Formula field calculations in Airtable

Multiplying in Airtable

Let's say you'd like to calculate the total wages for a team of hourly staff. You'll need a field to track hours (number field), another to track wages (currency field), and a final field (formula field) to enter as a formula.

{Hours Worked} * {Hourly Wage}

Subtracting in Airtable

You can accomplish similar calculations using the same formula structure when subtracting. To find the difference between wages due and wages paid, you would use a formula like the following:

{Total Wages Due} - {Total Wages Paid} 

Dividing in Airtable

In a different scenario, let's say that you're using Airtable to track your freelance project work. You quote a certain number of hours of service you will provide, and want to track your completion towards those hours.

{Actual Hours} / {Quoted Hours}

Note

To output the result of your formula as a percentage, you’ll want to be sure to click the Formatting tab in the formula field’s configuration window and select Percent under the “Format” section. Please consult the information available in this support article to learn more.
