Brazil Car Loan Calculator
Data verified on
Brazilian car loans are quoted at a monthly interest rate, and the resulting cost surprises most buyers. Enter the vehicle price, your down payment, the monthly rate from the contract and the term. The calculator applies the standard CDC fixed-payment structure and shows the monthly installment, total interest, full cost and — crucially — the percentage you pay above what the car is actually worth.
How Brazilian car financing works
The dominant product is CDC (Crédito Direto ao Consumidor): a fixed-installment loan on the PRICE amortization table, with the vehicle pledged to the lender under alienação fiduciária until the final payment clears. The installment follows PMT = PV × i ÷ [1 − (1 + i)⁻ⁿ].
The single most important thing to know: rates are quoted per month, not per year. A quoted "1.8%" means 1.8% monthly, which compounds to 23.87% annually. Confusing the two understates the true cost by an order of magnitude.
On the default example — R$80,000 car, R$20,000 down, 1.8% per month over 48 months — you finance R$60,000, pay R$1,877.36 a month, and hand over R$110,113.24 in total. That is R$30,113.24 of interest, or 37.64% on top of the sticker price.
| Term | Monthly payment | Total interest | Total cost | Above sticker |
|---|---|---|---|---|
| 12 months | R$5,604.12 | R$7,249.42 | R$87,249.42 | 9.06% |
| 24 months | R$3,100.85 | R$14,420.40 | R$94,420.40 | 18.03% |
| 36 months | R$2,279.03 | R$22,045.08 | R$102,045.08 | 27.56% |
| 48 months | R$1,877.36 | R$30,113.24 | R$110,113.24 | 37.64% |
| 60 months | R$1,643.52 | R$38,611.08 | R$118,611.08 | 48.26% |
Why car rates dwarf mortgage rates in Brazil
In June 2026 the Brazilian Central Bank put the average car loan rate for individuals at roughly 1.97% per month — close to 26% per year. Regulated mortgage lending in the same month ran at 10.82% per year, about 0.86% per month. Car credit costs more than double.
Collateral quality explains most of the gap. A property appreciates, is easy to appraise and cannot be moved; a car depreciates fast, can be crashed or stolen, and its resale value falls faster than the loan balance in the early months.
Car loans also sit in the "recursos livres" (free credit) segment, without access to the cheap directed funding from savings deposits that subsidizes housing credit, and the segment carries structurally higher default rates.
IOF, fees and the CET — what is not in this calculation
The calculator isolates the effect of the interest rate you enter. Real contracts add IOF (a federal financial transactions tax charged daily on the financed amount, capped at 365 days, plus a fixed additional rate), a one-off origination fee (TAC), the Detran lien registration cost and, frequently, a bundled credit-life insurance policy.
These charges are usually rolled into the financed amount, which means you pay interest on them too. Together they push the CET (Custo Efetivo Total — the legally mandated effective total cost) meaningfully above the headline rate.
Brazilian lenders must disclose the CET before signing. Compare offers on CET, never on the advertised rate or the monthly installment — two offers with an identical payment can hide very different terms and total costs.
Cutting the cost
A larger down payment is the most effective lever: it shrinks the financed amount and typically earns a lower rate. Shortening the term is the second: dropping from 60 to 48 months on the example saves R$8,498 in interest for R$233.84 more per month.
Shop the rate in at least three places — your own bank, the manufacturer captive lender (which often subsidizes rates on specific models to clear inventory) and an independent finance company. Watch for the trade-off where a promotional rate comes with a smaller discount on the car itself: compare total outlay, not the rate alone.
Two alternatives exist. Consórcio charges an administration fee instead of interest but gives no guaranteed delivery date, suiting planned purchases rather than urgent ones. Leasing keeps the vehicle titled to the lessor and is now rare for individuals in Brazil. Early payoff is a consumer right under Brazilian law, with a proportional reduction of unaccrued interest.
Frequently asked questions
Is the Brazilian car loan rate monthly or annual?
Monthly, almost always. A "1.8%" quote means 1.8% per month, which compounds to 23.87% per year. This is the most common misunderstanding in the market — always confirm the period explicitly before comparing offers.
How much interest will I pay on a R$80,000 car?
With R$20,000 down at 1.8% per month over 48 months, interest totals R$30,113.24 — 37.64% above the sticker price, for a total outlay of R$110,113.24. Stretching to 60 months raises the interest to R$38,611.08.
Does the calculator include IOF and fees?
No. It applies only the interest rate you enter. Real contracts add IOF, an origination fee, lien registration and often bundled insurance, typically financed alongside the loan, so the CET always exceeds the nominal rate.
Can I pay the loan off early?
Yes. Brazilian consumer law guarantees the right to prepay with a proportional reduction of interest not yet accrued. Ask the lender for the updated payoff balance with the discount applied and check the calculation.
