Is it possible to show the calculation values on a form for multiple choice fields?

You can use the guide above, assign calculation values to the multiple-choice field options and then use a Form calculation widget to add them: https://www.jotform.com/help/259-how-to-perform-form-calculation-using-a-widget/

Is that what you are referring to?

OR do you want to show that value on the choice itself? If yes, you can show the value along with the option text.

If you are referring to something different please let us know.
