Understanding the CM1–CM4 profit waterfall

What each Contribution Margin level means and how to use them to make decisions.

Contribution Margin (CM) is how Setpilot represents profit at different levels of cost attribution. Instead of collapsing everything into one "profit" number, Setpilot shows you four levels (CM1 to CM4) so you can see exactly where money is being made or lost.

The four levels

Level

Formula

What it tells you

CM1 — Gross Profit

Net Revenue − Product Costs

How much margin your products carry before any operational costs. Your pricing vs COGS story.

CM2 — Order Profit

CM1 − Order Processing

Margin after the cost of fulfilling an order (shipping, payment fees). Your operations story.

CM3 — Contribution Margin

CM2 − Marketing

Margin after acquisition cost. The truest number for measuring per-order profitability at scale.

CM4 — Net Profit

CM3 − Other Costs

Bottom-line profit after fixed overheads. What you actually take home.

When to look at each level

  • CM1 — when evaluating pricing, cost negotiations with suppliers, or discount depth. If CM1 is thin, no amount of marketing optimisation saves you.

  • CM2 — when evaluating shipping policies (free shipping thresholds, carrier rates) and payment method mix.

  • CM3 — when evaluating ad channels and acquisition economics. CM3 per customer is the truest LTV input.

  • CM4 — when evaluating the business as a whole, for monthly or quarterly reviews.​

A worked example

Imagine an order worth $100 in Net Revenue:

Step

Amount

Running total

Net Revenue

$100.00

$100.00

− Product Costs (COGS)

−$35.00

CM1: $65.00

− Shipping

−$8.00

− Payment fees (2.9% + $0.30)

−$3.20

CM2: $53.80

− Marketing (allocated)

−$22.00

CM3: $31.80

− Other (apps, salaries, etc.)

−$9.50

CM4: $22.30

That is a 22.3% net profit margin on the order — healthy for a typical DTC store.

Common mistakes

  • Optimising only for revenue. A revenue-positive campaign can be CM3-negative if the acquisition cost is too high.

  • Ignoring CM1. If your product margin is structurally low, scaling marketing will only scale your losses.

  • Confusing ROAS with profit. ROAS is Net Revenue ÷ Ad Spend. It tells you nothing about whether an order was profitable.​

Where CM is shown

CM1 through CM4 appear on the dashboard KPI tiles, in the P&L waterfall chart, on individual order rows in the Orders page, and in the Products page for per-SKU margin analysis.
