A mortgage loan is always subject to amortization. This means that, over time, you repay both:
- the capital you have borrowed, and
- the interest owed to the bank for granting the credit.
The way these two elements are distributed over the duration of the loan is determined by your amortization plan.
What Is the Amortization of a Mortgage Loan?
The amortization of a mortgage loan corresponds specifically to the gradual repayment of the borrowed capital. To avoid any confusion, it is important to distinguish the two components of any credit: on one side, the capital requested by the borrower (the amount actually received), and on the other side, the interest paid to the bank in return for the financing granted.
Throughout the life of the loan, each repayment includes a portion of capital and a portion of interest. Depending on the chosen amortization formula, these proportions evolve differently over time. Some solutions prioritize lower monthly payments at the beginning, while others help you reduce the overall cost of your credit more quickly.
In certain situations, the amortization of a mortgage loan may allow you to benefit from tax deductions, subject to specific legal and fiscal conditions applicable in 2026. It is highly recommended to inquire about these rules and, if necessary, consult a specialist to make sure you make the most of any potential tax advantages.
Good to Know
The amortization method you choose will influence your monthly budget, the duration of your mortgage loan, and the total amount of interest paid. A well‑designed plan is a key lever to optimize the cost of your real estate project.
What Is a Mortgage Amortization Plan?
When you sign a real estate credit contract, such as real estate solutions, the financial institution and the borrower agree on a repayment plan. This document details the main characteristics of the loan: the amount borrowed, the interest rate, the duration, and especially the structure of each monthly payment.
On this basis, a detailed amortization schedule is drawn up. This schedule specifies, month by month, how the loan will be repaid, indicating for each installment:
- the part of the payment corresponding to the repayment of the capital,
- the part representing the interest,
- the remaining balance of capital still to be repaid after each monthly payment.
The amortization plan is therefore a real roadmap for your mortgage loan. It allows you to anticipate the evolution of your monthly payments, visualize the outstanding balance at any time, and better plan your budget throughout the term of your real estate financing.
The Different Types of Mortgage Loan Amortization
There are several possible amortization structures for a mortgage loan. Each has its own logic and consequences on the level of your monthly installments and the total cost of the credit. Understanding these options will help you choose a formula that matches your current situation and your future plans.
Constant Monthly Payments
With this formula, you repay your mortgage loan through regular, constant monthly payments over the entire duration of the contract. The overall amount of each installment remains the same (subject to any rate changes if the loan is variable).
At the start of the loan, the interest share is higher than the capital share. As time goes by, this trend reverses: the portion of capital increases while the interest portion decreases. This solution offers good visibility and facilitates budgeting thanks to the stability of monthly outgoings.
Interest-Only During the Term
In this structure, the mortgage loan is amortized by repaying only the interest throughout the agreed duration. The capital is not reduced during this period and remains due in full at the end of the contract.
At maturity, the borrower repays the entire borrowed capital in a single payment, along with the interest corresponding to the final monthly installment. This solution can temporarily ease the monthly burden but requires a solid strategy (savings, investment, resale of a property, etc.) to be able to settle the capital when the loan ends.
Fixed Capital Repayment
A third alternative consists of repaying a fixed amount of capital in each monthly payment. The capital portion is calculated by dividing the total borrowed amount by the number of months of amortization.
Since the outstanding capital decreases at a steady pace, the interest is paid on a declining basis, which means that your monthly payments gradually decrease over time. This formula usually reduces the total cost of the loan but leads to higher installments at the beginning of the contract.
Which Amortization Solution Should You Choose?
Choosing the most suitable amortization method for your mortgage loan is never a trivial decision. The right solution will depend on several key factors: the total amount borrowed, the duration of your credit, your current and future income, your savings capacity, and your long‑term projects (renovation, investment, early repayment, etc.).
Some borrowers will prioritize stability and predictability with constant monthly payments, while others may look for flexibility at the beginning of the loan with an interest‑only formula, or a faster reduction of their debt by opting for fixed capital repayments. Each option presents advantages and constraints that must be assessed in relation to your personal and family situation.
To make an informed choice and avoid costly mistakes, it is always preferable to consult a mortgage specialist. An expert can simulate different amortization scenarios, compare the total cost of each formula, and help you select the repayment plan that best protects your budget while supporting your projects in 2026.
