A note before you read: Revenue growth is the first number analysts look at when a company reports earnings – before profit, before margins, before anything else. Understanding why, and what it does and doesn’t tell you, will change how you read financial results entirely.
What is revenue growth. Let me ask you something.
Imagine you own a small gym. Last year you had 200 members paying €50 a month. This year you have 300 members paying €50 a month.
Your revenue grew from €120,000 to €180,000 – a 50% increase. Business is clearly expanding. New people are choosing you over the competition. The product is working.
But here’s the question nobody asks at the celebration dinner: are you actually making more money?
Because if you hired three new staff, moved to a bigger location, bought new equipment, and ran promotions to attract those 100 new members – you might have grown revenue by 50% while your actual profit grew by almost nothing. Or went down.
Revenue growth tells you the gym is getting bigger. It doesn’t tell you whether getting bigger is making it better.
That’s the most important thing to understand about revenue growth before you ever use it as an investment filter.
So What Is Revenue Growth, Exactly?
Revenue – also called sales or turnover – is the total amount of money a company generates from its core business activities before any costs are subtracted. It’s the top line of the income statement. Everything else – costs, taxes, interest, profit – comes after it.
Revenue growth is the percentage change in that top line from one period to the next.
The formula: Revenue Growth = (Current Period Revenue − Prior Period Revenue) ÷ Prior Period Revenue × 100
If a company generated €100 million in revenue last year and €120 million this year, its revenue growth is 20%. It sold 20% more – in value terms – than it did the year before.
Simple to calculate. Widely reported. And consistently misread by investors who treat it as a proxy for profitability when it’s actually something quite different.
Revenue is what comes in the door. Profit is what stays. Revenue growth tells you the door is getting busier – not whether anything is being kept.
Why Revenue Growth Matters – Even Before Profit
Here is the nuance that makes revenue growth genuinely important, even when a company isn’t yet profitable.
Growth requires a foundation. And that foundation is revenue.
A company cannot expand into new markets, hire talent, invest in R&D, or build infrastructure without first generating meaningful and growing revenue. Revenue growth is the clearest signal that the market wants what the company is selling – that the product or service has real demand, that pricing is working, and that the business is capturing an expanding share of its opportunity.
This is why many of the most successful investments of the past two decades – Amazon, Shopify, Salesforce – were bought by investors at a time when they were growing revenue rapidly while reporting little or no profit. The investors weren’t ignoring profitability. They were betting that the revenue growth was building a foundation that would eventually convert into enormous profit at scale.
That bet proved right. It doesn’t always.
Revenue growth is a leading indicator. Profit is the lagging confirmation.
What Is a “Good” Revenue Growth Rate?
Like every metric we’ve covered in this series, revenue growth is most meaningful in context – compared to the company’s sector, its own history, and its stage of development.
| Company Stage | Revenue Growth Expectation |
|---|---|
| Early-stage growth company | 30–100%+ per year — high growth is the entire investment case |
| Mid-stage growth company | 15–30% per year — scaling but maturing |
| Large established company | 5–15% per year — steady, sustainable expansion |
| Mature blue-chip company | 2–8% per year — in line with or slightly above the economy |
| Declining company | Flat or negative — requires careful examination |
A 5% revenue growth rate at a €500 billion company is an extraordinary achievement – it means generating tens of billions in new revenue annually. The same 5% at a small-cap growth company that raised money promising 40% growth is a serious warning sign.
Always read revenue growth relative to what was expected and what is normal for that type of business.
The Difference Between Revenue Growth and Profitable Growth
This is the distinction that separates beginner investors from experienced ones – and it’s where the gym analogy from the opening comes back.
Revenue can grow for reasons that have nothing to do with building a better or more profitable business:
Discounting aggressively. A company can grow revenue rapidly by slashing prices – attracting more customers while destroying the margin on every sale. Revenue goes up. Profitability goes down.
Acquiring other companies. Revenue from acquisitions appears in the top line immediately, inflating the growth rate – even if the acquired business brings problems, debt, or operational drag that costs more than the revenue is worth.
Expanding into unprofitable markets. A company can grow revenue by entering new geographies or segments where it doesn’t yet have the scale to make money – burning cash to build a future position that may or may not materialise.
None of these are automatically bad strategies. But they produce revenue growth that looks identical on a screener to organic, profitable growth – which is what you actually want.
This is why revenue growth should always be read alongside profit margin and EPS. Revenue growth with expanding margins and growing EPS is the gold standard. Revenue growth with shrinking margins and flat or declining EPS is a business running faster to stay in the same place.

The Base Effect – Why Context Around Growth Rates Is Everything
One more thing that screeners never tell you – and that can make revenue growth figures look very different from what they actually represent.
The base effect refers to how the comparison period affects the growth rate you’re seeing.
A company that saw its revenue collapse by 50% during the pandemic and then recovered that revenue the following year would show 100% revenue growth – even though it simply returned to where it was two years earlier. The growth rate is real. The implication of explosive expansion is not.
Conversely, a company that had an exceptional year – a one-time contract, a product launch, a favourable market event – may show flat or negative growth the following year simply because the prior year was unusually strong. The “decline” doesn’t necessarily reflect a deteriorating business.
Always ask: what happened in the comparison period? A single growth rate number, stripped of that context, can tell you almost the opposite of the truth.
How Revenue Growth Fits Into Our Three Categories
Revenue growth means something different depending on which AF Core Global philosophy you’re building with.
In Fortress, we invest through broad ETFs and index funds – so individual company revenue growth matters less than the aggregate earnings growth of the market as a whole. What we watch here is GDP growth, corporate earnings trends, and whether the overall economy is expanding the revenue base that underlies the index.
In Cash Flow, moderate and consistent revenue growth is a positive signal for dividend sustainability. A company growing its revenue steadily – even at 4 or 5% annually – is building the capacity to maintain and grow its dividend payments over time. We’re not looking for explosive growth here. We’re looking for the kind of reliable, compounding expansion that keeps income investors paid through economic cycles.
In High Voltage, revenue growth is often the primary metric – because many of our picks are in earlier stages where profit margins are still developing. Here we look for high revenue growth rates, but we interrogate the quality of that growth closely: is it organic or acquired, is it at improving or deteriorating margins, and is there a credible path from strong revenue growth to eventual strong profitability?
Revenue growth starts the conversation. The other metrics determine whether it’s worth continuing.
Not blind trust. Informed choice.
What to Look For When You See Revenue Growth on a Screener
When revenue growth appears in your research, run through this sequence before drawing conclusions:
Is this organic growth or acquisition-driven? Check whether the company made significant acquisitions in the period – if it did, some of the revenue growth is purchased rather than earned.
What was the prior year comparison like? An unusually weak or unusually strong prior year distorts the growth rate in opposite directions. Context around the base period is essential.
Are margins expanding or contracting alongside the revenue growth? Growing revenue with shrinking margins is a flag. Growing revenue with stable or expanding margins is the signal you’re looking for.
Is EPS growing in line with revenue? If revenue is growing 20% but EPS is growing 5%, the growth is not converting efficiently into shareholder value. Understand why before you invest.
How does this compare to the sector? A company growing revenue at 10% in a sector growing at 2% is taking market share. The same company growing at 10% in a sector growing at 25% is falling behind.
