CPM (cost per mille) is the price you pay for 1,000 ad impressions. It is the standard way to compare media costs across Meta, Google, programmatic, and publisher inventory.
Enter any two values and calculate the third — find CPM from spend and delivery, estimate budget from a target CPM, or reverse-engineer how many impressions a budget can buy.
CPM = (Ad spend ÷ Impressions) × 1,000. Cost and impressions modes rearrange the same equation so you can plan campaigns quickly.

A CPM calculator converts between ad spend, impressions, and cost per thousand impressions so you can price media, check platform reports, or forecast delivery.
Divide total ad cost by impressions, then multiply by 1,000: CPM = (Cost ÷ Impressions) × 1,000. Example: $500 spend on 100,000 impressions is a $5.00 CPM.
It varies by channel, geo, placement, and audience. Social and display often land in single to low double digits in many markets, while niche or competitive verticals run higher. Compare against your own historical benchmarks.
