makes it easy to determine your combined rating:

1. Enter your current rating – If you don’t have one, start with 0%
2. Add your individual disability ratings – Use the “Add Another Disability” button for multiple ratings
3. Click “Calculate Combined Rating” – Our tool will apply the VA’s combined rating table
4. Review your results – The calculator shows your combined rating and a visual breakdown

Remember that this calculator provides an estimate. Your actual VA rating may differ based on:

• The specific details of your disabilities
• How the VA rates the severity of each condition
• Whether some disabilities are considered “secondary” to others
• Any special rules that apply to your particular conditions

Understanding VA Disability Rating Tables

The VA uses specific tables to combine ratings. These tables are based on the principle of “remaining efficiency” – essentially, how much of your body’s function remains after accounting for each disability.

Current Rating	New Disability Rating	Combined Rating
0%	10%	10%
10%	10%	19%
20%	20%	36%
30%	30%	51%
40%	40%	64%
50%	50%	75%
60%	60%	84%
70%	70%	91%

As you can see from the table, the combined rating is always less than the simple sum of the individual ratings. This is why many veterans are surprised when they receive their combined rating from the VA.

Bilateral Factor Considerations

One important factor in VA ratings is the “bilateral factor.” If you have disabilities that affect both arms, both legs, or paired skeletal muscles, the VA may apply an additional consideration:

• When you have bilateral disabilities, the VA adds 10% to your combined rating before rounding
• This can sometimes push your rating to the next higher 10% increment
• Not all paired disabilities qualify – they must meet specific criteria

For example, if you have:

• 30% rating for right knee
• 20% rating for left knee
• 10% rating for tinnitus

The knees would qualify for bilateral consideration, potentially increasing your combined rating.

Secondary Conditions and Combined Ratings

Many veterans don’t realize that secondary conditions can significantly impact their combined rating. A secondary condition is one that:

• Is caused by a service-connected disability
• Is aggravated by a service-connected disability

Common examples include:

• Depression or anxiety secondary to chronic pain
• Sleep apnea secondary to PTSD
• Radiating pain secondary to a back injury
• Gastrointestinal issues secondary to medication for other service-connected conditions

When you file for secondary conditions, the VA will:

1. Evaluate the connection between your service-connected disability and the new condition
2. If approved, assign a rating to the secondary condition
3. Combine it with your existing ratings using the combined rating table

Primary Condition	Common Secondary Conditions	Potential Rating Impact
PTSD	Depression, Sleep Apnea, Migraines	10-50% additional rating
Back Injury	Radiating Pain, Sciatica, Depression	10-40% additional rating
Knee Injury	Hip Problems, Foot Problems	10-30% additional rating
Tinnitus	Hearing Loss, Depression, Anxiety	10-30% additional rating
Diabetes	Neuropathy, Retinopathy, Kidney Disease	20-60% additional rating

Strategies to Maximize Your Combined Rating

While you should never exaggerate symptoms, there are legitimate ways to ensure you receive the proper rating for your service-connected disabilities:

1. File for all service-connected conditions – Many veterans leave money on the table by not filing for all eligible conditions
2. Document secondary conditions – Work with your doctor to establish connections between your service-connected disabilities and other health issues
3. Get proper medical evidence – Detailed medical records, buddy statements, and private medical opinions can strengthen your claim
4. Understand the rating criteria – Study the VA’s rating schedule for each of your conditions to understand how they assign percentages
5. Consider a DBQ – Disability Benefits Questionnaires completed by your doctor can provide strong evidence
6. Appeal if necessary – If you believe your rating is too low, don’t hesitate to appeal with additional evidence

Remember that the VA’s combined rating system is complex, and small differences in individual ratings can lead to significantly different combined ratings. Our calculator helps you understand how these ratings interact.

Common Mistakes Veterans Make with Combined Ratings

Avoid these common pitfalls when dealing with VA disability ratings:

• Not filing for secondary conditions – This is one of the biggest missed opportunities for increasing your rating
• Accepting the first rating without review – Always carefully review your rating decision and consider an appeal if it seems incorrect
• Missing deadlines – The VA has strict deadlines for appeals and additional claims
• Not getting independent medical opinions – Sometimes VA examiners miss things that private doctors catch
• Assuming all conditions are permanent – Some ratings can increase over time if your condition worsens
• Not understanding bilateral factor – Many veterans miss out on this potential rating increase

Frequently Asked Questions About Combined Ratings

How often can I file for an increased rating?

You can file for an increased rating at any time if your condition has worsened. There’s no limit to how often you can file, but you’ll need medical evidence showing progression of your disability.

Can my combined rating decrease?

Yes, though it’s relatively rare. The VA can propose to reduce your rating if they determine your condition has improved. You’ll have the opportunity to appeal any proposed reduction.

What’s the difference between combined rating and total rating?

The combined rating is the VA’s mathematical combination of all your individual ratings. The total rating is simply the sum of all individual ratings before combination. The combined rating is what determines your compensation.

How does the VA round ratings?

The VA rounds to the nearest 10%. Ratings ending in 1-4 round down, and ratings ending in 5-9 round up. For example, 65% rounds to 70%, while 64% rounds to 60%.

Can I work with a 100% rating?

Yes, some veterans with 100% ratings do work. However, if you’re receiving Total Disability based on Individual Unemployability (TDIU), there are restrictions on substantial gainful employment.

What if I disagree with my combined rating?

If you believe your combined rating is incorrect, you can:

• File a Supplemental Claim with new evidence
• Request a Higher-Level Review
• File an appeal to the Board of Veterans’ Appeals

Our combined ratings calculator can help you understand whether your VA rating seems correct based on your individual disability percentages.

Final Thoughts on Combined Ratings

Understanding how the VA combines disability ratings is crucial for every veteran. The system can seem confusing at first, but it’s based on logical principles designed to fairly compensate veterans for their service-connected disabilities. Remember these key points:

• The VA doesn’t simply add your disability percentages together
• Each additional disability is applied to your remaining “healthy” percentage
• Secondary conditions can significantly impact your combined rating
• The bilateral factor can provide an additional boost for paired disabilities
• Our calculator provides estimates – your actual VA rating may vary
• Always review your rating decision carefully and appeal if necessary

By understanding how combined ratings work and using tools like our calculator, you can better navigate the VA disability system and ensure you receive the compensation you’ve earned through your service.
