A bank loan is a contract by which a lending institution provides a sum of money to a borrower, who repays it according to a defined schedule, plus interest. This simple mechanism comes in several types of loans, each serving a specific purpose: financing a home, equipping a household, starting a business, or covering a temporary cash flow need.
Fixed rate vs variable rate: the parameter that changes everything in a loan
Before comparing loan categories, one concept deserves to be established: the type of rate. In France, almost all mortgage loans are taken out at a fixed rate, unlike in other European countries where variable rates remain common. This choice is not trivial: a fixed rate guarantees stable monthly payments throughout the duration of the contract, while a variable rate follows a reference index and can increase or decrease.

For a long-term loan, the fixed rate offers budgetary visibility that is difficult to obtain otherwise. The variable rate, on the other hand, can be relevant for short durations or in a context of prolonged decreases in benchmark rates. Most French banks default to a fixed rate for mortgage loans, and this trend has strengthened in recent years.
Before choosing between consumer credit, mortgage loans, or professional financing, it is therefore useful to consult credit on Crédit et Immobilier to compare the rate mechanisms associated with each loan type.

Mortgage loans: amortizable loan, in fine loan, and bridge loan
The amortizable loan remains the most common form of mortgage loan. Each monthly payment includes a portion of capital and a portion of interest. Over time, the share allocated to capital increases while that of interest decreases. This mechanism allows for a gradual reduction of the outstanding amount.
The in fine loan works differently: the borrower only repays the interest throughout the loan term, then settles the capital in one lump sum at the final payment. This arrangement is primarily aimed at rental investors, as the interest, which is deductible from rental income, can lighten the tax burden. It assumes having sufficient savings to repay the capital at maturity.
The bridge loan covers a very specific need: buying a new home before selling the previous one. The bank advances a fraction of the estimated value of the property for sale. The duration rarely exceeds two years. If the sale is delayed, the situation can become financially tense.
Assisted loans and combined arrangements for a property purchase
Several public schemes complement traditional bank financing. The zero-interest loan (PTZ), reserved for first-time buyers under certain income conditions, allows financing part of the project without paying interest. The social accession loan (PAS) and the regulated loan are aimed at modest households and entitle them to personalized housing assistance.
Combining a main loan with one or more assisted loans reduces the overall cost of financing. However, banks check the coherence of the entire package: debt ratio, remaining living expenses, personal contribution. A too complex arrangement without a safety margin can weaken the borrower in case of unforeseen events.
Consumer credit: earmarked, personal, and revolving
Consumer credit covers needs that do not relate to real estate. Three forms stand out by their degree of freedom of use:
- The earmarked credit finances a specific purchase (vehicle, appliances, renovations). The contract mentions the item concerned, and if the sale is canceled, the credit is also canceled. This protection represents a concrete advantage for the borrower.
- The personal loan provides a freely usable amount. The borrower does not have to justify their expenses to the bank. The rate is generally fixed, with predictable monthly payments.
- The revolving credit allows a reserve of money to be used in full or in parts. Flexibility is maximum, but the rates applied to revolving credit are significantly higher than those on a standard personal loan. This type of credit can lead to progressive indebtedness if repayments only cover the interest.
The European directive 2023/2225, adopted in October 2023, strengthens the information obligations of lenders towards consumers, particularly for online distribution. Its transposition into French law will more strictly regulate certain commercial practices related to consumer credit.

Professional credit and cash flow financing
Businesses access forms of credit tailored to their activity cycles. The classic professional loan finances a specific investment: purchase of equipment, fitting out premises, commercial development. The bank analyzes the balance sheet, forecasts, and the company’s repayment capacity.
Cash flow financing addresses a different need. It covers temporary gaps between receipts and payments. Common tools include cash facilities, authorized overdrafts, or factoring (selling receivables to a third-party organization).
Leasing and rental with option to purchase
Leasing, whether in the form of a LOA (rental with option to purchase) or a LLD (long-term rental), is not a loan in the strict sense. The borrower does not own the asset during the contract term. The LOA offers the possibility to purchase the asset at the end of the term, while the LLD does not provide for this. These arrangements appeal to professionals who prefer not to tie up capital.
Debt consolidation: grouping to reduce monthly payments
Debt consolidation involves having several ongoing loans bought out by a single institution, which replaces them with a single loan. The overall monthly payment decreases, which improves the remaining disposable income. The trade-off is often an extension of the repayment period, and therefore a higher total interest cost.
This mechanism is aimed at borrowers who have multiple consumer loans or who combine mortgage loans and personal loans. Debt consolidation does not erase the debt, it reorganizes it. Before committing, comparing the total cost before and after consolidation remains the only way to evaluate the operation.
Each type of loan responds to its own logic: duration, rate, allocation of funds, required guarantees. The choice depends on the project, financial profile, and ability to absorb the monthly payments over the planned duration. Checking the conditions for early repayment, often overlooked at signing, can avoid significant fees in case of a change in situation.
