VA Disability Ratings Explained: 0% to 100%

When the VA approves a disability claim, the next question is often just as important as approval itself: What rating did the VA assign?

A VA disability rating is the percentage the VA uses to measure how much a service-connected condition affects a veteran’s overall health and ability to function. That rating can affect monthly compensation, access to certain benefits, and whether a veteran may qualify for additional support. VA disability ratings usually range from 0% to 100%, increasing in 10% increments.

For veterans, understanding the rating system is critical. A claim may be approved, but the assigned rating may still be too low. A veteran may have multiple disabilities, but the combined rating may not equal simple addition. A condition may worsen over time, creating a need to request an increase. And in some cases, a rating may even be reduced if the VA believes the condition has improved.

Here is what veterans should know about how VA disability ratings work.

How VA Disability Ratings Are Assigned

The VA assigns disability ratings based on the severity of a service-connected condition. According to the VA, the rating represents how much a disability decreases a veteran’s overall health and ability to function. The VA uses the rating to determine monthly disability compensation and eligibility for certain additional benefits.

Ratings are usually assigned in 10% increments, such as 0%, 10%, 20%, 30%, and so on up to 100%. A 0% rating means the VA recognizes that the condition is service connected, but the symptoms are not severe enough under VA rules to qualify for monthly compensation. While that may feel frustrating, a 0% rating can still matter because it establishes service connection. If the condition worsens later, the veteran may be able to request an increased rating.

A 100% rating generally means the VA has found that a veteran’s service-connected disability or disabilities are totally disabling under VA criteria. Some veterans may receive a 100% schedular rating, while others may qualify for total disability based on individual unemployability, commonly known as TDIU, if service-connected conditions prevent them from maintaining substantially gainful employment.

Single Disability Ratings vs. Multiple Disability Ratings

Some veterans have one service-connected disability. Others have several. For example, a veteran may have a back injury, tinnitus, PTSD, knee damage, migraines, or a respiratory condition. Each approved condition may receive its own individual rating.

However, when a veteran has multiple disability ratings, the VA does not simply add those numbers together. The VA explains that combined disability ratings are calculated differently, which is why a combined rating may be different from the sum of individual ratings.

This can confuse many veterans. A 50% rating and a 30% rating do not automatically equal 80%. Instead, the VA uses what is commonly called the “whole person” approach.

The “Whole Person” Formula

The VA’s rating math is based on the idea that a person starts as 100% able-bodied. Each disability reduces the remaining portion of that “whole person,” not the original 100% each time.

For example, if a veteran has a 50% disability rating, the VA considers the veteran 50% disabled and 50% efficient. If the veteran then has another disability rated at 30%, that 30% is applied to the remaining 50% efficiency, not to the full 100%. That results in a combined value that is lower than simple addition.

This is why veterans often hear that “VA math” is not normal math. The VA uses a Combined Ratings Table to calculate multiple disability ratings. The final combined number is generally rounded to the nearest 10%.

This system can make a major difference. A veteran with multiple moderate ratings may assume they should be at 100%, only to receive a combined rating that is lower. Understanding the whole person formula can help veterans better understand their decision letter and whether the VA properly rated their conditions.

How Ratings Impact Compensation

VA disability compensation is tied to the veteran’s combined disability rating. The higher the rating, the higher the monthly payment. The VA states that disability compensation is a monthly tax-free payment for veterans who became sick or injured while serving, or whose service made an existing condition worse.

Compensation can also be affected by dependents. The VA explains that monthly payments may increase if a veteran has a spouse, child, or dependent parent and has a combined disability rating of 30% or greater. Veterans rated at 10% or 20% generally do not receive a higher rate for dependents.

Current VA compensation rates are updated periodically. The VA’s 2026 compensation table, effective December 1, 2025, lists monthly payment amounts by disability rating and dependent status. For example, the VA lists payments for veterans rated at 10% and 20%, and separate tables for veterans rated 30% to 100% depending on family circumstances.

