Most small business owners know how much sales they did last year. Many also track how much sales grew compared with the previous year.
But there is another question worth asking:
How has my business really grown over the last five or ten years?
A business may grow 25% in one year, remain flat the next year and grow again after that. Looking only at year-on-year growth can therefore give an incomplete picture.
This is where CAGR, or Compound Annual Growth Rate, becomes useful.
I have been using CAGR as a metric to assess how a business has progressed over a longer period. Not just for sales, but also for profitability and other important business measures.
For an SME founder, CAGR is not merely a financial calculation.
It can serve as a simple lens for understanding whether the business is consistently moving forward.
But knowing the CAGR number alone is not enough.
The more important question is:
What is actually growing in your business: sales, profit, or both?
What does CAGR tell an SME founder about business growth?
CAGR stands for Compound Annual Growth Rate.
In simple terms, it tells you the average compounded rate at which your business has grown over a period of time.
For example, suppose your sales grew from ₹1 crore to ₹2 crore over five years.
Your CAGR is approximately 15%.
This does not mean your business grew exactly 15% every year. Some years may have been better, some slower, and there may even have been a year of decline.
But when you look at the full five-year period, the CAGR indicates that your sales would have needed to grow at approximately 15% per year, compounded, to move from ₹1 crore to ₹2 crore.
That is why I find CAGR more useful when looking at the longer-term direction of a business.
The formula is:
CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) − 1
You don’t have to calculate this manually. It can be easily calculated in Excel or with any CAGR calculator.
What matters more for a founder is not the formula.
It is what the number tells you about the direction and consistency of your business growth.
Why can year-on-year growth give an incomplete picture?
Most business owners naturally look at year-on-year growth.
“How much did we grow compared with last year?”
It is an important number. But it tells you only what happened between two years.
Suppose your sales grew like this:
Year 1: 20% growth
Year 2: 5% growth
Year 3: 18% growth
Year 4: No growth
Year 5: 12% growth
If you look only at the latest year, you may feel reasonably satisfied with 12% growth.
But what has really happened to the business over the complete five-year period?
That is where CAGR gives you a different perspective.
Year-on-year growth helps you understand what happened this year.
CAGR helps you understand the business’s longer-term growth trajectory.
I believe founders need both.
A single good year should not make us overconfident. Similarly, a difficult year should not lead us to conclude that the business is not progressing.
When we look at performance over a longer period, we get a better sense of whether the business is consistently moving forward.
Why should founders look at both sales CAGR and profit CAGR?
Many founders naturally start by looking at sales CAGR.
That is useful. But sales growth alone does not tell the complete story.
Suppose your sales have grown at a CAGR of 18% over the last five years, while your profit has grown at only 5%.
The business is certainly becoming bigger.
But is it becoming stronger?
On the other hand, if sales and profit are both growing consistently, this gives a very different picture of the business’s health.
This is why I would encourage founders to calculate at least two numbers:
Sales CAGR
Profit CAGR
Then compare them.
If sales are growing much faster than profit, it is worth asking why.
Are margins reducing?
Are operating costs increasing faster than sales?
Has additional growth created more complexity without corresponding productivity improvement?
Is the business taking on more working capital and cash flow pressure to support that growth?
These questions are more important than the CAGR number itself.
CAGR tells you what has happened over a period of time. The gap between sales growth and profit growth can tell you where to look more closely.
For an SME founder, the objective should not merely be to build a bigger business.
The business needs to become stronger as it becomes bigger.
What did my own 13-year CAGR teach me about consistent growth?
I also looked at CAGR in my own consulting business.
Over the last 13 years, my consulting business has grown at a CAGR of around 18%.
When I looked at this number, what interested me was not just the 18%.
It made me reflect on what helped me sustain this growth over a longer period.
There were years when growth was higher and years when it was lower. Like any business, the journey was not a straight line.
But over a longer period, consistent value delivery, client relationships, repeat business, continuous learning, and reinvestment in the business helped me sustain growth.
This experience reinforced one thing for me:
Consistency matters more than one or two years of exceptional growth.
A business may have a very good year because of a large order, a new customer or favourable market conditions. That is certainly positive.
But the more important question is whether the business has built the capability to sustain growth over several years.
That is why I don’t look at CAGR merely as a financial calculation.
I look at it as a reflection of what the business has built and sustained over time.
What is a good CAGR for an SME business?
This is a natural question once you calculate your CAGR.
What is a good CAGR for my business?
I don’t think there’s a single percentage that works for every SME.
A 10% CAGR may be reasonable for one business and inadequate for another.
It depends on several factors: the industry, the size and maturity of the business, the market opportunity, the competitive environment, and the investment required to support growth.
The starting base also matters.
Growing from ₹2 crore to ₹4 crore is different from growing from ₹100 crore to ₹200 crore, even though the percentage calculation may look similar.
So rather than asking only, “Is my CAGR good?”, I would encourage founders to ask:
How does our current CAGR compare with our own growth over the previous five or ten years?
Are we growing in line with the opportunity available in our market?
Is profit growing along with sales?
Are cash flow and working capital becoming healthier or more stretched as we grow?
Have our people, systems and execution capabilities become strong enough to sustain this growth?
These questions give much more meaning to the CAGR number.
A high CAGR may look impressive. But if profitability is weakening, cash is under continuous pressure, or the organisation is struggling to manage the increased scale, the growth may not be as healthy as it appears.
For me, therefore, a good CAGR is not merely a high percentage.
It is a growth rate that the business can sustain while continuing to strengthen profitability, cash flow and organisational capability.
What should an SME founder do after calculating CAGR?
Calculating CAGR is only the starting point.
The real value comes from what you do with the number.
I would suggest starting with the last five years of your business and calculating two numbers:
1. Sales CAGR
2. Profit CAGR
Put them next to each other.
If both are growing consistently, understand what has helped you achieve it and what capabilities you need to strengthen to sustain the growth.
If sales CAGR is healthy but profit CAGR is significantly lower, don’t stop with the numbers.
Ask why.
Is the issue coming from pricing, product mix, operating costs, productivity, capacity utilisation or increasing complexity in the business?
Similarly, if both sales and profit growth have remained low over several years, the question may be bigger than improving one function.
It may require a more holistic view of the business.
This is also why I see CAGR as a useful business performance indicator, but not as a standalone measure.
CAGR tells you the direction of growth. It does not tell you what is driving or restricting that growth.
To understand that, a founder needs to look at the capabilities behind the numbers: leadership, business execution, the ability to scale and the overall strength of the organisation.
This is the thinking behind my Profitable Growth Capability Framework (PGCF).
Business performance is ultimately an outcome of the capabilities a business builds and strengthens over time.
So, after calculating your CAGR, don’t stop by asking:
“What is our growth rate?”
Ask the more important question:
“What is this number telling me about my business?”
