What does an hour of IT downtime actually cost your business?
Most small businesses find out after the outage. Answer four questions and get a conservative, benchmark-backed estimate — per hour and per year.
By industry
Common questions
How is the downtime cost calculated?
The estimate combines two components: productivity loss (affected employees × fully loaded hourly wage × productivity impact) and revenue at risk (hourly revenue × an industry multiplier). The full formula, every constant, and all sources are published on the methodology page.
Is this calculator really free? What's the catch?
Yes — free, no email required, no account. Results appear instantly. We built it as a public tool; managed service providers can join a waitlist to offer a branded version on their own sites.
How accurate is the estimate?
It is a deliberately conservative screening estimate based on published benchmarks, not a substitute for a formal business impact analysis. Numbers are rounded down in spirit: we'd rather understate your exposure than inflate it.
Every constant in the model is documented on the methodology page.
