Understanding VA Disability Ratings: A Veteran's Plain-Language Guide

What a VA disability rating actually is

A VA disability rating is a percentage — from 0% to 100%, in 10% increments — that reflects how severely a service-connected condition affects your earning capacity and daily life. It determines your monthly compensation and unlocks access to other benefits like healthcare priority groups, dependent benefits, and certain state programs.

How ratings are decided

The VA uses the Schedule for Rating Disabilities (VASRD) — a published rulebook that maps medical evidence to percentages for each body system. Raters look at:

• Medical evidence (VA exams, private records, service medical records)
• Lay evidence (your statements, buddy letters, family observations)
• Severity and frequency of symptoms
• Functional impact on work and daily life

The clearer the evidence ties a current condition to service, the smoother the decision.

The math: why 30% + 20% does not equal 50%

The VA does not add ratings the way you'd expect. It uses combined ratings tables that account for the fact you only have 100% of a person to begin with. A 30% rating plus a 20% rating combines to roughly 44%, which rounds to 40%.

This is why pursuing every legitimate condition matters — small ratings compound, but slowly.

What your rating unlocks

• Monthly tax-free compensation at the rate set for your percentage (and dependents, at 30%+).
• VA healthcare priority group placement.
• Vocational rehabilitation eligibility (VR&E) for many veterans.
• Property tax exemptions and other state benefits in many states.
• CHAMPVA / dependent education benefits at higher ratings.

How to strengthen a future claim

1. Get a current diagnosis from a qualified provider.
2. Document symptoms over time — a simple journal helps.
3. Identify in-service events, exposures, or injuries that connect to the condition.
4. Gather supporting statements from people who've seen the impact.
5. Use a structured tool like ClaimPrep Vet to organize everything before you file.

The system is dense, but it's navigable. Preparation is what changes outcomes.
