How to Create and Share NC Purchase Custom Conversion in Facebook (Meta)

What You'll Achieve

After completing this setup, you'll see New Customer metrics such as NC-ROAS (New Customer Return on Ad Spend), Cost per New Customer Purchase, and Total New Customer Conversions directly in your Facebook (Meta) Ads Manager.


Part 1: Add NC Purchase Metrics to Columns

Step 1: Open Column Customization

Step 2: Add NC Purchase Metrics

  • Under Custom Conversions, find your NC Purchase (or NewCustomerPurchase)

  • Select both:

    • Total - Shows total new customer conversions

    • Cost - Shows cost per new customer purchase


Part 2: Set up NC-ROAS Custom Metric

Step 3: Create NC-ROAS Metric

  • To add NC-ROAS, we need to create a custom metric.

  • In the Customize Columns window, click on Create custom metric.

Step 4: Configure NC-ROAS Formula

  • Set up your metric:

    • Name: NC-ROAS

    • Formula: NC Purchase Conversion Value ÷ Amount spent

    • Click Create metric

⚠️Important: Check "Everyone with access to this Business" if you want to share the metric with your team.

Step 5: Add NC-ROAS to Columns

  • Include NC-ROAS in your Customize columns if you want to display it there

  • Click Apply to save all column changes

Success🎉

Your Ads Manager now displays:

  • NC Purchase (Total) - Number of new customers acquired

  • NC Purchase (Cost) - Cost per new customer

  • NC-ROAS - Return on ad spend from new customers

⚠️Important: Initially, no NC Purchase data will appear in Ads Manager because Meta does not support attributing custom conversions from the past. Data only populates for conversions occurring AFTER setup.
