Frequently asked questions
What is the French amortization system?
It is the most common mortgage repayment method. The monthly payment stays fixed throughout the loan. Initially, a larger portion goes toward interest and less toward principal, but this ratio gradually reverses over time.
How much salary do I need for a mortgage?
Banks recommend that your mortgage payment should not exceed 30-35% of your net monthly income. This calculator uses 30% as the reference to determine the minimum required salary.
How does the interest rate affect my mortgage?
Each percentage point difference in the interest rate can mean thousands in additional interest paid. For example, on a 150,000 mortgage over 25 years, going from 2.5% to 3.5% results in roughly 25,000 more in total interest.
