# Feed Actions: Calculate

LitCommerce Feed Management offers multiple rules when setting up your feed, enabling you to locate, modify, and optimize your product data for the target platform.

This article introduces you to the “Calculate” action.

## <mark style="color:$primary;">**Set up and apply**</mark>

For more details on how to set up and apply the rule, refer [HERE](https://litcommerce.gitbook.io/litcommerce-helpdesk/feed-management/feed-basics-and-setup/feed-setup/feed-create-and-set-up-your-feed/feed-rules).

## <mark style="color:$primary;">**How it works**</mark>

The “Calculate” action appears under the Then and And-statements. It allows you to perform mathematical operations on numerical data (such as price, quantity, or weight) within your product feed.

You can choose from the following operations:

* Multiply by.
* Divide by.
* Plus.
* Minus.
* Multiply by field.
* Divide by field.
* Plus field.
* Minus field.

{% hint style="info" %}
**Decimal values are supported for calculation.**
{% endhint %}

This rule is ideal for custom pricing, applying discounts, and unit conversions.

**Example:** Product pricing plays an important role in attracting buyers. You want to lower your prices on Google Shopping to offer special discounts for buyers purchasing through the platform. The following action can be set:

Take “Price” and “calculate” - take “Price” - “minus” - “2”.

This will allow LitCommerce to use your Main Store prices, minus 2, and display the corresponding values for each product accordingly.

For instance, after this rule is applied, “Bee Cupcake produced by Crème Florale Co.” shows a price of 11 in the feed instead of its original 13.
