Part 1 of 2

Revenue growth shows how fast a company's total sales are changing compared to a previous period. It’s usually expressed as a percentage change, either year-over-year or quarter-over-quarter. The formula is straightforward: (Current Period Revenue − Prior Period Revenue) ÷ Prior Period Revenue. For example, if a company grows from $200 million to $250 million in a year, it has a revenue growth of 25%.

Consistent revenue growth is often seen as a sign of strong business performance. It means a company is gaining more customers, selling more to each customer, raising prices effectively, or some mix of these. But growth alone doesn’t tell the full story. A company can increase revenue quickly while still losing money if its costs rise even faster. This scenario is common for young companies that are rapidly scaling and investing heavily in growth.

SeasonalityOnly the year-on-year number is growth. The other is mostly the season.

What matters is not just the current growth figure but the TREND. Accelerating growth, like 25% this year after 15% last year. Often shows momentum. On the flip side, decelerating growth, such as 10% this year after 25% last year. Can be an early warning sign, even if the current number seems fine. Investors also measure growth against expectations and competitors. A company growing at 15% might disappoint if analysts were expecting 25%. Conversely, that same 15% might excite investors if 10% was what they expected.

Insider Angle: A slowing growth rate doesn’t always mean a company is doing worse overall. For instance, a company growing 10% from a $50 billion revenue base adds $5 billion in new sales. That’s often more in dollar terms than a smaller company growing 50% from a $200 million base, which adds just $100 million. Percentage growth and dollar growth tell different parts of the same story, and mixing them up is a common mistake in analysis.
Try This: Look up a company's revenue for its last two fiscal years (you can find this easily in any earnings report or company overview). Calculate the year-over-year growth rate yourself, then see if you can find the growth rate that analysts were expecting for comparison.
