Ask a company what an hour of downtime costs and most will not know. The reason is simple: the visible part — the IT effort to fix the problem — is small. The real cost sits elsewhere, spread across departments, and nobody adds it up.
The visible part is the smallest part
When a system fails, people wait. Quotations are not sent, orders are not entered, customers call and are put on hold. When it comes back, work has to be redone, data has to be checked, and someone has to explain to a customer why the promised quotation did not arrive.
A simple way to calculate it
You do not need a consultant to estimate it. Multiply the people affected by what an hour of their time costs, and add the business that does not happen in that hour:
Example values — put in your own. Not included: rework, penalties and the customers who do not come back.
Even with cautious numbers, a single bad morning often costs more than a year of proper monitoring and redundancy. That is the comparison that matters — not the price of a server.
Why it is rarely measured
Downtime that nobody measures does not exist in a budget. So the investment that would prevent it competes with projects that do have numbers — and loses. Measuring it once, honestly, changes that discussion.
The cheapest hour of downtime is the one that is noticed and fixed before anyone has to wait. That is what monitoring is for — Monitoring Is Not Watching: What Real System Monitoring Looks Like.
