How this tool works
Inputs, units and where to find them
| Input | Unit | Typical source |
|---|---|---|
| Downtime | hr | Duration of the stoppage |
| Lost contribution / operating hour | $/hr | Contribution lost per operating hour (sales value minus variable cost) |
| People affected | people | People unable to work productively |
| Loaded labour rate | $/hr | Loaded labour rate |
| Restart / recovery cost | $ | Scrap, cleaning and recovery cost to restart |
Method and formulas
- Lost contribution = hours × contribution per hour
- Idle labour = hours × people × rate
- Total = lost contribution + idle labour + restart
Limitations
- If output is recovered later, lost contribution is overstated
Typical uses
- Ranking maintenance improvements
- Justifying critical spares
Who it is for
- Maintenance and operations managers
What you get
- Total downtime cost and cost per hour
- Cost composition
Interpreting the result
- Use cost per downtime hour to rank preventive actions
