Financial loss due to Early Mortgage Repayment
Paying off or repaying a mortgage early is a common decision among those who wish to reduce debt, shorten terms, or definitively cancel their loan. However, it is not always a neutral operation from an economic point of view, as in certain cases the financial institution may require compensation for financial loss on mortgages.
Since the entry into force of Law 5/2019, regulating real estate credit contracts, the regime applicable to early repayment has been subject to stricter rules, aimed at enhancing transparency and limiting the costs that can be imposed on the borrower. Even so, it remains a technically complex matter, where financial concepts — such as present value, the spread or the IRS — converge with legal limits that are not always correctly interpreted.
Even before considering paying off the loan early, it is advisable to be well aware of the loan conditions and their economic implications, something we have already analysed in detail in our article on what questions should be asked before taking out a mortgage.
Return to the bank the outstanding mortgage principal
Early repayment consists of returning to the bank, before the agreed maturity date, part or all of the outstanding capital of the mortgage loan. It is a common possibility in practice, provided for in most mortgage contracts and closely linked to the legal regime of mortgages.
As we explained in another article, it can take two forms: partial or total.
You can learn more about the types here:
In both cases, the borrower reduces future interest. However, this reduction may mean, from the financial institution's perspective, foregoing an initially expected return, which leads to the concept of financial loss.
What is financial loss and why is it not an automatic penalty?
Concept of financial loss
The financial loss is the real economic damage that the financial institution may suffer when the loan is repaid early and the bank cannot reinvest the returned capital under conditions equivalent to those agreed in the operation.
It is not a sanction nor a hidden penalty. The compensation is only legitimate when, from an objective economic point of view, the market value of the loan is reduced as a consequence of the early repayment.
Not all early repayments generate financial loss
This nuance is fundamental.
If the bank can reinvest the capital repaid early at an interest rate equal to or higher than that generated by the loan, there is no financial loss, and consequently no compensation can be demanded, even if the contract includes a maximum percentage.
Precisely for this reason, before deciding to repay early, it is advisable to analyse whether an actual saving will really be made.
The IRS in financial loss: market type and non-discretionary choice of the bank
The IRS as a mandatory reference type
The IRS (Interest Rate Swap) is the interest rate that reflects the cost of swapping a fixed rate for a variable one in the wholesale market for a given term. In the context of financial loss, the IRS is not an index that the bank can freely choose, but rather a target market rate, officially published by the Bank of Spain. Here is the link from the Bank of Spain where you can check this index by months and years.
This implies that:
- the entity cannot apply the IRS that suits it best,
- the IRS corresponding to the term that most closely matches the relevant period of the loan must be used,
- and this rate must be verifiable, objective and explainable to the borrower.
The relevant differential in the financial loss
The differential taken into account is not the commercial differential of a variable mortgage (Euribor + X). It is the economic differential existing at the time of contracting the loan between:
- the interest rate agreed in the operation, and
- the IRS corresponding to the term that most closely approximates, at that moment,
until the date of the next interest rate review, or
until the loan maturity date, if this is earlier.
This initial differential is the one that is economically projected to determine whether, upon early repayment, a real financial loss occurs or not.
How is financial loss actually calculated?
The financial loss is calculated by comparing the market value of the loan before and after the early repayment. For this, the financial concept of present value is used, applying as the discount rate the market rate (IRS) corresponding to the relevant term.
Calculation of the present market value of the loan
The present market value of the loan is obtained as the sum of two values:
- The current value of the instalments pending payment until the date of the next interest rate review, and
- The current value of the outstanding principal that would remain at the time of said review, assuming that no early repayment had been made.
Both values are calculated by applying the market interest rate corresponding to the remaining term until the next review.
What is the formula applied to financial loss?
In summary:
Financial loss = Outstanding capital − Present Value (PV) of the loan market
Where the Present Value (PV) is expressed as follows:
This methodology allows reflecting the real economic value of the loan in the market, and it is the one used by financial institutions in their calculation models.
Practical example: why is the financial loss not a percentage?
One of the most common confusions when talking about early mortgage repayment is thinking that the financial loss is expressed as a percentage. In reality, this is incorrect.
The financial loss is always calculated in euros, while the percentages provided in the regulations function only as maximum legal limits on the compensation that the entity can demand.
