Impression Calculator from CPM
Estimate impressions from CPM and budget (or reverse to estimate budget). Includes formulas, CPM ranges, 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. Use your own historical CPM data when possible.
Enable range mode to see budget/impressions ranges from CPM min/max.
