Downtime cost per hour, for maintenance managers
When someone asks “what does an hour of downtime cost?” they often want a single number. The useful answer is a short working: contribution margin on output you cannot recover, plus incremental labor, plus the fixed costs of the event, divided in a way you can show. Revenue is the usual overstatement. A blog’s “industry average” is not your plant.
The full formula, a checklist, and a synthetic example are on the downtime cost per hour page. Once you have a figure finance will at least discuss, you can turn hours into expected annual loss on the calculator. That is usually a more productive conversation than arguing about whether maintenance “costs too much.”
