Calculate cost per 1,000 impressions (CPM) and cost per click (CPC) for any ad campaign.
CPM (cost per mille) measures ad cost per 1,000 impressions, while CPC (cost per click) measures cost per individual click - two of the most fundamental metrics in digital advertising.
CPM = (Total Spend ÷ Impressions) × 1,000 | CPC = Total Spend ÷ Clicks
$500 spent over 250,000 impressions and 3,200 clicks gives a CPM of $2.00, a CPC of about $0.156, and a CTR of 1.28%.
CPM is cost per 1,000 impressions (views); CPC is cost per click — CPM measures cost of exposure while CPC measures cost of actual clicks.
CPM = (total ad spend divided by total impressions) x 1,000.
CPC = total ad spend divided by total clicks.
