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.
Illustrative amounts and interest rates. This is not a loan offer or credit approval.
Choose another amountHere we take the loan simulator in the Nubank app apart: where it sits, how to set the amount and instalments, how to read the monthly rate beside the yearly cost and the CET and how to judge an offer properly. Examples in reais show how quickly totals climb as instalments rise, even when the monthly rate looks quite small.
Direct answer: tap borrowing in the Nubank app, set a sum, pick how many instalments you want and study the monthly rate, the CET and what you would pay in total. Running simulations is free and you can repeat them as often as you like. Nothing is contracted until you type the four-digit password of your Nubank card to confirm.
Nubank serves customers in Brazil, Mexico and Colombia, and Brazilians handle the entire personal loan inside the app. The bank currently explains that each customer gets a tailored rate that can shift with the calendar month and with the number of instalments, which is why two simulations a few weeks apart rarely look identical.
The most expensive habit is choosing by instalment size alone. A smaller instalment almost always means more months and a much larger total. The second is ignoring the CET, which adds the IOF tax and other charges to the interest. The total payable and the CET are the two figures that reveal what the loan really costs.
In the sections below you will find where the simulator lives, a table of instalment scenarios, how monthly rates compound into yearly costs, what the CET includes, a method for choosing the term, frequent errors, the right to withdraw, how early repayment cuts interest and a plan to compare Nubank with cheaper options before confirming anything.
Where the simulator lives
- Find the borrowing shortcut on the app’s home screen.
- Pick the option to work out a loan.
- Choose a sum inside the limit you are shown.
- Select how many instalments you want and, where possible, the first due date.
- Study the monthly rate, the CET and the grand total.
- Close the screen, or confirm with your card password.
Instalment scenarios
Illustrative values for R$4,000, before taxes, at two monthly rates:
| Monthly rate | Instalments | Instalment value | Total interest |
|---|---|---|---|
| 3.0% | 12 | R$402 | R$822 |
| 3.0% | 24 | R$236 | R$1,669 |
| 4.0% | 12 | R$426 | R$1,115 |
| 4.0% | 24 | R$262 | R$2,296 |
Going from 12 to 24 instalments cuts each payment sharply yet pushes interest up by roughly double. Taxes and other charges captured in the CET then sit on top of these amounts.
How monthly rates compound
- 3% a month is about 42.6% a year.
- 4% a month is about 60.1% a year.
- The CET will be higher still once taxes are added.
- Small monthly differences become large yearly ones.
What the CET includes
The CET packs the interest rate, the IOF credit tax and any other contract charges into one yearly percentage. Brazilian rules make lenders show it precisely so that people can compare offers fairly. Because Nubank says it charges no origination fee, its CET usually stays close to the interest rate itself.
Choosing the term
- Write down every fixed monthly cost you have.
- Keep the sum of all loan instalments below roughly 30% of take-home pay.
- Begin with the shortest plan you can manage.
- See whether the rate moves as the plan gets longer.
- Set the due date just after payday.
Frequent errors
- Looking only at the instalment value.
- Ignoring the CET and IOF.
- Taking the whole available limit.
- Stretching the term to make the payment feel lighter.
- Confirming without comparing other options.
Right to withdraw
Nubank’s terms describe a seven-day cooling-off window: cancel within it by handing back the money plus the IOF charged. Read your own contract to be sure, and move quickly if you realise the loan was a mistake.
Paying early
Under Brazilian rules, paying ahead of schedule brings a proportional cut in interest. The app lets you bring instalments forward or clear the whole balance. Putting a bonus or the thirteenth salary towards the final instalments usually saves the most, since those carry the most interest still to come.
Comparing with cheaper options
Payroll loans, loans backed by investments and offers from other banks may carry lower CETs. Simulate each with the same amount and number of instalments and compare the total payable. Unsecured personal loans are convenient, but they are rarely the cheapest form of credit in Brazil.
| Option | Typical advantage | Typical requirement |
|---|---|---|
| Payroll loan | Much lower rates | Eligible public servants or retirees |
| Loan backed by investments | Lower risk, lower rate | Money invested at the bank |
| Unsecured personal loan | Fast and simple | Approval in internal analysis |
Protecting yourself
No genuine Nubank loan requires a payment before release. Messages that ask for money in exchange for Nubank credit are fraud. Simulate and confirm only inside the official app, and keep your card password and verification codes to yourself.
A worked decision
Imagine Carla needs R$4,000 and sees a 3% monthly rate. Twelve instalments of about R$402 fit her budget, while 24 instalments of about R$236 feel easier but cost roughly R$850 more in interest. She chooses twelve and plans to anticipate the last two with her thirteenth salary, cutting the cost further.
Reading the simulation screen
| Field | What to check |
|---|---|
| Amount | The money credited to your account |
| Instalments | How many and how much each |
| Monthly rate | Interest charged each month |
| CET | Total effective cost including IOF |
| First due date | When the first payment is taken |
If any field is unclear, take a screenshot and review it calmly before confirming. There is no time limit on simulations, so a pause costs nothing.
Keeping instalments manageable
A useful test is to imagine an unexpected bill in the same month as an instalment. If paying both would force you to delay the credit card bill, the instalment is too high. Choose a smaller amount or, as a last resort, a slightly longer plan, and keep building a reserve in the account.
When to wait
If every simulation shows an instalment that would strain your budget, it may be better to wait, reduce other debts or save part of the amount first. A loan taken under pressure is more likely to cause late payments, which hurt your score and make future offers more expensive.
Patience here usually costs far less than a rushed loan.
Take your time before confirming.
Rushing rarely pays.
Summary
Summary: the Nubank simulator lets you try any sum and number of instalments and shows the monthly rate, the CET and the grand total. Decide on the total and the CET rather than the instalment, and look at cheaper credit lines first.
- Free and unlimited simulations.
- Tailored rates that vary with the term.
- CET includes interest and IOF.
- Fewer instalments mean less interest.
- Confirm only in the official app.
Frequently asked questions
Does a Nubank simulation create a contract?
No, the contract only exists once you confirm with your card password.
Why does the rate change between simulations?
Because Nubank tailors rates and lets them shift with the month and the length of the plan.
Can I reduce interest after contracting?
Yes, anticipating instalments reduces interest proportionally.
Conclusion
Careful simulating a Nubank loan is your best protection against costly debt. Try several sums and instalment plans, compare the CET and the grand total, check cheaper credit lines and confirm only when the instalment sits comfortably in your budget.