Because rating changes can affect monthly compensation, back pay, and eligibility for other benefits, veterans should review their rating decision carefully.

What Does a 70% Rating Mean Compared to 100%?

A 70% rating can still represent serious disability. It may mean the VA has found that a veteran’s service-connected condition significantly affects work, daily life, social functioning, physical ability, or mental health. Many veterans with a 70% rating have severe symptoms and meaningful limitations.

A 100% rating generally means the veteran is considered totally disabled under VA rules. This may be based on a single condition rated at 100%, multiple conditions combining to 100%, or TDIU in some cases. The difference between 70% and 100% can be significant because it may affect monthly compensation and access to additional benefits.

However, the question is not whether a veteran “deserves” a higher number in a general sense. The issue is whether the medical evidence, symptoms, functional limitations, and VA rating criteria support a higher rating.

When to Request an Increase

Veterans may consider requesting an increased rating when a service-connected condition has worsened or when the original rating does not accurately reflect the severity of the disability.

Examples may include worsening pain, reduced mobility, more frequent migraines, increased panic attacks, worsening PTSD symptoms, new medication, additional treatment, hospitalizations, lost work time, or greater difficulty with daily activities. A veteran may also seek an increase if a condition now causes secondary conditions, such as a knee injury contributing to hip or back problems.

The VA allows veterans to file for an increase in disability compensation when a service-connected disability has gotten worse. Veterans may need to submit medical evidence showing that the condition has worsened.

Before requesting an increase, veterans should understand that the VA may review the condition. In some cases, if the VA believes the condition has improved, a rating could potentially be reduced. That does not mean veterans should avoid seeking the benefits they may deserve. It does mean they should be prepared with strong, current medical evidence.

Can a VA Disability Rating Go Down?

Yes, in some situations, a VA disability rating can go down. If the VA reviews a condition and determines that it has improved under the applicable rating criteria, the VA may propose a reduction. Veterans generally have rights in that process, including the opportunity to respond and submit evidence.

A proposed reduction should be taken seriously. Veterans should read every VA notice carefully, pay attention to deadlines, and gather medical evidence showing the true severity of the condition. If a veteran disagrees with a reduction, they may have options to challenge it.

Frequently Asked Questions

How does the VA calculate ratings?

The VA assigns disability ratings based on the severity of each service-connected condition and how much it affects the veteran’s overall health and ability to function. Ratings are usually assigned in 10% increments from 0% to 100%. When a veteran has more than one service-connected disability, the VA uses a combined ratings method rather than simple addition. This means the final combined rating may be lower than the total of the individual ratings.

Can ratings be combined?

Yes. Veterans with multiple service-connected disabilities may receive a combined disability rating. However, the VA does not simply add individual ratings together. It uses a “whole person” approach that considers each additional disability as reducing the veteran’s remaining efficiency. The resulting number is then rounded according to VA rules. This is why, for example, two separate ratings may combine to a lower percentage than a veteran might expect.

What does 70% vs. 100% mean?

A 70% rating means the VA has found that a service-connected condition or combination of conditions creates significant disability under VA criteria. A 100% rating generally means the veteran is considered totally disabled under VA rules. The difference can affect monthly compensation and eligibility for certain additional benefits. Some veterans who do not have a 100% schedular rating may still qualify for TDIU if service-connected conditions prevent substantially gainful employment.

Can my rating go down?

Yes, a VA disability rating can go down in some situations if the VA determines that a condition has improved. The VA may schedule future exams or review medical evidence to reassess the severity of a disability. If the VA proposes a reduction, veterans should pay close attention to deadlines and submit evidence showing the true severity of their condition. Veterans may have options to challenge a proposed or final reduction.

How do I increase my rating?

Veterans may request an increased rating if a service-connected condition has worsened or if the original rating does not reflect the severity of their disability. Medical records, treatment notes, prescriptions, test results, statements about daily limitations, and C&P exam findings may all help support a request for an increase. Veterans should be specific about how symptoms have changed and how the condition now affects work, daily life, mobility, sleep, or mental health.
