Ad to Net Margin Calculator

Contribution before ads can still look comfortable while acquisition quietly eats the order alive. Use this calculator to bridge the gap between pre-ad contribution and true net margin once traffic spend is attached to the order.

See what survives before and after ad spend
Measure how much contribution is consumed by acquisition
Connect order economics to net margin directly

Translate ad spend into net margin

Enter revenue, direct cost, fulfilment, fee rate, other variable drag, and ad cost. The result shows how contribution changes once acquisition is pulled onto the same order instead of kept in a separate dashboard.

Order revenue Gross order revenue before ad spend. Product cost Direct item or sourcing cost. Fulfilment cost Pick-pack, shipping, or delivery burden. Fee rate % Marketplace or payment drag on revenue. Other variable cost Packaging, inserts, or similar order-level drag. Ad cost CAC or attributed paid media cost for the order.

Three acquisition-pressure scenarios.

Formula

What the ad-to-net bridge shows

Net after ads = Order revenue - Product cost - Fulfilment - Fees - Other variable cost - Ad cost

This is a decision model for people who already know gross revenue is not the answer. It keeps the order intact while moving one step lower, from contribution before ads to the net that actually survives acquisition pressure.

Where acquisition gets underpriced

Teams stop at contribution before ads and treat paid traffic as a separate story.
Good ROAS can still leave weak net margin if the order is soft underneath.
Ad cost looks acceptable until it is expressed as a share of contribution.

Useful next step

Once the ad-to-net bridge is clear, compare it against breakeven ROAS and payout margin so the order has one coherent acquisition threshold instead of three dashboards.
