The free CPM calculator

CPM stands for cost per mille — the cost per 1,000 impressions. It's the standard pricing unit in advertising and influencer marketing that lets you compare the efficiency of different campaigns and creators regardless of audience size.

CPM = (Total cost ÷ Total impressions) × 1,000. For example, a $2,000 campaign that generates 400,000 impressions has a CPM of $5.00. This calculator also works in reverse — enter cost and CPM to find impressions, or impressions and CPM to find cost.

Creator campaigns typically run $5–$25 CPM on Instagram and TikTok and $15–$50 on YouTube, with targeted or premium niches pushing toward $30–$75+. CPM in the low single digits is usually efficient, but weigh it against engagement and conversion — cheap impressions from bots are worthless.

CPM measures cost per 1,000 impressions (reach efficiency), CPE is cost per engagement (likes, comments, clicks), and CPA is cost per acquisition/sale. Track CPM for awareness campaigns, CPE for engagement goals, and CPA for performance and ROI.

High CPM usually means a small audience relative to cost, a premium niche, or low organic reach. It's normal for highly targeted campaigns. Check whether the impressions are from genuine, engaged followers — a high CPM with strong conversion can still be a win.
