Loyal or Stuck: A Test for Customer Retention

You can open your customer spreadsheet and see a renewal, a repeat order, or a quiet account that has not left. That presence can be habit, convenience, or the absence of alternatives. Run the stuck-versus-staying test on the list: mark who would leave if switching got easy, mark who would stay because of the work, then put retention budget on the second list.

Stuck customers hide in your revenue

CSI's 2026 study surveyed 1,000 U.S. account holders aged 21 to 65, and the survey ran from June 29 to July 22, 2026. 51% of bank and credit union account holders said their continued banking relationship was driven by the difficulty of switching. 40% had thought about changing institutions after a major life event in which they felt unsupported.

A stuck customer can pay on time, renew quietly, and never complain. A staying customer may complain, ask for help, and still come back. The difference is not visible on the revenue line.

Repeat purchases driven by habit, convenience, or absence of alternatives instead of commitment are called spurious loyalty in Dick and Basu's 1994 loyalty matrix. The hassle of switching can keep a customer in place even when the relationship is weak.

The test separates presence from preference

Do the test in four steps.

• List your active customers by how much they are worth and how recently they bought, then add a note on why each one came back. Build a simple spreadsheet with name, last purchase, total value, and a reason.
• Ask each customer one question: if switching got easy, would you stay? Mark each account stuck or staying.
• Look for the work signal in the notes, such as a praised outcome, a tolerated mistake, or a request for more. Keep only the marks backed by evidence, not just repeat purchases.
• Put the retention budget on the staying list, not on the whole base. Write a monthly plan that names the customers who get the extra effort.

The common mistake is to treat repeat purchase as proof. A customer can buy again because the product is built into their routine, the contract is annoying to cancel, or the alternative is unclear. If you cannot point to the work they value, move the account to the stuck column.

The budget should follow the staying list

Staying customers are worth more because they reduce the need to replace them. Acquiring a new customer can cost up to five times as much as keeping an existing customer. The staying list deserves the first budget line.

In Capgemini's Loyalty Deciphered research across 9,213 consumers, consumers with high emotional engagement were 82% likely to always buy from their loyal brand, versus 38% for low-engagement consumers.

Among the CSI account holders, 83% said a financial institution that helped them navigate a major life event would earn stronger loyalty. The budget should buy those moments.

Send a check-in before a known renewal date. Offer a short review of what the customer has saved, avoided, or gained. Ask what would make the next year easier. Then track whether the staying list grows, shrinks, or stays flat. If it stays flat, the effort is aimed at the wrong accounts. If it grows, you are paying for customers who stay because of the work.

The test only works if you repeat it

Run the test quarterly, not just when revenue dips. A customer who is staying this quarter can become stuck next quarter if your service gets thinner or a competitor makes switching easier. Keep the spreadsheet current, re-ask the one question, and compare the staying list against last quarter.

If every account is marked staying, your notes are too vague. If every account is marked stuck, your work may not be visible enough. The useful result is a smaller list of customers who clearly value the work, and a larger list that needs a different kind of attention.
