CPM, CPC, CPA - Which Metric Matters?

CPM (Cost Per Mille, "mille" being Latin for thousand) is what you pay per 1,000 ad impressions. CPC (Cost Per Click) is what you pay per click on your ad. CPA (Cost Per Acquisition) is what you pay per actual conversion (signup, purchase, etc.). The relationships: CPC = CPM / (CTR × 10), and CPA = CPC / conversion_rate. CTR (click-through rate) is clicks/impressions.

CPM is the right metric for brand awareness campaigns where the goal is exposure. CPC is right for direct-response campaigns where you want clicks (driving traffic). CPA is right for performance campaigns where you want conversions (a metric that ties back to revenue). Most platforms now optimize automatically for the metric you select - choose the one closest to your business goal.

Industry benchmarks vary widely by vertical and platform. Finance and legal have the highest CPCs ($5-50+) because conversion value is high. E-commerce runs $1-3 CPC. B2B SaaS on LinkedIn can run $10-50 CPC. The 2026 averages above are aggregate; your numbers will land in a different spot based on audience targeting, creative quality, landing page, and competition.

Benchmarks are aggregate industry averages and vary substantially by vertical, geography, audience, and ad quality. Run controlled tests on small budgets before scaling spend.
