How to show a calculated field, yet prevent user from editing?

If you take a look at our form indicated below, you can see that I have several fields that help me with various calculations needed in our form. Most of them are hidden but a couple are showing so that the registrant can see what their discounted total will be.

I am wondering how I can make it so that the "Discounted Total" will show for the registrant, yet IMPOSSIBLE FOR THEM TO EDIT.

At the moment, they are able to edit this field, which in turn alters the amount that gets charged to their credit card.

Thank you so much for your help.

Hello,

Generally, a field can be made 'Raed-Only' via field's properties. But, if you are referring to a calculation widget, please review the screenshot below on how to make it uneditable:
