You have been repaying your mortgage for several years, and a windfall allows you to pay off part of it. You contact your bank, and the response surprises you: they refuse. Early repayment of a mortgage is a right guaranteed by the Consumer Code, but this right has specific limits that banks legally exploit.
The 10% threshold of the initial amount: the most common restriction
Most refusals do not concern total repayment, but rather a partial repayment deemed too low. Article L.313-47 of the Consumer Code allows banks to prohibit any partial repayment that is less than or equal to 10% of the initial loan amount. Only the complete balance escapes this rule.
In practical terms, if you borrowed 200,000 euros, your bank can refuse an early payment of 15,000 euros. For them to be obliged to accept, you would need to repay more than 20,000 euros, or pay off the entire remaining capital. This threshold is not automatic: it must be stated in your loan agreement. Check the clauses before taking any steps.
The prohibition of early repayments by banks is therefore based less on an absolute blockage than on a contractual clause designed to discourage small partial repayments.
Early repayment penalties: the financial brake of the contract
When the bank cannot refuse repayment, it can, however, make it costly. The early repayment penalties (IRA) represent the main contractual lever. Their amount is capped by law but remains significant on large sums.
The legal cap corresponds to the lower of these two amounts:
- Six months of interest on the capital repaid early, calculated at the average loan rate.
- 3% of the remaining capital before repayment.
These penalties compensate for the bank’s loss of earnings. A mortgage generates interest over its entire duration. When the borrower repays early, the bank loses part of the expected income. The IRAs partially rebalance this loss.
However, three situations eliminate the obligation to pay these penalties: the sale of the property related to a change of workplace, a dismissal (forced cessation of activity), or the death of the borrower or their spouse. These exemptions only apply to loans signed from July 1999 onwards.
Loss of margin and refinancing cost: what the bank calculates internally
Why does a bank prefer that a borrower keeps their loan for as long as possible? The answer lies in two mechanisms that are rarely explained to clients.
The first is the interest margin. When a bank lends at a fixed rate, it borrows itself on the markets at a lower rate. The difference between these two rates constitutes its margin. An early repayment eliminates this margin for all remaining years. The newer the loan, the heavier the loss, as the first years concentrate the largest share of interest.
The second mechanism concerns reinvestment. When market rates fall, the bank recovers capital that it can only reinvest at a lower yield. It is precisely during these periods of decline that borrowers wish to repay or renegotiate, creating an unfavorable scissor effect for the lending institution.
This calculation explains why some banks include strict contractual clauses on partial repayments, even if they cannot block a total repayment.
Contractual clauses and blocking periods: reading your loan offer
Have you ever noticed that mortgage offers span several dozen pages? The conditions for early repayment are included, often in a poorly readable section. Several types of clauses deserve special attention:
- The minimum threshold clause, which sets the minimum amount for partial repayment (generally 10% of the initial capital).
- The IRA clause, which specifies whether penalties will be required and according to what calculation.
- The notice period clause, which imposes a delay (often one month) between the request and the actual repayment.
- The conditions for IRA exemption, sometimes more favorable than the legal minimum if negotiated at signing.
Negotiating the removal of IRAs at the time of signing remains the most effective way to avoid future blockages. Some institutions accept this concession to attract a file, especially when the borrower presents a good risk profile.
The specific case of variable rate loans
Variable rate loans rarely include IRAs. The bank already adjusts its margins based on the market, which reduces its loss of earnings in the event of early repayment. For this type of contract, refusals almost exclusively concern the 10% threshold.
Mortgage and borrower insurance: the domino effect of repayment
Repaying a loan early also terminates the borrower insurance associated with it. The insurer must then refund the portion of the premium corresponding to the uncovered period. This point is often overlooked, but it can represent a significant saving on the total cost of the loan.
On the other hand, if you only make a partial repayment, the insurance continues. Its amount can be recalculated on the remaining capital (insurance on remaining capital) or remain the same (insurance on initial capital). Check the calculation method in your contract before deciding between partial and total repayment.
The elimination of insurance payments, combined with the disappearance of future interest, constitutes the real gain of an early repayment. The IRAs, as discouraging as they may be, are often lower than this double saving, especially when the loan was taken out at a high rate and there are several years of repayment left.
The refusal of an early repayment by a bank is therefore almost never arbitrary. It is based on precise contractual clauses, framed by the Consumer Code. Rereading your loan offer, calculating the amount of IRAs, and checking the cases of exemption before contacting your bank advisor can help avoid a refusal or contest it effectively.
