Reading an Income Statement

The Hook

An income statement looks intimidating until you learn the one thing it actually does: it starts with all the money coming in, then walks down line by line, subtracting costs, until it lands on what the company truly kept. Once you can read it top to bottom, you can size up a business in under a minute.

Plain English

An income statement, also called a P&L (profit and loss), is a waterfall. It starts at the top with revenue, the total money earned from selling things. Then it subtracts costs in a deliberate order, and each subtraction reveals a different kind of profit. First you take out the cost of goods sold (COGS), the direct cost of making whatever you sold. What is left is gross profit, the money available to run the rest of the business. Next you subtract operating expenses, the cost of actually running the company (salaries, rent, marketing). That leaves operating income, the profit from the core business before interest and taxes. Then you take out interest on debt and taxes, and you finally reach net income, the famous bottom line, the money the company actually kept. Divide net income by the number of shares and you get earnings per share (EPS), the profit attributable to each slice of ownership. The whole statement is just that one walk down the waterfall.

The Math

Read the statement top to bottom, subtracting as you go. Each level answers a different question. Gross profit asks: is the product itself profitable? Operating income asks: is the business profitable once we run it? Net income asks: what is left after the lenders and the tax office take their share? EPS asks: how much of that belongs to each share.

• Gross profit = revenue - cost of goods sold (COGS)
• Operating income = gross profit - operating expenses
• Net income = operating income - interest - taxes
• Earnings per share (EPS) = net income / number of shares outstanding

The Lingo

Revenue

The total money a company earns from selling its products or services. The top line of the income statement.

Cost of goods sold (COGS)

The direct cost of making or buying the things you sold, such as materials and production labor.

Gross profit

Revenue minus COGS. What is left to cover everything else and still turn a profit.

Operating expenses

The costs of running the business that are not tied directly to making the product, like salaries, rent, and marketing.

Operating income

Gross profit minus operating expenses. The profit from the core business before interest and taxes.

Net income

What the company actually kept after every cost, including interest and taxes. The bottom line.

Earnings per share (EPS)

Net income divided by the number of shares outstanding. The profit that belongs to each share.

Practice

In the Room

• “Revenue is up, but I am watching gross margin, because that is where the real profitability of the product shows up.”

  Use it when

  Use this when the room is cheering a bigger top line. It signals you read past the headline to the line that actually drives profit, and it gently redirects the conversation to whether the growth is the healthy kind.

  Tap to flip back

• “Operating income is the number I trust most here, because it strips out one-time interest and tax effects and shows how the core business is really performing.”

  Use it when

  Bring this out when someone leans hard on net income to make a point. It shows you know that interest and taxes can distort the bottom line, and that the core business lives one level up.

  Tap to flip back

• “EPS grew, but it was partly from buying back shares, not from earning more, so let us be precise about what improved.”

  Tap to see when to use it

  Use it when

  Use this when EPS is being celebrated without context. It proves you understand that a smaller share count can lift EPS even when actual profit is flat, which is exactly the nuance that earns trust.
