When You Might Need to Do Gravity Forms Calculations

Whether you’re an online store owner, run a membership website, or organize events, there are many scenarios in which you might need to do Gravity Forms calculations on your WordPress website. Here are some of the most popular use cases:

Use Case #1: Calculating Tax or VAT

You can use Gravity Forms to automatically calculate the sales tax or VAT (value added tax) at checkout for any transaction. For example, if you have a field for the product cost and you’re collecting a 5% sales tax, you could use the formula:

Total sales tax = Item cost * Sales tax Total item cost = Item cost + Total sales tax

Alternatively, you could use Gravity Forms eCommerce Fields plugin to add a Tax field to your form – more on this later.

Use Case #2: Offering Early Bird Discounts

Another way to use Gravity Forms calculations is if you need a way to offer discounts for a specific date range. This is useful for people who sell online courses, memberships, or event tickets. For example, if you want to offer early bird pricing to registrants who register for your event between December 23rd and January 10th.

Simply put, you can do all sorts of simple and advanced calculations on forms fields and user submissions. The Gravity Forms plugin lets you do calculations using a Number field with calculation enabled.

Case Study: Conference Registrations

Michelle Hayes uses Gravity Forms calculations for offering attendees an early bird discount during conference registration without using a coupon code. She was able to do this using the Gravity Forms Conditional Logic Dates and Gravity Forms Conditional Pricing add-ons.

• Automatically calculating early bird price using Gravity Forms Conditional Logic Dates and Gravity Forms Conditional Pricing.
• Dynamically offer multiple types of discounts with a single discount code field using Gravity Forms eCommerce Fields.
• Directing registrants to the All-Access Pass if they’d like to register for all events using Gravity Forms Limit Checkboxes. This way, registrants don’t have to check all of the individual events; they can just choose an All-Access option.

As a result, Hayes was able to deliver an enhanced user experience to registrants. The same approach can be used to offer limited-time discounts for event tickets and memberships.
