Understanding Operating Leverage
Operating leverage is a financial ratio that measures how sensitive a company's Net Operating Income (EBIT) is to its sales revenue. It highlights the relationship between fixed costs and variable costs. A company with high operating leverage has a larger proportion of fixed costs; this means that every dollar of additional revenue generates a larger increase in operating income, but it also increases the risk if sales decline.
The Operating Leverage Formula
The Degree of Operating Leverage (DOL) is typically calculated using the following formula:
Where:
- Contribution Margin = Total Sales – Total Variable Costs
- Net Operating Income (EBIT) = Contribution Margin – Total Fixed Costs
High vs. Low Operating Leverage
Companies like software developers or airline carriers usually have high operating leverage. They have massive fixed costs (R&D or aircraft maintenance) but low variable costs per customer. Once they break even, profit grows exponentially with sales.
Conversely, service-based businesses like consulting firms often have low operating leverage. Their costs (salaries) increase directly with their sales (billable hours). While they have lower risk, their profit margins stay relatively stable as they scale.
Example Calculation
Imagine a company with the following financials:
- Total Sales: $100,000
- Variable Costs: $40,000
- Fixed Costs: $30,000
First, calculate the Contribution Margin: $100,000 – $40,000 = $60,000. Next, calculate EBIT: $60,000 – $30,000 = $30,000. Finally, the DOL is $60,000 / $30,000 = 2.0. This means for every 1% increase in sales, the operating income will increase by 2%.
