Operating Leverage and Financial Leverage Explained

Updated 11 October 2026 · Fact-checked

Leverage measures how a fixed cost magnifies a change in profit. Operating leverage (DOL = Contribution ÷ EBIT) shows how sales changes affect EBIT. Financial leverage (DFL = EBIT ÷ EBT) shows how EBIT changes affect EPS. Combined leverage (DCL = DOL × DFL = Contribution ÷ EBT) links sales to EPS.

Understand Operating Leverage and Financial Leverage

Leverage means using a fixed cost to magnify results. Think of a lever: a small push on one end moves the other end a lot. In finance, the fixed cost is the pivot. If sales rise, a firm with high fixed costs sees profit rise by a much larger percentage. The same is true when sales fall, so leverage raises both gain and risk.

Operating leverage comes from fixed operating costs such as rent, salaries and depreciation. Because these costs do not change with sales, a 10% rise in sales can lift EBIT by much more than 10%. It sits between sales and EBIT. The degree of operating leverage (DOL) tells you the multiple.

Financial leverage comes from fixed financial costs: interest on debt and preference dividend. These are paid whatever EBIT is. So a small change in EBIT causes a larger change in EPS. It sits between EBIT and EPS. The degree of financial leverage (DFL) tells you the multiple.

Combined leverage joins the two. It shows how a change in sales flows all the way to EPS. A firm with both high fixed operating cost and high debt is risky, because a small fall in sales can wipe out earnings for shareholders.

A DOL of 3 means: if sales rise 10%, EBIT rises 30%. The figure applies only at the sales level where you computed it, and only while fixed costs stay fixed.

Key rules to remember

Contribution: Contribution = Sales − Variable cost; Fixed cost is not deducted here.
EBIT: EBIT = Contribution − Fixed operating cost; Interest is not deducted yet.
Degree of operating leverage: DOL = Contribution ÷ EBIT = % change in EBIT ÷ % change in sales; Fixed operating cost excludes interest.
Degree of financial leverage: DFL = EBIT ÷ EBT = EBIT ÷ (EBIT − Interest); With preference shares: DFL = EBIT ÷ [EBIT − Interest − Pref. dividend ÷ (1 − t)].
Degree of combined leverage: DCL = DOL × DFL = Contribution ÷ EBT = % change in EPS ÷ % change in sales; EBT is EBIT less interest.
EPS: EPS = (EBT − Tax − Preference dividend) ÷ Number of equity shares; Use to verify leverage results.

How to solve Operating Leverage and Financial Leverage questions

Work down the income statement in a fixed order. Most leverage questions become simple once you build it.

1List sales, variable cost, fixed operating cost, interest, preference dividend, tax rate and number of shares.
2Compute contribution = sales − variable cost.
3Compute EBIT = contribution − fixed operating cost.
4Compute EBT = EBIT − interest.
5Compute DOL = contribution ÷ EBIT and DFL = EBIT ÷ EBT.
6Compute DCL = DOL × DFL, and check it equals contribution ÷ EBT.
7If asked for the effect of a change, multiply the percentage change in sales by the relevant degree.
8Write a one-line interpretation: what the figure means and what it says about risk.

Quickest way: Three-line shortcut

When to use it: Use when the question gives sales, variable cost, fixed cost and interest and asks for the degrees.

Write only three numbers: Contribution, EBIT, EBT.
DOL = Contribution ÷ EBIT; DFL = EBIT ÷ EBT; DCL = Contribution ÷ EBT.
For a percentage change in EPS, multiply the percentage change in sales by DCL.

Common mistakes in Operating Leverage and Financial Leverage

Deducting fixed cost when finding contribution.
Students confuse contribution with EBIT.
Fix: Contribution = Sales − Variable cost only. Fixed cost comes off next to give EBIT.
Including interest in fixed operating cost for DOL.
The word 'fixed' is read as covering all fixed charges.
Fix: Interest belongs to financial leverage. Keep it out of EBIT.
Using EBT instead of EBIT as numerator in DFL.
Both are profit figures near the bottom of the statement.
Fix: DFL = EBIT ÷ EBT. EBIT on top, EBT below.
Ignoring preference dividend in DFL.
Students treat only interest as fixed financial cost.
Fix: Divide preference dividend by (1 − tax rate) to make it pre-tax, and add it to interest in the denominator.
Applying a degree computed at one sales level to a very different level.
DOL is treated as a constant.
Fix: Recompute leverage at each new level of sales. The degree holds for small changes from the base.
Giving a number with no interpretation.
Students stop once the calculation is done.
Fix: Add a line: a DOL of 2.5 means a 1% change in sales changes EBIT by 2.5%.

