Understanding Revenue Growth

Revenue growth measures how quickly a company's total sales are increasing (or decreasing) compared to a prior period — usually expressed as a percentage change year-over-year or quarter-over-quarter. The formula is simple: (Current Period Revenue − Prior Period Revenue) ÷ Prior Period Revenue. A company growing from $200 million to $250 million in a year grew revenue by 25%.

Consistent revenue growth is often read as a sign of real business strength — it suggests a company is winning more customers, selling more per customer, raising prices successfully, or some combination of the three. But growth alone doesn't tell the whole story: a company can grow revenue quickly while still losing money if its costs are growing even faster, which is common for young, fast-scaling companies investing heavily in expansion.

What matters isn't just the current growth number, but the TREND. Accelerating growth (25% this year after 15% last year) often signals building momentum, while decelerating growth (10% this year after 25% last year) can be an early warning sign, even if the current number still sounds respectable on its own. Investors also compare growth against expectations and against direct competitors — a company growing 15% might disappoint the market if analysts expected 25%, while the same 15% might thrill the market for a company where 10% was expected.
