What capacity utilisation is and how to calculate it

Capacity utilisation measures how much of a business's maximum possible output is actually being produced. It shows the efficiency of resource use. Capacity, also known as productive capacity, depends on factors such as the number of workers, their skills, available technology, production methods, and levels of investment.

Formula for capacity utilisation

$\text{Capacity utilisation (\%)}=\frac{\text{current output}}{\text{maximum possible output}}\times 100$

Where:

• Current output = The amount actually produced in a given period
• Maximum possible output = The highest amount that could be produced without additional fixed assets

High capacity utilisation is usually preferable to low levels.

Worked example - Calculating capacity utilisation

A factory's maximum possible output is 7,500 units per month, but it is currently producing 6,300 units per month. Calculate the capacity utilisation percentage.

Step 1: Identify the values

• Current output = 6,300 units
• Maximum possible output = 7,500 units

Step 2: Apply the formula

$\text{Capacity utilisation (\%)}=\frac{\mathrm{6,300}}{\mathrm{7,500}}\times 100$

Step 3: Complete the calculation

$\text{Capacity utilisation (\%)}=0.84\times 100=84\%$

The effects of over-utilisation and how to manage it

Over-utilisation happens when a business operates at 100% capacity, meaning it is producing at its absolute maximum.

Consequences of over-utilisation

• Balancing objectives - It becomes hard to focus on goals beyond just controlling costs.
• Quality issues - Maintaining high standards is difficult under constant pressure.
• Lost opportunities - The business may have to reject new customers or orders.
• Maintenance problems - There is no time for routine upkeep of equipment.
• Increased errors - Staff face higher stress, raising the chance of mistakes.
• Demand response - It is tough to handle peaks in seasonal demand or custom requests.
• Stock issues - Excess inventory might build up, locking away cash.

Ways to increase capacity and manage over-utilisation

• Extend operations - Run facilities for longer hours during the week.
• Add shifts - Introduce extra work periods, including weekends or holidays.
• Invest in equipment - Buy more machines to boost output.
• Expand workforce - Hire additional permanent staff.
• Use flexible staffing - Bring in temporary or part-time workers, or offer overtime.
• Boost productivity - Reorganise processes for better efficiency.
• Improve motivation - Enhance employee engagement to increase output.
• Outsource tasks - Pass work to external firms during peak times.

The effects of under-utilisation and how to manage it

Under-utilisation occurs when a business produces below its maximum capacity, leading to inefficiency and higher costs per unit.

Consequences of under-utilisation

• Higher unit costs - Fixed costs are spread over fewer items, pushing up the cost per unit.
• Price increases - Businesses may need to raise prices to cover costs.
• Reduced performance - This can lead to lower sales, profits, and market share.
• Brand damage - Customers might see the business as inefficient or struggling.
• Staff issues - Employees could become demotivated with less work, and there may be fewer chances for supervision or advancement.

Benefits of under-utilisation

• Order flexibility - It allows the business to take on new or unexpected orders.
• Maintenance opportunities - There is time to schedule equipment repairs and staff development.

Ways to address under-utilisation

Businesses can tackle under-utilisation by boosting demand or cutting capacity.

Increasing demand:

• Marketing adjustments - Change elements of the marketing mix, such as price or promotion, to attract more customers.
• Competitive strategies - Draw customers away from rivals.
• Fill spare capacity - Take on outsourced work from other firms.

Reducing capacity:

• Short-term options - End overtime or shorten working hours.
• Long-term options - Avoid replacing staff who leave, make redundancies, or sell off equipment to downsize.

Planning capacity for the long term

Businesses need to think ahead about how their capacity requirements will evolve. Effective long-term planning aligns capacity with expected demand.

Key considerations for long-term capacity planning

• Demand forecasting - Use market research to estimate future needs, though this involves some uncertainty.
• Short-term flexibility - Temporary adjustments help with seasonal products or one-off orders.
• Long-term benefits - Permanent changes, like investing in new facilities, can reduce unit costs if demand predictions prove correct.
• Risk management - Balancing capacity with anticipated demand avoids the pitfalls of over- or under-utilisation over time.
