In order to calculate the break-even point of a business mathematically, it is necessary to determine the gross income percentage of the business or marginal income per unit.
Example:
The marginal income ratio is calculated as follows:
Marginal income ratio = marginal income ÷ income
R80 000 ÷ 200 000 = 0.4 or 40%
The ratio can now be used to calculate the break-even point.
Break-even point in units = Tot fixed cost ÷ marginal income per unit
= R20 000 ÷ R0.80 = 25 000 units
Break-even point in rand = Tot fixed cost ÷ marginal income
= R20 000 ÷ 40% = R50 000.00
