Getting credit quickly does not exempt one from structuring their file. Most refusals or unfavorable conditions stem from technical errors that the borrower could have corrected beforehand. Here are the five most common mistakes, ranked by their impact on the processing of the file.
1. Not checking borrowing capacity before applying for credit
Submitting a loan application without calculating one’s actual debt ratio is akin to inviting a refusal. Lenders apply a threshold of monthly charges relative to net income. Exceeding this threshold, even slightly, triggers an automated rejection before any human analysis of the file.
The calculation is not limited to net salary. Alimony payments, ongoing revolving credits, car leasing installments: every recurring financial commitment counts. We recommend creating a complete list of fixed charges before any simulation.
On the Terre Finance credit site, simulators allow you to cross-reference income and charges to estimate the maximum manageable monthly payment. This type of verification takes a few minutes and prevents unnecessarily burning an application, as each refusal leaves a mark in the files consulted by lenders.
2. Neglecting to compare available credit offers
Accepting the first proposal received can be costly. The difference in the annual percentage rate (APR) between two credit organizations, for the same borrower profile and amount, can represent several hundred euros over the total duration of the personal loan.
The comparison is not solely about the nominal rate. Three parameters truly distinguish the offers:
- The APR (annual percentage rate), which incorporates application fees, optional borrower insurance, and ancillary costs into a single indicator
- The conditions for early repayment, particularly the presence or absence of penalties for early repayment
- The flexibility of monthly payments, meaning the ability to defer or increase a payment without an amendment to the contract
A revolving credit advertised at a low rate may turn out to be more expensive than a classic personal loan at a higher rate, simply because the effective repayment duration lengthens with successive withdrawals. We regularly observe this trap among borrowers who confuse ease of subscription with the total cost of financing.
3. Having a poor credit history or an incomplete file
A payment incident recorded in the personal credit repayment incident file (FICP) blocks nearly all applications. The removal is not immediate after rectification: the retention period can last several years depending on the nature of the incident.
An incomplete file produces a comparable effect. An expired proof of residence, a truncated bank statement, or the absence of a tax notice is enough to delay processing or even trigger a refusal due to missing documents within the allotted time. Credit organizations have no obligation to follow up with the borrower.
Submitting a complete file from the first application significantly shortens the processing time. A valid ID, the last three pay slips, the latest tax notice, and bank statements from the last three months: this list covers most requirements.
4. Borrowing without understanding the conditions and hidden fees
The European directive on consumer credit mandates a standardized pre-contractual information sheet. From November 20, 2026, all credit operations up to 100,000 euros will fall under the Consumer Code, including installment payments, mini-loans, and leases with an option to buy.
This reform is not trivial. It means that solutions currently presented as simple payment facilities will be subject to mandatory solvency analysis, the right of withdrawal, and advertising regulation. The statement “Warning, credit costs money and must be repaid” will become systematic, including for payments in three or four installments.
In practical terms, the fees to check before signing remain the same:
- Application fees, sometimes negotiable, sometimes flat-rate and non-refundable in case of early repayment
- The cost of borrower insurance, often presented as optional but included by default in the initial simulation
- The late penalties, which apply from the first day of exceeding the due date
5. Requesting credit for an amount that is too high
Borrowing at the maximum of one’s theoretical capacity eliminates any margin for maneuver. An unforeseen event (loss of bonus, car repair, change in family situation) can turn a manageable loan into a financial strain from the first months.
Lenders assess the “remaining disposable income” after deducting charges and the new monthly payment. A requested amount that is too high relative to declared income does not always trigger a refusal: it can lead to a counter-offer at a higher rate, as the perceived risk by the organization directly impacts the cost of credit.
We recommend calibrating the borrowed amount to the actual need, not the maximum allowable. A properly sized loan, repaid without strain, builds a positive history that will facilitate future applications. Conversely, multiplying requests for high amounts after an initial refusal degrades the credit score consulted by financing organizations.
The regulatory framework coming into effect at the end of 2026 will further strengthen solvency analysis across all consumer credit. Preparing a solid file, comparing offers based on the APR, and adjusting the amount to the actual need remain the three concrete levers for obtaining a personal loan under good conditions.
