## Why make calculations using Gravity Forms entry data?

Performing calculations based on Gravity Forms entries allows you to build a variety of powerful applications.

There are so many ways to utilize calculations in Gravity Forms. For example, here are some things you can build:

- Dynamic product pricing form
- Quote calculator
- Mortgage calculator
- Detailed customer survey report

Adding calculations to your Gravity Forms forms helps improve the user experience and reduces the time it takes for you to manually analyze and respond to entries.

For example, instead of writing up quotes for each customer that requests one, you could automate the process by automatically calculating the quote total based on user inputs.

## Different types of Gravity Forms calculations

There are so many ways to do calculations in Gravity Forms, including:

- Product pricing
- Form field calculations
- Calculations using a shortcode
- Displaying data and calculations on the front end
- Calculations based on conditional logic
- Date and time calculations
- Displaying data on charts and graphs
- Survey Calculations

As you can see, Gravity Forms offers a lot of functionality! If you’re feeling overwhelmed, don’t worry. We’ll cover everything you need to know in this post.

## Performing calculations in Gravity Forms (example)

Gravity Forms allows you to do basic calculations based on user input values. You can do calculations within a field by using the “Number” field.

For example, letâ€™s build a form that can calculate the area of a circle based on its radius. We’ll start by creating a new form in Gravity Forms. We can do this by hovering over “Forms”* *and clicking on “New Form”.

Next, we’ll add a “Number”* *field to the form, called â€śCircle Radiusâ€ť. After that, we’ll add another “Number”* *field below the first one called â€śCircle Areaâ€ť, and click â€śPublishâ€ť to save our form.

Under “Field Settings”, we’ll check the box that says â€śEnable Calculationâ€ť. In the box below, weâ€™re going to insert our formula. To calculate the area of a circle, you multiply pi (~3.14) by the square of the radius.

As you can see, weâ€™re using a merge tag to reference the user input value from the first field. Then weâ€™re squaring it and multiplying it by 3.14.

After writing our formula, we’ll check that itâ€™s valid by clicking “Validate Formula”.

Hereâ€™s what our form looks like on the front end. When a user inputs the radius of their circle, Gravity Forms automatically calculates the area and displays it in the Circle Area field.

This is just one small example of how to use calculations in your Gravity Forms.

## Gravity Forms product pricing calculations

When selling products on your website, itâ€™s helpful to be able to calculate shipping costs, discounts as well as other metrics such as average order value.

Product calculations are built into Gravity Forms, but if you want to take things further youâ€™ll need to install one or more plugins. See the articles below for more guidance on performing product pricing calculations:

## Gravity Forms advanced calculations using GravityMath

GravityMath is a WordPress plugin that allows you to do advanced calculations on your website. The plugin integrates seamlessly with Gravity Forms, allowing you to:

- Perform complex functions
- Count the number of entries in a form (values are always up to date)
- Display calculations anywhere on your WordPress site
- Perform calculations based on conditional logic
- Perform calculations based on product pricing fields

After activating the plugin, youâ€™ll be able to use the `[gv_math]`

shortcode to perform advanced calculations on your website.

The `[gv_math]`

shortcode also supports several mathematical functions and constants for all types of advanced calculations.

You can also use the `[gv_math]`

shortcode inside your WordPress pages and posts; values will update dynamically when new data is added!

- Adding advanced calculations to blog posts
- Creating complex calculations using nested shortcodes in GravityMath

## Performing advanced Gravity Forms calculations in GravityView

GravityView is an add-on for Gravity Forms that allows you to display your form data on the front end and build powerful, form-based web applications. GravityMath integrates with GravityView, enabling you to add calculations to tables containing form submission data, or anywhere inside a View.

## Gravity Forms date and time calculations

Are you wondering how to do date and time calculations in Gravity Forms? In order to perform date and time calculations inside your forms, you’ll need the Date Time Calculator add-on by Gravity Wiz.

After activating the add-on, go to Gravity Forms and create a new form with one or more “Date” or “Time” fields.

Now add a “Number”* *field to your form and check the box to enable calculations. Inside the text box, you can add date and time field merge tags into your calculations!

In this example, we’re subtracting the start date from the end date, to get the number of days between the two dates.

This add-on allows you to change the calculation units, count the number of weekdays between dates, and much more.

## Gravity Forms calculations based on conditional logic

If you have GravityView installed along with GravityMath, you can combine two very powerful shortcodes to perform calculations based on conditional logic.

The GravityView conditional logic shortcode, called `[gvlogic]`

, allows you to display information based on parameters that you set. You can use the `[gv_math]`

shortcode inside `[gv_logic]`

to create complex formulas.

Hereâ€™s a brief overview of how it works:

```
[gvlogic if="{product:6}" is="Option One"]
Total cost: [gv_math] 100 + 50 [/gv_math]
[else]
Total cost: [gv_math] 75 + 50 [/gv_math]
[/gvlogic]
```

Using `[gvlogic]`

you can set up different conditions, so your formula will return different results depending on the information submitted by the user.

## Creating charts from Gravity Forms entries using GravityCharts

Today, businesses rely on graphs in order to visualize large amounts of data in a meaningful way. If youâ€™re using Gravity Forms to collect information on your website, you may be wondering how to extract that data from the database and visualize it using graphs and charts.

You can do this using GravityCharts, a powerful add-on for Gravity Forms that allows you to create charts without writing any code!

## Gravity Forms survey calculations

A survey is an important marketing tool that allows you to learn more about your customers. If you want to conduct surveys on your website using Gravity Forms, you can use the Gravity Forms Survey Add-On.

The survey add-on also integrates with GravityView, allowing you to display surveys on the front end of your website. And if your surveys have scoring enabled, you can use GravityMath to display footer calculations based on survey results.

To create your first survey, start by installing the Gravity Forms Survey add-on. Next, create a new form and add a Survey field.

Under “Field Settings”, check the box that says â€śEnable Scoringâ€ť.

Youâ€™re all set!
