What it means
The calculation compares one period against another, most often this year against last year or this quarter against the same quarter a year earlier. Comparing against the same period a year ago matters because it strips out seasonal patterns; a garden centre comparing spring with winter would produce a meaningless number.
The result is a percentage that can be tracked over time and compared across companies of very different sizes. Sales growth is the number boards, investors and lenders look at first, because it signals demand for what the business sells.
It also drives valuations directly, since a business growing sales at 30% a year is usually worth a much higher multiple of its earnings than one growing at 3%. Bonus schemes, sales commissions and covenant tests are frequently tied to it.
The important nuance is that headline growth can come from several very different sources. Selling more units, raising prices, acquiring another business and moving into a new country all increase sales, but only some of them indicate genuine underlying demand.
Serious analysts split growth into organic growth, which excludes acquisitions, and like for like or same store growth, which excludes new sites opened during the period. Growth also has to be judged against its cost.
A company can buy almost any growth rate through heavy discounting or expensive advertising, so sales growth is usually read alongside gross margin and customer acquisition cost. Rising sales with falling margin is a warning sign rather than a success.
Over longer horizons, the compound annual growth rate is the better measure because it smooths out lumpy years into a single average rate. A run of 40%, then 5%, then 15% growth tells a more complicated story than the three year average alone, so most reports show both.
In practice
Real-world examples.
Example
A regional coffee chain reports 18% sales growth, but 15 percentage points of that came from opening nine new sites. Like for like growth at existing stores was 3%, which changes the board's view of how well the format is actually performing.
Example
A software business grows sales 45% while its gross margin drops from 78% to 64% because it discounted heavily to win enterprise logos. The finance director flags that the growth is being purchased rather than earned.
Example
An industrial parts supplier reports flat sales growth of 0% in a year when it raised prices 6%, which means unit volumes fell by roughly the same amount. Management treats the result as a volume problem rather than a pricing success.
Think of it
“Sales growth is simply how much your revenue is increasing-the pace of business expansion.
Formula
Calculation
Sales growth % = (current period sales - prior period sales) / prior period sales x 100
A specialist food distributor recorded sales of $7,000,000 last financial year and $8,400,000 this year.
Sales growth = ($8,400,000 - $7,000,000) / $7,000,000 x 100 = $1,400,000 / $7,000,000 x 100 = 20%.
The same business can run the calculation quarterly. If the quarter just ended produced $2,200,000 against $2,000,000 in the same quarter last year, growth is ($2,200,000 - $2,000,000) / $2,000,000 x 100 = 10%, showing that the annual rate of 20% is slowing as the year progresses.Case study
Seen in the real world.
This illustrative and fictional example features Marlow Outdoor, an invented camping equipment retailer. Marlow reported sales growth of 26% for the year, taking revenue from $12,000,000 to just over $15,100,000, and the founders used the figure to open discussions with a private equity buyer.
During diligence the buyer split the number apart. An acquisition completed in month three contributed $2,300,000 of the increase, and a price rise applied across the catalogue accounted for a further $600,000. Underlying organic volume growth was closer to 2%, which was roughly in line with the wider outdoor market.
In this fictional case the deal still went ahead, but at a lower multiple than Marlow had expected. The lesson the founders drew was that they should have been reporting organic and acquired growth separately in their own board pack long before an outside buyer did it for them.
Watch out
Common mistakes.
- Comparing a quarter against the immediately preceding quarter in a seasonal business, which produces growth figures that reflect the calendar rather than performance.
- Quoting total sales growth without separating out acquisitions, price rises and new locations from genuine underlying demand.
- Celebrating strong sales growth without checking whether gross margin and cash collection moved in the same direction.
Questions
People also ask.
What counts as good sales growth?
It depends entirely on the sector; low single digits can be strong for a mature utility while an early stage software company might target 50% or more.
Should sales growth use gross or net sales?
Net sales, after returns and discounts, gives the more honest picture, and the same basis must be used for both periods being compared.
How does inflation affect the figure?
Reported growth includes price inflation, so in high inflation periods analysts often also calculate real growth by adjusting both periods to comparable prices.
