What Is Operating Leverage?
Operating leverage is a cost-accounting formula that measures the degree to which a firm or project can increase operating income by increasing revenue. A business that generates sales with a high gross margin and low variable costs has high operating leverage.
The higher the degree of operating leverage, the greater the potential danger from forecasting risk, in which a relatively small error in forecasting sales can be magnified into large errors in cash flow projections.
The Operating Leverage And DOL
The Formula for Operating Leverage Is
Degree of operating leverage=ProfitContribution margin
This can be restated as:
Degree of operating leverage=Q∗CM−Fixed operating costsQ∗CMwhere:Q=unit quantityCM=contribution margin (price - variable cost per unit)
- Operating leverage is a cost-accounting formula that measures the degree to which a firm or project can increase operating income by increasing revenue.
- Companies with high operating leverage must cover a larger amount of fixed costs each month regardless of whether they sell any units of product.
- Low-operating-leverage companies may have high costs that vary directly with their sales but have lower fixed costs to cover each month.
Calculating Operating Leverage
For example, Company A sells 500,000 products for a unit price of $6 each. The company’s fixed costs are $800,000. It costs $0.05 in variable costs per unit to make each product.
Calculate company A’s degree of operating leverage as follows:
A 10% revenue increase should result in a 13.7% increase in operating income (10% x 1.37 = 13.7%).
What Does Operating Leverage Tell You?
The operating leverage formula is used to calculate a company’s break-even point and help set appropriate selling prices to cover all costs and generate a profit. The formula can reveal how well a company is using its fixed-cost items, such as its warehouse and machinery and equipment, to generate profits. The more profit a company can squeeze out of the same amount of fixed assets, the higher its operating leverage.
One conclusion companies can learn from examining operating leverage is that firms that minimize fixed costs can increase their profits without making any changes to the selling price, contribution margin, or the number of units they sell.
High and Low Operating Leverage
It is important to compare operating leverage between companies in the same industry, as some industries have higher fixed costs than others. The concept of a high or low ratio is then more clearly defined.
Most of a company’s costs are fixed costs that recur each month, such as rent, regardless of sales volume. As long as a business earns a substantial profit on each sale and sustains adequate sales volume, fixed costs are covered and profits are earned.
Other company costs are variable costs that are only incurred when sales occur. This includes labor to assemble products and the cost of raw materials used to make products. Some companies earn less profit on each sale but can have a lower sales volume and still generate enough to cover fixed costs.
For example, a software business has greater fixed costs in developers’ salaries and lower variable costs in software sales. As such, the business has high operating leverage. In contrast, a computer consulting firm charges its clients hourly and doesn't need expensive office space because its consultants work in clients' offices. This results in variable consultant wages and low fixed operating costs. The business thus has low operating leverage.
Examples of Operating Leverage
Most of Microsoft’s costs are fixed, such as expenses for upfront development and marketing. With each dollar in sales earned beyond the break-even point, the company makes a profit, but Microsoft has high operating leverage.
Conversely, Walmart retail stores have low fixed costs and large variable costs, especially for merchandise. Because Walmart sells a huge volume of items and pays upfront for each unit it sells, its cost of goods sold increases as sales increase. Because of this, Walmart stores have low operating leverage.
