Early mortgage repayment: fees, legal limits and how to do it

Updated: July 12, 2026

Early repayment means paying back part (or all) of your mortgage principal ahead of schedule. It is one of the most profitable financial decisions the average mortgage holder can make: every euro repaid early stops generating interest for all the years that still lay ahead.

What the law says: capped fees

Since Ley 5/2019 de Contratos de Crédito Inmobiliario (LCCI, Spain’s mortgage credit law), the early repayment fee is capped by law and can only be charged if the bank proves that your repayment causes it a financial loss:

Type of mortgage Maximum fee
Variable (option A) 0.25% of the principal repaid, only during the first 3 years
Variable (option B) 0.15% of the principal repaid, only during the first 5 years
Variable, after that period 0%
Fixed, during the first 10 years 2% of the principal repaid
Fixed, from year 11 onwards 1.5%

In practice, at current rates many early repayments cause the bank no financial loss, and the effective fee is zero. Check your mortgage deed: mortgages signed before June 2019 are governed by whatever was agreed in it.

How to do it, step by step

  1. Notify your bank (online banking, phone or branch) that you want to make a partial early repayment and for what amount.
  2. Choose what to reduce: the monthly payment or the term. It is the key decision and we analyze it in depth in reduce the payment or the term?.
  3. Sign the order. The bank recalculates the amortization schedule and gives you a receipt showing the new outstanding principal.

You do not need a notary for partial repayments; only full early cancellation with the release of the mortgage charge requires a deed and registration.

When it pays off (and when it doesn’t)

  • It pays off most at the beginning. With the French amortization system, during the first years of the mortgage you mostly pay interest: that is when every euro repaid early saves the most. You can check it by simulating two scenarios in the calculator below.
  • It pays off more the higher your interest rate. Repaying a mortgage at 4% is like “investing” with a guaranteed 4% return; at 1.5%, your money might earn more elsewhere.
  • Don’t drain your savings. Always keep an emergency fund (3-6 months of expenses) before handing money to the bank ahead of schedule.
  • Mind the old tax rules: if you bought before 2013 and apply the main-residence deduction, repaying up to €9,040 per year also gets you 15% back on your income tax return.

Early repayment and mortgage type

In a variable-rate mortgage, repaying early reduces your exposure to the Euribor: less outstanding principal means each rise in the index hurts less (you can measure it on our Euribor page). In a fixed-rate mortgage, the saving is exact and predictable from day one. And if your strategy is to repay heavily during the first few years, a mixed mortgage may suit you particularly well.

Frequently asked questions

What fee can I be charged for repaying early?

On variable-rate mortgages, at most 0.25% of the amount repaid during the first 3 years or 0.15% during the first 5 (depending on what was agreed), and 0% afterwards. On fixed-rate mortgages, up to 2% during the first 10 years and 1.5% afterwards. And only if the bank proves it suffers a financial loss.

Is it better to repay my mortgage early or invest the money?

It depends on your mortgage's interest rate and the return you can obtain without risk. As a quick reference: repaying early is equivalent to a guaranteed return equal to the loan's interest rate. With high interest rates, early repayment becomes more attractive; with very low rates, investing may pay off more.

How much money can I repay in one go?

There is no legal limit: you can repay anything from small amounts up to the entire loan (early cancellation). Some banks require a minimum amount per transaction; check your mortgage deed.

Is early repayment deductible on my income tax return?

Only if your main residence was bought before 1 January 2013 and you were already applying the main-residence investment deduction: in that case, the amounts repaid are added to the deduction base (15% up to €9,040 per year). For later purchases there is no state deduction.
