How to Read a VA Disability Rating Chart Correctly
What the Grid Actually Represents
The combined ratings chart looks intimidating, but it rests on one idea: no rating is ever worth its full face value once another rating exists. Each percentage is applied to what remains of you after the previous disabilities. The chart simply pre-computes that process for two ratings at a time. A va disability calculator chart presents the same grid in a cleaner form, with the paired result shown before any rounding, so you can follow the chain yourself instead of trusting a single finished number.
Work in Descending Order
Always start with your largest rating and combine downward. Find that rating on the chart’s axis, pair it with your second-largest rating, and note the result. Then treat that result as your new starting figure and pair it with the third rating, and so on. Order does not change the final mathematics, but descending order is the VA’s own convention and makes errors easier to spot. Round only once, at the very end: combined values ending in 5 or above round up to the next ten, and values below 5 round down.
Do Not Forget the Bilateral Factor
The plain chart does not show the bilateral factor. When disabilities affect both arms, both legs, or a paired set of muscles, the VA combines those particular ratings first, then adds 10 percent of that combined value before merging the result with everything else. It is a small adjustment, but at rounding boundaries it can be the adjustment that lifts a 94 to a payable 100, so any manual chart work should flag bilateral conditions before the general combination begins.
Pair the Chart With Your Family Situation
The chart gives you a rating, not a paycheck. Two veterans with the same 70 percent rating can receive different amounts because one has a spouse and children. After the chart gives you a combined figure you trust, finish the job with a va disability calculator with dependents so the dependent additions for ratings of 30 percent and above are included. Rating first, payment second: that order keeps the estimate honest and makes any later discrepancy easy to trace.
A Worked Example, Step by Step
Take ratings of 40, 30, and 10 percent. Start with the 40: it leaves 60 percent of you efficient. The 30 percent rating applies to that 60, contributing 18 points, so the combined value is 58 and the remaining efficiency is 42. The 10 percent rating then applies to the 42, contributing 4.2 points, for a final combined value of 62.2. Only now do you round: 62.2 becomes a 60 percent rating. Notice what the example teaches: the 10 percent condition, real as it is, moved the combined value by barely four points, and the rounding step at the end erased most of even that.
The Mistakes That Produce Wrong Totals
The most common error is adding the percentages directly, which overstates everything. The second is rounding after each pairing instead of once at the end. The third is starting with the smallest rating and misreading which axis holds which figure, which produces a pairing the chart never intended. The fourth is forgetting that the chart knows nothing about the bilateral factor, dependents, or payment rates. Treat the chart as one instrument in a kit: superb for the combination step, silent on everything that comes before and after it.
With a little practice, a full manual check takes under five minutes, and it turns the combined rating in a decision letter from an assertion you accept into a number you have personally confirmed.
Keep Your Worksheet
When you finish a manual combination, do not throw the worksheet away. Note the date, the ratings you used, and the result, and file it with the decision letter it came from. At your next claim, that sheet becomes the baseline: the new estimate starts from a combination you have already proven rather than from memory. If a future decision produces a combined rating that your updated worksheet cannot reproduce, you will know immediately, and you will have the workings ready to show anyone reviewing the case. In a system run on paper and percentages, the veteran with the tidy file holds a quiet advantage.
