Downtime Cost Calculator

What Does Your Downtime Actually Cost?

Enter your own numbers below — every one is editable, nothing is prefilled with an assumption about your business. The formula for each line is shown next to it, and revenue is kept separate from contribution margin so nothing gets counted twice.

🛈 Every number on this page comes from the assumptions you enter, shown as a formula, not a guaranteed outcome. Change any assumption and the result updates — nothing here is fixed or hidden.

Shown for scale only. Revenue is not profit, and adding it to contribution margin would count the same lost output twice — the total below uses contribution margin instead.
