Definition and Formula
The loyalty breakage rate is a financial and engagement metric that measures the percentage of all issued loyalty points (or their value) that expire.
There are two views of this KPI:
- Finance/Accounting perspective: Points represent a liability on the company's balance sheet. When points expire, that liability is "broken" and is recognized directly as revenue (or a reduction in liability)
- Loyalty/Marketing perspective: A high breakage rate is a critical failure. It signifies that the program is not engaging, the rewards are unattainable or undesirable, or the communication is poor.
The goal is not to achieve 0% breakage but to find an optimal rate that signals strong engagement while remaining financially sustainable (not giving away large discounts).
There are two primary methods for calculating breakage, one based on a specific period and the other based on a set of customers.
A. Periodic Breakage Rate (Operational KPI)
This is the most common way to track breakage as an ongoing operational metric. It measures what percentage of all points removed from circulation during a period was due to expiration versus redemption.
Periodic Breakage Rate = Value of Points Expired in Period \ (Value of Points Redeemed in Period + Value of Points Expired in Period)
B. Customer Set Breakage Rate (True Liability Model)
This is the financial definition used for accounting; it tracks a specific batch of issued points from creation to their final expiration date.
Customer Set Breakage Rate = Total Points Expired (from Customer Set) / (Total Points Issued (to Customer Set)
Do note that redemption rate is the inverse of loyalty breakage rate. For any pool of points that has finished its life (meaning it has either been redeemed or it has expired), the relationship is:
Periodic Redemption Rate + Breakage Rate = 100%
Do note that there are different formulas that can be used for redemption rate but for consistency will use the periodic redemption rate.
