How to Calculate CPA: Simple Formula and Steps
The core formula for CPA is simple yet powerful. To determine your Cost per Acquisition for any campaign, use the following structure:
Cost per Acquisition (CPA) = Total Ad Spend ($) / Total Conversions (Customers or Leads)
For example, if your team spent $1,200 across Google and Facebook Ads, and you acquired 40 paying customers, your CPA would be $1,200 / 40 = $30 per customer. Repeat this process for each campaign, channel, or marketing period to gain a clear picture of your acquisition efficiency.
Detailed CPA Calculation Examples
- Example 1: If an e-commerce campaign costs $3,500 and earns 100 new customers, the CPA = $3,500 / 100 = $35.
- Example 2: A software company spends $2,100 and gains 28 conversions. CPA = $2,100 / 28 = $75.
- Example 3: A freelance marketer runs Instagram ads worth $480 and secures 12 leads. CPA = $480 / 12 = $40.
- Example 4: A SaaS business spends $10,000 and enrolls 180 trial signups. CPA = $10,000 / 180 ≈ $55.56.
- Example 5: Nonprofit organization invests $900 in a campaign and mobilizes 45 new donors. CPA = $900 / 45 = $20.
