Fixed costs are costs that do not change with the level of output. Rent, business rates, insurance and salaried staff are typical fixed costs.

What is a semi-variable cost?

A semi-variable cost has a fixed element and a variable element. A mobile phone contract with a monthly line rental plus a charge per call is semi-variable.

Give an example of a semi-variable cost in a delivery business and explain both parts.

A delivery van carries fixed annual road tax and insurance whatever the mileage. Fuel is the variable element because fuel spending rises with every mile driven.

A workshop pays £300 a month for machine hire plus £2 for every hour the machine runs. Calculate the cost of a month in which the machine runs for 250 hours.

The variable element is 250 × £2, which comes to £500. The fixed hire charge of £300 is then added, so the total cost is £800.

Explain what happens to fixed cost per unit as output rises.

Fixed cost per unit falls as output rises because the same total fixed cost is spread over more units. A business producing 10,000 units carries a lower fixed cost per unit than one producing 1,000.
