Accounting: Fixed costs, Variable costs & Contribution
 

Cost-Volume-Profit Analysis

A straightforward application of this type of model is in cost-volume-profit analysis to evaluate short-term product related decisions. Although the assumptions of the model limit its practical application to very simple product settings, it does provide a useful introduction to the management accountant's approach to decision-modelling. Cost-volume-profit calculations using this model are extremely straightforward, and the results lend themselves to simple graphical illustration.

Example: A company produces a single product which has a variable cost of £20 per unit to produce, and sells for £34 per unit. If the company expects to incur fixed costs of £70,000 this year, how many units of the product must it sell this year to break-even.

 
Selling Price 34
Variable Costs (20)
Contribution 14

Break-Even is when:

Total Revenue = Total Cost
i.e. Total Revenue = Variable Cost + Fixed Cost
(Selling Price x units) = (Variable Cost per unit x units) + Fixed Costs
(Selling Price - Variable Cost per unit) x units = Fixed Costs
Contribution per unit x Units = Fixed Cost
B/E units = Fixed Costs / Contribution per unit
B/E units = 70,000 / 14 = 5,000 units
