Can you give me any tips to help me figure the rating out?
Yes, look for your highest disability rating in the left column and your lowest rating in the top column and your combined rating is the number where the two intersect , rounded to the nearest 10%.
In step 4 how do you figure out the combined disability rating?
We will round combined values ending in 1 to 4 down, and those ending in 5 to 9 up.
