Combined Ratings Table (Table I, 38 CFR 4.25)
This is the complete combined ratings table, exactly as published in the regulation. To use it the way VA does: arrange your disabilities in order of severity, greatest first. Read the degree of the first disability in the left column and the degree of the second across the top; the number where they meet is the combined value. If you have more disabilities, take that combined value back to the left column and repeat with the next disability. Convert to the nearest multiple of 10 only once, at the very end, with values ending in 5 adjusted upward. (The table starts at 19 because the smallest possible combination, 10 combined with 10, is 19. A single disability, or a running value below 19, combines by the same formula the table is built from: a + b x (100 - a) / 100.)
Try it against the calculator: 50 in the left column, 30 across the top, gives 65, which converts to a 70% rating.

Table I, 38 CFR 4.25. The table results from the consideration of the efficiency of the individual as affected first by the most disabling condition, then by the less disabling condition, then by other less disabling conditions, in the order of severity.
Reading examples from the regulation itself
- 60% and 30%: 60 leaves 40% efficiency; 30% of that 40 is 12, so the combined value is 72, a 70% rating.
- 50% and 30%: combined value 65, converted upward to 70%.
- 40% and 20%: combined value 52, converted to 50%.
- 60%, 40%, and 20%: 60 and 40 combine to 76; 76 and 20 combine to 81, converted to 80%.
