Creative Fatigue Detector

Creative fatigue is the silent budget killer in paid media. It happens when your target audience sees the same ad too many times, causing engagement to decline and costs to rise. The symptoms are predictable: CTR drops week over week, CPMs increase as the platform struggles to find engaged users, and frequency climbs past the point of diminishing returns.

Most media buyers detect fatigue by manually scanning dashboards and noticing when things feel off. By then, the damage is already done — you have been overpaying for underperforming impressions for days or weeks. This calculator automates the diagnosis by analyzing three consecutive weeks of CTR and CPM data alongside your current frequency metric.

The fatigue score combines three signals: the rate of CTR decline (weighted 1.5x because it is the earliest indicator), the rate of CPM inflation (weighted 1.2x as a cost signal), and a frequency penalty that kicks in above 3x. A score above 50 suggests significant fatigue. Above 70 means you should be refreshing creatives immediately. Below 30 means your ads are still performing within normal variance.

The typical creative lifecycle on Meta runs 2 to 4 weeks for most DTC brands before fatigue sets in. High-spend accounts burn through creatives faster. Best practice is to always have 3 to 5 new creative concepts in production so you can rotate fresh assets before fatigue tanks your performance. Use this tool weekly as part of your ad account review cadence.
