Model and cost definitions

CM3 is net revenue less product, fulfillment, payment fees, gift cost, and ad spend. This view uses a 3% payment fee. The workbook adds returns, shipping collected, affiliate costs, and campaign costs.

Enter your gift value and internal gift cost separately. Gift value changes the modeled order response. Gift cost changes contribution. Optional order growth inputs replace the modeled response.

The chart holds the offer and CM3 goal constant. Each point pairs total ad spend with the highest blended CPA that reaches the goal. Lower CPA produces more contribution at that spend. The blue line shows the CPA needed. The shaded band shows modeled CPA. Hover or drag to explore. When the chart has focus, use the wheel or arrow keys.

The table compares offers at your baseline spend. Modeled CPA changes with offer value and total spend. Orders, net revenue, and contribution use the same response calculation. Amount-off response applies only to qualifying orders.
