Charge the User/App Fee Calculation

So I want to double check my formula for calculating the “app fee” within the “Charge the Current User” workflow…

My marketplace allows users to sell services at an hourly rate. I want to charge the “seller” 5% per transaction. So my Charge the User/App Fee calculation looks something like this:

Current Page Seller’s Service 1 Price * 2 * 0.05

Service 1 Price ( a number) is the service cost
2 is the number of hours purchased
.05 is the app fee

Is this the correct way to calculate the app fee?

Cheers!

That looks good to me, but you should use the interactive debugger to see what gets calculated in execution.
