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.
