Net CPM After Revenue Share Calculator

Reveal how much CPM you keep after a platform takes its cut. Enter the gross CPM and revenue-share percentage; optionally add fill rate to see realized earnings per thousand pageviews for quick channel comparisons.

Advertiser or network CPM before revenue share.
Percent the platform keeps (e.g., 32% for some ad servers).
Defaults to 100%. Lower fill reduces realized revenue per 1,000 pageviews.

Illustrative only. Confirm contracted revenue shares, pass-through fees, and billable impression counts with your ad platform.

Examples

  • $18 CPM, 32% share, 92% fill ⇒ Net CPM after 32.00% share: $12.24 • Realized revenue per 1,000 pageviews at 92.00% fill: $11.26.
  • $24 CPM, 15% share, fill blank (defaults 100%) ⇒ Net CPM after 15.00% share: $20.40 • Realized revenue per 1,000 pageviews at 100.00% fill: $20.40.

FAQ

Does this include ad serving fees?

No. Subtract ad serving or payment processing costs separately to get to net revenue after all expenses.

How should I handle multiple revenue shares?

Apply the calculation stepwise or multiply gross CPM by the combined keep rate (e.g., 0.68 × 0.95) before comparing channels.

Can I use it for CPC campaigns?

Convert your CPC and expected click-through rate into an effective CPM first, then run this calculator to see the net value after revenue share.

Additional Information

  • Revenue share is applied directly to the gross CPM; fill rate scales realized earnings to reflect unsold impressions.
  • Results are rounded to two decimals and shown as dollars per thousand pageviews for easy RPM comparisons.
  • Use net CPM to evaluate direct deals versus network demand or to model header bidding floors.
