How the credit portability comparison works
What the page compares
Portability means moving a loan you already have to another institution, which pays off the old contract with its own money and becomes the lender. The page compares the two ways forward you have in front of you: keep paying the contract as it is, or accept the proposal. Because the new institution's money pays off the balance owed to the original one, both ways start from the same balance, and that is why they can be compared by the effective interest rate, with everything each one charges counted, and also by the total paid and by how long the costs up front take to pay back.
What you enter
- Your loan today: the balance owed that the institution gives for the transfer, the installment you pay, with the insurance and any monthly charge that comes with it, and how many installments are left. You do not need to know the rate of the contract: the page finds it from those three figures.
- The proposal: the installment and the number of installments, which is what the formal proposal shows, or the effective monthly or annual rate with the term, in which case the installment is worked out as a fixed one. If the proposal has a monthly insurance, describe it by its installment.
- The costs charged up front: fees, tax and insurance the proposal charges at signing, as it states them. The page does not estimate any of them: what is not typed does not enter the calculation.
How the calculation works
The rate you pay today is the one at which the installments left repay the balance, the same calculation as on the contract check page. The proposal's rate is the one at which its installments repay the balance less the costs up front, because what you pay at signing is not lent: it works like a fee taken out of the amount received, which makes credit dearer. It is the total effective cost of the proposal, as long as the costs you typed are all of them. The total paid adds up the installments of each way, and for the proposal also the costs up front, without bringing the money to present value. The break-even is the first month in which what the proposal saves on the installments, added up month by month, has covered the costs paid up front.
An example with numbers
A loan with a balance of R$ 20,000.00 and 24 installments of R$ 1,118.26 still to pay, which is 2.50% a month, or 34.49% a year. Another institution proposes 24 installments of R$ 1,033.62 and charges R$ 300.00 up front.
| Measure | Today | Proposal |
|---|---|---|
| Installment | R$ 1,118.26 | R$ 1,033.62 |
| Costs up front | R$ 0.00 | R$ 300.00 |
| Paid in all | R$ 26,838.24 | R$ 25,106.88 |
| Effective cost a month | 2.50% | 1.93% |
| Effective cost a year | 34.49% | 25.82% |
The proposal costs less: the installment falls R$ 84.64 a month and you pay R$ 1,731.36 less in all, and the R$ 300.00 charged up front pays back in the fourth month. Without those costs the effective cost would be the proposal's own rate, 1.80% a month (23.87% a year), and the saving R$ 2,031.36. With R$ 1,500.00 up front the effective cost rises to 2.49% a month, almost the same as today's, the saving falls to R$ 531.36 and the costs only pay back in the 18th month. With R$ 3,000.00 the proposal comes to cost more: 3.27% a month and R$ 968.64 more in all.
The term misleads too. A proposal of 120 installments of R$ 286.94 has an effective cost of 1.00% a month, lower than today's, but adds up to R$ 34,432.80, which is R$ 7,594.56 more than the R$ 26,838.24 left to pay. That is why the page compares the rates and warns when the proposal's term is longer than what is left.
What the rule says
Portability is regulated by Resolução CMN 5.057/2022, amended since, among others, by Resolução CMN 5.265/2025, which added Open Finance as a way for the institutions to exchange information. You are the one who asks, of the institution that wants to take the loan over; it takes the request to the original one together with the proposal, which carries the nominal and effective rates, the total effective cost, the term, the amortization system and the amount of the installments (art. 7). In the same kind of credit, the amount and the term of the new operation cannot exceed the balance owed and the term left, and a higher installment needs your formal agreement; moving the contract to another kind of credit is possible, and then the term limit does not apply (art. 6). What the exchange of information and the transfer of funds between the institutions cost, and the reimbursement the original one may ask of the new one, cannot be passed on to you (arts. 15 and 16). The text of the rule is on the central bank's website, and it is the text that counts, not this summary.
Mistakes to avoid
- Comparing only the installment. A lower installment can come from a much longer term, and the total paid, not only the installment, shows what that costs.
- Forgetting the costs up front. They enter the effective cost and can erase the advantage of a lower rate, as in the R$ 1,500.00 example.
- Comparing the proposal's nominal rate with today's effective one. Compare rates of the same kind, both effective and with everything counted.
- Using a balance that is not the institution's. The balance the institution gives for the transfer is the one that counts, and it can differ a little from the one you worked out.
- Taking a market average for an offer. The position of the rates among those reported to the central bank is a reference to operations already made, not a proposal for you.
What the page does not cover
The page compares fixed-installment loans in Brazil. A contract with decreasing or variable installments, the portability of credit card and overdraft debt, and the estimate of the IOF tax are left out. The calculation assumes the new loan is for the balance owed, that nothing changes until the end and that you can pay whatever the proposal charges up front. It does not say which institution to choose or whether you should move the contract: it is a comparison with the assumptions it states, not a recommendation.
Where to go next
The guide on credit portability explains what the proposal has to show and how to read the effective cost, and the guide on the total effective cost shows why it is the right number to compare. To see where a rate falls among those reported to the central bank, use the Is my rate high? page; the methodology page describes how the calculations are made.
