Break-even ACoS, TACoS & contribution margin

Connect advertising metrics to your actual margin instead of optimizing ACoS in isolation.

When ACoS is optimized without a target value.

Many accounts lower ACoS without knowing the actual target value.

  • ACoS is lowered without knowing which value is profitable at all
  • TACoS is rarely calculated, even though it shows the bigger picture better
  • Contribution margin per product does not feed into ad management
  • Campaigns are scaled by gut feeling instead of by numbers
  • Reporting shows ad costs but no link to actual profit

How we connect advertising to margin.

01

Calculate break-even ACoS

Per product, based on the real margin.

02

Introduce TACoS

Make ad spend visible relative to total revenue.

03

Link contribution margin

Tie ad management directly to profitability.

04

Establish control logic

Clear rules for scaling, holding and reducing.

What is included.

Break-even ACoS calculation per product
TACoS tracking and interpretation
Linking ad data with contribution margins
Clear scaling rules per product phase
Dashboard/reporting template for ongoing control
Alignment with the profitability analysis

One number, two areas

Contribution margin is not looked at separately for Amazon and the shop but across channels, aligned with the profitability & contribution margin analysis from e-commerce consulting.

Result: Clear scaling rules per product, derived from the actual contribution margin rather than from ACoS alone.

Start transparently.

Break-even ACoS is the point at which advertising uses up the entire contribution margin. It is different for every product, so a flat target value for the whole account almost always misses reality.

Frequently asked questions.

What is the difference between ACoS and TACoS?

ACoS only relates to advertised revenue, TACoS to total revenue. TACoS shows the fuller picture.

How is break-even ACoS calculated?

From margin, fixed costs and target profit per product: individually, not as a flat figure.

Is the standard Amazon report enough for this?

No, it needs to be linked to your contribution margin calculation.

How often is the control logic adjusted?

When prices, costs or margins change, and at least quarterly.

Does this also work for new products without history?

Yes, with an estimated target ACoS that is calibrated after the first data comes in.
