CPM calculator
Calculate cost per thousand impressions and an estimated CPC at your entered CTR.
How the calculation works
CPM = ad spend ÷ impressions × 1,000. Estimated CPC = CPM ÷ (1,000 × CTR as a fraction).
What to include
CPM describes exposure cost. The estimated CPC assumes your entered click-through rate holds across those impressions. It does not predict the auction price or conversion quality. Compare the same impression definition and date range across reports.
Your inputs are calculated locally. We do not submit them or include them in analytics. These tools estimate advertising economics; they do not predict campaign performance.
