Definition of Cost Volume Profit Analysis
Example with Formula
Cost Volume Profit analysis thinks like a number line wherein it starts with negatives, then comes 0 and then positives. Similarly, with the increasing level of sales, first will see a phase of losses, second a breakeven and third where we make profits. The first priority of any businessman is to safeguard its investment and therefore tries to save the capital shrinkages. This is possible if a business achieves the breakeven point. The question is:
How much of volume of sales/activity can achieve a breakeven point for a business?
Let’s try to understand with the help of following assumptions:
Sales Price = $15
Variable Cost = $10
Total Fixed Cost = $50,000 / year
We will first introduce another term here i.e. Contribution Margin. It is the difference between the sales price per unit and its variable cost per unit. The formula for Contribution Margin is as follows:
Contribution Margin = Price Per Unit – Variable Cost Per Unit = $15 – $10 = $5
Next, we will find Breakeven point, the following is the formula to explain this.
Breakeven point (in Units) = Total Fixed Costs / Contribution Margin = $50,000 / $5 = 10,000 Units.
So, if this business is able to sell 10,000 units in a year, it will neither make profits nor losses. So, this is the point from where it will start making profits in multiples of its contribution margin.
Units 10001 = Profit $5
Units 10002 = Profit $10
Units 10003 = Profit $15
Why is the profit increase in the multiples of contribution margin? It is because contribution margin was first utilized to cover the fixed costs of the year. Once they are covered, the whole of this margin contributes towards profit. This makes the breakeven point all the more significant because this is the grey line between making losses and earning profits.
Following are the assumptions of CVP Analysis:
No. of Units – Only Driver for Costs and Revenues
It assumes that the total variable costs and revenues would increase or decrease only due to a change in no. of units. There are no factors that will affect it.
Costs – Either Variable or Fixed
This assumption says that all the costs are either variable or fixed. In other words, it says that there are no semi-variable or semi-fixed costs.
No Change in Price, Variable Cost, and Fixed Costs
CVP analysis assumes that there are no changes in the price and variable cost per unit irrespective of change in time period and relevant range. If we see closely, it is neglecting the chances of changes in prices due to inflation, economic conditions etc. Also, neglecting the bulk order discounts and small order premiums.
If you are offered a business idea wherein you sell chairs. The first thing few things that will strike your mind is
- Required initial investment
- Amount of sales required to breakeven
- Assess whether you are capable of achieving that sale
This analysis is important because it answers the second most important question. This is not a one time question as well. This is a regular assessment. A businessman has to keep checking whether he is reaching the milestones set as per cost volume profit analysis. This will guide his decision-making process relating to increases in fixed costs, the speed of business operations etc.
- Helps managers find out a breakeven point, target operating income etc.
- Cost Volume Profit technique is used to evaluate investment proposals
- Sets the base for planning the marketing efforts of a business
- Helps in setting up the basis for budgeting activity
- In a current dynamic business environment, the costs and prices can’t remain constant throughout the year. A manager is forced to react and make necessary changes in prices and costs due to change in economic conditions, customer bargaining powers, competitors etc.
- All costs cannot be classified as fixed or variable. There is a significant list of costs which are neither fixed nor variable but are semi-variable or semi-fixed. Say, for example, a utility or electricity invoice contains rent as a component which remains constant irrespective of the change in usage of no. of electricity units.
- No. of units cannot be the only driver of total costs and revenues. There are other factors also that impact the prices as well as costs. The raw material price reduction can reduce the variable cost and therefore the customers with knowledge of this change will demand a reduction in prices as well. Similarly, the entrance of a new big player in the market forces all the firms in the market to reduce their cost or compromise or bear loss of customers.1–3
