Example

Your Shopify store generates $2,000 CM4 from new customers and spends $15,000 on ads.

Component	Value	Calculation
New Customer CM4	$2,000	First-order operating profit
Ad Spend	$15,000	Marketing cost
New Customer CM4 ROAS	0.13	$2,000 ÷ $15,000

How It Works

New Customer CM4 ROAS is typically low or negative because first orders must cover acquisition costs plus fixed overhead. This is the most stringent profitability test for customer acquisition.

Interpretation

Scenario	Meaning
CM4 ROAS > 0	First orders profitable after all costs
CM4 ROAS = 0	First orders break even fully loaded
CM4 ROAS < 0	First orders lose money; profitability requires LTV

Most brands have negative first-order CM4 ROAS—lifetime value makes acquisition profitable.

Metric	Relationship
New Customer CM4	Numerator (operating profit)
CM4 ROAS	Overall CM4 ROAS
Returning Customer CM4 ROAS	Repeat order CM4 ROAS
