Hello,
If you want a direct calculation what you need is to do in with some js and then fill a field with this value. Computed field do the math with php and it seems you want to do it in frontend.
It typically works I can do as I'm full stack developer. I think it's a matter of one day of work. I'll need to make a custom module with some js inside. Then we put the value in a integer field (no more need of computed field).
Contact me if interested,
Thanks,
