Operating income, also called operating profit or EBIT (Earnings Before Interest and Taxes), represents the profit generated from core business operations after deducting all operating expenses from gross profit. This metric isolates the profitability of the business itself, excluding financing decisions (interest) and tax jurisdiction effects, making it ideal for comparing operational performance across companies.

The calculation:

Operating Income = Revenue - Cost of Revenue - Operating Expenses
or
Operating Income = Gross Profit - SG&A - R&D - D&A - Other Operating Expenses

Why operating income matters:

Core profitability: Shows whether the business model generates profit from operations
Comparison tool: Removes financing and tax differences for peer comparison
Management assessment: Measures operational execution before capital structure effects
Debt capacity: Interest coverage calculated from operating income

Operating margin:

Operating Margin = Operating Income / Revenue × 100

Industry benchmarks:

Software: 20-35% operating margins for mature companies
Consumer goods: 10-20% operating margins
Retail: 3-8% operating margins
Airlines: 5-15% in good years; negative in downturns
Utilities: 15-25% operating margins

Analysing operating income:

Margin trends: Improving, stable, or declining over time?
Revenue leverage: Does operating income grow faster than revenue?
Peer comparison: Above or below industry average?
Volatility: Stable margins indicate business resilience

EBIT vs. Operating Income:

Usually identical: For most companies, these terms are interchangeable
Difference: Non-operating items like gains/losses on asset sales may appear above or below the operating income line depending on presentation

Key relationships:

Interest coverage: Operating Income / Interest Expense; higher is safer
EBITDA derivation: Operating Income + Depreciation + Amortisation

Operating income must cover interest expenses and taxes while leaving profit for shareholders. A company with negative operating income is losing money on core operations—an unsustainable situation without a clear path to profitability.
