Newsletter Ad CPM vs CPC Revenue Formula

CPM revenue is calculated per 1,000 opens (or subscribers). CPC revenue depends on open rate, click-through rate, and cost per click.

CPM Revenue per Ad = (Subscribers × Open Rate × CPM) / 1,000
CPC Revenue per Ad = Subscribers × Open Rate % × CTR % × CPC
Monthly CPM Revenue = CPM Revenue per Ad × Ads per Issue × Issues per Month
Monthly CPC Revenue = CPC Revenue per Ad × Ads per Issue × Issues per Month
Effective CPM = (CPC Revenue / (Subscribers × Open Rate / 1,000))

Industry benchmark open rates are 40–55% for niche newsletters. CTR benchmarks range 2–5% for general interest and up to 10%+ for highly engaged niche audiences.
