Standard

Enter any 2 of Cost, CPM, or Impressions and instantly solve for the third. The classic calculator, refined.

CPM = Cost / Impr × 1,000

CPA

Calculate Cost Per Acquisition from CPM, CTR, and conversion rate. Optionally project total conversions from impressions.

CPA = CPM / (1k × CTR × CR)

Break-Even

Find the maximum CPM you can afford before losing money. Add a target margin to bake in profit.

Max CPM = Value × CTR × CR × 1k
