Revenue Model & Pricing
Nubank earns revenue mainly from interest on credit card balances, personal loans, payroll and secured loans, and from yield on the securities it buys with customer deposits. Fee and commission income adds interchange on card spending, late fees, and commissions from insurance, investments and marketplace sales. The model depends on acquiring customers cheaply (largely by word of mouth), serving them through an app at a low monthly cost, and then raising average revenue per active customer (ARPAC, about $15 a month in Q4 2025) by cross-selling credit, savings, investment and insurance products.

How Nubank Makes Money: FAQ
How does Nu Holdings make money?
Mainly interest income on credit cards, personal, payroll and secured loans, plus yield on securities funded by deposits. Fee and commission income from interchange, late fees, insurance, investments and marketplace sales makes up the rest. FY2025 IFRS revenue was $15.77 billion.
What is Nubank's cost to serve?
Nubank reported a monthly cost to serve of under $1 per active customer in Q4 2025, helped by having no branches and heavy use of app self-service.
What is ARPAC and how high is it?
ARPAC is average monthly revenue per active customer. Nubank said it reached about $15 in Q4 2025, driven by cross-selling credit, savings and other products.
How does Nubank acquire customers?
Mostly through referrals and word of mouth, which keeps acquisition costs low compared with incumbent banks that rely on branches and advertising.
What are the primary revenue streams that drive Nubank's business model?
Nubank generates revenue through two primary engines: net interest income (NII) from its expanding credit card revolving and personal loan portfolios, and fee and commission income, which includes card interchange fees paid by merchants on every credit/debit purchase, insurance distribution commissions, and wealth management fees.
What is Nubank's structural "cost to serve" advantage over legacy brick-and-mortar banks?
Nubank operates with a monthly average cost to serve of less than $0.90 per active customer, compared to $10 to $20+ for legacy banks burdened with expensive branch networks, security guards, and legacy mainframe systems. This 90%+ cost advantage allows Nubank to offer free products and competitive interest rates while generating record profit margins.
How does Average Revenue per Active Customer (ARPAC) expand over time?
As customers mature on the platform and adopt multiple products (using Nubank as their primary checking account, savings account, credit card, and loan provider), their monthly ARPAC climbs from under $3–$4 in early cohorts to over $12–$15+ for mature cohorts, creating powerful unit economics.
How does Nubank maintain a virtually zero customer acquisition cost (CAC)?
Over 80% to 85% of Nubank's new customer signups join organically through word-of-mouth recommendations, social media virality, and referral invites from existing cardholders, insulating Nubank from the multi-hundred-dollar advertising acquisition costs typical of fintech competitors.
