About this calculator
Every ad has a finite useful life. The same audience seeing the same creative repeatedly stops responding — CTR drops, CPMs rise, conversions decline. The challenge is knowing when to refresh: too early, you abandon ads still in their sweet spot; too late, you waste spend on dead creative.
This calculator estimates fatigue timeline based on three inputs: audience size, daily spend (which determines how fast you saturate), and ad format (which has different inherent fatigue rates). Format matters significantly — UGC creator content fatigues 2× slower than polished brand video because it doesn\'t feel like an ad to begin with.
The math: daily impressions = (daily spend / CPM) × 1000. Cumulative impressions / audience size = average frequency. Once average frequency hits 5-7 (saturation point), fatigue accelerates rapidly. The calculator returns the day count to reach that saturation point at your current spend pace.
Use this as a planning tool: when you launch a creative, calculate its expected lifespan and pre-schedule the next replacement creative\'s production timeline. Pair with the Creative Fatigue Detector (real-time CTR monitoring) and the Frequency Cap Calculator for full audience-saturation planning.
Frequently asked questions
How quickly do ads fatigue?
Static images: 14-21 days at typical frequency. Video ads: 21-35 days (more variation in viewing experience). UGC creator content: 30-45 days (feels less ad-like). Carousels: 14-28 days. Reels/Stories: 7-14 days (faster fatigue from format placement).
What signals fatigue?
CTR drops 30%+ from peak. Frequency exceeds 5-7 weekly per user. CPM rises 15%+ even though audience hasn't changed. Comments/engagement turn negative. Best leading indicator: weekly CTR trend — once it bends down, the ad is past peak.
Should I refresh ads or audiences?
Both, in this order. First, kill fatigued ads and replace with fresh creative (cheaper than expanding audiences). Second, expand audiences if creative refresh doesn't restore performance. Third, consider whether the underlying offer/messaging is the problem.
How many creatives should I have on rotation?
For typical DTC: 6-12 active creatives at any time, refresh 2-3 per week. Prevents single-creative fatigue from dragging down account performance. Less than 4 creatives concentrates risk; more than 20 dilutes spend across underperforming variants.
Does Advantage+ Campaign Budget change fatigue?
Yes — Advantage+ rotates through your creative pool automatically, extending the lifespan of any single ad by 30-50%. Trade-off: less control over which creatives get spend. Best practice: stage 12+ creatives in an Advantage+ campaign rather than running them in separate ABO ad sets.
