The calculation is a ratio of current performance against potential performance, expressed as a percentage.
The Formula:
Demand-Side Strategies: Increase sales through price promotions, targeted marketing, or finding new markets to fill the output gap.
Supply-Side Strategies: Reduce the maximum capacity by selling off underused assets, closing unproductive branches, or reducing staff levels (downsizing).
Operational Flexibility: Use outsourcing to handle peak demand or redeployment to move staff from quiet areas of the business to busy ones.
| Feature | Under-utilisation | Over-utilisation |
|---|---|---|
| Unit Costs | High (Inefficient) | Low (Efficient) |
| Flexibility | High (Can take new orders) | Low (No room for error) |
| Staff Impact | Boredom / Redundancy fears | Stress / Burnout |
| Maintenance | Easy to schedule | Difficult (causes downtime) |
Check the Units: Always ensure that 'Actual Output' and 'Maximum Output' are measured in the same units (e.g., both in millions or both in units) before dividing.
The 100 Multiplier: A common mistake is forgetting to multiply the decimal result by 100 to provide the answer as a percentage.
Interpret, Don't Just Calculate: If asked for implications, connect the percentage to Average Fixed Costs. A lower percentage always implies higher unit costs.
Sanity Check: Capacity utilisation cannot realistically exceed 100% for long periods; if your calculation results in 150%, re-check which number is the 'Maximum'.
