👁️ CPM Calculator

CPM (Cost Per Mille, from Latin "mille" = thousand) is the cost an advertiser pays for 1,000 ad impressions. CPM = (Total Spend ÷ Total Impressions) × 1,000. It's the primary pricing model for display, video, and programmatic advertising where exposure (awareness) rather than direct clicks is the goal.

Approximate 2024 benchmarks: Google Display Network $2–$4, YouTube $9–$15, Facebook/Instagram $8–$14, Twitter/X $6–$9, LinkedIn $30–$60, TikTok $5–$10, Programmatic/RTB $2–$8. LinkedIn has the highest CPMs due to professional targeting precision. Rates vary widely by audience, vertical, ad format, and campaign timing.

Use CPM for brand awareness campaigns where reach and frequency matter — you want maximum eyeballs. Use CPC (pay-per-click) for direct response campaigns where you need measurable actions (clicks, sign-ups, purchases). CPM is better for top-of-funnel; CPC for bottom-of-funnel. Many platforms let you switch or use tCPM (target CPM) to optimize for both.

CPC = CPM ÷ (CTR × 10). Example: CPM = $5, CTR = 1% → CPC = $5 ÷ (1 × 10) = $0.50. If your CTR is 0.1%, CPC = $5 ÷ (0.1 × 10) = $5 — same effective cost whether you pay CPM or CPC with that CTR. Knowing any two of CPM, CPC, CTR lets you calculate the third.

eCPM = (Total Revenue ÷ Total Impressions) × 1,000. Publishers use eCPM to compare revenue across different ad types. Advertisers use it to compare campaign efficiency. eCPM = CPC × CTR × 1,000 = CPA × CVR × CTR × 1,000. Improving any of CTR, CVR, or CPA improves your eCPM.
