Formula

How we calculate

Formula reference
Net revenue = (Impressions * Fill * Viewability * (1 - Adblock) * (1 - IVT) / 1,000) * eCPM * Seasonality * Publisher share - Ad ops cost

This calculator treats CPM as a starting point. Realized revenue is adjusted by inventory quality, audience quality, and monetization economics.

CPM without quality filters usually overstates publisher take-home.

Use this model for planning ranges, then calibrate with your own observed reporting data.

Drivers

What moves this result

Viewability and fill rate can shift output more than small eCPM changes.
Adblock and invalid-traffic assumptions should be explicit in planning.
Rev-share and ad-ops overhead determine final net, not gross CPM alone.

FAQ

Quick answers

Why is this different from a basic CPM formula?

Basic CPM math ignores fill, viewability, adblock, invalid traffic, and rev-share. This model includes those levers so the net output is closer to reality.

Can this replace ad server reporting?

No. Use it for planning and scenario analysis, then calibrate against your observed reporting stack.
