Looking for a form that modifies product pricing

Does anyone know if there is a solution to the following?

I am looking to add a form, checkbox or drop-down to customize a base-product. This is easy enough. However, we want the selected options to affect price.

Example: Add-ons. Select up to five

Option 1 (adds $10), Option 2 (adds $15), etc.

Even better would be a percent price increase. I know this can be done by adding complex variants, but, considering the extensive amount of combinations this adds, that would prove very cumbersome. Ideally we would have a couple options as variants like substyle and size, but other customizations to the product as part of a form.

Thanks for your help

Hi, I also need to do this on my site. Did you ever find a solution?

This is possible with code @bbsbeer but it will rely on complex variants which, as you mentioned, are cumbersome to set up when you have lots of them. There's a similar thread here:
