Showing auto calculated values in Input field or text box on key up using html & js.

This is exactly what I have been searching for, but my use case is work related. I want to create a formula in which the user only enters 5 piece of info and using a simple formula it gives output. I don't know anything about coding or stuff but I can edit html as per my needs and I have done this in the past. Can you please give me this code so that I can make changes to incorporate it in my html. Thanks in advance

Thank You for this simple code.
How can we make it to multiply or divide according to selection from a dropdown ?

Can you share the code? I'm a basic user of html and I've been trying to create a calculator very similar to yours where an input will calculate another by a specific factor and I can't get the calculating field to work so if I figured if I can start with your example, I can build the rest of the calculator. I just need the functionality to work.
