Monthly payments are calculated as equal fixed amounts, based on the chosen amount, the loan term and an illustrative interest rate. The values are for guidance only.

Choose another amountThis article answers the main questions about the price of a Nubank personal loan in Brazil: how the monthly rate becomes a yearly cost, what the CET adds, how the IOF tax works, what shapes the rate you are offered, which Nubank products are cheaper and how paying early reduces the bill. Examples in reais keep each answer practical.
Direct answer: each simulation in the Nubank app lists a monthly interest rate tailored to you and the CET, which adds the IOF tax and other charges. The figure depends on your profile and on how many instalments you pick. Reports from 2026 mention examples close to 3.3% a month, roughly 47.6% a year once compounded and before tax.
Unsecured personal credit in Brazil is expensive by international standards, and it is usually pricier than payroll loans or loans with collateral. Nubank publishes examples but stresses that each customer receives a tailored rate that can vary with the month and the term, so your own simulation is the only reliable guide to your price.
Looking only at the monthly rate is the classic error. Two loans with the same monthly figure can carry different CETs once taxes and insurance are counted. Underestimating compounding is the other: a rate that seems small each month grows into a large yearly cost. The CET and the total payable tell the full and honest story.
Below, each section answers a single question: how monthly rates compound, how much different rates cost, what the CET includes, how IOF is calculated, what shapes your rate, which Nubank products cost less, what to avoid and how early payment cuts interest, followed by a short plan for paying less on your next personal loan.
How do monthly rates compound?
Interest is charged on the balance each month, and over twelve months the effect compounds. A rate of 2.2% a month equals about 29.8% a year, 2.8% equals about 39.3% and 3.6% equals about 52.9%. Multiplying the monthly rate by twelve understates the real yearly cost.
How much do different rates cost?
Illustrative values for R$6,000 in 18 instalments, before taxes:
| Monthly rate | Instalment | Total interest | Yearly equivalent |
|---|---|---|---|
| 2.2% | R$407 | R$1,331 | About 29.8% |
| 2.8% | R$429 | R$1,720 | About 39.3% |
| 3.6% | R$459 | R$2,256 | About 52.9% |
Moving from 3.6% to 2.2% a month saves more than R$900 on this loan, which shows how much a stronger profile is worth.
What does the CET include?
The CET bundles the interest rate, the IOF tax and any other contract charges, such as insurance, into one yearly percentage. Lenders in Brazil must disclose it so that customers can compare offers fairly. Nubank’s general terms say it does not charge an origination fee, which keeps its CET closer to the interest rate itself.
How is IOF calculated?
IOF is a federal levy on credit. It mixes a flat percentage of the sum with a small daily percentage tied to how long the loan runs, all within legal limits. The rules are updated from time to time, so trust the CET shown in the simulation, which already reflects whatever rate applies today.
What shapes my Nubank rate?
- Paying the card bill in full and on time.
- Your score at the Brazilian credit bureaus.
- Updated income in the app.
- Debts held with other institutions.
- The number of instalments you choose.
Which Nubank products cost less?
| Product | Why it is cheaper | Who can use it |
|---|---|---|
| Payroll loan | Instalments deducted from salary or benefit | Eligible public servants and retirees |
| Loan backed by investments | Collateral lowers the risk | Customers with money invested |
| Renegotiation | Restructures existing debt | Customers already in debt with Nubank |
What should I avoid?
- Deciding on the monthly rate without looking further.
- Skipping the CET and the grand total.
- Using the entire limit when less would do.
- Picking a long plan without checking what it adds.
- Overlooking cheaper credit lines.
How does early payment cut interest?
Brazilian law cuts interest proportionally whenever you pay ahead of time. Bringing forward the final instalments usually saves most, because those still carry the most future interest. Look at the discount displayed in the app, then put a bonus or the thirteenth salary to work.
A plan for paying less next time
- Pay the card bill in full every month.
- Keep your income updated in the app.
- Reduce debts elsewhere.
- Simulate several terms and compare the CET.
- Check whether you qualify for a cheaper credit line.
- Plan early payments from the start.
Is a lower monthly rate always better?
Usually, but not automatically. A slightly lower monthly rate over many more instalments can still cost more in total than a slightly higher rate over a short term. Always compare the total payable and the CET for the exact amount and term you intend to borrow.
Why do Brazilian personal loans cost so much?
High benchmark interest rates, default risk on unsecured credit and taxes such as IOF all push prices up. Products where repayment is more secure, such as payroll deductions or investments used as collateral, carry lower rates for that reason. Understanding these drivers helps you look for the cheapest form of credit first.
How should I compare Nubank with other banks?
Simulate the same amount and number of instalments at each institution and line up the CET and the total payable. Offers change often, so compare on the same day when possible. If the difference is small, consider practical factors such as the app experience and early payment options.
What is a reasonable instalment for my income?
A widely used guideline is to keep all loan instalments together below about 30% of net monthly income. Above that level, unexpected expenses quickly lead to late payments, which damage your score and make future credit more expensive. If the instalment you need is higher, borrow less or wait until other debts are paid down.
| Net monthly income | Suggested maximum for all instalments |
|---|---|
| R$3,000 | About R$900 |
| R$5,000 | About R$1,500 |
| R$8,000 | About R$2,400 |
Can I trust rates I see in adverts?
Adverts show examples, not your price. Your tailored rate only appears in the app simulation, so use it for decisions and comparisons.
When an advert looks unusually cheap, check the conditions carefully: low examples often apply only to payroll loans or to customers with very strong profiles, not to unsecured personal credit for everyone.
Read the small print before deciding.
Summary

- Rates are set for each customer and term.
- Monthly figures compound into a much bigger yearly cost.
- The CET folds in interest and IOF.
- Nubank says it charges no origination fee.
- Paying ahead lowers the interest.
Frequently asked questions
What rate does Nubank charge on personal loans?
Rates are tailored; 2026 reports cite examples around 3.3% a month.
Why is the CET higher than the interest rate?
Because it adds the IOF tax and any other charges to the interest.
Can I lower my rate later?
Improving your payments, income data and debts can lead to better future offers.
Conclusion
Reading Nubank loan rates correctly is essential before borrowing. Convert monthly rates into yearly costs, compare the CET, prefer fewer instalments, consider cheaper credit lines and confirm a loan only when the total payable makes sense.
