How much can a blog earn from ads? This calculator estimates it two ways: the classic CTR × CPC model, or directly from page RPM if you know it — returning monthly and yearly projections plus your effective RPM.
Using CTR × CPC
Niche RPMs range $2–$40+; finance & B2B highest
Reality check built in: niche RPMs range from $2–$5 (entertainment) through $10–$25 (marketing, tech) to $30–$40+ (finance, insurance, B2B). Traffic source matters too — US/UK organic traffic monetizes several times higher than social spikes.
EPC + conversion rate to compare offers fairly.
CPM, per-impression cost, impressions per $100.
Work out whether your link building spend actually pays back.
