Repurchase Rate is the single most important indicator of customer loyalty. We calculate repurchase rate by dividing our database into two time periods. We identify all customers who purchased during, say, 2007. Then, we calculate the percentage of 2007 customers who purchased again during 2008.
In Multichannel Forensics, we divide the annual repurchase rate into three categories.
- Retention Mode: Annual Repurchase Rate > 60%.
- Hybrid Mode: Annual Repurchase Rate between 40% and 60%.
- Acquisition Mode: Annual Repurchase Rate less than 40%.
When I worked at Eddie Bauer, we were largely in Hybrid Mode ... we retained between 40% and 60% of our customers, year-over-year. Hybrid Mode is the most enjoyable business model to work in, because you have so many levers to improve business success. At Nordstrom, you weren't going to improve the retention rate from 76% to 91%, it simply wasn't mathematically possible. But in Hybrid Mode, you can make a difference!
When I worked at Eddie Bauer, we had a Home division. That division was in Acquisition Mode, with an annual repurchase rate under 40%. The only way this business was going to grow was by acquiring new customers at a faster and more profitable rate than last year, period. You simply cannot get a customer who just purchased a couch to buy another couch! During my time at Eddie Bauer, we were only able to get the Home division close to break-even once --- and during that year, we did that by renting the entire Pottery Barn list, over and over and over. We mailed more Pottery Barn names than we mailed Eddie Bauer names ... at least that's the way I remember it!
Acquisition Mode is the least understood by direct marketers, and it is a scenario that is about to become a really big deal to online marketers.
You see, so many of the folks working in the online channel manage an "Acquisition Mode" business. As mentioned earlier, these channels/businesses succeed when new customers are increased at a profitable rate, year-over-year. Thanks to Google and offline cannibalization, this was easy to do, year-after-year. A generation of online marketers grew their business without the hand-to-hand combat other channel leaders had to deal with. In 2009, the easy flow of new customers, courtesy of Google or offline channels, is ending.
This is where things get really interesting, folks. If your online channel is in Acquisition Mode, and an easy flow of new customers from other channels or Google is drying up, you have challenges in front of you. So be sure to measure your annual retention rate right now --- it is so easy to do!! Understand the dynamics of your business, and begin to plan for the consequences of your business model.
