What is Degree of Operating Leverage - Its Formula, Calculation and What Does It Measure (2024)

The Degree of Operating Leverage (DOL) is a financial ratio measuring the change in the operating income of a company to a change in sales. It helps predict the impact of any change in sales on company earnings. Companies or firms with a large proportion of variable costs to fixed costs have higher degrees of operating leverage and vice versa.

The Degree of Operating Leverage is also important for an investor, as it can indicate the risk of an investment and illustrates the performance of a company. Read on to learn how to calculate DOL and how different it is from financial leverage.

What is the Formula for the Degree of Operating Leverage (DOL)?

The degree of operating leverage (DOL) can be calculated using several formulas, which are as follows:

Degree of Operating Leverage = % Change in Operating Income / % Change in Sales

Or, Degree of Operating Leverage = Contribution Margin / Operating Income

Where,

• Contribution Margin = Total Sales – Total Variable Costs

Or, Degree of Operating Leverage = Q (P – V) / Q (P – V) – F

Where,

• Q = number of units
• P = price per unit
• V = variable cost per unit
• F = fixed costs

Why is the Operating Leverage Equation Important?

The calculation of operating leverage is important because it can determine the appropriate price point for covering your expenses and generating profit. It shows how businesses can effectively use fixed-cost assets like machinery, equipment, and warehousing to generate profit. In addition, if fixed assets gain more profits, operating leverage will improve.

How to Calculate the Degree of Operating Leverage (DOL)?

To calculate the degree of operating leverage, you can follow the steps below:

1. Step 1: Calculate the percent change in operating income or EBIT
   To calculate Earnings Before Interest & Taxes (EBIT), subtract the operating expense from sales. Similarly, while calculating the percentage change, divide the operating income by the opening income and then multiply by 100 to get a percentage value.
2. Step 2: Calculate the percentage change in sales.
   The calculation of percentage change in sales is similar to the first step. Here, divide the given sale value by the opening sales and multiply by 100 to achieve the percentage.
3. Step 3: Divide the percentage change in operating income or EBIT by the percentage change in sales
   Lastly, calculate DOL after getting the results from the above two steps. Here, you have to divide the change in operating income or EBIT by the change in sales.

Example of How to Use Degree of Operating Leverage (DOL)

An example to show the use of a degree of operating leverage (DOL) is as follows:

Example:

The management of XYZ Ltd. wants to calculate the current degree of operating leverage of its company. This company sells 10000 units of a product at an average price of Rs.50. Here, the variable cost per unit is Rs.12, while the total fixed cost is Rs.1,00,000.

Solution:

The degree of operating leverage of XYZ Ltd. is:

Degree of Operating Leverage = {10000 x (50 – 12)} / [{10000 x (50 – 12)} – 100000] = 1.38%

This indicates that for every 1% change in the sale of this company, the operating income will change by 1.38%

What Are the Highs and Lows in the Degree of Operating Leverage (DOL)?

A company’s degree of operating leverage can either be high or low.

A higher degree of operating leverage means that a business has a high proportion of the fixed cost. This may result in a rise in operating income due to increasing sales. However, it also indicates a higher operational risk for a business.

Similarly, a lower degree of operating leverage indicates that a business has a higher cost of variable ratio. Companies with low DOL will have low fixed expenses and more variable costs, which increases the operating profits.

To determine whether your business has a high or a low DOL, examine your organisation’s performance compared to other organisations. However, you should not be referring to every industry as some might have higher fixed costs than other industries.

What Are the Differences Between Operating Leverage and Financial Leverage?

Here are the differences between the two types of leverage ratios:

Final Word

If you have a small business, you must calculate the degree of operating leverage to maintain the bookkeeping of transactions. This will ensure periodic checking of DOL to make sure it is not changing. However, in DOL, the derived proportion of sales only works with a limited range, which may become a problem. If sales increase beyond this limit, a business may increase its production resulting in a rise in the fixed cost structure.
