Is there a ready-made software solution - a custom panel for changing parameters and the calculation of the result in the same place?

Question

Windows

An example of what I'm looking for is to go to the bank's website where you can select the loan amount, loan terms with the sliders, and the site will show you at the bottom the allowable amount of the monthly payment.
The question is - is there a site where you can set up a number of such "sliders" yourself and specify the calculation of the result depending on the values ​​selected by the user with a formula? Or do you have to write?
Roughly speaking, I have 4 variables, each varies within 10 different values. These values ​​are used to calculate the result. All this can be done in Excel, but you need to be careful. Preferably as I described above. Thanks for the help!

Well, there are calculator designers, like that topic? But they are for embedding on your site...
