    We have the calculation feature, kindly check this guide: How to perform calculation in the form?. However, we only support a few fields with numeric values.

    The formula should be easy, you can find the steps from the guide provided. So based on your preference, the calculation formula would be:

    [{pricefield} * 0.20}] - number input to the field multiplied by 20%
