1 Point Per Dollar or 100 Points Per Dollar?

When designing a loyalty program, have you ever wondered whether you should give customers 1 point for each dollar they spend and require 100 points for a free reward, or if it’s better to grant 10 points per dollar and require 1000 points for the reward? On the surface, these two setups require the exact same effort from consumers and should make no difference to the effectiveness of your program. But an article by Professor Rajesh Bagchi and graduate student Xingbo Li published in the Journal of Consumer Research says it’s not quite as straightforward as you may think. Which option is better depends on whether you have a straightforward single point structure or a mixed structure, and whether your focus is on encouraging low spenders or rewarding heavy buyers.

Context

The authors conducted two lab experiments. The first experiment was based on a grocery store loyalty program and involved 246 undergraduate students. Various aspects of the loyalty program were manipulated, and the respondents reported how likely they would recommend the program to others and whether the program would increase their loyalty toward the store. In the second experiment, 375 student and non-student respondents made simulated purchases given a restaurant loyalty program. At the end of the simulation, they also reported their recommendation likelihood and perceived loyalty effect.

Main Findings

  • Point ratio (low: 1 point/dollar vs. high: 10 points/dollar) has opposite effects depending on whether the program has a clear point structure (i.e., a clear point ratio is applied across the board) or a mixed structure (e.g., point ratio may vary across product categories or across time).
  • Under a clear point structure, a high point ratio (10 points/dollar) leads to similar reactions from consumers who are far from the reward threshold (e.g., has earned 20 out of 100 points required) as consumers who are close to the reward threshold (e.g., has earned 80 out of 100). A low point ratio, on the other hand, creates much more positive reaction among consumers who are close than among consumers who are far.
  • Under a mixed point structure, the opposite is true. A high point ratio leads to much more favorable reactions among consumers who are close to the reward threshold than those who are still far. A low point ratio, in the meantime, does not make a significant difference.

What Does This All Mean to Practice?

To translate these findings to practice, we can first consider the practical equivalence for being near vs. far from the reward threshold. For low spenders at a company, they are likely to spend more time being pretty far from the reward threshold. For existing heavy buyers, in contrast, they earn points easily and probably spend a good amount of their time being very close to the reward threshold. Based on this translation, the following chart shows how to determine the best strategy to use:

Program Goal
Encouraging Low SpendersRewarding Best Customers
Point StructureSimple
e.g., Best Buy Reward Zone, where you get 1 point every dollar spent
High point ratioLow point ratio
Mixed
e.g., Priority Club, where how many points are issued depends on the chain that you stayed at
Low point ratioHigh point ratio

Do these findings make sense to you? How has your experience been dealing with point ratio? I would love to hear your thoughts!

    Thanks for the this article, very interesting. I´m from south america. I recent in charge of loyalty area in a local bank, and we have the system 1 dollar= 1 point, however we have promotion to earn more points (i.e. if you paid your children´s school, you have 2 points for a dollar). or if you maintain a average of consume with your credit card in a period, i bring you more point, or if you have a upscale credit ard, like black MC. regards.
