Mortgage Calculator 2025: Amortization & Savings - Free Tool

A mortgage is more than a monthly payment. With our mortgage simulator, you can see the full breakdown of your payments, interest, and remaining capital.

The tool generates a detailed amortization table so you understand where every cent goes. Easily compare the French system (constant payments) with the German system (constant capital) and choose the one that suits you best.

What if you could pay off your mortgage early? Making early repayments is key. Simulate extra payments and instantly see how you can reduce your loan term or lower your monthly payment, saving thousands in interest!

Amortization Systems: French vs. German

The choice of amortization system defines how you will return the money to the bank. The most common in Spain are:

  • 🇫🇷 French System (Constant Fee)

    You will pay the same fee every month. At the beginning, most of the fee goes to paying interest. As the years go by, this proportion changes and you amortize more capital. It is the most used for its predictability.

  • 🇩🇪 German System (Constant Capital)

    The part of the fee that is destined to return the capital is always the same. As the outstanding capital decreases, the interest does too, so the monthly fee is decreasing. You will pay less interest in total than with the French system.


The Key Strategy: Early Amortization

Making extra payments on your mortgage is one of the smartest financial decisions. When doing so, you have two options:

1. Reduce the Term

You keep the same monthly fee but finish paying the mortgage earlier. This option is usually the one that saves you the most interest in the long run. Ideal if your goal is to clear the debt as soon as possible.

2. Reduce the Fee

You keep the original term but your monthly payments are reduced. This option gives you more economic leeway in your day to day. Ideal if you are looking to improve your monthly cash flow.

Our calculator allows you to simulate both scenarios so you can see the real impact of each prepayment and make the best decision.


Frequently Asked Questions (FAQ)

The TIN (Nominal Interest Rate) is the 'price' of the money. The APR (Annual Percentage Rate) is the REAL cost, as it adds the TIN + opening fees + mandatory insurance + expenses. To compare mortgages, always look at the APR.

It is the most used reference index for variable mortgages in Spain. If your mortgage is variable (Euribor + Spread) and the Euribor goes up, your payment goes up. If it goes down, your payment goes down.

We use the French method (the standard in Spain). It calculates what part of your payment pays interest and what part repays debt. At the beginning, you pay a lot of interest and little capital; at the end, it's the other way around.

Frequently Asked Technical Questions

What is the difference between the French and German systems?

The French system maintains constant installments throughout the loan (paying more interest at first), while the German system amortizes the same amount of principal each month, resulting in decreasing installments.
