Operating Income Calculator
Calculate Operating Income (EBIT) from revenue, COGS, and operating expenses.
Understand the difference between EBIT, EBITDA, and net income.
Operating Income Formula
Operating Income — also called EBIT (Earnings Before Interest and Taxes) — measures how much profit a company generates from its core business operations, before the effects of financing decisions and tax jurisdictions.
Method 1: From Revenue:
Operating Income = Revenue − COGS − Operating Expenses (SG&A, R&D, etc.)
Method 2: From Gross Profit:
Operating Income = Gross Profit − Operating Expenses
Where:
- Gross Profit = Revenue − Cost of Goods Sold (COGS)
- Operating Expenses = SG&A (Selling, General & Administrative) + R&D + Depreciation & Amortization
What is Included vs Excluded
INCLUDED in Operating Income calculation:
- All revenue from products/services
- COGS (direct production costs)
- SG&A (salaries, rent, marketing, administration)
- R&D expenses
- Depreciation and amortization
EXCLUDED from Operating Income (come after EBIT):
- Interest expense / income
- Income tax expense
- One-time gains/losses (asset sales, lawsuit settlements)
- Investment income
EBIT vs EBITDA vs Net Income
| Metric | What it Includes | Best Used For |
|---|---|---|
| Gross Profit | Revenue − COGS only | Pricing efficiency |
| EBIT (Operating Income) | All operating costs | Core operations comparison |
| EBITDA | EBIT + D&A added back | Cash generation proxy |
| Net Income | Everything incl. interest & tax | Bottom-line profitability |
Why EBIT Matters for Cross-Company Comparisons
EBIT removes two factors that differ between companies for non-operational reasons:
- Interest expense varies based on how much debt a company carries (financing choice).
- Tax expense varies by country, tax elections, and carried losses.
By comparing EBIT, you compare operational efficiency only — how well each company converts revenue into profit from its core business.
Operating Leverage
Operating Leverage = % Change in EBIT ÷ % Change in Revenue
High operating leverage means a small revenue increase produces a large profit increase — and vice versa. Companies with high fixed costs (airlines, manufacturers) have high operating leverage.
Worked Example
A software company annual figures:
- Revenue: $12,000,000
- COGS: $2,400,000
- R&D: $1,800,000
- SG&A: $2,200,000
- Depreciation: $400,000
- Gross Profit = $12,000,000 − $2,400,000 = $9,600,000 (80% gross margin)
- Total OPEX = $1,800,000 + $2,200,000 + $400,000 = $4,400,000
- Operating Income (EBIT) = $9,600,000 − $4,400,000 = $5,200,000
- Operating Margin = $5,200,000 ÷ $12,000,000 = 43.3% (excellent for software)
Pro Tips
- Track operating income (not just net income) across quarters: net income swings wildly with one-time items and tax events.
- Lenders and private equity buyers typically value businesses at a multiple of EBIT or EBITDA.
- A company with improving gross margin but declining EBIT has rising overhead: an expense control problem.
