Examines the behaviour of total revenues, total costs and operating profit as changes occur in the output level, selling price, variable costs or fixed costs
Total costs can be divided into fixed and variable cost with respect to the output level
The behaviour of total cost and total revenues is linear (straight-line) in relation to output level
The unit selling price, unit variable cost and fixed costs are known and are constant
The analysis either covers a single product or assumes that the proportion when multiple products are sold will remain constant as the level of total units sold changes
All revenues and costs can be added and compared without taking into account the time value of money
Changes in the level of revenues and costs arise only because of changes in the number of products (or service) units produced and sold. The number of output units is the only revenue and cost driver
Organisations with a high proportion of fixed costs have a high operating leverage, so a small change in sales lead to large changes in operating profit
