Frequently Asked Questions
Answers to common questions teams ask us
How do you calculate the cost of downtime?
We spread your annual revenue evenly across the year to get a revenue-per-minute figure, then multiply by the outage length and the share of revenue that depends on the affected system. It's a simple, defensible estimate — real incidents also carry support, reputation, and recovery costs.
What should I include as revenue?
Use the annual revenue that flows through the system you're monitoring — for a store, your annual online sales; for a SaaS product, annual recurring revenue. Then set the "share affected" to how much of that stops during an outage.
Does this include non-revenue costs?
No — this estimates direct revenue loss only. Engineering time, SLA credits, churn, and brand damage typically make the true cost higher, which is why catching outages early pays for itself.
