Break-even analysis and cost-volume-profit analysis

CVP analysis looks at the effect of sales volume variations on costs and operating profit. The analysis is based on the classification of expenses as variable (expenses that vary in direct proportion to sales volume) or fixed (expenses that remain unchanged over the long term, irrespective of the sales volume). Accordingly, operating income is defined as follows:

Operating Income = Sales – Variable Costs  Fixed Costs

A CVP analysis is used to determine the sales volume required to achieve a specified profit level. Therefore, the analysis reveals the break-even point where the sales volume yields a net operating income of zero and the sales cutoff amount that generates the first dollar of profit.

Cost-volume profit analysis is an essential tool used to guide managerial, financial and investment decisions.

COST-VOLUME PROFIT ANALYSIS

Contribution Margin and Contribution Margin Percentage

The first step required to perform a CVP analysis is to display the revenue and expense line items in a Contribution Margin Income Statement and compute the Contribution Margin Ratio.
