Disability Rating Calculator

Use the VA Disability calculator below to see how the VA calculate your individual claims rating to get to an overall rating. The VA uses the percentage method to determine your rating and not the raw number. So, 30% + 30% does not equal 60%. If the initial rating 30% then that equals 30. But if the next rating is 30% then that becomes 30% of 70 which is 21. So, the overall score becomes 50% with a raw score of 51.
