7+ Easy Steps: Calculate Operating Gearing Ratio

Operating leverage is determined by examining the relationship between fixed and variable costs within a company’s overall cost structure. It is typically quantified using the degree of operating leverage (DOL). One common method of calculating DOL is to divide the percentage change in operating income (or Earnings Before Interest and Taxes – EBIT) by the percentage change in revenue. Alternatively, DOL can be calculated by dividing the contribution margin (revenue minus variable costs) by the operating income. For example, if a company’s revenue increases by 10% and its operating income increases by 20%, the DOL is 2, indicating high operating leverage. This means a small change in sales can result in a larger change in profits.

Understanding a company’s cost structure and its inherent operational leverage is crucial for effective financial planning and risk management. A high degree of operating leverage can magnify profits during periods of revenue growth, but it can also amplify losses during downturns. By analyzing this leverage, businesses can make informed decisions about pricing strategies, cost control measures, and investment opportunities. Historically, industries with high fixed costs, such as manufacturing and airlines, have exhibited high operating leverage. This understanding allowed businesses in these sectors to anticipate and manage the impact of economic cycles on profitability.
