Capacity Utilisation in a Nutshell
Capacity utilisation is the proportion of a business’s maximum possible output that it actually uses, expressed as a percentage. High utilisation spreads fixed costs and lifts profit, but at 100% there is no slack for maintenance, surges in demand or staff absence. Most businesses aim for around 85% to 90%.
Capacity Utilisation Definition
Capacity is the maximum output a business can produce with its current resources. Resources mean staff, machinery, buildings and equipment. Capacity utilisation is the proportion of that maximum which the business actually uses. Think of a Premier Inn with 100 rooms. If 80 rooms are booked tonight, the hotel is using 80% of its capacity. The other 20 rooms still need cleaning, heating and lighting, but they earn no revenue.
Why does a budget airline cram every seat full? Why do cinemas sell cheap tickets on a Tuesday afternoon? The answer is the same: an empty seat earns nothing, but it still costs money. That one idea sits behind a topic that examiners love to test on AQA, Edexcel and OCR papers.
Capacity utilisation looks simple. It is one formula and one percentage. Yet students lose marks on it every year. Some forget to multiply by 100. Others write “high capacity is good” and stop there, with no chain of reasoning and no judgement. This note fixes both problems.
Studying and Revising?
Most students revise by re-reading notes or highlighting textbooks. That approach builds familiarity with content, but it does not show you whether your exam answers would earn marks. The AI Business Tutor marks your practice answers by assessment objective, shows you exactly where marks were gained or lost, and lets you rewrite and resubmit until your score improves.

Capacity Utilisation Characteristics/Features
- It is a percentage: It is always expressed out of 100, which makes it easy to compare firms of different sizes.
- It is a measure of efficiency: It shows how well a firm uses its fixed resources. A low figure suggests resources are going to waste.
- It is short term: Capacity only changes when the firm invests or cuts resources, so in the short run utilisation changes with output.
- It links to fixed costs: Fixed costs stay the same whatever the output level. Higher utilisation therefore spreads them across more units.
- It changes with demand: Seasonal businesses swing between high and low utilisation across the year.
- Spare capacity has a use: A small gap below 100% gives time for maintenance, holidays and unexpected orders.
That last point matters for AO2. Alton Towers is packed in August and quiet in November. A Greggs bakery runs its ovens hard at breakfast and lunch. Always ask: what does demand look like for this business?
Examples of Capacity Utilisation
Ryanair is a well-known example of a business that depends on high utilisation. Its aircraft lease costs the same whether the plane is full or half empty, so every extra passenger adds revenue at almost no extra cost. This allows low fares, which in turn helps to keep the planes full.
Cinemas such as Odeon show the opposite problem. A screening on a Tuesday afternoon may fill only a small fraction of the seats. To lift utilisation, cinemas run cheap-ticket days and student discounts, so the seats earn something rather than nothing.
An NHS hospital in winter shows the risk of the other extreme. Beds are full, so a new emergency means patients wait in corridors or ambulances. Most businesses aim for around 85% to 90% because this captures most of the cost benefits while leaving a buffer. These examples show that the right target depends on the cost of being full compared with the cost of being empty.
Advantages & Disadvantages of Capacity Utilisation
Advantages
Lower Average Costs
Fixed costs are spread over more units. Ryanair’s aircraft lease costs the same whether the plane is full or half empty, so more passengers means each seat carries less of that cost. The positive effect is lower unit costs and higher profit margins.
Higher Profit
Each extra unit sold contributes towards fixed costs. Once those are covered, extra contribution becomes profit. A full Odeon screen generates far more profit than a half-empty one, yet the film rental cost barely changes. The positive effect is a rapid rise in profit for each extra customer.
Room to Cut Prices
Lower unit costs give the business pricing power. It can undercut rivals and still make a profit, which is useful in a price-sensitive market. The positive effect is a larger market share in competitive markets.
Stronger Staff Morale
Busy workers often feel secure. Their jobs look safe because the business is clearly in demand. The positive effect is better morale, which can lift productivity and reduce staff turnover, cutting recruitment costs.
A Positive Image
A full restaurant signals quality. Customers see queues and assume the product is worth it. The positive effect is that demand can grow further without extra marketing spend.
