What is product cannibalization? How CPG brands detect, measure, and prevent it

In retail, a newly released product can cause a loss of sales for other items within a company’s product portfolio. This is known as product cannibalization, and occurs when the demand for the new product detracts from the demand for existing products, causing a marked loss of revenue for the items that preceded it.

Sometimes, product cannibalization is an unintended effect, and a company will make an effort to recover the lost sales across its product portfolio. Other times, product cannibalization can be part of an intentional strategy to lead with a new product, attract greater audiences, and grow bottom line sales with a new, more premium-priced item.

In CPG, product cannibalization is a common phenomenon that can be studied to derive insights about new product innovation and consumer shopping behavior, and can be used to guide a retail strategy.

Product cannibalization is a bit different from regular competition, because it occurs within a company’s own portfolio of products. It is when a company’s new product effectively “steals” sales from its other products – without growing the category or the company’s net revenue.

What is product cannibalization in retail?

CPG brands compete against one another for sales every day. Companies are no stranger to retail’s competitive landscape, and are always devising and reworking strategies to maintain and increase their market share.

Product cannibalization is a bit different from regular competition, because it occurs within a company’s own portfolio of products. It is when a company’s new product effectively “steals” sales from its other products – without growing the category or the company’s net revenue. Instead of attracting new customers or driving multi-SKU purchases, the new product simply “cannibalizes” – or eats the sales – of their other products.

For the supplier, this can cause compounding, excess inventory of its other products that may lead to a loss of revenue, and affect relationships with retail buyers.

Retailers are not always keen on the phenomenon of product cannibalization, as they lose sales on the neglected products, just as the brands do. The excess stock can also take up space on the shelves or back rooms – valuable real estate that may be better served by another brand’s goods.

However, savvy brands are utilizing product cannibalization to guide their sales strategy, rethink product innovation, and prove incrementality (the ability to grow a category through sales of different products) to retailers.

Potential reasons for product cannibalization

Product cannibalization can occur for a number of different reasons, depending on the product’s pricing, the type of product, or how the category is evolving. As mentioned above, the effect of product cannibalization can be an unintended result of taking new products to market – or a strategic move by a supplier to alter their product mix over time. 

Pricing

If a supplier releases a lower-priced item that is similar to their other items, consumers may choose to only buy that product. In order to maintain sales volume of the higher-priced item, the company will need to communicate its differentiated value. By clearly communicating the features and benefits of differently priced items, brands can attract new audiences with diverse values – and increase top-line growth rather than lose sales to their cheaper SKUs.

Product cannibalization can also occur when an item is discounted. Discounting products can be considered a method of intentional cannibalization, in an effort to sell through a product more quickly than others. In any case, suppliers will want to consider how promotional pricing will affect sales for other products within their assortment.

Product Mix

Leading CPG brands meet consumers’ demand for variety by maintaining a wide assortment of styles, flavors, product types and pack sizes within their product mix. They are able to maintain sales across the different items, and avoid product cannibalization by distinctly communicating the value of each item.

Introducing a new type of product can result in cannibalization of sales if it comes across as more valuable or useful than existing products. For example, a new, all-in-one cleaning solution can displace a brand’s other cleaning products. Or shoppers may reach for a new food or beverage product with added nutritional or health benefits, instead of a brand’s other products that are without them.

Sometimes, product cannibalization can occur when the new product is simply more flavorful or exciting.

New product development is an important process that CPG organizations invest in to meet the emerging needs of consumers, and can be leveraged to maintain and grow market share through the introduction of trending and all-together new product concepts. When done successfully, brands can attract new consumers, in addition to their loyalists and grow their product mix with success. However, new product development can also result in product cannibalization, triggering displacement of existing items by making them seem redundant.

What product cannibalization looks like in retail

Unintentional product cannibalization 

Say that a grocery wine brand sells bottles of wine priced over $20, and releases a red blend with a special label to draw in a new customer base – priced under $20. The wine brand faces product cannibalization when new customers and brand loyalists alike purchase the new red blend instead of the other bottles. This becomes a bigger cost issue if the customers make the same repeat purchases, because the brand’s perceived value will begin to align with the lower priced item. It will prove challenging to regain the sales volume of the original products, and their production costs can amount to lost revenue.

