# Leveraging Margin Data

Nosto for Shopify now allows you leverage your cost-per-item field via Nosto's Intelligence Engine.

Nosto's [advanced dynamic filtering and inclusion and exclusion filters](https://help.nosto.com/en/articles/586449-recommendation-filters) can be be configured to use the margin data.

The advanced dynamic filtering allows you include and exclude products by leveraging your margin data. The margin is calculated using the formula (\[price - cost] / price) *100) and is shown on Shopify's product details page. For example, if your price is 50, and your cost is 30, then the margin (calculated as (\[50 - 30] / 50)* 100) is 40%. We recommend reading Shopify's [detailed product pricing guide](https://help.shopify.com/en/manual/products/understanding-products#pricing) to learn more.

## Setting it up

In order to set it up, you'll need to reinstall the Nosto app for Shopify. Reading the cost-per-item property requires some additional permissions and this can be done via a simple reinstall.

Once you've clicked on the Nosto app in your apps section, you'll be prompted with a permission dialog that resembles the following image.

Once you've reinstalled the app, we'll begin collecting the cost-per-item data organically. In order to expedite this process, simply initiate a one off reindex. <https://help.nosto.com/settings-and-troubleshooting-faq/tools-product-reindexupdate>
