How to use a campaign loss cap
Limit the amount a test can lose while preserving useful evidence.
Define the cap in dollars
A campaign can tolerate losing $600 in contribution after ads. At $900 spend and $400 in settled pre-ad contribution, the measured loss is $500. Track media and contribution separately so an increase in reported revenue cannot hide the remaining risk.
Include outcomes that have not matured
If ads keep running while sales are pending, forecast plausible settlement and record the worst near-term exposure. A cap based on immediate sales alone can stop a healthy campaign early. A cap that assumes all pending leads will convert can miss a real loss.
Plan who acts and when
Pick review times and give someone authority to stop delivery. Record the minimum information required before restarting, such as repaired tracking or a new audience. A stop cap protects the test budget and does not resolve whether the campaign concept was sound.
