Adding formula fields in Airtable
Adding formula fields
Formulas allow you to output numbers, dates, strings, and more in each record based on static or dynamic information from other cells in that same record. For example, if you have a table of product orders, you can create a field that computes the Total Cost for each record based on the Price and Quantity.
Visit your Airtable homepage.
Create or open your preferred base.
Search for and select Formula.
From there, you can enter the formula into the text box as you would in a spreadsheet, except you use the names of fields instead of cell ranges. A formula can comprise functions (e.g., SUM, CONCATENATE), operators (e.g., +, -, *, /, &), and other fields from the same table.
Suppose your formula will result in a numerical output. In that case, you can format the formula's result as a decimal, an integer, a currency, a percent, or a time duration. Additionally, you can adjust the precision for decimals, currencies, and percentages.
Enter your formula in the space under “Formula.”
Click Create field.

Formulas versus other computed fields in Airtable
Formulas versus other computed fields overview
Computed fields are unique field types where field values are calculated by Airtable automatically rather than directly edited by users. These fields allow you to tally a value based on values in other fields—like formula, lookup, count, and rollup—or fields that return the same values independently of other fields in the table or user actions—like auto number or created time.
Computed field types are slightly different from formulas in a spreadsheet. In a spreadsheet, you can put a formula in any cell and have it reference any other cell in the sheet. In Airtable, you configure computed fields that apply the same formula to every record in the table. As a result, these formulas reference other fields rather than other cells so that they apply to every record.
Rollup, lookup, and count fields can only be used when you have a linked record field in your table.
