Revenue (Sales)
The total a company earned selling products and services — the top line of the income statement, where all profit and valuation begin.
In plain terms
Revenue is the total money a company took in selling goods or services. Before any cost is subtracted, it sits at the very top, which is why it is called the "top line."
The income statement starts from revenue at the top and subtracts cost of goods, selling/admin, interest, and taxes in turn on the way down, leaving net income at the bottom. So revenue is the starting point of all profit.
What it tells you
Revenue most directly shows how well a company's products sell in the market — its size and grip. Profit can improve briefly through cost control, but without growing revenue, growth hits a wall.
So revenue is usually looked at before profit. Revenue often moves first, with profit following.
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 growing. But "how it grew" matters — the quality differs whether by raising prices, selling more, or merging in an acquired company.
If revenue rises but profit does not follow, look at margins to check whether too much cost is being spent for that growth.
How revenue is booked (revenue recognition) differs by industry and company. Brokerage and platform firms may book the whole transaction value as revenue or only the fee, so the apparent size can look very different.
A single big contract or an acquisition can suddenly lift revenue. You have to strip out such one-off and acquisition effects to see "how much the underlying business grew on its own (organic growth)" for the real growth.
Even when revenue rises, if it only piles up as credit (receivables) without cash coming in, it is a caution signal. The quality of revenue has to be read with cash flow.
