Building Your Sliding Price Scale

Use this resource to help you build your sliding price scale.

Your sliding price scale should be based on the results of your survey. The “sliding” part of the scale should include percent discounts. It will be your responsibility to justify how you set up your percent discounts by reasoning about your survey results. There is no right answer, but your justification should make sense and be supported by data.

For example, you might argue that 5-day-old bananas will be discounted 40% in your sliding price scale, because:

  • 20% of customers would choose these bananas without a discount, and
  • 50% more would be convinced to buy these bananas with a 40% discount.

This means 70% of customers would be likely to choose the 5-day-old bananas if you offered a 40% discount.

What Should be Included in a Sliding Price Scale:

Your sliding price scale should include

  1. Descriptions of how and when foods are discounted.
  2. The percent the foods are discounted.
  3. The price after each discount.
  4. A justification for how you designed your sliding price scale.