Better Use of Investment
Shareholders want returns on the assets they fund. Machinery that runs constantly pays back its cost faster. The positive effect is an improved return on capital, which makes it easier to raise future finance.
Disadvantages
Staff Stress and Burnout
Workers face long shifts and constant pressure. Absence rises, and the business then pays agency staff or overtime to cover. The negative effect is higher costs and lower profit, as well as more mistakes from tired employees.
No Time for Maintenance
Machines must keep running, so servicing gets delayed. Small faults grow unnoticed. The negative effect is that breakdowns become more likely and more expensive, halting output completely.
Falling Quality
Rushed work leads to mistakes. Faulty products lead to returns and complaints. The negative effect is damage to the brand image, which can reduce demand.
Turning Customers Away
A firm with no spare capacity cannot accept new orders. Customers go to competitors instead, and some may never come back. The negative effect is lost long-term revenue.
Overtime Costs
Hitting targets often means paying staff extra. Overtime is usually paid at a higher rate. The negative effect is that unit costs rise, which wipes out some of the cost advantage of high utilisation.
Inflexibility
A sudden surge in demand cannot be met. When the PS5 launched, retailers simply could not get enough stock, and frustrated buyers looked elsewhere or turned to resellers. The negative effect is missed sales and weaker customer loyalty.
How to Calculate Capacity Utilisation
The formula is:
Capacity utilisation = (actual output ÷ maximum possible output) × 100
Break it into three steps. First, find actual output: what the business really produced or sold. Second, divide by maximum output, which gives a decimal such as 0.8. Third, multiply by 100 to turn the decimal into a percentage. Why this order? Dividing compares the part to the whole, and multiplying by 100 makes the answer easy to compare with other firms.
Worked example: a factory can make 5,000 bikes a month. It makes 3,500. So 3,500 ÷ 5,000 = 0.7. Then 0.7 × 100 = 70%. Always show your working, because if your final answer is wrong, the method can still earn a mark.
Common Mistakes
Forgetting to multiply by 100, and putting maximum output on top. If your answer is above 100%, you have flipped the numbers.
Memory Trick
“What you DID over what you COULD.” Did on top, could underneath.
Evaluating the Usefulness of Capacity Utilisation
A business with low utilisation has two broad choices: raise output or cut capacity. Raising output means boosting demand through off-peak pricing, extra marketing, new products or markets, or subcontracting in. Cutting capacity means selling machinery, closing a site, cutting shifts or making staff redundant. Which strategy is best depends on several factors.
Is the Fall in Demand Temporary or Permanent?
A seasonal dip suggests boosting demand, because the spare capacity will be needed again. A long-term decline suggests cutting capacity, because the lost demand is not coming back. Car makers have closed plants in Europe when demand weakened for good.
The Competitive Environment
What is the competition doing? Price cuts to fill spare capacity may spark a price war in a crowded market, leaving everyone with lower margins. In a market with few rivals, a price promotion is less risky.
The Business’s Objectives
A firm chasing growth will keep its capacity and try to fill it. One focused on survival will cut it to reduce fixed costs. A firm that wants a premium image may accept lower utilisation rather than discounting.
What the Business Can Afford
Marketing costs money. Redundancies also cost money upfront. A cash-rich business can pick the strategy that is best long term, while a stretched business may have to choose the cheaper option. Strong answers pick one strategy, then explain the condition under which it works best. That is where top-band marks are earned.

Practice Exam-Style Multiple Choice Questions for Capacity Utilisation
Q1 Which formula correctly calculates capacity utilisation?
Show the answer
Correct answer: B. Capacity utilisation compares what a business actually produces with what it could produce, then multiplies by 100 to give a percentage.
Q2 A factory can make 5,000 bikes a month and makes 3,500. What is its capacity utilisation?
Show the answer
Correct answer: B. 3,500 ÷ 5,000 = 0.7, and 0.7 × 100 = 70%. An answer above 100% would suggest the numbers have been flipped.
Q3 Why does higher capacity utilisation usually lower unit costs?
Show the answer
Correct answer: B. Fixed costs such as rent stay the same whatever the output, so producing more units means each unit carries a smaller share of those costs.
