Loyalty Program Margin Check: Three Numbers to Run First

A loyalty program is a discount until it is not

You are weighing a loyalty program for your small business. The upside is real: people in restaurant loyalty programs dine out 20 percent more often and spend 20 percent more on each visit than non-members, while enrolled customers show 70 percent higher lifetime value. In a Deloitte 2025 survey, 72 percent of members said the program made them more inclined to buy from their favorite brand, and 56 percent said it raised their spending. The cost is also real. A loyalty program is a discount program when its most attractive perk is just a coupon.

Many owners start with the perk and work backward. The safer order is to run the loyalty program math first. You need three numbers: earn rate, redemption threshold, and welcome window. The math is simple. Write down your average sale. Multiply it by your margin to see how much each sale contributes before the reward. Then compare the value of one point, the value of the first reward, and the value of the welcome offer to that number. Values close to that number mean the program is eating the sale. Do this before you pick a perk.

The three numbers are the real cost

Use this checklist as the first draft of your rewards program cost. Each item takes a minute, and each points to a design choice that can change margin.

• Earn rate: Set the base earn rate from average order value and desired margin impact before normalizing across currencies. Then compare the value of one point to your margin. A point value close to your margin means every redemption eats the sale.
• Redemption threshold: Keep the first reward within easy reach; waiting six months for the first redemption asks for a long-term commitment before the relationship exists. For a local business, that is too long.
• Welcome window: Pair sign-up with a welcome incentive, an early success, and a reason to return before interest cools.

Fix any failing number before building the rest.

Fatburger, a made-to-order burger chain owned by OHG Brands, introduced Fatburger Rewards as its first loyalty program. The program gives one point per dollar of eligible spend and redeems 75 points for a $5 discount. Those are clear numbers, but they still need to be checked against the chain's average sale and margin.

Points programs can make budgets more predictable because the brand pays only when a customer uses points, and unused points that expire keep their value with the company. That does not remove the need for margin checks. It moves the cost from a fixed discount to a variable one.

The welcome window is the first test

The welcome window is the time limit on the first offer. It sets how long the first cost lasts and how quickly the customer must return. A welcome offer is the first proof that the program is worth joining. A weak offer may get a sign-up and no return. A strong but unprofitable offer pays for a one-time visit.

Fatburger Rewards gives new sign-ups $5 off a $20-or-more purchase, valid for 30 days at participating locations. Fatburger said the program will also feature mobile-exclusive deals, time-bound promotions, extra reward opportunities, and member-only benefits. Those extras can make the program feel like more than a coupon, but they still need to pass the same margin test.

Run the check before you build, and after you change it

Do not treat the three-number check as a one-time task. Run it before you build the program. Run it again after you change the earn rate, raise the redemption threshold, or shorten the welcome window. Each change is a pricing decision, and pricing decisions belong in the margin.

Failing numbers usually call for a smaller point value, a higher redemption threshold, or a smaller welcome offer. Check the math before you launch. A reward your margin can carry is the only one worth promising.
