What it is
Operating leverage describes how a company's profit changes in response to a change in revenue. A company with high operating leverage sees profits grow much faster than revenue — but also fall faster when revenue drops.

"Revenue 10% badha, profit 30% badha — yahi hai operating leverage ka jaadu."
Why it happens: Fixed vs variable costs
| Cost Type | Behaviour | Examples |
|---|---|---|
| Fixed costs | Same regardless of revenue | Rent, salaries, depreciation, R&D |
| Variable costs | Scale with revenue | Raw materials, logistics, sales commissions |
The magic: once revenue covers fixed costs (the breakeven point), every additional rupee of revenue flows almost entirely to profit.
Degree of Operating Leverage (DOL) = (% Change in EBIT) / (% Change in Revenue)
Example: High vs low operating leverage
| Year 1 | Year 2 (Rev +20%) | |
|---|---|---|
| Revenue | ₹1,000 Cr | ₹1,200 Cr |
| Fixed costs | ₹600 Cr | ₹600 Cr |
| Variable costs (10% of rev) | ₹100 Cr | ₹120 Cr |
| EBIT | ₹300 Cr | ₹480 Cr (+60%) |
| DOL | 3.0x |
| Year 1 | Year 2 (Rev +20%) | |
|---|---|---|
| Revenue | ₹1,000 Cr | ₹1,200 Cr |
| Fixed costs | ₹100 Cr | ₹100 Cr |
| Variable costs (80% of rev) | ₹800 Cr | ₹960 Cr |
| EBIT | ₹100 Cr | ₹140 Cr (+40%) |
| DOL | 2.0x |
The IT company has 3x operating leverage — a 20% revenue increase delivers 60% EBIT growth!
Where you see it in Indian markets
| High Operating Leverage | Low Operating Leverage |
|---|---|
| IT Services (TCS, Infosys) | Trading companies |
| Platform businesses (BSE, MCX) | Commodity traders |
| Paint companies (once capacity is set up) | Logistics (variable fuel costs) |
| Media/entertainment (production cost is fixed) | FMCG (raw materials scale with volume) |
The double edge
Leverage works both ways
In a downturn, the same DOL of 3x means a 20% revenue decline causes a 60% EBIT decline. Companies with high operating leverage are wonderful when growing and painful when shrinking.
This is why revenue visibility matters more for high-operating-leverage businesses. TCS can handle operating leverage because IT contracts provide revenue visibility. A movie production company with the same DOL is far riskier because revenue is unpredictable.
How to spot it
- Look at margin expansion during growth — if margins are expanding faster than revenue growth, operating leverage is at play
- Check employee cost + depreciation as % of revenue — if these are high and stable, fixed costs dominate
- Look at contribution margin — revenue minus variable costs only
Investment implications
- Companies with high operating leverage in a secular growth industry = powerful compounders
- Same companies in a cyclical industry = dangerous (profits evaporate in downturns)
- Look for triggers: capacity additions, new client wins, platform adoption — these unlock operating leverage
