Overview

New Customer Cost Per Acquisition (NCPA, New Customer CPA) measures the cost to acquire a new customer based on blended ad spend.

📘

NCPA = Blended Ad Spend ÷ New Customer Orders

The calculation is based on data in the Blended Stats table.

Detailed Breakdown

The formula above is derived from the following components:

• Blended Ad Spend = spend + custom_ad_spend, where

  • spend = SUM(spend) --> Ads table
  • custom_ad_spend = SUM(IF(is_ad_spend, amount, 0)) --> Custom Spend table

• New Customer Orders = SUM(new_customer_orders) --> Orders table

Insights and Actions

New Customer Cost Per Acquisition (NCPA, New Customer CPA) reveals how much it costs to acquire a new customer, helping assess the efficiency of your ad spend in driving first-time buyers.

• Monitor Acquisition Efficiency: Use NCPA to evaluate how effectively your ad spend translates into new customers. Rising NCPA may signal inefficiencies in your campaigns.
• Optimize Targeting Strategies: High NCPA might indicate that your targeting is too broad. Refine your audience to attract high-conversion, cost-effective segments.
• Compare with Lifetime Value (LTV): Pair NCPA with customer LTV to ensure the cost of acquiring new customers is justified by their long-term revenue potential.
