Features

Deal Type Revenue Breakdown

See revenue split across Open Auction, Private Marketplace (PM), Programmatic Guaranteed (PG), and Preferred Deals. Each deal type has its own eCPM and buyer fee rate, giving you a complete picture of your programmatic revenue mix.

Revenue Waterfall Visualization

Track every dollar from gross revenue to net publisher revenue. The visual waterfall shows exactly how much goes to AdX buyer fees (10-20%), GAM platform fees (10-20%), and how much you actually take home.

Header Bidding vs AdX Only Comparison

Quantify the revenue lift from header bidding. Compare your current revenue mix (with HB) against a hypothetical AdX-only scenario to see exactly how much additional revenue header bidding generates for your inventory.

CPM Floor Price Optimization

Model how changing your open auction floor CPM affects revenue at different fill rates. See the trade-off between higher floor prices (higher CPM, lower fill) and optimize for maximum net revenue.

Use Cases

Publisher Revenue Forecasting

Digital publishers using Google Ad Manager need accurate revenue projections. Enter your monthly impression volume and deal mix to forecast net revenue across all programmatic deal types.

Header Bidding Investment Decision

Deciding whether to invest in a header bidding wrapper (Prebid, Amazon TAM, etc.)? Use the HB vs AdX-only comparison to calculate the revenue lift and ROI of implementing header bidding on your site.

Ad Ops Team Performance Review

Ad operations teams can use this calculator to analyze deal type performance, identify underperforming deal types, and optimize the mix toward higher-CPM programmatic guaranteed and private marketplace deals.

Floor Price Strategy Optimization

Experiment with different floor CPMs and see the projected revenue impact at various fill rate scenarios. Find the sweet spot where higher CPMs offset lower fill rates for maximum net revenue.

Buyer Fee & Platform Fee Analysis

Understand the total cost of programmatic advertising - from AdX buyer fees (10-20%) to GAM platform fees. See exactly what percentage of your gross revenue goes to Google at each stage of the waterfall.

Pre-RFP Inventory Packaging

Sales and partnerships teams preparing for programmatic guaranteed or PMP deals can use real impression data and CPM projections to package inventory and set rate card prices for direct-sold programmatic.

About

What Is Google Ad Manager (GAM)?

Google Ad Manager (formerly DFP + AdX) is Google's enterprise ad serving and programmatic selling platform. It combines an ad server (GAM) with a real-time exchange (AdX) that connects publishers with advertisers through open auction, private marketplaces, and programmatic guaranteed deals. Publishers with over 5M monthly impressions typically use GAM to maximize yield.

How Do AdX Buyer Fees Work?

Google AdX charges buyers a fee on each transaction, which reduces the net amount paid to the publisher. Buyer fees vary by deal type: ~10% for Open Auction and Preferred Deals, ~12% for Private Marketplace, and ~15% for Programmatic Guaranteed. These fees are deducted before the publisher receives their net revenue - the calculator accounts for this automatically.

What Is Header Bidding and Why Does It Matter?

Header bidding (also called pre-bidding or advance bidding) is an advanced programmatic technique where publishers offer their inventory to multiple ad exchanges simultaneously before calling Google AdX. This creates competition that drives up CPMs - typically increasing revenue by 20-50% compared to AdX-only waterfall. The "Header Bidding Impact" section quantifies this lift for your specific numbers.

What Is a CPM Floor Price?

A CPM floor price is the minimum price a publisher is willing to accept for 1,000 ad impressions. Setting the right floor is a delicate balance: too high, and fill rate drops (fewer ads sold); too low, and you leave money on the table. The floor price optimizer helps you model different floor prices and their impact on total revenue.

FAQ

Gross revenue for each deal type = (Filled Impressions × Deal Type %) ÷ 1000 × eCPM. For example, if you have 500K impressions at 85% fill rate (425K filled) and 20% goes to Private Marketplace with a $3.00 eCPM: (425,000 × 20%) ÷ 1000 × $3.00 = $255.00 gross from PM deals.

AdX buyer fees vary by deal type: Open Auction and Preferred Deals charge ~10%, Private Marketplace (PMP) charges ~12%, and Programmatic Guaranteed (PG) charges ~15%. These fees are deducted from the gross revenue before the publisher receives their net. The total buyer fee across all deal types typically ranges from 8-12% of gross revenue.

Google Ad Manager charges a platform fee that typically ranges from 10-20% of gross revenue, depending on your contract size and volume. Larger publishers with higher impression volumes (500M+/month) can negotiate lower rates. The default in this calculator is 15%, which is common for mid-sized publishers.

Header bidding typically increases programmatic revenue by 20-50% compared to an AdX-only setup. The exact lift depends on your traffic quality, geography mix, ad format, and how many demand partners you have. The calculator models a 15% CPM lift with HB, which is conservative - many publishers see 30-50% higher CPMs with competitive header bidding.

Higher-quality publishers typically aim for: 30-40% Programmatic Guaranteed (highest CPMs, most predictable), 20-30% Private Marketplace (good CPMs with buyer targeting), 20-30% Open Auction (fill the rest), and 5-10% Preferred Deals. The optimal mix depends on your inventory quality, audience, and sales team capabilities.

Fill rate directly determines how many of your available impressions actually generate revenue. A 100% fill rate means every impression is sold; 80% means 20% of your inventory goes unfilled. Fill rate typically decreases as you raise floor CPMs - the floor optimizer helps you balance this trade-off for maximum net revenue.

This calculator is specifically designed for Google Ad Manager / AdX, which has different fee structures and deal types than AdSense. AdSense uses a simpler revenue share model (68% to publisher) without deal types, buyer fees, or header bidding. For AdSense projections, use the separate Google AdSense Revenue Calculator (Tool 93).

Effective eCPM (effective Cost Per Mille) is your net revenue per 1,000 impressions after all fees. It's the most important metric for comparing ad monetization performance. For example, if your gross eCPM is $3.00 but you lose 25% to buyer fees and platform fees, your effective eCPM is $2.25 - this is your true take-home rate per 1,000 impressions.
