Nubank surpasses 112 million customers and becomes the largest private financial institution in Brazil. 85% of the customer base is active on a monthly basis!

Nubank is now the largest private financial institution in Brazil by number of customers, according to the latest data released by the Brazilian Central Bank for the year 2025. The company surpasses 112 million customers, about 61% of the country’s adult population.

Since 2022, the year the company entered the top five in the ranking, Nu has been the fastest-growing institution, climbing one position each year. In addition to expanding its customer base, customer service excellence was maintained, with Nu once again among the lowest complaint rates in the Central Bank ranking.

The continued growth in its customer base was accompanied by record engagement, the result of a strategy to deepen customer relationships and increase the use of Nubank products and services, said Livia Chanes, CEO of Nubank Brazil, on a recent episode of Nu Videocast: 85% of the customer base in Brazil remained active monthly, and average revenue per active customer (ARPAC) reached its highest historical level in the third quarter of 2025.

“More than growing in numbers, our focus is to have a meaningful presence in people’s financial lives,” said Livia. “Our base of more than 112 million customers is the result of continuous work to offer products that make sense in everyday life, supported by human customer service and technology that removes daily complexity.”

With a customer-centered strategy focused on long-term relationships, in less than a decade, Nu has helped its customers save more than R$111 billion in fees. In 2025 alone, customers saved R$158.8 million due to partnership discounts. In addition, more than 6 million customers have renegotiated their debts.

This expansion at scale and the intensification of activity are accompanied by strong quality indicators. Besides maintaining one of the lowest complaint rates in the Central Bank ranking, Nu won the Reclame AQUI Award for the ninth consecutive year, reinforcing its commitment to customer service excellence.
