A student who secures a place in a business or engineering school faces a wall: rising tuition fees, rent to pay upfront, and equipment to buy. The reflex is to look for a traditional student loan, but rates often range between 0.99% and 3.5% APR depending on the institutions.
The zero-interest student loan exists, but it remains concentrated in a few specific banking networks, with limited envelopes. Understanding where to submit your application, and especially when, makes all the difference.

Zero-interest student loan: which banks really offer it
On paper, many banks advertise “student loan” offers. In practice, the true 0% APR remains rare and targeted. In 2026, Crédit Mutuel and CIC are virtually the only networks offering a structurally 0% APR student loan, for amounts up to 50,000 euros. This zero rate is not automatic: it depends on the family’s income quotient and requires a guarantor.
Other banks (Crédit Agricole, Société Générale, Banque Populaire, etc.) offer student loans, but at rates that generally start around 0.99% and can go much higher. So when we talk about a zero rate, we are not referring to a widespread offer. It is a promotional product reserved for a specific profile, within a specific network.

To find out how to obtain a zero-interest student loan, you first need to check if you meet the family income quotient criteria required by CIC or Crédit Mutuel, then make an appointment with a representative from the relevant regional bank. The envelopes are limited in volume and time, meaning that an application submitted in September has less chance of success than one submitted in June.
State-guaranteed student loan: an alternative without parental guarantee
The state-guaranteed student loan (PEGE) is often confused with the zero-interest loan, but they are not the same. The PEGE allows you to borrow without providing a guarantee from a relative or proof of income, because the state guarantees it through Bpifrance. The rate is freely set by the partner bank.
The eligibility criteria are clear:
- Be under 28 years old at the time of subscription (or emancipated minor).
- Be of French nationality, a citizen of the EU or the European Economic Area.
- Be enrolled in an institution preparing for a diploma, certification, or competitive exam of the French higher education system.
The maximum amount of the PEGE can reach 20,000 euros, with a minimum repayment period of two years. The borrower can choose a total or partial repayment deferral, meaning they only start repaying the principal (and sometimes the interest) after finishing their studies.
Total or partial deferral: what it really changes
With a total deferral, you pay nothing during the study period, neither principal nor interest. The total cost of the loan will be higher in the end, because interest accrues and compounds. With a partial deferral, you pay interest each month during your studies, but not the principal. The monthly payment remains low (often just a few dozen euros), and the final cost of the loan decreases.
The choice between the two depends on the ability to allocate even a small monthly budget during studies. Feedback varies on this point: some part-time working students prefer the partial deferral to limit the final bill, while others simply cannot afford to pay anything before their first job.
Student loan application: documents to prepare and common mistakes
The time required to prepare the application is often underestimated. For a student loan, whether it is zero-interest or state-guaranteed, the bank requires a complete application before even discussing the rate. Here are the documents to gather:
- Valid ID and recent proof of residence.
- Enrollment certificate or admission letter from the higher education institution.
- Bank statements for the last three months (yours, or your parents’ if you are financially dependent).
- If applicable, the tax notice of the household (for offers related to the family income quotient).
The most common mistake is showing up at the bank without an enrollment certificate. Many students receive their admission via Parcoursup or Mon Master late, and the bank cannot process the application without this document. Anticipating by requesting a provisional certificate from the institution can save several weeks.
Timing of the application: why applying early makes a difference
The envelopes for zero-interest student loans are distributed by regional banks, and when the envelope is exhausted, the offer disappears. Submitting your application between May and July, as soon as admission is confirmed, maximizes the chances of obtaining the promotional rate. Waiting until September means risking facing a standard rate, even at a bank that previously offered 0%.
Borrower insurance and student loan: mandatory or optional
The student loan is a consumer loan. As such, borrower insurance is not legally mandatory. The bank may offer it, or even insist on it, but it cannot condition the granting of the loan on the subscription of insurance.
For a healthy student, the cost of insurance may seem negligible. On a loan of several tens of thousands of euros repaid over five to ten years, the monthly premium accumulates. Comparing the total cost of the loan with and without insurance, by requesting a detailed simulation from the advisor, allows for an informed decision rather than just ticking the “yes” box.
The zero-interest student loan remains a niche product, distributed by a few banking networks with envelopes that run out quickly. The PEGE offers a safety net for those without family guarantees, but its rate is not zero. In both cases, the key is to prepare your application early, with the right documents, and to compare offers before signing.
