Gross to Net Merchant Margin Guide
Gross revenue is where the story starts, not where the decision should end. Merchant margin only becomes trustworthy once the order has been stripped of channel take, fulfilment burden, offer drag, return pressure, landed cost, and acquisition.
Step 01
Start from gross revenue, then treat it with suspicion
Gross revenue is useful only because it tells you the size of the order before the real business starts taking its share. If the team stops here, almost every next discussion becomes vulnerable to false confidence.

Step 02
Strip channel take and payment drag first
Marketplace fees, payment processors, store tooling, and blended checkout drag are the first cuts that turn gross into something more believable. This is where many orders already look softer than the dashboard suggested.
Payout after fees = Gross revenue - Channel fees - Processor drag - Fixed order fees
If the payout is still unclear at this stage, keep working in fee and payout tools before moving on. There is no point calculating ROAS or repeat contribution on a payout number that is still guessed.
Step 03
Pull in fulfilment, landed cost, returns, and offer drag
This is the layer where merchant margin gets separated from vanity profit. Product cost, landed cost, 3PL, shipping, return reserve, and promotional discount all belong in the same picture if the order is going to be trusted.
Common missing layers
- Landed cost hidden outside the order
- Fulfilment and packaging drag
- Discount and return pressure from the offer itself

Step 04
Only then move into net margin after acquisition
The order is not really net until traffic cost is attached to it. Break-even ROAS and ad-to-net margin are the final pressure tests, not the opening move.
Net merchant margin = Contribution after fees and ops - Ad cost
Once the order has survived every layer beneath gross revenue, the remaining net is the number that deserves strategic attention. That is the number you can scale with less self-deception.

Good habit
Rebuild merchant margin any time channel mix, fulfilment, offer structure, or CAC changes. Gross revenue is stable enough to remember; merchant margin rarely is.
FAQ
Gross to net merchant margin questions
What is the difference between gross revenue and merchant margin?
Gross revenue is the topline order value before business costs take their share. Merchant margin is what remains after fees, fulfilment, landed cost, offer drag, returns, and eventually ad cost are stripped out.
Why strip fee drag before ad cost?
Channel fees and operational drag belong to the order before acquisition is considered. Cleaning that stack first gives a more honest base for break-even ROAS or net margin decisions.
Which calculators usually pair best with this guide?
The most useful next tools are payout margin, offer margin waterfall, ad-to-net margin, break-even ROAS, and landed cost calculators because they cover the main layers between gross and net.
