Creating formula fields in Airtable
Creating formula fields
Visit your Airtable homepage.
Create or open your preferred base.
Add or edit a field.
Search for and select Formula.
Enter your formula in the provided space below "Formula."
After adding a formula, you can optionally click Format to customize your formula's results.
NOTE
Keep in mind that all formulas yield a number, date, or text results—with individualized ways to be applied.
Number formats
When the output of a formula is a number, you can format it by double clicking the field name, selecting customize field type, and then selecting formatting. Then, you can apply the following options to the output of your formula:
Decimal
Integer
Currency
Percent
Duration
Date formats
When the output of a formula is a date, you can apply the following options to the output of your formula:
Date format (local, friendly, US, European, ISO)
Include a time field
Use the same time zone (GMT) for all collaborators
Text formats
When the output of a formula is text, that means that it potentially contains a mix of dates, numbers, and/or other plain text. Since there isn't a single way to format this information, you'll see a note in the formatting tab to notify you.
Formula terminology
Formulas in Airtable utilize terms (e.g. "String") and symbols (e.g. "&") common to programming languages, however they are simplified to make formulas easier to write and understand. The table below lists the terms you'll encounter and some common examples of each one.
