Primary Revenue Streams Deep Dive
Nubank’s monetization model is built around financial services cross-selling.
Instead of charging high upfront fees, the company earns money across multiple financial interactions per customer.
Revenue Stream #1: Interest on Lending
This is Nubank’s largest revenue driver.
The company provides:
- Credit card revolving balances
- Personal loans
- Installment payments
- SME lending
Customers who carry balances on their credit cards pay interest, generating net interest income, which is the core revenue engine of digital banks.
In 2025, Nubank’s net interest income grew rapidly due to expanded lending and improved AI credit models.
Estimated contribution: ~50–60% of total revenue
Pricing model:
- Interest rates vary by borrower risk
- AI-driven underwriting determines limits and rates
Revenue Stream #2: Interchange Fees
Whenever a Nubank credit or debit card is used, the merchant pays a small processing fee.
A portion of that fee goes to Nubank.
Example flow:
Customer purchase → Merchant bank → Payment network → Nubank share
This is called the interchange fee.
Because Nubank has tens of millions of active cards, even small fees generate large revenue.
Estimated contribution: ~15–25%
Pricing model:
- Usually 1%–3% of transaction value
Revenue Stream #3: Banking Services & Account Monetization
Nubank offers digital banking services including:
- Savings accounts
- Payment transfers
- bill payments
- international remittances
Most accounts are free, but Nubank monetizes through:
- float on deposits
- payment processing
- financial transaction services
Estimated revenue share: ~10–15%
Revenue Stream #4: Investment & Wealth Products
Nubank also acts as a financial marketplace.
Customers can buy:
- mutual funds
- stocks
- bonds
- crypto assets
The company earns revenue via:
- brokerage commissions
- management fees
- product referral commissions
Estimated contribution: ~5–10%
Revenue Stream #5: Insurance & Subscription Services
Nubank sells financial protection products like:
- life insurance
- mobile insurance
- personal protection plans
It earns money through insurance brokerage commissions and recurring subscription fees.
Estimated contribution: ~5%
