What is Cost Per Acquisition?
CPA is the total cost to acquire one paying customer. It is the fundamental metric for performance marketing — you must know your CPA to know if campaigns are profitable.
Formula
Conversion Rate = Conversions / Clicks x 100
Max Profitable CPA = Revenue per Conversion x Gross Margin%
ROAS = Revenue / Spend
Examples
CPA: $50 | Max Profitable CPA: $82.50 | ROAS: 3x | Net Profit: $1,300 | CR: 1%
CPA: Rs 400 | Max Profitable CPA: Rs 320 | Slightly unprofitable — optimise
£5,000 spend, 80 conversions, £150 product revenue, 50% margin. CPA: £62.50 | ROAS: 2.4× | Max CPA at 50% margin: £75 | Net profit: £2,500
Why Use This?
If CPA < Max Profitable CPA, scale up. If CPA > threshold, pause and optimise first.
