Break Even Point


Break-Even Point is the level of sales that results in a state of no profit and no loss for the business.


Break-Even Point (Units)=Total Fixed Costs
Contribution Margin per unit


Break-Even Point is the number of sales units that cause the business to break even. Sale of 1 unit more than the break-even point will result in a profit whereas sales of 1 unit lower than the break-even Point will result in a loss for the business.

How is the Breakeven Point Formula derived?

A business breaks even when its total revenue equals its total cost. We can restate the equation to formulate the break-even point formula as follows:

Total Revenue=Total Cost
Total Revenue=Total Fixed Cost + Total Variable Cost
Total Revenue - Total Variable Cost=Total Fixed Cost
(Selling Price per Unit x Unit Sales) - (Variable Cost per Unit x Unit Sales)=Total Fixed Cost
Unit Sales x (Selling Price per Unit - Variable Cost per Unit)=Total Fixed Cost
Unit Sales x (Contribution Margin per unit)=Total Fixed Cost
Unit Sales Break-Even Point=Total Fixed Costs
Contribution Margin per unit


Sara who is the owner of a car showroom wants to know the minimum number of cars that she needs to sell in order to avoid making a loss in her first year of business.

She has provided you with the following cost and revenue estimates.

Scenario 1Scenario 2
Sales50 units100 units
  Salaries and wages$20,000$30,000

Calculate the breakeven point for Sara.

Step 1 Identify Fixed Costs

Rent and depreciation are fixed costs as they do not change with a change in sales quantity.

Step 2 Identify Semi-Variable Costs

Transportation costs are completely variable as they increase proportionate to the increase in sales quantity (i.e. transportation costs double when the sales double).

Salaries and overhead costs are semi-variable because they do not increase proportionately to the increase in sales.

Step 3 Calculate fixed cost element of semi-variable costs

Fixed cost portion of salaries and overheads can be found by using the high low method.

Total Cost - 1000 unitsA$30,000$12,000
Total Cost - 500 unitsB$20,000$10,000
Variable Cost/unitC = (A - B) /(100 units - 50 units)$200$40
Fixed CostA - C × 1000$10,000$8,000

Step 4 Calculate the total fixed costs

  Fixed Cost $
  Salaries and wages10,000
  Total Fixed Cost38,000

Step 5 Calculate sales revenue per unit

Sales revenue per unit=Total sales revenue / unit sales
=$100,000 / 100

Step 6 Calculate variable cost per unit

Variable Cost per unit $
SalariesFrom Step 3200
OverheadsFrom Step 340
Transportation$5000 / 50 units100

Step 7 Calculate Contribution Margin Per Unit

Contribution margin per unit=Sales revenue - variable cost
=$1000 - $124

Step 8 Calculate the break-even point

Break-Even Point=Total Fixed Costs
Contribution Margin per unit
=$38,000 (Step 4)
$660(Step 7)
=58 units

Sara needs to sell at least 58 units to avoid making a loss in the first year.


Break-Even Point is important to know on a basic business level because it tells how many units a business needs to sell in order to avoid a loss which can inform business decisions. Break-Even Point Analysis helps to analyze the risk of running into a loss by assessing the margin of safety. Such information can help users to make informed decisions involving for example forming minimum sales targets, feasibility analysis, shutdown decisions and risk analysis.
