It is very easy to figure out what you are going to get. First look up 70%, with your number of your dependents on the VA compensation chart. This will be your max payable CRSC. Next take your Years of Service (YOS) and multiply by 2.5. This will give you your maximum amount of retirement you would get by YOS. Now multiply that percentage by your high three salary average. This will tell you how much per month your retirement pay would be based on YOS. Last step is to take the max payable CRSC that you figured out in the first step. This money will apply to the YOS retirement dollar for dollar. It will look like this:
70% = $1505 (based on you, spouse, and one dependent)
7 X 2.5 = 17.5%
0.175 X $3000 (Use your own high three) = $525 (this would be your DOD retirement based on YOS)
$1505 is applied dollar for dollar against what your YOS retirement pay would have been. This means your CRSC pay would be $525
CRSC is not based on disability percentage. It is always figured on what you make based on years of service. CRSC cannot exceed what you would have made on years of service. The VA compensation table is used to figure what your max that can be used to offset lost YOS retirement dollars.
If you use the formula above, you will be able to figure out what your CRSC payment will be. Just remember where I put $3000 to change it to what your high three average was during your service. You also need to find your dependent situation on the VA compensation tables for 70%
Hope this helps.