Q4 Which of the following is a risk of operating at 100% capacity utilisation?
Show the answer
Correct answer: D. At 100% there is zero slack. Any problem becomes a crisis, which is why most businesses aim for around 85% to 90%.
Practice GCSE Exam-Style Questions for Capacity Utilisation with a Case Study
Read the following case study, then answer the questions below. Underline any numbers and highlight words that tell you about demand.
Seaside Scoops is an ice cream parlour in Whitstable, run by owner Priya. Her machines can produce 12,000 scoops a month. In August she sells 11,400 scoops. In January she sells just 3,000. Priya pays £2,400 a month in rent and equipment leases. These costs stay the same all year. In summer, staff work long shifts and queues stretch down the street. One machine broke last August, and Priya lost a busy weekend of sales. A new gelato shop has opened nearby. Priya is considering two options. She could launch hot desserts, such as waffles and crêpes, for winter. Or she could reduce staff hours from October to March.
- Calculate Seaside Scoops’ capacity utilisation in January.2 marks
- Explain one disadvantage to Seaside Scoops of operating at high capacity in August.3 marks
- Analyse the impact of low capacity utilisation on Seaside Scoops’ profit in January.6 marks
- Priya is considering two options to improve winter capacity utilisation. Option 1: launch hot desserts. Option 2: reduce staff hours. Justify which option she should choose.12 marks
Answer to question 1: 3,000 ÷ 12,000 = 0.25. Then 0.25 × 100 = 25%.
Approach to question 2: name the point, use the case, then give the consequence. For example, the machine breaking led to a lost weekend of sales, so revenue fell.
Approach to question 3: build a chain. The £2,400 of fixed costs is spread over only 3,000 scoops. That is 80p per scoop, compared with around 21p in August. Higher unit costs reduce profit margins.
Exam tip for the 12-mark question: analyse both options with case evidence, then decide. Consider the new gelato competitor, the cost of new equipment, and whether winter demand for hot food exists in Whitstable. Finish with “it depends on…” to show judgement.
Practice A-Level Exam-Style Questions for Capacity Utilisation with a Case Study
Read the following case study, then answer the questions below.
Peak Fit Gyms runs 14 gyms across Yorkshire. Each gym has a maximum capacity of 2,500 members. Total membership is 26,600. The gym in Leeds city centre has 2,480 members and a waiting list. The gym in Halifax has 1,050 members. Fixed costs per gym average £38,000 a month. Leeds members complain about crowded equipment at 6pm. Two personal trainers left last quarter, citing stress. The board is considering two choices. One is closing Halifax and investing in a second Leeds site. The other is a cut-price off-peak membership across all sites. Budget gyms such as PureGym and The Gym Group compete in most of its towns.
- Calculate Peak Fit Gyms’ overall capacity utilisation. Give your answer to two decimal places.3 marks
- Explain one reason why the Leeds gym’s high capacity utilisation may reduce its profitability.4 marks
- Analyse two benefits to Peak Fit Gyms of closing the Halifax gym.9 marks
- To what extent is an off-peak membership the best way for Peak Fit Gyms to improve capacity utilisation?16 marks
- Evaluate whether high capacity utilisation is always desirable for a business.20 marks
Answer to question 1: maximum capacity = 14 × 2,500 = 35,000. Then 26,600 ÷ 35,000 = 0.76. Then 0.76 × 100 = 76.00%.
Approach to question 2: link crowding to staff departures, then to recruitment costs and lost members.
Approach to question 3: use the £38,000 fixed cost figure. Calculate Halifax’s utilisation: 1,050 ÷ 2,500 × 100 = 42%. Develop each benefit with at least three linked steps.
Approach to question 4: weigh the benefits against the risk of a price war with budget rivals. Consider whether off-peak demand exists among students or shift workers. Your judgement must be decisive, not sitting on the fence.
Exam tip for the 20-mark question: there is no case study, so use your own examples, such as airlines, hospitals and car manufacturers. Weigh cost benefits against risks to quality and flexibility. Build your conclusion around factors such as market, competition and objectives, and conclude that the ideal level usually sits below 100%.
