If your VA disability rating feels lower than it should be — you’re probably right.
Every year, thousands of veterans walk away from the VA system underrated. Not because they exaggerated their conditions. Not because they did something wrong. But because the VA disability system is complicated, the paperwork is exhausting, and nobody handed you a guide when you separated.
The good news? Your rating is not set in stone. You can file for an increase. You can claim conditions you missed. And you can get the monthly compensation you actually earned.
This guide breaks down exactly how VA disability ratings work, why so many veterans end up underrated, and what concrete steps you can take right now.
What Is a VA Disability Rating?
A VA disability rating is a percentage assigned by the Department of Veterans Affairs that reflects how much your service-connected conditions affect your ability to work and live your daily life.
Ratings go from 0% to 100% in increments of 10. The higher your rating, the more tax-free monthly compensation you receive.
Here is what the monthly compensation looks like in 2026:
| Rating | Monthly Payment (Approx.) |
| 10% | ~$175/month |
| 30% | ~$524/month |
| 50% | ~$1,102/month |
| 70% | ~$1,716/month |
| 100% | ~$3,831/month |
That gap between a 50% and 70% rating is more than $600 every single month — tax free. Over a year, that is over $7,000. Over a decade, that is more than $70,000.
If your rating is even one tier lower than it should be, you are leaving real money on the table every month.
How VA Disability Ratings Are Calculated
Here is where most veterans get confused — and where the system works against you if you do not understand it.
Single condition ratings
If you have one service-connected condition, the VA assigns a single percentage based on the severity of that condition. A 30% rating for PTSD, for example, means the VA has determined that your PTSD moderately affects your occupational and social functioning.
Combined ratings — the “VA math” problem
If you have multiple service-connected conditions, the VA does not simply add your percentages together. They use a method called the whole person formula — which almost always produces a lower number than you would expect.
Here is how it works:
- Start with 100% — your whole body
- Apply your highest-rated condition first. Say it is 50%. That leaves 50% remaining.
- Apply your next condition (say 30%) to the remaining 50% — not to 100%. So 30% of 50% = 15%.
- Your combined total is now 65%, which rounds down to 60%
A veteran with a 50% condition and a 30% condition ends up rated at 60% — not 80%.
This is called VA math. It consistently produces lower combined ratings than veterans expect, and it is one of the main reasons so many veterans are undercompensated.

6 Reasons Your VA Disability Rating May Be Too Low
1. You only claimed your most obvious condition
This is the most common mistake veterans make. You filed for your knee injury and stopped there. But what about tinnitus from combat noise exposure? Sleep apnea linked to your PTSD? Migraines from a TBI? Each condition you did not claim is compensation you are not receiving.
2. Your C&P exam did not reflect your worst days
The Compensation and Pension (C&P) exam is one of the most critical steps in the VA rating process — and one of the most misunderstood. Many veterans show up to their C&P exam, minimize their symptoms out of habit, and walk out underrepresented in the official record. The VA examiner sees you once. If you had a good day, your file may not reflect how your condition actually affects your life.
3. You never filed for secondary conditions
A secondary service-connected condition is one that was caused or aggravated by an existing service-connected condition. These are ratable separately — and most veterans have no idea this is an option.
Examples:
- Knee injury → altered gait → hip or back pain → separate rating
- PTSD → sleep apnea → separate rating
- Diabetes (service-connected) → peripheral neuropathy → separate rating
Every secondary condition you have not filed for is a missed rating opportunity.
4. Your condition has gotten worse
VA disability ratings are not permanent. If your service-connected condition has worsened since your original rating was assigned, you can file for an increase with new medical evidence. Many veterans assume that once a rating is set, it cannot change. It can — and it should if your health has declined.
5. Your nexus letter was weak or missing
A nexus letter is a statement from a medical professional connecting your current condition to your military service. It is often the difference between a claim being approved and denied. Without a strong nexus letter, the VA has less evidence to rate you accurately.
6. You did not know about TDIU
Total Disability Individual Unemployability (TDIU) is a benefit that allows veterans rated at 60% or higher — or 70% or higher with one condition at 40%+ — to receive compensation at the 100% rate if their service-connected conditions prevent them from maintaining substantially gainful employment.
If your disabilities prevent you from holding a steady job, you may qualify for full 100% compensation even without a 100% rating. This is one of the most underused benefits in the entire VA system.
How to File for a Rating Increase
You do not need a lawyer. You do not need to pay anyone. Here is the process:
Step 1 — Gather your evidence
Collect all relevant medical records, doctor statements, buddy statements from fellow veterans or family members who can attest to how your condition affects your daily life, and your own personal statement describing your worst-day symptoms.
Step 2 — Choose the right filing path
There are three options depending on your situation:
- Supplemental Claim — if you have new and relevant evidence that was not considered in your original decision
- Higher-Level Review — if you believe the VA made an error in your existing claim (no new evidence needed)
- New Claim — if you are adding a condition you never filed for
Step 3 — File VA Form 21-526EZ
This is the standard disability compensation application. You can file online at VA.gov, by mail, or in person at a VA regional office. Filing with a VSO (Veterans Service Organization) is free and they can help you submit a stronger claim.
Step 4 — Prepare for your C&P exam
If the VA schedules a C&P exam, attend it. Describe your worst symptoms, not your average day. Bring a written summary of how your condition affects your work, sleep, relationships, and daily activities. Do not minimize.
Step 5 — Follow up and appeal if needed
VA claims can take several months to process. Check your claim status regularly. If you receive a decision you disagree with, you have one year from the decision date to file an appeal.

The Bottom Line
Your VA disability rating is not final. The VA makes mistakes. Conditions get missed. Evidence gets overlooked. And the system was not designed to make this easy.
But you have options. You can file for an increase. You can claim secondary conditions. You can appeal decisions. And you can get the monthly compensation that reflects what your service actually cost you.
The first step is knowing where you stand.
