Meta New Customer CPA measures the average cost to acquire one first-time buyer through Meta advertising.
Meta NC CPA = Meta Spend ÷ Meta New Customer Purchases
Example
Your DTC brand spent $8,000 on Meta ads in March and acquired 100 new customers.
How It Works
Meta calculates New Customer CPA by dividing ad spend by purchases from first-time buyers. This requires configuring the new customer signal through Meta’s Conversions API or Pixel. The metric isolates acquisition efficiency from repeat purchases, giving you a true cost of customer growth separate from retention-driven revenue.
