Financial Statement Basics

Income Statement

A report card showing how much was earned and spent over a period — profit built by subtracting costs from revenue, step by step.

In plain terms

The income statement is a "report card" for one quarter (or year). Revenue (money earned) sits at the top, and you subtract costs one by one going down. So it looks like a "staircase" — the lower you go, the closer to the money actually kept.

For example, start with $100 of revenue, subtract $60 of cost to make the goods for $40 of gross profit, subtract $25 of selling costs like wages and marketing for $15 of operating income, and finally subtract $5 of interest and taxes to leave $10 of net income.

What it tells you

It shows, step by step, what a company earns money from and where it spends. Seeing which step leaks the most money reveals the company's weak spot.

What really matters is not the single net-income line but the "process by which profit is built." Even the same $10 of net income means something entirely different if earned from the core business (operating income) versus filled in by a one-off asset sale.

Formula

revenue − cost of goods sold = gross profit
gross profit − operating expenses (SG&A) = operating income
operating income ± non-operating items − taxes = net income

What high or low means

When revenue rises and the operating margin (operating income ÷ revenue) rises with it, it is read as good growth — earning more efficiently as it scales.

If revenue rises but operating income stays flat or falls, it signals that costs grow as fast as sales, leaving little behind.

Caution

Looking only at the bottom net-income line is easy to be fooled by. Net income mixes in one-off gains and losses unrelated to the core business (asset sales, lawsuit settlements) and tax effects, so operating income shows the core strength more honestly.

"Profit" is a number computed under accounting rules, so it differs from the actual cash in the bank. Sales made on credit still count as profit — so you have to read the cash flow statement alongside it to know whether that profit is real cash.

Items like depreciation are "booked as a cost even though no cash went out," which can make profit look worse or better than the actual cash situation.

Metrics to read alongside

Operating Margin

Operating income divided by revenue is the operating margin. It shows in one number how efficient the income statement's "operating-income step" is, gauging the core earning power.

Net Margin

Net income divided by revenue is the net margin. It shows how much of $100 of revenue is finally left, helping read the meaning of the income statement's bottom line.

Cash Flow Statement

Reading how much the income statement's "profit" differs from the cash flow statement's "cash" lets you check whether that profit actually reaches the bank.

Revenue (Sales)

Revenue is the income statement's top line (the starting point). Every profit step begins from this number, so reading it together shows where the report card starts.
