Renegotiating a Mortgage Loan: When Paying It Off Makes Sense

Paris – 08.08.2026: Early repayment or renegotiation of a mortgage loan can ease the financial burden on households. Whether it is actually worthwhile, however, depends on several factors: the contractual borrowing rate, the remaining loan amount, the remaining term, possible early repayment penalties, as well as the return and availability of personal savings.

The Banque de France put the average interest rate on new housing loans excluding refinancing in May 2026 at 3.21 percent. Those who took out their existing loan at a significantly lower fixed rate will therefore generally not save money by switching. For older contracts with higher interest rates, an assessment may be worthwhile if a long term and a sufficiently high outstanding balance remain.

Two options must be distinguished: renegotiation with the current bank and repayment through another institution. Processing fees may apply for a contract amendment. Switching banks often involves costs for early repayment, new loan security and, where applicable, different insurance. The total cost of the new financing should therefore be compared, rather than merely the nominal interest rate offered.

For fixed-rate mortgage loans, compensation for early repayment is legally capped. It may not exceed six months’ interest on the repaid amount at the average loan rate and must also not exceed three percent of the capital previously outstanding. Borrowers can request a breakdown of costs from their bank. For contracts concluded since 1 July 2016, this information must be provided free of charge.

Making an additional repayment from savings also requires a sober calculation. It reduces future interest payments and, depending on the contract, shortens the term or lowers the monthly payment. At the same time, the funds used are no longer available for repairs, loss of income or other unexpected expenses. A sufficient liquidity buffer should therefore be maintained. Contracts may also stipulate minimum amounts or annual caps for additional repayments.

The intended use of the property also affects the outcome. For owner-occupied homes, secure interest savings are generally the main consideration. For rented properties, interest on debt may be tax-relevant, making an individual calculation particularly important. The national housing agency ANIL considers switching loans economically attractive primarily when the new interest rate is significantly lower and the remaining term is long.

The comparison requires the repayment schedule for the existing loan, the current outstanding balance, a written cost breakdown from the bank and a complete alternative offer. Refinancing is financially beneficial only when the interest saved exceeds all switching costs, possible additional insurance costs and the loss of available liquidity.
