What it means
In business, companies often introduce new items to capture market share, reach different audiences, or block competitors. However, if your new product is too similar to what you already sell, loyal customers will simply switch over.
This means you are paying to produce and market a new item while losing the steady sales of the old one. For non-finance managers, understanding this concept is vital when approving new product budgets.
You must look beyond gross sales forecasts and calculate net gains. If a new launch generates ten thousand pounds in revenue but causes an eight thousand pound drop in your flagship product sales, your actual net gain is only two thousand pounds.
In practice, companies weigh the risks of internal competition carefully. Sometimes, cannibalisation is a deliberate strategy.
If you do not launch the new product to steal your own sales, a competitor will do it for you. The key is ensuring that the long-term strategic benefit outweighs the short-term margin dip.
In practice
Real-world examples.
Example
A smartphone maker launches an advanced model priced at eight hundred pounds. Sales of their previous six hundred pound model drop sharply as buyers upgrade to the new version, resulting in lower total profit margins.
Example
A local bakery introduces artisan sourdough loaves. Regular customers stop buying their standard white bread, shifting their spend to the new sourdough, leaving total daily revenue almost completely unchanged.
Example
A software firm releases a cheaper mobile app version of their desktop software. Many corporate clients downgrade their expensive desktop subscriptions to save money, reducing the company's average revenue per user.
Think of it
“Imagine you own a popular local burger van and decide to open a second burger van right next door. You might attract some new foot traffic, but many of your regular customers will simply queue at the new van instead, meaning you just split your existing crowd.
Formula
Calculation
Net Revenue Gain = New Product Revenue - Lost Revenue from Existing Products
Example:
New Product Revenue = 50,000 pounds
Lost Revenue from Existing Products = 30,000 pounds
Net Revenue Gain = 50,000 - 30,000 = 20,000 poundsCase study
Seen in the real world.
GreenLeaf, a mid-sized beverage company, sold a popular organic juice in glass bottles for three pounds fifty pence. To appeal to eco-conscious shoppers, they launched the same juice in lightweight cartons for two pounds fifty pence. GreenLeaf projected total sales would jump by one hundred thousand pounds.
When the cartons hit supermarket shelves, sales surged. However, financial analysis at the end of the quarter revealed a hidden problem. Shoppers who previously bought the glass bottles simply switched to the cheaper cartons. Glass bottle sales fell by eighty thousand pounds, while carton sales reached one hundred thousand pounds.
Because the cartons had lower profit margins due to higher packaging production setup costs, GreenLeaf's overall profit actually decreased. The marketing team celebrated the top-line sales growth, but the finance department noted that the company had effectively paid to shift its own customers to a less profitable format. GreenLeaf learned that understanding customer switching behaviour is just as important as predicting total market demand.
Watch out
Common mistakes.
- Assuming all new product sales are entirely new revenue without checking if existing sales dropped.
- Failing to account for differences in profit margins between the old and new products.
- Ignoring the risk of competitors cannibalising your market share if you refuse to innovate.
Questions
People also ask.
Is cannibalisation always a bad thing?
No. It can be a defensive strategy to stay ahead of competitors or to transition customers to a better, more modern product line before rivals do.
How can I measure it accurately?
Track sales trends of your existing products immediately following a new launch, and use customer surveys to find out if buyers switched from your older items.
Can services suffer from this issue as well as physical products?
Yes. If a consultancy firm launches a low-cost subscription advisory service, existing clients paying for premium one-to-one consulting might downgrade.
