Operating Leverage
Operating leverage arises when a company has fixed operating expenses that remain constant regardless of sales volume. It essentially amplifies the impact of changes in sales on a company's earnings before interest and taxes (EBIT), also known as operating profit.
Core Concepts
- Fixed Operating Costs: Expenses that do not change with sales volume (e.g., rent, salaries, depreciation). These costs must be paid regardless of revenue.
- Variable Operating Costs: Expenses that vary directly with sales volume (e.g., raw materials, direct labor).
- Semi-Variable (or Semi-Fixed) Costs: Expenses with both fixed and variable components (e.g., utilities that have a fixed base charge plus usage fees). These are often split into their fixed and variable elements for analysis.
- Magnified Effect: With operating leverage, a percentage change in sales leads to a larger percentage change in EBIT. This works both ways – profits can soar if sales increase, but losses can also deepen if sales decline.
The Definition of Operating Leverage
Operating leverage is a company's ability to use fixed operating costs to magnify the effects of changes in sales on its EBIT. It exists whenever a company has fixed costs that must be met regardless of sales volume.
Example: Illustrating Operating Leverage
A firm sells a product for Rs 100 per unit, has variable operating costs of Rs 50 per unit, and fixed operating costs of Rs 50,000 per year. Let's examine EBIT at different sales levels:
| Sales Level (Units) | Sales Revenue (Rs) | Variable Costs (Rs) | Contribution Margin (Rs) | Fixed Costs (Rs) | EBIT (Rs) | % Change in Sales | % Change in EBIT |
|---|---|---|---|---|---|---|---|
| 1,000 | 100,000 | 50,000 | 50,000 | 50,000 | 0 | -50% from base | -100% from base |
| 2,000 (Base) | 200,000 | 100,000 | 100,000 | 50,000 | 50,000 | - | - |
| 3,000 | 300,000 | 150,000 | 150,000 | 50,000 | 100,000 | +50% from base | +100% from base |
Observations:
- Increase in Sales: A 50% increase in sales (from 2,000 to 3,000 units) results in a 100% increase in EBIT (from Rs 50,000 to Rs 100,000).
- Decrease in Sales: A 50% decrease in sales (from 2,000 to 1,000 units) results in a 100% decrease in EBIT (from Rs 50,000 to zero).
Measuring Operating Leverage: Degree of Operating Leverage (DOL)
The Degree of Operating Leverage (DOL) provides a quantitative measure of the extent to which operating leverage is being used.
- DOL Definition: The percentage change in EBIT for a given percentage change in sales.
- Formula: DOL = (% Change in EBIT) / (% Change in Sales)
An alternative formula is:
- DOL Definition: Contribution Margin / EBIT
Key point: the higher the DOL, the higher the operating leverage.
If you have no fixed costs, there is no Operating Leverage.
Impact and Risk
- High Operating Leverage (High DOL): Greater potential for profits when sales are increasing, but greater risk of losses when sales are decreasing.
- Low Operating Leverage (Low DOL): More stable earnings but less potential for rapid profit growth.
Operating Risk: The risk that a company won't be able to cover its fixed operating costs. The higher the fixed costs, the larger the sales volume needed to reach the breakeven point (where total revenue equals total costs).
