Operating income is what's left after you subtract both COGS and operating expenses from revenue. It's the profit from core business operations before interest payments and taxes enter the picture.
Also called EBIT (Earnings Before Interest and Taxes), operating income is arguably the most useful profit metric for marketing strategy because it includes all the costs marketing can influence (revenue, COGS structure through product mix, and marketing spend itself) while excluding costs marketing can't control (debt structure, tax strategy).
The Formula
Operating Income = Gross Profit - Operating Expenses
Or equivalently:
Operating Income = Revenue - COGS - Operating Expenses
The P&L Flow
Step | Calculation | Result |
Revenue | $10,000,000 | |
Less: COGS | -$3,000,000 | |
Gross Profit | $7,000,000 | |
Less: Sales & Marketing | -$2,500,000 | |
Less: R&D | -$1,500,000 | |
Less: G&A | -$1,000,000 | |
Operating Income | $2,000,000 | |

Why Operating Income Is the Right Marketing Metric
It captures marketing's full impact. Revenue contribution (positive) and marketing expense (negative) both show up in operating income. A campaign that drives $500K in revenue at 60% gross margin generates $300K in gross profit. If the campaign cost $100K, the net operating income contribution is $200K.
It's comparable across companies. Different companies have different tax situations and capital structures, which makes net income harder to compare. Operating income isolates business performance from financial engineering.
It reveals operating leverage. When operating income grows faster than revenue, the business is gaining leverage. Marketing that drives revenue growth without proportional spending increases creates operating leverage.
Operating Income vs. EBITDA
Metric | Includes D&A? | Best For |
Operating Income (EBIT) | Yes | True operational profitability |
EBITDA | No (adds it back) | Cash generation comparison, especially for capital-intensive businesses |
SaaS companies often report EBITDA because capitalized development costs create significant amortization that isn't a cash expense. Hardware companies report operating income because depreciation of manufacturing equipment represents real economic cost.
Frequently Asked Questions
What's a good operating income margin?
SaaS: 15-30%. Consumer goods: 10-20%. Retail: 3-8%. Financial services: 25-40%. Compare to industry benchmarks and track your trend over time.
How does marketing investment affect operating income?
Marketing spend reduces operating income directly (it's an operating expense). Marketing-driven revenue increases operating income through gross profit contribution. The net effect depends on whether gross profit generated exceeds marketing spend.
Can operating income be negative while gross profit is positive?
Yes, and it's common in growth-stage companies. Positive gross profit means the core product is priced above cost. Negative operating income means the company is spending more on growth (marketing, R&D, sales) than gross profit can cover. This is the deliberate trade-off of investing in scale.
