The Bottom Line From The Numbers Guy

In this case at least, offering unlimited monthly passes didn’t lead to customers abusing the program. With an average of under two visits a month, customers certainly aren’t “over using” their passes. The moderate return rate of monthly pass holders has resulted in a relatively high dollar per vehicle average of close to $24 for monthly pass customers. These customers apparently don’t mind paying a premium for their monthly passes, since only about 6% of them dropped out of the program. The rate of new customers entering the program was about 1.7 times higher than this dropout rate.

Apparently, customers value the benefits of monthly passes enough to be willing to pay more per visit. What are those benefits? First, there’s the sense of control that comes from knowing they can get their vehicles washed whenever they want. Second, there’s the freedom of never having to worry about having enough money on hand when they visit the wash. And third, there’s the convenience of not having to remember to renew their pass plan every month.
