The contribution margin is a concept used with breakeven point or in break-even analysis. In words, the contribution margin is the amount of money a company has to cover its fixed costs after it pays all of its variable expenses.ontribution Margin per unit of sales = Sales Revenue per Unit-Variable Expenses per Unit. Contribution Margin-Fixed Costs = Net Operating Profit or Loss. The break-even formula calculates the point at which a company's sales are zero-there is no profit or loss:
Break-even revenue equals fixed costs divided by contribution margin ratio, which equals contribution margin divided by total revenue. The contribution margin is equal to the difference between revenue and variable costs. Fixed costs include rent, insurance, administrative salaries, maintenance and property taxes. A small business would incur some fixed costs even if it doesn't have any revenue.
