How to calculate the cost of IT downtime?
The cost of IT downtime is often underestimated by businesses. It is not limited to the direct loss of revenue: it also includes the unproductivity of blocked employees, indirect costs related to reputation and stress, and sometimes contractual penalties towards your own clients.
Our downtime cost calculator uses a 3-step method to estimate your real financial risk:
- Hourly revenue loss: your annual revenue divided by 1,820 working hours, weighted by your IT dependency rate.
- Unproductivity cost: the fully loaded salary cost of your employees idle during the outage.
- Indirect costs: estimated at 20% of direct costs (reputation impact, loss of client trust, organisational stress).
According to Gartner, the average cost of one hour of IT downtime exceeds $300,000 for large enterprises. For an SMB, this amount is naturally lower but remains significant: between EUR 500 and EUR 5,000/hour depending on the business (roughly $550 to $5,500 USD).
The best protection against these costs is prevention: proactive 24/7 monitoring combined with a guaranteed response time allows you to detect and resolve incidents before they impact your business.
