Need help in understanding output

I'm having problem in reading the output. I've created a piled raft foundation. I've applied load on top of raft. The load is getting transferred to soil and piles by raft. I want to find out how much of my total load is acting on soil. For this which option should I select? If I select CFT3, addition of CFT3 (Contact Force Total) for piles and soil is not equal to applied load. If I select S33 for pile bottom and pile shaft and raft bottom and calculate force by multiplying with area and add it, I'm not getting it equal to applied load.
If I select reaction forces, I'm getting reactions at support. How can I find out how much % of load is acting on soil? (Which option should I select?)
Can someone please help me

You can use contact pressure (CPRESS) output variable for that.
 
Thankyou for your reply! I am not getting it with CPRESS as output variable. The summation of loads is not equal to load calculated with CPRESS
 
It won’t be equal since CPRESS has pressure unit but you can derive forces from it (there are also separate variables for contact force output).
