    1. After adding a formula, you can optionally click Format to customize your formula's results.


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.