A snack brand experienced product cannibalization when it released a line of chips that are crispier because they are cooked in a new oil, and more irresistible because of new and exciting flavor additives. The product was intended to serve as a line extension, but due to customer demand it has effectively cannibalized sales of the other products. While the new products generate promising profits, the company did not anticipate loss of sales for their other goods and is struggling to resolve them.

Intentional product cannibalization

Apple is a classic example of a company that plans for product cannibalization and leverages it to attract and retain new customers. For starters, the iPhone is considered to have cannibalized the iPod (and smartphones as a whole are considered to have cannibalized the digital camera). Today, new generation iPhones cannibalize former models by including newer features for a relatively low price increase.

The iPad also cannibalizes some sales from Mac computers, but the company plans and allows for this considering that it keeps customers in the Apple product ecosystem.

If a CPG food company conducts market research, and finds that its target market prefers options with added health benefits, the company may release a healthier line extension, and build awareness around it with a national marketing campaign and attractive design elements that call out the new features. They do not advertise for the original, more processed and sugary line and intentionally allow the new products to cannibalize its sales. Since the brand planned thoroughly for this, they did not overproduce the former products and enjoy a healthy new revenue increase overall.

Calculating product cannibalization

There is a method for calculating a cannibalization rate to better track its impact within a business. By calculating the cannibalization rate for different products after a new product release, a company can make better decisions about how to address the issue.

The formula for a brand to identify a product cannibalization rate is:

Product cannibalization rate = (number of sales lost on existing product / number of sales of a new product) x 100

With number of sales lost on an existing product = Last year’s units sold – this year’s units sold (ex. 2000-1000=1000)

And sales of a new product being the number of units sold of the new product SKU in the same period (ex. 2500)

For example, (1000/2500) x 100 = 40% cannibalization rate

When CPG brands release new products, some degree of product cannibalization can be expected, with the trade off being that the new product begins to gain traction in the market. By using the cannibalization rate formula, companies can identify which products are losing the most sales and strategize how to recover the lost revenue.

Crisp’s retail data platform provides year-over-year sales comparisons at the SKU, store, and DC level – the necessary inputs to calculate cannibalization rates for any given product. And with daily data refreshes, teams can monitor cannibalization trends within days of a new product launch, not weeks.

How AI is changing cannibalization detection

Traditionally, brands spotted product cannibalization by manually comparing sales reports weeks or months after a launch – often too late to course-correct. AI is changing this.

AI Agents built on real-time retail data can monitor an entire product portfolio simultaneously and flag cannibalization patterns as they emerge. Rather than waiting for a quarterly review, brands can ask direct questions about how a new SKU is affecting velocity of existing products – and get answers grounded in current POS and inventory data, down to the store level.

AI can also separate real cannibalization from other variables. A dip in sales for an existing product might look like cannibalization, but could actually be caused by a regional out-of-stock, a competitor’s promotion, or a seasonal shift. AI Agents can cross-reference multiple data signals – inventory levels, promotional calendars, distribution changes – to determine whether the sales decline is truly driven by the new product.

This matters because misdiagnosing cannibalization leads to the wrong response. If a brand pulls back on a successful new product because it appears to be cannibalizing existing SKUs – when the real issue is a distribution gap – they lose twice.

Conclusion

A company can avoid product cannibalization by innovating and going to market with products that are complementary to – and not competitive with – other products in their assortment. When successful, new products attract new consumers to a brand without affecting the sales velocity of other items, effectively generating a new revenue stream that helps the company grow.

It happens that sometimes, product cannibalization is necessary to shift the product offerings as a whole and evolve the company’s positioning.

By using data at every stage of new product development – through to launch and after – companies can anticipate and plan for product cannibalization. AI makes this faster and more precise: rather than waiting for monthly reports to surface a problem, brands can monitor their entire portfolio in real time and act on cannibalization signals as they appear. Having full visibility over product performance, at the SKU and store level, turns cannibalization from a risk into something you can measure, manage, and strategize around. Reach out to learn more.
