FAQ
How is contribution margin different from gross margin?
Contribution margin includes additional variable costs like transaction fees and ad cost, not just product cost.
What if contribution profit is negative?
The offer loses money per order. Raise price, lower variable costs, or reduce acquisition cost before scaling.
Why is this metric useful for paid media?
It directly shows how much value remains from each order after acquisition and variable operating costs.
