The French credit market operates within a precise regulatory framework, with a debt-to-income ratio capped at 35% by the HCSF and a maximum term of 25 years for home loans. These rules, combined with the recent rise in interest rates, are changing the conditions for accessing finance. Choosing a loan that fits your budget means understanding how these constraints interact with each project.
APR and usury rate: the real filter for a loan application
Most borrowers compare loan offers by looking at the nominal interest rate. This instinct overlooks a mechanism that can block an application before it is even fully reviewed.
The APR (annual percentage rate) combines the nominal interest rate, the cost of borrower insurance and any additional fees. It is this overall rate—not the advertised rate—that the bank compares with the usury rate. A nominal rate that seems acceptable can therefore exceed the cap once all costs are added together.
In practice, two offers with similar nominal rates can have very different APRs depending on the cost of insurance or application fees. Before submitting an application, it may be helpful to understand how this calculation works by consulting A Vos Finances’ credit advice.
Borrowers over 40, whose insurance premiums are mechanically higher, are more likely to come close to the usury threshold. The issue is not their income or down payment, but the weight of insurance in the overall APR.
Debt-to-income ratio capped at 35%: what the rule doesn’t tell you
The HCSF framework sets a maximum debt-to-income ratio of 35% of net income. This standard is often presented as a guarantee: as long as monthly payments remain below this threshold, the loan will be approved.
The reality is more nuanced. Staying within the 35% threshold does not guarantee loan approval. Banks have limited scope to grant exceptions, reserved for a fraction of their lending. An application that meets the debt-to-income limit may still be rejected if the bank has used up its exception quota, or if the disposable income remaining after repayments is considered insufficient.
Disposable income, in particular, is not included in the official debt-to-income calculation. Two households with the same 33% ratio do not have the same financial leeway if one earns €2,500 a month and the other €5,000. Banks factor this into their assessment, though borrowers are not always told about it.
Expenses included in the calculation
- Monthly payments on all existing loans (consumer credit, revolving credit, car leasing) count towards the debt-to-income ratio, even if they are due to end in a few months
- Alimony payments are treated as fixed expenses by most banks
- An unused but still open revolving credit facility may raise questions during the application review because it represents potential borrowing capacity
Repayment term and total cost: the key trade-off
25-year loans are accounting for an increasing share of home lending. Extending the term reduces monthly payments, making it possible to stay within the debt-to-income limit on a more modest income.
The impact on the total cost of the loan is rarely highlighted. A longer loan generates more interest over time, sometimes significantly more. At the same interest rate, the difference between financing over 20 years and over 25 years can mean a substantial additional cost—equivalent to several years of extra monthly payments.
This effect is amplified when interest rates rise. Monthly payments may remain affordable, but the budget actually available for the purchase (and therefore the price of the property you can target) shrinks. For the same monthly payment, purchasing power falls as interest rates rise, even if your salary has not changed.
Home loan or consumer credit: two different approaches
Consumer credit (personal loans, point-of-sale loans or revolving credit) is designed for shorter-term financing needs and smaller amounts. Its interest rate is generally higher than that of a home loan, but the shorter term limits the total interest cost.
A common pitfall is taking out several consumer loans without considering their impact on your overall debt-to-income ratio. A personal loan for a car, revolving credit for household equipment, a store payment plan: each may seem modest on its own. Together, they can prevent you from getting a home loan later.
Comparing loan offers: the factors that can change your decision
Beyond the nominal interest rate and APR, several factors are worth examining before you commit.
- Early repayment fees vary by contract: some banks cap them, while others waive them on fixed-rate loans subject to certain conditions
- Flexible repayment options (the ability to pause or temporarily reduce monthly payments) provide a safety net in the event of an unexpected change in your work or family circumstances
- The cost of borrower insurance can be reduced by taking out a policy with an external insurer, allowing you to compare several policies and lower the APR
- Application and security fees (for a mortgage or guarantee) are often underestimated in the overall financing budget
Comparing two loan offers based solely on the nominal interest rate is like choosing a flight by its advertised price without checking the extras. The APR corrects some of this bias, but it does not tell you about the contract’s flexibility or the terms for early repayment.
A well-prepared loan application starts with a complete inventory of current expenses, a realistic estimate of disposable income after repayments, and simulations across several loan terms. Your purchase budget should be calculated from your constraints, not from the amount you hope to borrow.
