NPS Scores Don't Predict Defection: New Research Challenges Marketing Dogma
Research from Australian firm 5D reveals NPS scores fail to predict defection. For APAC CMOs, the findings expose a measurement gap that's reshaping retention strategy.
Your marketing team has spent years building the perfect customer profile. Age range, income bracket, location, lifestyle. The assumption is simple: find people who look like your best customers and turn them into new ones.
New research says that assumption is broken. And for services businesses, the consequences are serious.
Australian research consultancy 5D analyzed more than 2,000 real customer decision journeys across services categories. Their finding is blunt: the single biggest predictor of how people choose a services brand is no longer who they are. It is how many times they have made that type of purchase before.
The Gap That Didn't Exist Five Years Ago
When someone buys a service for the first time, traditional marketing still works. 66% of first-time buyers already had the brand they eventually chose on their consideration list before they even started looking. Brand awareness and reputation matter for newcomers.
Experienced buyers behave differently. Among people who had bought in that category before, only 50% chose a brand they had pre-planned to consider. That is a 16-point gap, and it barely existed five years ago.
Roughly a third of experienced buyers chose a brand they had never even thought about before the decision moment. They arrived at the decision open. Something during the actual buying process changed their mind. That is a massive opportunity for competitors and a massive risk for incumbents.
Your NPS Score Is Lying to You
Here is the uncomfortable part: most brands cannot tell which of their customers are genuinely loyal and which are just staying put for now.
Mission Media"Experienced buyers are not loyal by default," says Lyndall Spooner, Founder and CEO of 5D. "They split into two groups: those who are genuinely committed to a brand because of the quality of the relationship, and those who are simply responding to the best offer at the time. The second group might deliver solid net promoter scores, but they will leave the moment a better deal appears. Brands need to know which customers they actually have."
This is a problem because net promoter score (a survey-based measure of how likely customers are to recommend you) is the primary loyalty metric at most organizations. Academic research shows NPS changes have almost no correlation with how customers actually allocate their spending. You can have a customer who scores you nine out of ten and still walks out the door for a rival offering a slightly better package next month.
PwC's 2025 Customer Experience Survey adds more trouble. Nine in ten executives believe customer loyalty has grown. Only four in ten consumers agree. Executives are systematically overconfident about the loyalty they have earned.

The APAC Situation Is Worse Than Average
For marketing leaders in Asia Pacific, this research lands with particular weight. Forrester's 2025 Global CX Index measured consumer perceptions of 469 brands across 12 industries globally. Globally, 21% of brands declined in customer experience quality while only 6% improved. In APAC specifically, 37% of brands fell and just 5% rose.
This is happening while 59% of APAC businesses say they are increasing investment in customer experience management. Investment is rising, but the actual experiences are getting worse. The money is going somewhere, just not into places customers notice.
The paradox points to a measurement and execution gap. Brands are investing in experience, but they are measuring the wrong things and executing against the wrong priorities.
The First 12 Months Are Everything
There is a window. Brands that understand this research are acting on it.
Mission Media"Every brand has a moment, usually during the first 12 months a customer is with them, where they can either deepen the relationship or lose the customer to the next offer," Spooner says. "Technology has compressed that window. Brands that invest in better products, better service and better tools for their customers are the ones converting first-time buyers into long-term loyalists."
The economic case for closing that window is clear. Customer acquisition costs have risen 222% over the past eight years. Yet 44% of companies still direct the majority of their marketing budget toward acquiring new customers, while only 18% focus primarily on keeping the ones they have. Emotionally connected customers deliver up to 306% higher lifetime value than customers who are merely satisfied.
The math is not close. But the habits are hard to change because acquisition spending is visible, attributable, and comes with dashboards. Post-sale relationship investment is slower and harder to measure, which is exactly why most organizations underinvest in it.
The 5D research is a signal that this trade-off is becoming unsustainable. Demographic targeting gives every competitor access to the same audiences. Post-sale experience is the one thing competitors cannot copy overnight.
The question for marketing leaders is not whether to shift some focus from acquisition to retention. It is whether the organization can actually tell the difference between a customer who would never leave and one who is already browsing alternatives.
