About this tool
Alert Fatigue Calculator
The Alert Fatigue Calculator quantifies on-call alert burden, signal-to-noise ratio, and weekly hours lost to non-actionable alerts.
• Build a data-driven case for alert reduction with engineering leadership
• Identify whether noise or volume is the primary fatigue driver for your on-call team
• Calculate on-call engineer hours lost to non-actionable alerts per week
• Benchmark your alert signal-to-noise ratio against industry targets

FAQ
What does this tool tell you?
The Alert Fatigue Calculator quantifies on-call alert burden, signal-to-noise ratio, and weekly hours lost to non-actionable alerts.
What affects the result most?
Alert fatigue score: alerts_per_week / engineer_count — >10/week/engineer is high fatigue territory. Signal-to-noise ratio: actionable_alerts / total_alerts — below 50% indicates significant noise. MTTA (Mean Time To Acknowledge): high fatigue correlates with MTTA > 30 minutes.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
