Revenue
The total amount a company earns from selling products and services — the top line of the income statement, where all earnings and valuations start.
Revenue = units sold × price per unit (summed across all products and services)
Steadily rising revenue is a sign the business is getting bigger.
In plain terms
Revenue is the total money a company received from selling goods or services. Because it sits at the very top, before a single cost is subtracted, it is called the "top line."
The income statement starts from revenue at the top and works downward, subtracting cost of sales, SG&A, interest, and taxes in turn, leaving net income at the end. That is why revenue is the starting point for all earnings.
What it tells you
Revenue shows how much of a company's product actually sells in the market — it's the most direct read on the size and reach of the business. Profit can look better for a while through cost control, but if revenue doesn't grow, growth eventually hits a ceiling.
That's why revenue is usually looked at before profit. Revenue often moves first, with profit following behind.
Formula
Revenue = units sold × price per unit (summed across all products and services)
What high or low means
Steadily rising revenue is a sign the business is getting bigger. But the revenue figure doesn't say how it rose — whether from raising prices, selling more units, or acquiring and consolidating another company. The quality differs in each case.
If revenue is growing but profit isn't following, margins tell you how much that growth cost.
How revenue is recorded (revenue recognition) differs by industry and by company. Brokerage and platform businesses may book the entire transaction value as revenue, or only the fee, so the apparent scale can look very different.
A single large contract or an acquisition can make revenue jump suddenly. Stripping out these one-off and acquisition effects and looking at "how much the existing business grew on its own (organic growth)" is what shows the real growth.
If revenue rises but only piles up as receivables while cash doesn't come in, that's a caution signal. The quality of revenue shows up in cash flow.
