What paying ahead costs
Amounts to pay on the next due date, 12/2/2026, without the interest that has not yet accrued, at the contract's rate.
Settle the whole debt
- Paying R$ 20,359.99 on 12/2/2026 settles the debt and saves you R$ 4,446.77 in interest.
Advance only the last installments
The installments you advance are always the last ones, which have the most interest still to come. The others keep being paid on their usual dates.
Extra payments
Money paid on top of the instalment goes straight against the balance. See what it buys.

How the quote for settling or advancing installments works
What the page calculates
Someone who is already paying off a loan usually wants to know two things: what it costs to settle everything today, and what it costs to pay only the last few installments ahead of time. The answer is not the sum of the installments, because an installment paid before its due date is an installment without the interest for the time that was still left. The page calculates that amount for what is left of your contract, on the date of the next installment, and shows how much interest you stop paying. Right below the quote is the extra payments simulator, for anyone who would rather pay more without settling.
What you enter
- Today's balance owed and the installments still to pay, counting the next one. Both numbers are on the statement or in the bank's app.
- The contract's rate, not the total effective cost. The quote discounts each installment at the interest rate that accrues with time. The total effective cost also holds fees and insurance, which do not grow month by month, and using it would discount too much.
- The amortization system (PRICE or SAC) and the date of the next installment. The system defines how the installments are built, and the date is the day the quote is for.
For a contract saved under My debts this data is already stored, and the "Simulate paying ahead" button uses it. Contracts still in a grace period, or saved with extra payments already planned, do not offer it, because what is left of them is not a plain loan.
How the sum is done
For the calculation, what is left of a loan is a new loan: today's balance, the installments that remain, the same rate and the same system. Each advanced installment is brought back to the date of the next installment, divided by one plus the monthly rate, raised to the number of months that were left before it. The next installment falls due that very day and counts in full, the following one is discounted one month, the next two, and so on. When you advance the last installments, the others keep being paid on their usual dates, and the last ones are precisely those with the most interest still to come. Settling everything comes down to something simple: the balance owed plus one month of interest. The discount is the difference between what the installments added up to on their due dates and what is paid now, the same principle as the proportional reduction of interest that the guide on paying ahead explains.
A worked example
R$ 20,000.00 balance owed, 24 installments remaining, interest of 1.8% a month, PRICE system. The installment is about R$ 1,033.62, and the 24 add up to R$ 24,806.76:
| Advance | Amount to pay | Added up on due dates | Interest you stop paying |
|---|---|---|---|
| The last installment | R$ 685.66 | R$ 1,033.50 | R$ 347.84 |
| The last 6 | R$ 4,304.04 | R$ 6,201.60 | R$ 1,897.56 |
| The last 12 | R$ 9,094.43 | R$ 12,403.32 | R$ 3,308.89 |
| All of them (settle) | R$ 20,359.99 | R$ 24,806.76 | R$ 4,446.77 |
Settling costs the balance, R$ 20,000.00, plus one month of interest, R$ 360.00, that is, R$ 20,360.00. The quote shows R$ 20,359.99 because the installments in the schedule are rounded to cents. Under SAC, with the same balance, term and rate, settling everything costs the same R$ 20,359.99: what sets the price of settling is the balance, the rate and the date, not the system. Advancing only the last 12 installments, however, costs R$ 8,218.18 under SAC against R$ 9,094.43 under PRICE, because the last installments of a SAC loan are smaller.
Mistakes to avoid
- Treating the quote as the final amount. It holds for the day of the next due date and is a reference for checking the lender's offer; the exact figure is the one on the lender's settlement statement.
- Using the total effective cost instead of the contract's rate. The discount comes out inflated and the amount to pay lower than the real one.
- Ignoring monthly insurance and fees. The quote counts only principal and interest; whether the insurance ends with the debt is for the lender to say.
- Settling with money you may need. An emergency fund stays out of this sum: if it is used and the need arises, the debt comes back, and dearer.
What the page does not cover
The quote does not include settlement fees the contract may provide for, does not count the exact days between today and the due date, does not handle contracts with a grace period still ahead or with payments already planned, and does not model an index that changes the rate along the way. Nor does it say whether it is worth it: it shows the price, not the decision. To compare settling with investing, use the pay off or invest page.
Where to go next
The guide on paying off a loan early explains the right to settle early and what to check in the offer. To see how much an extra payment saves in a loan's schedule, use the simulation, and the methodology page describes how the calculations are done.
