VA combined rating calculator

VA does not add ratings, it combines them, and this shows the math VA uses.

Nothing here is stored and nothing is sent anywhere. The math runs on your own device. The button above carries only the ratings you chose, in the web address.

The rule

These are the sentences the calculator follows, quoted word for word. Both sections say more than this, so read them in full at the links.

How the VA does this math, in plain words walks the same rule one step at a time, with the worked examples the regulation prints.

Combining ratings, 38 CFR 4.25

Table I, Combined Ratings 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, if any, in the order of severity.

To use table I, the disabilities will first be arranged in the exact order of their severity, beginning with the greatest disability and then combined with use of table I as hereinafter indicated.

This combined value will then be converted to the nearest number divisible by 10, and combined values ending in 5 will be adjusted upward.

The conversion to the nearest degree divisible by 10 will be done only once per rating decision, will follow the combining of all disabilities, and will be the last procedure in determining the combined degree of disability.

The bilateral factor, 38 CFR 4.26

Except as provided in paragraph (d) of this section, when a partial disability results from disease or injury of both arms, or of both legs, or of paired skeletal muscles, the ratings for the disabilities of the right and left sides will be combined as usual, and 10 percent of this value will be added (i.e., not combined) before proceeding with further combinations, or converting to degree of disability.

The bilateral factor will be applied to such bilateral disabilities before other combinations are carried out and the rating for such disabilities including the bilateral factor in this section will be treated as one disability for the purpose of arranging in order of severity and for all further combinations.

The bilateral factor is not applicable unless there is partial disability of compensable degree in each of 2 paired extremities, or paired skeletal muscles.

In cases where the combined evaluation is lower than what could be achieved by not including one or more bilateral disabilities in the bilateral factor calculation, those bilateral disabilities will be removed from the bilateral factor calculation and combined separately, to achieve the combined evaluation most favorable to the veteran.

This page gives a rating, not an amount of money. VA publishes what each combined rating pays at va.gov/disability/compensation-rates/veteran-rates. Your own rating is whatever VA decides, and only VA decides it.
