Why These Metrics Matter

Every successful ecommerce business is built on understanding its numbers. These calculators help you measure advertising efficiency, profitability, and growth — the fundamentals of scaling a Shopify store.

How to Use These Metrics Together

Individual metrics tell part of the story. ROAS tells you how much revenue your ads generate, but it says nothing about whether that revenue is actually profitable. A store running at 4x ROAS looks healthy on paper — until you realize the product margins are only 20%, meaning most of that revenue goes straight back to suppliers. Pair ROAS with your profit margin to find your true break-even point and set realistic ad spend targets.

Conversion rate ties everything together. If your CPC is low but your conversion rate is poor, you're paying for traffic that doesn't buy. If your CPM is rising but your conversion rate is climbing faster, your campaigns may still be improving overall. The most useful analysis comes from looking at how these numbers move relative to each other — not in isolation.

Once you know your baseline metrics, the next step is understanding which channels and campaigns drive the best combination of cost and conversion. That's where attribution tracking comes in. To get started, read our full Shopify attribution tracking guide.
