Case study: how a loyalty program quietly ate the profit

A coffee-shop chain grows, customers pile in, but the bank balance shrinks. Simple math showing how growth can push a business into the red.

Imagine: you own a small but popular coffee-shop chain. Three locations of your own, a couple more franchised. Stable income, taxes paid, staff content. The bank offers a loan at a good rate — it would be a sin not to think about expanding.

To attract more customers you introduce a loyalty program: every sixth cup of coffee is free. You open two more locations, customers keep coming, you can barely print the vouchers fast enough. Yet somehow there's less and less money in the account. How come?

The math BEFORE

  • Revenue per location: 100,000
  • Rent and utilities: 15,000
  • Marketing: 10,000
  • Salaries: 40,000
  • Supplies and equipment: 30,000
  • Profit: +5,000

The math AFTER

  • Revenue per location: 100,000
  • Rent and utilities: 15,000
  • Marketing: 10,000
  • Free coffee (≈5% of revenue): 5,000
  • Loan payments: 2,500
  • Salaries (a manager is needed): 45,000
  • Supplies and equipment: 30,000
  • Profit: −7,500

An extra manager, a loyalty program at 5% of revenue and the loan payments together «slightly» adjusted the profit. And with every new customer the business started losing money instead of earning it.

The scale of the problem depends on how quickly you spot it. It's easy to fall into a vicious circle: less revenue → less money for marketing → fewer customers → even less revenue. Estimating the cost of a «tasty» loyalty program in advance is vital.
