Taking out a loan commits a fixed share of your income for several months, sometimes several years. The total cost depends less on the amount borrowed than on the combination of loan type, repayment term and interest rate. Comparing these factors before signing helps you identify the financing option that truly fits your budget.
Total cost of credit: comparison by loan type
The APR (annual percentage rate) is the only legally recognised indicator for comparing two offers, as it includes interest, arrangement fees and borrower insurance. Depending on the type of credit, the cost can vary threefold for the same amount borrowed.
| Type of credit | Purpose | Typical APR | Typical term | Use cases |
|---|---|---|---|---|
| Personal loan | Unrestricted | Moderate | 12 to 84 months | Cash flow, various projects |
| Purpose-specific loan | Specific goods or services | Often lower | 12 to 60 months | Car, home improvements, equipment |
| Revolving credit | Unrestricted | High | Variable (renewed annually) | Occasional expenses, small amounts |
A purpose-specific loan has an advantage that is rarely highlighted: if the goods are not delivered or the service is cancelled, the loan agreement can also be cancelled. A personal loan, on the other hand, remains payable even if the project falls through.
Revolving credit carries the highest rates. Its flexibility can hide a pitfall: interest is recalculated on the remaining available balance, which mechanically extends the repayment period if you only make the minimum monthly payment.

Debt-to-income ratio and monthly payments: thresholds that determine bank approval
Lenders apply a simple ratio: your monthly loan payments must not exceed 35% of your net income. This cap includes all your existing commitments (mortgage, car loan, revolving credit).
One detail can make all the difference: disposable income. Two households with the same debt-to-income ratio do not have the same financial leeway if one earns 2,000 euros net and the other 4,500 euros. The bank also assesses your fixed expenses (rent, child support, subscriptions) to estimate what you have left after paying all your instalments.
Run a simulation before committing
A loan calculator lets you test different term and amount combinations and see how they affect your monthly payments. Extending the term lowers the monthly payment but increases the total cost of the loan, sometimes significantly.
- Over 24 months, interest accounts for a moderate share of the amount borrowed, while putting more pressure on your monthly budget.
- Over 60 months, the monthly payment is lower, but total interest can add several hundred euros to the cost.
- Over 84 months (the typical maximum term for a personal loan), the total cost of credit is highest for the same APR.
The shortest term your budget can comfortably handle is still the best option financially.
Consumer credit reform: what changes from 20 November 2026
The transposition of the European directive changes the scope of consumer credit in France from 20 November 2026. Two changes deserve particular attention if you are planning to borrow.
Instalment payments and small loans brought under regulation
Payments in instalments, previously treated as simple payment facilities, will fall under the consumer credit regulatory framework. Lenders will have to assess customers’ creditworthiness, even for small amounts. A simplified regime is planned for certain low-value loans, but the underlying principle is changing: an instalment described as “interest-free” is still a debt added to your other commitments.
This directly affects your budget. Using instalment payments at several different retailers amounts to taking on multiple small loans, whose combined total could push your debt-to-income ratio above the acceptable threshold.
Limit raised to 100,000 euros
The maximum amount for consumer credit will rise from 75,000 to 100,000 euros. Financing that previously fell under a different framework will now benefit from consumer credit protections (a withdrawal period and standardised pre-contractual information).
Repayment difficulties: measures introduced by the reform
The new regulations require lenders to put systems in place to detect financial difficulties. When a borrower shows signs of financial strain, the lender will have to offer suitable solutions.
- Defer instalments to manage a temporary cash-flow problem.
- Restructure the loan term to reduce monthly payments without resorting to debt consolidation.
- Provide guidance on existing support options, including the over-indebtedness procedure managed by the Banque de France.
These measures do not cancel the debt, but they provide some breathing room before the situation worsens. Reporting difficulties early increases your chances of securing revised terms rather than facing an outright rejection.
Choosing a loan comes down to three measurable factors: the APR, the term and the debt-to-income ratio after adding the new monthly payment. A loan whose monthly payment leaves you with comfortable disposable income each month offers better protection than a low rate paired with an excessively long term. When the new rules come into force in late 2026, even small instalment-based loans will count towards this calculation.