Worked examples

Example 1

A company has sales of ₹10,00,000, variable cost of ₹6,00,000, fixed operating cost of ₹2,00,000 and interest of ₹50,000. Calculate DOL, DFL and DCL. If sales rise by 10%, find the percentage rise in EBIT and in EBT.

Show the solution

Contribution = 10,00,000 − 6,00,000 = ₹4,00,000.
EBIT = 4,00,000 − 2,00,000 = ₹2,00,000.
EBT = 2,00,000 − 50,000 = ₹1,50,000.
DOL = 4,00,000 ÷ 2,00,000 = 2.
DFL = 2,00,000 ÷ 1,50,000 = 1.333.
DCL = 2 × 1.333 = 2.667; check: 4,00,000 ÷ 1,50,000 = 2.667.
EBIT rises by 10% × 2 = 20%.
EBT (and so EPS, with no preference shares and a constant tax rate) rises by 10% × 2.667 = 26.67%.

Answer: DOL = 2, DFL = 1.33, DCL = 2.67. A 10% rise in sales raises EBIT by 20% and EBT by about 26.67%.

Example 2

Sales are ₹20,00,000. Variable cost is 60% of sales. Fixed operating cost is ₹5,00,000. The company has 10% debentures of ₹10,00,000. Tax rate is 30%. There are 20,000 equity shares. Find the three degrees of leverage and EPS. Interpret the combined leverage.

Show the solution

Variable cost = 60% × 20,00,000 = ₹12,00,000.
Contribution = 20,00,000 − 12,00,000 = ₹8,00,000.
EBIT = 8,00,000 − 5,00,000 = ₹3,00,000.
Interest = 10% × 10,00,000 = ₹1,00,000.
EBT = 3,00,000 − 1,00,000 = ₹2,00,000.
Tax at 30% = ₹60,000; profit after tax = ₹1,40,000.
EPS = 1,40,000 ÷ 20,000 = ₹7.
DOL = 8,00,000 ÷ 3,00,000 = 2.667.
DFL = 3,00,000 ÷ 2,00,000 = 1.5.
DCL = 2.667 × 1.5 = 4; check: 8,00,000 ÷ 2,00,000 = 4.

Answer: DOL = 2.67, DFL = 1.5, DCL = 4, EPS = ₹7. A DCL of 4 means a 1% change in sales changes EPS by 4% in the same direction, so the company carries high risk.

Exam tips

Always show contribution, EBIT and EBT as separate lines. Marks are given for each step even if the final figure is off.
Write the formula before substituting numbers.
Add a short interpretation and a comment on risk. Descriptive papers reward it.
If asked for the difference between operating and financial leverage, state the cost type, the profit link and the risk each one creates.
If a question mentions preference shares, check whether the dividend must be grossed up for tax before using it in DFL.

Operating Leverage and Financial Leverage: frequently asked questions

What is the difference between operating leverage and financial leverage?

Operating leverage arises from fixed operating costs and links sales to EBIT. Financial leverage arises from fixed financial costs, such as interest, and links EBIT to EPS. Operating leverage reflects business risk. Financial leverage reflects financial risk.

What does a DOL of 4 mean?

It means a 1% change in sales changes EBIT by 4% in the same direction. It is valid near the sales level used to compute it. A higher DOL means higher business risk.

Is combined leverage the sum or the product of DOL and DFL?

It is the product: DCL = DOL × DFL. This equals contribution ÷ EBT. Do not add the two degrees.

Can leverage be negative or undefined?

If EBIT is zero, DOL is undefined. If EBIT is below the fixed financial charges, EBT is negative and DFL turns negative. In such cases, explain that the firm is at or below its break-even level and the degree has little use.
