What Is Operating Leverage? Formula, Example and Stock Analysis

# What Is Operating Leverage?

Operating leverage measures how sensitive a company's operating profit is to changes in revenue.

A company with high fixed operating costs can see EBIT rise rapidly when revenue increases, but EBIT can also fall rapidly when revenue declines.

Formula

Degree of Operating Leverage (DOL) = % Change in EBIT ÷ % Change in Revenue

A common approximation is:

DOL = Contribution Margin ÷ EBIT

Simple Example

Suppose:

Contribution = ₹400 crore.

EBIT = ₹150 crore.

Therefore:

DOL = ₹400 ÷ ₹150 = 2.67

Around that operating level, a 1% change in revenue could produce roughly a 2.67% change in EBIT, assuming the cost structure remains broadly stable.

NIFTY-Style Example

| Metric | Company A | Company B |

|---|---:|---:|

| Revenue | ₹10,000 Cr | ₹10,000 Cr |

| Variable costs | ₹7,000 Cr | ₹5,000 Cr |

| Fixed operating costs | ₹2,000 Cr | ₹4,000 Cr |

| EBIT | ₹1,000 Cr | ₹1,000 Cr |

Company B has the heavier fixed-cost structure. If revenue accelerates, EBIT can grow faster; if revenue falls, EBIT can also fall faster.

Operating vs Financial Leverage

| Operating Leverage | Financial Leverage |

|---|---|

| Driven mainly by fixed operating costs | Driven mainly by debt |

| Affects EBIT sensitivity | Affects earnings after interest |

| Business-model related | Capital-structure related |

What Investors Should Examine

Look at:

Operating leverage is not constant because costs can change over time.

Final Thoughts

The key question is not merely whether revenue is growing, but:

How much of that revenue growth is flowing through to operating profit?
