Refresh — fatigue is building
Creative volume warning: at £12,000 per month you are running 3 active creatives, below the ~4 suggested for this spend. Too few creatives concentrates impressions and accelerates fatigue — size the gap with the creative volume calculator.
Enter the platform, how long the creative has been live, and the monthly spend behind it. Then add the signals that reveal fatigue: average frequency, the trend in CTR (a negative number means it is falling), the trend in CPA (a positive number means it is rising), and how many creatives are currently active. The calculator returns a 0–100 fatigue score, the likely driver, a recommended action and a suggested refresh window.
Creative fatigue happens when an audience has seen the same ad too often and performance begins to decline. In paid social, fatigue shows up as rising frequency, falling CTR, weaker conversion rate or increasing CPA — even when nothing about the campaign structure has changed. The full definition lives in the creative fatigue glossary entry.
No single metric proves fatigue, so the score combines several. Rising frequency means the same people are seeing the ad more often. A falling CTR shows the creative is losing attention. A rising CPA confirms the decline is hitting outcomes, not just engagement. Time live and a thin roster of active creatives both accelerate the effect. The calculator weights these into one risk score and names whichever factor is contributing most, so you know what to fix first.
On most paid social accounts, creative is the single biggest lever on performance — bigger than bids or audiences. Fatigue quietly raises CPA and caps how far a winning campaign can scale, so spotting it early protects efficiency. The fix is rarely a one-off: it is a steady supply of fresh assets, which is why this tool pairs naturally with the creative refresh cadence calculator and the creative volume calculator.
This calculator scores one set of creatives from the numbers you enter. ElenIQ’s Loki reads the trends automatically across your paid social and video campaigns, pinpoints which assets are fatiguing, and recommends whether to scale, refresh, pause or brief new creative — turning a manual check into an always-on signal.
Creative fatigue happens when an audience has seen the same ad too often and performance begins to decline. In paid social, fatigue can appear through rising frequency, falling CTR, weaker conversion rate or increasing CPA even when the campaign structure has not changed.
The score weighs the strongest signals of fatigue: ad frequency, the trend in click-through rate, the trend in CPA or ROAS, how long the creative has been live, and how concentrated spend is across too few active creatives. Each contributes to a 0–100 risk score, with the largest contributor flagged as the likely driver.
There is no universal threshold, but on most paid social platforms performance starts to soften once weekly frequency climbs above roughly 3–4 for prospecting audiences. Smaller audiences fatigue faster because frequency rises more quickly for the same spend.
It depends on severity. Early fatigue usually calls for refreshing the creative or briefing new variants while the winner still runs. Severe fatigue — high frequency with sharply falling CTR and rising CPA — is better handled by pausing and replacing, since extra spend mostly buys repetition.
ElenIQ’s Loki reads creative performance trends across your paid social and video campaigns, identifies which assets are fatiguing, and recommends whether to scale, refresh, pause or brief new creative — so you act before fatigue quietly inflates CPA.
Use Loki to read creative fatigue across every campaign automatically and act before tired assets inflate your CPA.
