Benefits by Disability Percentage
What each rating level means — and how combined ratings really work
VA ratings are not additive. Understanding the combined ratings table — and what benefits attach at each level — explains why 50% plus 30% does not equal 80%.
VA Math Is Not Regular Math
The VA does not add your ratings together. It uses the combined ratings table in §4.25, which works on the principle of whole-person efficiency: each additional disability is applied only to the portion of you that is still considered non-disabled. That is why 50% and 30% combine to 65 — rounded to 70% — not 80.
Walk it through. Start at 100 percent efficient. A 50% disability leaves you 50 percent efficient. The next disability, rated 30%, takes 30 percent of that remaining 50 — which is 15. Add the 15 to the 50 and you get 65. Round to the nearest 10 and the combined rating is 70%. Every additional condition is worth less than its face value, which is why order of operations — always highest first — matters.
A Worked Example
PTSD. Start at 100% efficiency; 50% of 100 = 50. Running total: 50. Remaining efficiency: 50.
Lumbar strain. 30% of the remaining 50 = 15. Running total: 65. Remaining efficiency: 35.
Radiculopathy, right lower extremity. 20% of the remaining 35 = 7. Running total: 72. Remaining efficiency: 28.
Tinnitus. 10% of the remaining 28 = 2.8. Running total: 74.8.
Final combined value 74.8 rounds to the nearest 10 — a combined rating of 70%. Four disabilities totaling 110 on paper pay at 70.
What Attaches at Each Level
0% (non-compensable)
Service connection is established but no monthly payment. Still valuable — it locks in the connection for future increases, supports secondary claims, and under §3.324 two or more 0% conditions that clearly interfere with employability can support a single 10% rating.
10–20%
Monthly compensation begins. No dependent add-ons at this level. VA health-care priority improves.
30% and above
Additional compensation for dependents — spouse, children, and dependent parents. File VA Form 21-686c; this is routinely forgotten and back pay for it is limited.
50%
Placement in VA health-care Priority Group 1 territory, with copays for service-connected care generally eliminated.
60% / 70%
The §4.16(a) TDIU thresholds — one condition at 60%, or combined 70% with one at 40%. Many state benefits also key on 70%.
100% and P&T
Maximum schedular compensation, plus CHAMPVA, Chapter 35, commissary and exchange access, housing and auto grants, and — in many states — full property-tax exemption.
The Bilateral Factor — the Piece the VA Forgets
When disabilities affect both arms, both legs, or paired skeletal structures, §4.26 requires the VA to combine those bilateral disabilities first, then add 10 percent of that combined value as a bilateral factor, and only then combine the result with everything else. It exists because losing function on both sides is more disabling than the sum of two one-sided losses.
It is easy to overlook and easy for the VA to omit. If you have paired-extremity conditions — both knees, both feet, bilateral radiculopathy, both shoulders — read your code sheet and confirm the bilateral factor was applied. A missing bilateral factor is one of the cleanest, most provable rating errors there is.
Pyramiding and Its Limits
Section 4.14 prohibits pyramiding — rating the same disability manifestation twice under different diagnostic codes. But it does not prohibit separate ratings for distinct manifestations. A service-connected knee can carry separate ratings for limitation of motion and for instability, because those are different symptoms. A spine condition can carry separate ratings for the spine itself and for each radiculopathy in the extremities.
Where veterans lose money is the reverse error: the VA lumping distinct disabilities under one code. Reading your rating decision code sheet for missed separate ratings is often worth more than fighting for a higher percentage on any single one.
The Advocate’s Take
If you have ever done the addition and wondered why your number came out lower, now you know. The bilateral factor and missed separate ratings are the two places we find money most often — both are on your code sheet, in writing.
Where the VA Gets This Wrong
Omitting the §4.26 bilateral factor; combining in the wrong order; and refusing separate ratings for genuinely distinct manifestations by mislabeling them as pyramiding under §4.14.
Every Level the VA Can Assign You
These percentages come straight out of the rating schedule that governs benefits by disability percentage — the governing diagnostic code. Read them slowly. If your current rating does not match what your records actually show, that gap is exactly what an appeal exists to correct.
50%
PTSD.
30%
Lumbar strain.
20%
Radiculopathy, right lower extremity.
10%
Tinnitus.
70%
Final combined value 74.8 rounds to the nearest 10 — a combined rating of **70%**.
Building a Benefits by Disability Percentage Claim That Wins
Every claim stands on three legs. Knock one out and the claim falls over, no matter how bad your symptoms are. Before you file, look at your file and find all three.
A current diagnosis
A doctor has to say you have it, now, in writing. Not "reports symptoms of" — a diagnosis. Without this leg, nothing else in the file matters.
A link to your service
An event, an injury, an exposure, or an already service-connected condition. Service records, unit records, buddy statements, and your own account all count as evidence.
A nexus that ties the two together
A medical opinion stating it is at least as likely as not that your service caused or aggravated the condition. That phrase is a legal standard: 50 percent or better. It is the leg most denials break.
Document the problem before you file
• Keep a dated symptom log for at least 30 days. Frequency, severity, and what it stopped you from doing.
• Get statements from people who see it — a spouse, a coworker, a battle buddy. Lay evidence is legal evidence.
• Pull your private treatment records. The VA only has to help; it does not have to go find everything.
• Write down what you have stopped doing. Lost work, lost sleep, lost activities. That is what impairment looks like on paper.
Your Rights in This Process
It costs nothing to file
Filing a VA claim is free. Accredited representatives may only charge for work on an appeal after an initial decision, and those fees are capped by 38 CFR §14.636.
The VA has a Duty to Assist you
Under 38 CFR §3.159 the VA must help you get the evidence it needs, and it must tell you what is missing before it denies you for missing it.
You can ask for a different examiner
You may request a trauma-informed clinician, or a clinician of a specific gender, for a C&P examination. Ask before the exam is scheduled.
You can claim every condition you have
There is no limit and no penalty. Primary conditions, secondary conditions, and conditions made worse by service all get filed.
You can appeal and be re-evaluated
A denial is not the end. You may submit new evidence, request a higher-level review, appeal to the Board, and ask for re-evaluation when your condition worsens.
You must be considered for TDIU
If your service-connected conditions keep you from holding substantially gainful employment, you may be paid at the 100 percent rate without a 100 percent rating.
When You Are Ready to File

Most benefits scale with your combined disability rating — and the VA does not add your ratings the way you would expect. Work the real math below.
Why 50% + 30% Does NOT Equal 80%
The VA uses “whole-person” math, not simple addition. This is how ratings really stack.
The VA always begins from a whole, healthy person (100%).
50% of 100 is subtracted. You have 50% “efficiency” left.
30% is taken from the REMAINING 50 (0.30 × 50 = 15). 50 − 15 = 35 left.
100 − 35 = 65, then rounded to the nearest 10 → 70%.
Bottom line: two 50% ratings combine to 75% → rounded to 80%, not 100%. Every rating you add is worth less than the last. That is why which conditions you claim — and in what order — matters as much as how many.
