People rarely seek credit out of curiosity. The starting point is a specific project: replacing a failing car, financing renovations before winter, acquiring a first apartment. The type of credit that is suitable directly depends on this initial situation, and the choice has concrete consequences on the total cost, repayment flexibility, and future borrowing capacity.
Actual cost of credit: what the monthly payment doesn’t tell you
When comparing two loan offers, the natural reflex is to look at the monthly payment. A low monthly payment is reassuring, but it often hides an extension of the duration that inflates the total cost. In 2026, the average duration of mortgage loans is around 254 months, which is over 21 years. Banks are willing to extend this duration to maintain accessibility, but each additional month generates interest.
The true indicator is the total cost of the credit, not the isolated monthly payment. This cost includes accumulated interest, borrower insurance, and processing fees. Two loans at the same nominal rate can lead to significant differences if one lasts 15 years and the other lasts 25 years.

Mortgage credit: amortizable loan, in fine, or bridge loan
The amortizable loan remains the most common option for purchasing a home. Each monthly payment repays a portion of the principal and a portion of interest. Over time, the proportion of principal increases. You know exactly when the loan ends, which makes budget management easier.
The in fine loan works differently: you only repay the interest throughout the duration, then the principal in one lump sum at maturity. This arrangement mainly interests rental investors who place the capital in a parallel savings vehicle. For purchasing a primary residence, the in fine loan is rarely relevant as it requires solid savings from the start.
The bridge loan addresses a specific constraint: buying a new property before selling the old one. The bank advances a portion of the estimated value of the property for sale. The applicable usury rate for bridge loans reaches 6.39% as of July 1, 2026, significantly higher than traditional fixed-rate loans. This extra cost is justified by the risk that the sale may drag on or that the price obtained may be lower than expected.
Consumer credit: three formulas, three logics
Consumer credit encompasses very different products. Confusing them risks paying more or ending up with an unsuitable option.
- Targeted credit finances a specific purchase (car, appliances, renovations). If the sale is canceled, the credit is also canceled. This contractual protection makes it the safest choice when you know exactly what you’re buying.
- The personal loan allows the borrower to use the funds as they wish. No purchase justification is required, but there is also no safety net in case of problems with the seller.
- The revolving credit provides a reserve of money that can be used in full or in parts. Revolving credit rates are often the highest among consumer credits, making it expensive as soon as the balance is left to run.
For one-off and identified expenses, targeted credit or personal loans remain more economical. Revolving credit can help with small amounts as long as you repay quickly.
Usury rate and duration: the two variables that change everything
The usury rate is the legal ceiling beyond which a bank cannot lend. It varies according to the type of credit and duration. As of July 1, 2026, the usury rate for a fixed mortgage loan of 20 years or more reaches 5.29%. This ceiling protects the borrower, but it can also block a file when the rate proposed by the bank, plus insurance and fees, exceeds the threshold.
In practice, the duration of the loan directly modifies the applicable usury rate. A loan over 10 years is not subject to the same ceiling as a loan over 25 years. This mechanism pushes some borrowers to adjust the duration to stay below the threshold, even if it means accepting higher monthly payments.
Opinions vary on this point, but extending the duration to the maximum to reduce the monthly payment is not always the right strategy. You gain in monthly comfort, but you lose on the total cost and sometimes on eligibility for the usury rate.
Professional credit: distinct rules for businesses
Professional credit follows a different logic. The average rates for new business loans are currently lower in France than the average in the Eurozone, which benefits project holders. The Banque de France distinguishes conditions based on the size of the business: a very small enterprise does not receive the same terms as a large group.
A regulatory point to remember: the usury rate does not apply to most professional loans, except for overdrafts. This absence of a ceiling gives banks more room for negotiation, but also borrowers who present a solid file. For a self-employed person or a craftsman, negotiating the rate and the guarantees required weighs more than for an individual.
Choosing a credit involves balancing monthly payment, duration, total cost, and level of protection. A targeted loan offers better protection than a personal loan, an amortizable loan costs less than an in fine loan for a primary residence, and a fixed rate provides more security than a variable rate when rates rise. Starting from a concrete project, checking the applicable usury rate, and comparing the total cost over the entire duration remains the most reliable method to avoid unpleasant surprises.
