Downtime Cost Calculator — Vietnam
Most plants know their downtime in hours. Few know it in đồng. Enter one line's monthly downtime and its cost drivers, and see the annual figure — split into margin that was never earned and overhead that kept running anyway.
Calculator
Tell us about the line:
Breakdowns and unplanned stops on this line, in hours.
Selling price minus material and other variable cost.
Labour plus fixed costs — power, rent, supervision — still running while the line is stopped, per hour.
Well-run plants hold unplanned downtime under 5% of planned time — about 20 hours a month on a two-shift line.