This error is frequent because, in banking practice, only the applicable percentage is usually communicated, without explaining the prior economic calculation. Let us see a complete example to understand it correctly.
Data of the case
- Outstanding mortgage principal: €150,000
- Loan interest rate: 3.00%
- Next interest rate review: in 2 years
- IRS applicable to the term until the review: 1.85%
Step 1: calculation of the actual financial loss (amount in euros)
To determine if there is a financial loss in an early repayment, it is necessary to calculate the market present value of the loan, using the IRS as the discount rate, which is the published market rate applicable to the corresponding term.
According to common practice and the mortgage models used by entities, the present value of the loan is obtained by adding:
- The current value of the instalments that would be paid until the next interest rate review.
- The current value of the outstanding principal that would remain at that time if the early repayment did not occur.
Both amounts are financially discounted using the IRS for the remaining term until the review.
Let us suppose that, after performing this calculation, the market present value of the loan amounts to €147,800.
The actual financial loss would then be:
€150,000 − €147,800 = €2,200
This is the financial loss, and it is always expressed in euros, not as a percentage.
Step 2: application of the legal limit in percentage
Law 5/2019 establishes that the compensation for early repayment cannot exceed a certain percentage of the repaid capital, depending on the type of mortgage and the moment when the repayment takes place.
Let us suppose that, in this case, the applicable legal limit is 2%.
- 2% of €150,000 = €3,000
This percentage does not represent the financial loss, but rather the maximum legal amount that could be charged, even if the actual loss were higher.
Correct result
In this example, two different figures concur:
- Actual financial loss: €2,200
- Maximum legal limit (percentage): €3,000
The bank could only charge €2,200, because the compensation:
- can never exceed the actual financial loss,
- even if the legal percentage allows a higher amount.
If the opposite occurred — for example, an actual financial loss of €4,000 — the entity could only charge €3,000, since the percentage acts as a legal ceiling.
Why is there so much confusion about financial loss?
The belief that “the financial loss is a percentage” is due to the fact that:
- entities usually only communicate the applicable percentage,
- they do not explain the calculation of the present value nor the role of the IRS,
- and the legal limit is confused with the real economic loss.
It is worth emphasising this key idea:
The financial loss is calculated in euros; the percentage only limits what the bank can charge.
Legal limits on compensation for financial loss
Law 5/2019 establishes maximum limits that act as a legal ceiling in its article 23, in its paragraphs 5 (for variable interest) and 7 (for fixed interest):
|
Type of mortgage |
Period |
Maximum limit |
|
Variable |
First 5 years |
0.15 % |
|
Variable |
First 3 years (alternative) |
0.25 % |
|
Fixed |
First 10 years |
2 % |
|
Fixed |
Rest of the term |
1.5 % |
These limits do not automatically legitimise the charge, but only operate when there is a real and correctly calculated financial loss.
What should you always check?
Before making an early repayment or proceeding with the cancellation of the mortgage, it is advisable to:
- identify the IRS used and its official publication,
- verify the reference period applied,
- review the calculation of the present value,
- check that the compensation does not exceed either the actual loss or the legal limit.
Conclusion: amortise with criteria and legal certainty
Early repayment can be an excellent financial decision, but only when it is made with a clear understanding of how the financial loss is calculated and of which parameters must be correctly applied.
The IRS, as an officially published market rate linked to the relevant loan term, is the central element of the calculation. Without a correct identification of the applicable IRS and without a consistent financial update, it cannot be said that there is a real financial loss.
In notarial practice, and especially in routine transactions in a notary office in Barcelona, such as those formalised in areas with high real estate activity —Eixample, Avenida Diagonal or the area around Passeig de Gràcia—, it is essential that these matters are clearly understood before repaying or cancelling a mortgage. The Notary, as guarantor of transparency and legal certainty, plays a key role in helping these decisions to be made with full knowledge of their economic and legal consequences.
Frequently Asked Questions (FAQs)
Yes. The law sets limits and requires that the loss be real and verifiable.
No. You must use a type of target market, officially published and consistent with the applicable term.
No. Only when the market value of the loan is reduced as a consequence of the amortisation.
In addition to the financial institution, the notary can help verify the economic and legal consistency of the calculation.
