Show and update a formula within a form?

[Erin_Keeffe]

I’m setting up a custom ordering form for a family business, where the options that a customer picks will determine some end results like total price, total items, and/or fulfillment time estimates.

I’m wondering if there is a way to show a formula field within a form to accomplish this.

As a very basic example I might have:

• 3 number fields
• 1 formula field that sums the 3 number fields
• A form that allows users to fill in the 3 number fields

I would like for the customer to be able to see the total (formula sum-ing the three number fields) in real-time as they fill out the form, just as I would if I was creating a new record and filling it in inside of the grid view in Airtable.

Is this possible or is there another way to accomplish this?

This can't be achieved using Airtable form. But it can be done with external tools. If you want to create a purchase order form, you can use miniExtensions. It supports showing computed fields on the form (like rollups for total price). Here's how the option looks:
