(1) To calculate the Variable APR, the amount of the installments, the total cost of the loan, and the total amount owed, the initial fixed rate for the first year of 2,50% and the rate of 3,85% for the remaining periods have been taken into account (sum of the 1-year Euribor 3,247% according to the reference published in the BOE dated 02-10-2026 + the margin of 0,60%), since the initial fixed rate is not higher than the variable period rate.

(2) To calculate the Variable APR, the amount of the installments, the total cost of the loan, and the total amount owed, the initial fixed rate for the first year of 3,50% and the rate of 4,85% (sum of the 1-year Euribor 3,247% according to the reference published in the BOE dated 02-10-2026 + the margin of 1,60%) have been taken into account, since the initial fixed rate is not higher than the variable period rate.

(3) The amortization system for this mortgage loan is the EPC (French or constant installment). The monthly installment (C) is calculated using the following formula:

C = P * (i / (1 - (1 + i)-n)).

Where "P" is the outstanding principal of the loan; "i" is the interest rate, which is the result of dividing the annual nominal interest rate (TIN) by 12 (number of installments per year); and "n" is the number of installments remaining on the loan. The installment amount is rounded to the second decimal place. The monthly installment consists of principal repayment (the part used to repay the borrowed money) and interest (the part that remunerates the outstanding principal).

To calculate the interest "I" of each installment, the following formula is used:

I = P * i.

Where "P" is the outstanding principal of the loan; and "i" is the interest rate, which is the result of dividing the annual nominal interest rate (TIN) by 12 (number of installments per year). The interest amount is rounded to the second decimal place.

To calculate the amount corresponding to the principal repayment "A", subtract the interest amount "I" from the installment "C"; using the formula:

A = C - I.

Do you want to know how we calculated the Variable APR in this representative example?

For the calculation of the Variable APR, both with and without bonuses, the commitments and costs borne by the borrower shown in the following table have been included. In the case of the maximum bonus, the calculation assumes that you will keep the following products contracted with ABANCA for the entire duration of the mortgage.

and annual renewal 350,66 € (9)

(4) Since ABANCA does not offer damage insurance that only covers the risks indicated by mortgage market regulations, to calculate the cost of such a product, a home insurance policy has been simulated (which is the closest equivalent to damage insurance, but includes broader coverage). This amount is for guidance purposes only. In accordance with mortgage market regulations, in order to take out this loan, it is required to maintain damage insurance for the entire life of the mortgage. It is not mandatory to take it out with ABANCA; you may contract it with an insurance company of your choice; however, you will only be eligible for the 0.20% differential discount if you take it out through ABANCA and link it to the mortgage.

(5) Home insurance for the mortgaged property with coverage of €150,000 for the building and €12,000 for contents (in the event of a claim, the compensation will correspond to the real value of the asset).

(6) The interest rate reduction for direct deposit of salary will also apply to any recurring income, as long as the minimum required amounts are met.

(7) Taking out a payment protection insurance policy associated with the mortgage that covers 100% of the outstanding balance (maximum contracting age 64 years and 6 months, and maximum renewal age 66 years and 6 months). The contracting terms may be: annual renewal, or a single premium for the first 5 years and, from year 6 onwards, annual renewal until the end of the operation. In our representative example, and for informational purposes, a single premium payment protection insurance is simulated for the first 5 years of 3.260,72€, and from year 6 onwards with annual renewal at a premium of 720€.

(8) Contracting and maintaining an alarm system marketed through the ENTITY and provided by Sector Alarm, as long as the fees for this service are direct debited (and not returned) from an account opened in the ENTITY in the name of one of the borrowers.

(9) Taking out a life insurance policy marketed through ABANCA (maximum contracting age 65 years and 6 months, and maximum renewal age 69 years and 6 months) associated with the loan. The contracting terms for the life insurance associated with the mortgage may be: (i) annual renewal, or (ii) single premium for 6, 8, or 10 years. For informational purposes, an annually renewable life insurance policy is simulated with an estimated premium of 350,66€ for a 30-year-old borrower, which remains constant throughout the life of the operation; since it is complex to determine the cost of the insurance at each renewal, as it may vary depending on multiple circumstances (age, outstanding loan balance, applicable taxes, borrower's health status, etc…)

If the borrower is unable to take out the indicated insurance policies or, during the term of the loan, exceeds the indicated age limits, they may obtain the maximum discount by contracting the alternative products previously indicated, which compensate for the interest rate reduction not applied by the insurance policies. The Variable APR will be modified compared to the simulated one, as the costs of the premiums for the non-contracted insurance policies and the applicable discount for such insurance will not be taken into account, but rather the costs and discounts corresponding to the chosen substitute products.

The Borrower must keep an account open with ABANCA, until the loan is repaid, associated with the loan, into which the loan amount will be paid and from which the payments required under this contract will be debited.

The Variable APR with and without discount has been calculated under the assumptions that: (i) the loan contract for the indicated amount will remain in force for the entire agreed duration, (ii) the ENTITY and the Borrower will fulfill their obligations under the agreed conditions and deadlines, so commissions and expenses that the Borrower may avoid if they fulfill their contractual obligations have not been included, (iii) the interest rate, commissions, and expenses remain at the level set in the initial period throughout the term of the contract, (iv) no total or partial repayment occurs during the entire duration of the loan, and (v) the reference indices do not change; therefore, this Variable APR will change with interest rate reviews. The Variable APR with discount may also vary due to the application of discounts.

To obtain the indicated discount, the insurance policies must necessarily be marketed by the intermediary: ABANCA MEDIACIÓN, OPERADOR DE BANCA-SEGUROS VINCULADO, S.L., a tied bancassurance operator, with registered office at Avenida de la Marina nº 1, 4th floor, A Coruña, registered in the Commercial Registry of A Coruña, volume 3321, folio 64, sheet C-38698 and in the Special Administrative Register of Insurance Intermediaries of the Directorate General of Insurance and Pension Funds with number OV-0044 and with Tax ID: B-70049630. With Civil Liability Insurance and Financial Capacity as required by current insurance distribution regulations. Available insurance companies can be found in the Insurance section of abanca.com.

The following costs borne by ABANCA have not been included in the calculation of the Variable APR:

(i) execution of the mortgage loan deed at the Notary,

(ii) registration of the mortgage loan deed in the Land Registry,

(iii) management fees related to the execution at the Notary and registration of the mortgage loan in the corresponding Land Registry,

(iv) payment of the IAJD; as well as management fees arising from the payment of the aforementioned tax at the relevant settlement office, when such expense must be assumed according to regulations.

All of the above does not imply that ABANCA is obliged to grant you the variable mortgage. The personalized offer we finally make you may differ if the conditions of your mortgage change, or if we have additional information about your preferences or financial situation. Also, please note that the conditions of this product are only valid for new arrangements, for individuals with income and assets in euros, US dollars, Swiss francs, pounds sterling, Mexican pesos, Swedish kronor, Norwegian kroner, or Danish kroner declared at the time of the loan study. The income amount for a single holder must be greater than €2,300 per month (or the equivalent in the corresponding currency) and if there are two holders, the minimum amount is €3,500 per month (or the equivalent in the corresponding currency); provided that the contract is made through this website. If you are looking for a subrogation or a novation, come see us at one of our branches and we will study your case together.
