A 2025 J.D. Power survey of 90,000 retail banking customers across 18 countries found that digital banks outperformed traditional banks on customer satisfaction in every metric measured: ease of use, fee transparency, speed of service, problem resolution, and product value. The average net promoter score (NPS) for digital banks was 52, compared with 18 for traditional banks. These numbers explain why an increasing share of consumers, particularly those under 40, are choosing digital banks as their primary financial institutions.
What Consumers Value Most
According to J.D. Power’s data, the single most important factor in banking choice for consumers under 40 is mobile app quality. Among consumers aged 18 to 30, 78% said app quality was their top consideration, ahead of interest rates, branch proximity, or brand reputation. For consumers aged 30 to 40, app quality was the top factor for 62%. The data reflects a generation that experiences banking primarily through their phones and evaluates providers accordingly.
Fee transparency ranked second across all age groups. According to a McKinsey study on banking choice factors, traditional banks generate an average of $280 per year in fee revenue per retail customer, compared with $35 at digital banks. The difference comes from overdraft fees, maintenance fees, ATM fees, and transaction fees that digital banks have largely eliminated. Fintech platforms are reducing financial transaction costs by up to 80%, and consumers are choosing providers that pass those savings along.
The Switching Trend by Demographics
The shift toward digital banks is most pronounced among younger consumers but is spreading across age groups. According to Statista’s data on digital bank adoption by age, 42% of consumers aged 18 to 25 use a digital bank as their primary institution, compared with 28% of those aged 25 to 35, 15% of those aged 35 to 50, and 6% of those over 50.
The most common trigger for switching is a negative experience at a traditional bank. According to a 2025 Accenture study on bank switching behavior, the top three reasons customers left traditional banks for digital alternatives were excessive fees (cited by 45% of switchers), poor mobile app experience (38%), and slow service (32%). 60% of consumers now prefer digital financial services, and each negative experience at a traditional bank makes the switch more likely.
Word-of-mouth referrals are the primary acquisition channel for digital banks. Neobanks like Monzo and Cash App grew initially through referral programs where existing users invited friends. The social dynamics of banking choice mean that once a critical mass of a consumer’s social circle uses a digital bank, the pressure to switch increases significantly.
The Products Driving Adoption
Several specific products have been particularly effective at attracting consumers to digital banks. High-yield savings accounts are one. Digital banks offer interest rates that are often 5 to 10 times higher than what traditional banks pay, because their lower cost structures allow them to return more to depositors. According to a BCG study on digital bank product adoption, high-yield savings was the most common entry product, cited by 35% of digital bank customers as the feature that initially attracted them.
Fee-free international spending is another key product. Revolut and Wise both offer near-interbank exchange rates for international purchases and ATM withdrawals, saving frequent travelers hundreds of dollars per year compared with traditional bank foreign transaction fees. Digital wallet usage has reached more than 4 billion users worldwide, and international functionality is an increasingly important feature of digital wallets and banking apps.
Early wage access, popularized by Chime and Dave in the US, allows customers to receive their paychecks up to two days before the traditional payday. This feature has been particularly popular among hourly workers and customers living paycheck to paycheck.
What Traditional Banks Are Doing in Response
Traditional banks are responding with significant investments in digital experience. Bank of America’s mobile app now serves more than 50 million digital users. JPMorgan’s digital platforms serve more than 60 million active customers. Both banks have invested billions in app quality, and their satisfaction scores have improved as a result. 75% of banks now collaborate with fintech startups, often specifically to improve digital features that compete with neobank offerings.
However, the structural challenge remains. Traditional banks cannot easily eliminate the fees that fund their branch networks and legacy operations. Digital banking customers are expected to exceed 3.6 billion by 2028, and the institutions that capture the most growth will be those with the lowest cost structures and the best digital experiences.
J.D. Power’s NPS gap of 52 versus 18 between digital and traditional banks is widening, not narrowing. Until traditional banks can match the fee structures and digital experience quality of neobanks, the customer migration toward digital providers will continue to accelerate.
