Comparison of Under-Utilisation and Over-Utilisation
| Feature | Under-Utilisation (e.g., <70%) | Over-Utilisation (e.g., >95%) |
|---|---|---|
| Unit Fixed Costs | High, as fixed costs are spread over fewer units, reducing profit margins. | Low, as fixed costs are spread over a maximum number of units, increasing profit margins. |
| Staff Morale & Motivation | Can be low due to boredom, job insecurity, and a sense of failure. | Can be low due to stress, pressure, and burnout from excessive workload. |
| Flexibility & Responsiveness | High. The business can easily accept new orders and meet sudden increases in demand. | Very low. The business cannot accept new orders and may struggle to meet existing deadlines. |
| Impact on Quality | Can be high as there is more time for quality control. However, demotivated staff may become careless. | Likely to fall as workers are rushed, machinery is not maintained, and less time is spent on quality checks. |
| Brand Image | Can be perceived as unsuccessful or failing. Empty premises can look bad to customers. | Can be damaged by late deliveries and declining product quality. |

Calculating and Understanding Capacity Utilisation
Capacity utilisation is a crucial metric that measures the extent to which a firm's productive capacity is being used. It is expressed as a percentage of the maximum possible output (full capacity). The calculation is fundamental: (Current Output / Maximum Possible Output) x 100. For example, if a factory can produce 10,000 units per month but is currently producing 8,500, its capacity utilisation is 85%. This figure provides a snapshot of operational efficiency. A low percentage suggests wasted resources and high fixed costs per unit, while a very high percentage may indicate strain on resources and an inability to respond to new demand. Understanding this metric is the first step towards optimising production and improving profitability.
Capacity utilisation (%) = (Actual output ÷ Maximum output) × 100
Formula: (Current output level / Maximum output level) × 100.
Measures the proportion of potential output currently being achieved.
A key indicator of productive efficiency.
Maximum output is the total potential output if all resources are fully engaged.
Implications of Under- and Over-Utilisation
The level of capacity utilisation has significant implications for a business's costs, profitability, and brand image. Under-utilisation, where a firm operates well below its maximum capacity, leads to high unit fixed costs because overheads are spread across fewer units of output. This can make the business uncompetitive. It may also negatively affect staff morale due to fears of job insecurity. Conversely, over-utilisation, operating at or near 100% capacity for extended periods, can be equally damaging. It puts strain on machinery, leading to breakdowns, and on staff, causing stress and burnout. This pressure often results in a decline in quality and an inability to accept new orders, potentially damaging the firm's reputation.
Strategies to Improve Capacity Utilisation
Businesses can adopt several strategies to manage and improve their capacity utilisation. To address under-utilisation, a firm can focus on increasing demand through marketing campaigns, price reductions, or exploring new markets. Alternatively, it can reduce its maximum capacity through a process called rationalisation, which might involve selling assets or reducing staff numbers. To manage over-utilisation, short-term options include offering overtime to staff or subcontracting work to other firms. A long-term solution could be to invest in expanding capacity, but this is a significant decision that requires careful forecasting to ensure the higher demand is sustainable.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
A factory has a maximum output of 50,000 units per month and monthly fixed costs of $200,000. It is currently producing 35,000 units. Calculate the current capacity utilisation and the fixed cost per unit at both current and full capacity.
- 1
Utilisation = (35,000 ÷ 50,000) × 100 = 70%
A hotel has 80 rooms. On average, 55 rooms are occupied each night. The hotel is considering a marketing campaign costing $6,000 per month, which is forecast to increase average occupancy to 70 rooms per night. The average contribution per room-night is $80. Calculate the current and forecast capacity utilisation, and advise whether the campaign is financially viable.
- 1
Step 1: Calculate Current Capacity Utilisation Utilisation = (Current Occupancy ÷ Maximum Capacity) × 100 Utilisation = (55 ÷ 80) × 100 = 68.75%
