I believe that for what you are looking for you would need to use Form Calculation widget.

With it you can do all sorts of checks and math and in the end, just pass the value that you want to use to the payment processing tool.

These are the guides that I would suggest checking out to see how this can be achieved:

How to Assign Calculation Value

How to perform calculation in the form?

How to pass a calculation to a payment field

All are simple to follow and use and if reading in given order you will see that each of them adds up to the previous one just few more details.

Do let us know if you have any questions along the way.
