Why do credit cards still dominate installment purchases in Brazil?
Advertisements
Installment payments via Pix already exist, personal loan apps are growing, and digital banks promise a revolution.
Even so, when it comes to buying a new sofa, a refrigerator, or a laptop, most people still pull out their credit card.
It's neither stubbornness nor nostalgia.
That's because the Brazilian system of interest-free installment payments has created a near-perfect match between what the retailer wants to sell and what the consumer wants (and can) pay.
Many people think this is just a "culture of installment payments." There's a bit of that, yes. But the main thing is structural: the retailer pays you to pay in installments without interest.
He gives up part of the profit in the expectation of selling for a higher price and faster.
The customer gets the postponement at no explicit cost and, as a bonus, also accumulates points, miles, or cashback.
It's a triangulation that few forms of payment have managed to replicate with the same fluidity.

Why Credit cards still dominate installment purchases. Even with so many new options?
Interest-free installment payments are not a favor from the card issuer. It's an aggressive commercial negotiation between retailers and acquirers.
The retailer accepts a higher MDR (merchant discount rate) precisely to offer 10x, 12x, or even 18x installments without additional charges.
It transforms the cost of financing into a conversion tool.
Meanwhile, Pix installment payments — which many banks launched in 2024 and 2025 — charge interest to the customer from day one.
The retailer receives payment upfront, but you're the one who pays the financing bill.
The difference seems small in the advertisement, but in practice it adds up: a purchase of R$ 4,000 in 12 installments on a credit card with no interest costs exactly R$ 4,000.
With Pix installments, depending on the rate, it can become R$ 4,400 or more.
And there's another detail that almost no one mentions: the card already has a pre-approved credit limit.
You don't need to send proof of income at the time of purchase, nor do you have to wait two days for approval.
It's instantaneous. This emotional speed matters much more than people admit.

How interest-free installment payments really work (and why nobody explains it properly)
On the surface it's simple: you pay in installments, the store receives less, and the payment processor takes a larger cut of the fee. In practice, it's a delicate mechanism.
The retailer calculates the full price already taking into account that they will offer installment payments.
Many products are artificially priced higher when purchased "cash" so that the interest-free installment plan seems advantageous.
It's a classic example of behavioral pricing: the customer feels they are getting a discount by paying in installments, when in reality they are paying the "normal" price that the store always wanted.
There's something almost poetic about it.
++ How the "Invisible Installment Effect" Destroys Your Budget Without You Realizing It
Brazilians transformed a commercial discount rate into a feeling of accomplishment.
And instead of fighting back, the credit card companies rode the wave: they created points programs that transform that same purchase into miles, category upgrades, and access to VIP lounges.
It's behavioral capitalism, but in a Rio de Janeiro version.
Advantages that go beyond your wallet (and that Pix doesn't yet offer)
Security comes first. Disputing a credit card purchase is relatively easy: the provisional refund arrives quickly, and the burden of proof lies with the merchant.
With Pix installment payments or digital credit, reversals depend much more on the seller's goodwill or the bank's bureaucracy.
Then come the invisible layers: insurance against theft or damage upon purchase, extended warranty, price protection.
Many people only discover these benefits when something goes wrong — and then they become loyal customers.
And, of course, the rewards. It's no exaggeration to say that, for those who travel or use their card frequently, the real cost of many purchases drops by 3-8% just from accumulating points. This doesn't exist (yet) with Pix installments.

Two real portraits from 2025
A 34-year-old manicurist in Sorocaba needed a used car to transport her clients. She found a 2019 hatchback for R$ 52 thousand. Paying in cash was not feasible.
With her card (a gold card with no annual fee), she got 12 interest-free installments plus 1.8 points per real spent.
He picked up the car the following week and, with the miles accumulated throughout the year, managed to get a round-trip ticket to the Northeast for his daughter's vacation.
Without the credit card installment plan, it would have been a payroll loan with an interest rate of 3.5% per month.
Another example: a young couple renovating a rented apartment. They bought R$ 9,800 worth of furniture from a large chain store.
They paid in 10 installments using the husband's black credit card. They earned 27,000 points (equivalent to almost R$ 800 in flights).
If they had used Pix installments with 1,99% am, they would have paid about R$ 1,400 more in interest — money that could have been used for a trip or an emergency fund.
Direct comparison (no beating around the bush)
| Item | Interest-free card | Pix installments | CDC / direct financing |
|---|---|---|---|
| Cost-effective for the customer | Zero (in most cases) | Interest rates of 1.5–3.99% am. | 2–5% am. |
| Rewards | Points / miles / cashback | Virtually zero | Zero |
| Purchase dispute | Fast and efficient | Slow and uncertain | Very bureaucratic |
| Release time | Immediate | Immediate | 1–5 business days |
| Retail acceptance | Almost 100% | Growing, but incomplete. | Limited to partners |
An analogy that sticks in your head.
A credit card with installment payments is like a short-term social elevator: it takes you to the floor you want without having to climb stairs carrying heavy loads.
Paying in installments via Pix is like an escalator — it goes up, but you pay extra energy for each step.
Traditional financing is like a service ladder: you get there, but it's hard-earned, expensive, and time-consuming.
Credit cards still dominate installment purchases: Questions that come up all the time.
| Common question | No-nonsense answer |
|---|---|
| Will paying in installments with my credit card put me in debt? | Only if you spend more than you can afford to pay. Interest-free loans don't create debt, they just extend the payment period. |
| Will Pix installment payments kill off credit cards? | Doubtful. As long as it doesn't offer points, protection, and zero-cost installment payments, no. |
| Is a credit card with an annual fee worth it? | It depends. The ones without an annual fee already offer a lot. The premium ones are worthwhile for those who travel or spend a lot. |
| How can I avoid losing control of my installments? | Bank app + simple spreadsheet. The transparency of the card is one of the great advantages. |
In conclusion, the reasoning continues...
Credit cards still dominate installment purchases. Because they created — and maintain — an ecosystem that aligns retailer incentives, customer convenience, and profitability for the financial industry.
It's not unbeatable forever.
But as long as the cost of installment payments continues to be paid primarily by the seller (and not the buyer), and as long as the rewards continue to exist, it will remain the default choice.
And you, have you ever noticed how many important things in your life only became a reality because someone let you pay in 10 or 12 installments without interest?
