What it measures
Revenue (also called sales or the top line) is the money a company takes in from customers before any costs. Revenue growth is the percentage change from one period to the same period a year earlier.
Nothing else in the financial statements can grow for long without it. Costs can be cut and shares can be bought back, but lasting earnings growth needs sales growth underneath.
Trailing (TTM) versus forward
- Trailing twelve months (TTM) adds up the last four reported quarters and compares them with the four before. It is fact, but it looks backwards. See TTM revenue growth in the glossary.
- Forward (FWD) is the analysts' consensus for the next twelve months. It is an estimate, but it is what the stock price is actually betting on. See forward revenue growth in the glossary.
| Profile | TTM | Forward | Reading |
|---|---|---|---|
| Accelerating | 12% | 20% | Growth is expected to speed up, often a new product cycle |
| Steady compounder | 18% | 17% | Durable, predictable growth |
| Decelerating | 30% | 12% | Expectations are falling; the price may already reflect this |
What strong looks like
| Rating | Growth |
|---|---|
| Strong | Above 15% |
| Good | 8% to 15% |
| Weak | Below 8% |
Context matters. A software company at 10% is slow; a railroad at 10% is fast.
The deceleration warning
Watch the trend across quarters, not a single number. A sequence like +20%, +15%, +10%, +5% is the classic warning sign: each quarter still shows growth, but the business is slowing, and the stock is usually priced for the old rate. Deceleration often shows up in revenue before it shows up in earnings.
Caveats
- Acquisitions can inflate growth. Check organic growth in the report.
- Currency swings move reported revenue for global companies.
- One-off contracts can create a single strong year.
Pair revenue growth with Gross margin (is the growth profitable?) and EPS growth (TTM and forward) (is it reaching shareholders?).
Questions
What is a good revenue growth rate?
For a growth company, above 15% a year is strong and above 25% is exceptional. Below 8% is slow for a company priced as a grower. Mature companies can be fine at 3 to 6% if margins and cash flow are strong.
Is TTM or forward revenue growth better?
Use both. TTM is what actually happened; forward is what analysts expect. Forward above TTM means growth is expected to accelerate; well below means it is expected to slow.
