Understanding Business Risk, Profit Power & Capital Structure with Solved Examples
Leverage in finance means using fixed costs to magnify returns. Businesses use two major types of leverage: Operating Leverage and Financial Leverage. While both increase potential profits, they also increase risk. Understanding the difference is essential for finance students, managers, and investors.
What is Operating Leverage?
Operating leverage arises from fixed operating costs such as rent, salaries, depreciation, and insurance. It measures how sensitive a company’s Operating Income (EBIT) is to changes in sales. When a company has high fixed costs and low variable costs, even a small change in sales can significantly affect operating profit.
Formula:
Degree of Operating Leverage (DOL) = Contribution / EBIT
Where:
Contribution = Sales – Variable Costs
High fixed costs lead to higher operating leverage. This increases potential profits during good sales periods but also increases losses when sales decline. Therefore, operating leverage represents business risk arising from cost structure.
Practical Example – Operating Leverage
Suppose a company has:
Sales = $100,000
Variable Costs = $60,000
Fixed Costs = $20,000
Step 1: Contribution = 100,000 – 60,000 = 40,000
Step 2: EBIT = 40,000 – 20,000 = 20,000
Step 3: DOL = 40,000 / 20,000 = 2
This means a 10% increase in sales will increase EBIT by 20% (2 × 10%). Likewise, a 10% decrease in sales would reduce EBIT by 20%. This shows how operating leverage amplifies operating profit fluctuations.
What is Financial Leverage?
Financial leverage arises from fixed financial costs, mainly interest on debt. It measures how sensitive Net Income (or Earnings Per Share) is to changes in EBIT. Companies that use borrowed funds must pay interest regardless of business performance.
Formula:
Degree of Financial Leverage (DFL) = EBIT / EBT
Where:
EBT = EBIT – Interest
Higher debt leads to higher financial leverage. While it can increase returns to shareholders when profits rise, it also increases financial risk if profits fall.
Practical Example – Financial Leverage
Continuing from the previous example:
EBIT = 20,000
Interest = 5,000
Step 1: EBT = 20,000 – 5,000 = 15,000
Step 2: DFL = 20,000 / 15,000 = 1.33
This means a 10% increase in EBIT will increase Net Income by 13.3% (1.33 × 10%). However, if EBIT decreases, Net Income will decline at a faster rate due to fixed interest obligations.
Financial leverage therefore represents financial risk arising from capital structure decisions.
Key Differences
Operating Leverage is related to fixed operating costs, while Financial Leverage is related to fixed financial costs.
Operating Leverage measures the impact of sales changes on EBIT, while Financial Leverage measures the impact of EBIT changes on Net Income.
Operating Leverage reflects business risk, whereas Financial Leverage reflects financial risk.
Operating Leverage is controlled through cost structure decisions, while Financial Leverage is controlled through debt-equity decisions.
Combined Leverage
When a company uses both high operating and financial leverage, total risk increases significantly.
Degree of Combined Leverage (DCL) = DOL × DFL
From our example:
DCL = 2 × 1.33 = 2.66
This means a 10% increase in sales will result in a 26.6% increase in Net Income. While this magnifies profits, it also magnifies losses.
In conclusion, Operating Leverage focuses on operational cost structure, while Financial Leverage focuses on financing strategy. Both are powerful tools, but they must be managed carefully to balance profitability and risk.
