Fixed costs are costs that do not change according to the amount of goods produced/sold. Be careful - this does not mean that they never change – but they do not change in proportion to the amount of goods/services a business produces or sells. Rent is one example.

Total costs are all costs added together

Total costs = variable costs + fixed costs
