How to use

Why use this tool

A per sale ceiling makes the pricing constraint visible before an advertising budget is committed.

Before relying on the result

Negative headroom means the chosen profit target is not met even before ads. This is a per order arithmetic ceiling, not a campaign performance forecast.

Tool limitations

Questions

What does negative headroom mean?

The chosen contribution target is already missed before advertising. A zero ad spend would not repair that baseline.
