Calculate CPM (Cost Per Mille / per thousand impressions), total campaign cost, or total impressions for digital advertising.

Formula

CPM = (Cost ÷ Impressions) × 1,000
  • CPM stands for Cost Per Mille (thousand) — standard digital ad pricing.
  • Total Cost = CPM × Impressions ÷ 1,000.
  • Total Impressions = Budget × 1,000 ÷ CPM.

Calculate CPM for $1,000 / 100,000 impressions

Inputs
  • Calculate: cpm
  • Total Campaign Cost ($): 1000 $
  • Total Impressions: 100000
  • CPM ($): 10 $

CPM = ($1,000 ÷ 100,000) × 1,000 = $10 CPM.
