Most P&Ls have two margins. The decisions live in the ones between.
The margin cascade opens a standard profit and loss statement into the layers it usually hides: operational, commercial and company margin, not just gross and net. Each layer is multidimensional, and each one belongs to a team that can actually move it.
2 → 5
margin layers, from a gross-and-net P&L to a stepped cascade that points at decisions.
7
dimensions each layer can be cut by: transaction, product, hierarchy, customer, channel, plant, entity.
1
owner per layer, so every margin has a team accountable for the lever that moves it.
Collapsing everything into one line hides the levers.

- …everything else in one big line…
- Net profit✓
- Net sales
- Gross marginlayer 1 · product
- Operational marginlayer 2 · operations
- Commercial marginlayer 3 · commercial
- Company marginlayer 4 · finance
Each layer is a different question, asked of a different team.
Collapsing operations, commercial and structure into one line hides the levers. Separate them and each margin becomes a conversation with a clear owner, instead of an argument about whose costs they are.
Illustrative. Each landing is a margin a team can be held to. The gap between gross and company margin is where most of the management conversation actually belongs, and where a standard P&L stays silent.
Gross margin
Net sales minus the direct cost of the product itself. The classic line, and usually the only one that is clean to begin with.
Operational margin
Gross margin minus the cost of making and moving the order: production, warehousing, picking, packing and delivery.
Commercial margin
Operational margin minus the cost of winning and keeping the customer: sales effort, account management, customer service, returns.
Company margin
Commercial margin minus the indirect and structural cost of being a company at all: administration, finance, overhead.
The same layers, sliced by whatever dimension the question needs.
Because cost is attributed at the transaction, the cascade is not one report. It is the same margin logic re-cut along any axis you manage by, so operational margin by channel, commercial margin by product family, and company margin by customer all come from one consistent model, never reconciled by hand.
From "whose cost is this?" to "which layer do we move, and who moves it?"
A single net-profit number gives everyone something to point away from. A cascade gives each team a margin they own and a lever they control. That is the difference between a report people receive and a model people run.
Questions a CFO asks.
What is a margin cascade?
How is it different from a standard P&L?
What does multidimensional mean here?
The cascade builds directly on a cost-to-serve model. See also our pricing work.

The margin cascade follows one customer from invoice value all the way down to net profit, taking off each layer of cost in turn: product cost, then warehouse, delivery and account management drawn from the time equations. CaP's Foodservice D account shows how a respectable gross margin is steadily worn away by the cost to serve.
