Machine Downtime Cost Calculator – Unplanned Stop Financial Tracker
Stop the Profit Leak: Machine Downtime Cost Tracker
Machine downtime is more than just a stopped clock—it is a direct leak in your company’s profits. Whether it is a mechanical failure, power outage, or material shortage, every minute a machine stands idle, your "Cost of Quality" rises. This tool helps you quantify those losses in real currency, making it easier to justify maintenance investments.
Downtime is a major factor in reducing your Availability Score in OEE. By tracking the financial impact here, you can prioritize which machines need an improved Efficiency Strategy to protect your bottom line.
Financial Loss Formula
To find the total financial loss during a breakdown, use this calculation:
Total Cost = (Downtime Mins ÷ 60) × (Hourly Labor + Hourly Revenue)
- Labor Cost: Wages paid to operators while the machine is idle.
- Revenue Lost: The market value of products that were scheduled for production.
Frequently Asked Questions (FAQ)
What is the most common cause of downtime?
In 2026, research shows that most unplanned downtime is caused by a lack of preventive maintenance and operator error. Minor issues that are ignored often lead to major mechanical failures.
How does tracking downtime improve OEE?
Downtime directly impacts the "Availability" score in Overall Equipment Effectiveness. By reducing idle time, you immediately boost your OEE percentage and factory throughput.
Should I include electricity costs in this calculation?
Usually no, as machines consume less power when idle. However, you should include fixed factory overheads and potentially the waste generated during restart, which can be tracked using our Wastage & Scrap Calculator.
