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:

These costs are constant across all possible unit volumes. 3  Thirdly, Variable costs. The variable cost total varies by unit volume.
