Navy89 posted a question in VA Disability Compensation Benefits Claims Research ForumI was calculating 'my already calculated' disability on http://www.vvaarizona.org/combined_disability.php# with their calculator. When I enter the number of rated disabilities (7) add 6 10% individually then my last of 30%, I get 62.7%....basically 60%. I am officially rated at 70% . The only way I get 70% on the calculator is if i add the 6 10% for 60% and add 30% and then calculate...72% for 70%. Which way is correct? If the first way is correct, has anyone ever had to pay back pay if they miscalculated? Like, 10% for over 9 years?
