The French Amortization System: How Your Mortgage Works

Note: This system is the standard for mortgages in Spain, France, and Portugal. If you have a mortgage in Continental Europe, you are likely paying it off using the French Amortization System. This differs significantly from systems used in other parts of the world.

How it Works

The defining feature of the French System is the Constant Monthly Payment.

You pay the exact same amount (e.g., €1,000) every month for the entire duration of the loan (assuming a fixed interest rate). However, the composition of that €1,000 changes drastically over time.

The "Interest Trap"

1. Start of Loan: Your debt is high. Therefore, the interest generated is high. Payment 1:* €800 Interest / €200 Principal. 2. Middle of Loan: You have paid off some debt. Interest decreases. Payment 180:* €500 Interest / €500 Principal. 3. End of Loan: Debt is low. Interest is negligible. Payment 360:* €50 Interest / €950 Principal.

This structure means that banks collect their profit upfront. If you sell your house after 10 years of a 30-year mortgage, you will be surprised to see that you haven't paid off much of the actual debt, even though you've made 120 payments.

Strategy: Amortize Early

Because the system is front-loaded with interest, early prepayments (amortizations) are exponentially more valuable.

Paying €5,000 extra in Year 1 saves you 29 years of interest on that amount.

Paying €5,000 extra in Year 29 saves you almost nothing.

Rule of Thumb: Make aggressive extra payments in the first 1/3 of your loan term to destroy the interest curve.

Some key points to consider:

The French Amortization System is designed to prioritize interest payments over principal payments, especially in the early years of the loan.

As a result, borrowers may feel like they're not making progress on paying off their mortgage, even after making regular payments for several years.

However, by making extra payments or prepayments, borrowers can take control of their mortgage and reduce the overall interest paid over the life of the loan.

How to Calculate Your Mortgage Payments

To understand how the French Amortization System works, it's helpful to calculate your mortgage payments. You can use a mortgage calculator or create a custom amortization table to see how your payments will be allocated over time.

Here's an example of how to calculate your mortgage payments:

Determine your loan amount, interest rate, and loan term.

Calculate your monthly payment using a formula or mortgage calculator.

Create an amortization table to see how your payments will be allocated over time.

For example, let's say you have a €200,000 mortgage with a 20-year loan term and a 2.5% interest rate. Your monthly payment might be €1,073.

In the first year, you might pay €8,876 in interest and €2,124 in principal.

In the tenth year, you might pay €4,319 in interest and €6,681 in principal.

In the twentieth year, you might pay €241 in interest and €10,559 in principal.

As you can see, the allocation of your payments changes significantly over time. By making extra payments or prepayments, you can reduce the amount of interest you pay and allocate more of your payments towards the principal.

Benefits of the French Amortization System

While the French Amortization System can be challenging for borrowers to understand, it does offer some benefits:

Predictable payments: With a fixed interest rate, you'll know exactly how much you'll pay each month.

Flexibility: You can make extra payments or prepayments to reduce the interest paid over the life of the loan.

Simple to administer: The French Amortization System is widely used and well-established, making it easy for lenders to administer and for borrowers to understand.

However, there are also some drawbacks to consider:

Front-loaded interest: The system prioritizes interest payments over principal payments, which can make it feel like you're not making progress on paying off your mortgage.

Less transparent: The allocation of payments can be complex and difficult to understand, especially for borrowers who are not familiar with the French Amortization System.

Tips for Borrowers

If you have a mortgage with the French Amortization System, here are some tips to keep in mind:

Make extra payments: Consider making extra payments or prepayments to reduce the interest paid over the life of the loan.

Review your amortization table: Use a mortgage calculator or create a custom amortization table to see how your payments will be allocated over time.

Consider refinancing: If interest rates have fallen or you've improved your credit score, you may be able to refinance your mortgage to a more favorable interest rate.

By understanding how the French Amortization System works and taking control of your mortgage, you can reduce the overall interest paid and achieve your financial goals.

The French Amortization System is a widely used method for calculating mortgage payments in Continental Europe. While it can be challenging to understand, it offers some benefits, including predictable payments and flexibility.
