Google Ads CPM Calculator
Estimate Google Ads cost from CPM and impressions—or estimate impressions from budget. Includes formulas, CPM range planning, copy-ready summary, and optional AI insights—free, no signup.
CPM here means Cost Per Mille (ad pricing), not Critical Path Method (CPM) or cost per mile.
Benchmarks are planning-only starting points. On Google Ads, CPM varies by network (Display vs YouTube), placements, geo, and auction competition. Use your own historical CPM when possible.
Benchmark CPM range: US$2.00 - US$5.00.
Enable range mode to see cost/impressions ranges from CPM min/max.
Cost result
US$4,000.00
Cost = (Impressions / 1,000) × CPM
Formula
Cost = (Impressions / 1,000) × CPM
Assumptions: CPM is priced per 1,000 impressions. This is a planning estimate; actual Google Ads CPM can vary by network, placements, targeting, viewability (CPM vs vCPM), and auction dynamics.
