A consumer credit is a loan granted by a financial institution to an individual for non-professional and non-real estate use, with an amount ranging from 200 to 75,000 euros. Behind this simple definition lie several mechanisms that directly influence the final cost of financing. Understanding these mechanisms before signing helps avoid paying several hundred euros too much over the duration of the loan.
Legal obligation of the lender: a safeguard often ignored
Before even comparing rates, one point deserves attention. French regulations impose on the lender a duty to verify the borrower’s creditworthiness and the suitability of the credit to the borrower’s situation. The bank or institution must analyze your income, expenses, and overall situation before granting you a consumer loan.

This obligation does not stop at a simple questionnaire. The institution must provide you with a standardized pre-contractual information sheet (FIPEN) detailing the type of credit, the amount, the duration, the total cost, the APR, and the penalties in case of delay. This document is required before any signature.
In practice, some borrowers sign without reading this sheet, which amounts to giving up the only document that allows for an objective comparison of two offers. If an institution does not provide it to you spontaneously, it is a warning sign. Platforms like Conso Crédit regularly remind the importance of this step in the subscription process.

APR of consumer credit: the only reliable indicator for comparison
The nominal rate displayed by a lending institution does not reflect the actual cost of credit. Two offers at the same nominal rate can show a significant difference once the application fees and borrower insurance are included.
The APR (annual percentage rate) is the only indicator that aggregates all these elements. It includes interest, mandatory fees, and, if applicable, the cost of insurance. This is what should serve as the basis for any comparison between a personal loan, a earmarked credit, or a revolving credit.
What the APR does not say
The APR assumes a perfectly linear repayment, without incident. It does not take into account late penalties or fees related to partial early repayment. Before signing, check two specific clauses in your contract:
- Early repayment penalties: some contracts cap them, while others eliminate them entirely, which can represent a significant saving if you pay off the credit earlier than expected.
- Postponement fees: the possibility of deferring one or two payments is offered by several institutions, but the conditions (free or charged, number of allowed deferrals) vary from one contract to another.
- Optional borrower insurance: often checked by default in online forms, it can represent a significant part of the total cost. For a low-amount personal loan, it is rarely relevant.
Earmarked credit or personal loan: choose according to the project
Earmarked credit finances a specific purchase (car, renovations, appliances). The contract is linked to the order form: if the sale is canceled, the credit is also canceled. This legal protection has a counterpart: the funds can only be used for the designated purchase, and the rates offered depend on the nature of the good.
The personal loan, on the other hand, allows the borrower to use the amount as they see fit. This flexibility sometimes comes at a slightly higher rate, but it avoids multiplying credits when several expenses accumulate (moving and buying furniture, for example).
The trap of revolving credit
Revolving credit (formerly “revolving”) provides a replenishable reserve of money. Its APR is significantly higher than that of a classic personal loan. A revolving credit often costs two to three times more than a personal loan for the same borrowed amount.
It is sometimes offered automatically during an in-store purchase, via a payment card issued by the retailer. Refusing this option and requesting a classic earmarked credit significantly reduces the final bill.

Repayment duration and monthly payments: the arbitration that changes the total cost
Extending the duration of a consumer credit decreases the monthly payment but mechanically increases the total cost. The relationship is not proportional: beyond a certain threshold, each additional month generates an increasingly visible interest surcharge.
A credit simulator allows you to visualize this effect. By testing three or four different durations for the same amount, the difference in total cost becomes clear. Choosing the highest monthly payment compatible with your budget reduces the actual price of financing.
Also check the one-third rule: the sum of your credit monthly payments (across all loans) should not exceed one-third of your net income. This ratio is not an absolute regulatory standard for consumer credit, but it is the threshold used by most lending institutions to assess your application.
- A short-term project (less than 12 months) can often be financed by a short-term personal loan, where the total cost remains low.
- A car or renovation project generally spans 24 to 60 months, with earmarked credit whose APR is negotiated based on the good.
- Beyond 60 months, the interest surcharge justifies questioning whether the borrowed amount is truly suited to the project.
The best consumer credit is not the one that displays the lowest rate on an advertising banner. It is the one whose APR, duration, and contractual clauses precisely match your project and your repayment capacity. Reading the FIPEN, comparing at least three offers based on the APR, and refusing the options checked by default: these three reflexes are enough to avoid most unnecessary extra costs.
