Buying a home is a major financial milestone for many people. For most buyers, the key step to realizing this dream is obtaining a mortgage. Among the various options available, the fixed rate mortgage is one of the most popular choices, as it guarantees a certain stability: the installments remain constant for the entire duration of the loan. However, before signing a mortgage contract, it is essential to understand how to calculate the monthly payment and what factors affect this amount. This calculation is not just a technical matter, but an essential step in determining your repayment capacity and planning your financial future in an informed manner.
Calculating the installment for a fixed rate mortgage requires the analysis of various parameters, including the interest rate, the duration of the loan and the amount of capital disbursed. These elements are essential to avoid unpleasant surprises and ensure that the mortgage chosen is sustainable over time.
What is a fixed rate mortgage
The fixed rate mortgage is a type of financing in which the interest rate applied remains unchanged for the entire duration of the loan. This feature makes it particularly interesting for those who prefer to have a clear and predictable view of their monthly expenses, since the installment will not change over time, regardless of the trend in market rates.
This type of mortgage, therefore, offers greater financial stability, especially in an economic context where interest rates could undergo significant fluctuations. However, compared to other types of mortgages, such as variable rate mortgages, the fixed rate mortgage may initially be more expensive, as starting rates are generally higher.
The parameters to consider for calculating the installment
When calculating the installment of a fixed rate mortgage, three main variables must be taken into consideration: the amount of capital to be repaid, the duration of the loan and the interest rate applied.
- Capital paid: This is the amount that the bank lends to the borrower. Generally, the bank covers a percentage of the value of the property, which varies from 70% to 90%. The capital represents the starting point for calculating the installment, since it is the amount that will have to be repaid.
- Mortgage duration: the duration of the loan directly affects the amount of the installment. A long-term mortgage involves lower installments, but a higher total outlay in terms of interest. On the contrary, a shorter duration leads to higher installments, but a lower overall cost.
- Interest rate: as the name suggests, in the fixed rate mortgage the interest applied remains constant for the entire duration of the loan. This rate represents the “price” you pay for the loan and directly affects the amount of the monthly payment. A higher interest rate translates into a higher payment and vice versa.
How to calculate your mortgage payment
To calculate the installment of a fixed rate mortgage, a formula is generally used that takes into account the capital disbursed, the annual interest rate and the duration of the loan. The formula used by banks to calculate the monthly installment is based on the French amortization method, where the installment is made up of a capital portion and an interest portion.
The mathematical formula for calculating the installment is rather complex, but fortunately today there are numerous online tools that allow you to carry out this calculation in a simple and immediate way.

The relevance of the amortization plan
Once the monthly payment has been calculated, it is important to also understand how the repayment plan works. This plan represents the distribution of the payment of the installments over time, and in particular shows how the composition of the individual installments varies between principal and interest.
In the French repayment plan, which is the most commonly used for mortgages, the interest rate is highest in the first installments and progressively decreases, while the principal amount increases over the years. This means that, in the early stages of the mortgage, you mainly pay interest on the loan, while the part of the principal repaid is relatively low.
Sustainability of the installment
Determining your installment amount is only part of the decision-making process. It is equally important to evaluate your ability to sustain that payment over time, taking into account any changes in income or economic unexpected events. The sustainability of the mortgage does not only depend on the amount of the installment, but also on the stability of personal finances and the performance of the real estate market.
To get a complete picture of your financial situation and make an informed choice, it is advisable to compare different mortgage offers and consider all possible variables, including any additional costs such as notary fees and insurance. With careful planning and the use of the right tools, you can calculate your fixed rate mortgage payment effectively and find the best solution for your financial needs.
