Possible to change value of text based on droplist and stepper selection?

Hi!
I’m trying to see if I can build a somewhat semi-functional prototype here.
Basically I have steppers and droplist on a page, and a Number. I want to change the value of that Number based on the stepper dropdown options selected.
I’m having trouble figuring out how to set a variable to the Number, then change that variable when stepper and dropdown options change.
Any help is appreciated!

I’m not totally sure I understand how the values in your screenshot are supposed to relate to each other, but I’m gonna assume it’s an insurance payment calculator. Here’s an example that’s hopefully enough to get you started:
