Mortgage Overpayment: Reduce the Term or the Payment?

Do you have a mortgage and plan to make a sizeable overpayment? The key question is: are you better off reducing your monthly payment or the remaining term of the loan?

‍
Making the right decision can help you save on interest, gain liquidity or simply protect your capital for the future. This article draws on wealth management and private banking experience to help you choose with confidence and clarity.

‍

Reducing the term vs reducing the payment: how does each option work?

• Reducing the term: You pay off the loan in less time while keeping your current monthly payment. The big benefit is that you cut the total interest paid dramatically, since the years over which the bank charges you for the borrowed money are shortened (especially under the French amortization system used in Spanish mortgages)
• Reducing the payment: You keep the original term but lower the amount you pay each month. This improves your liquidity and gives you more room to spend or invest, although the interest savings are smaller.

‍

A practical example: visualize your savings

‍

Suppose you have a €150,000 mortgage at a 2% fixed rate over a total term of 30 years.
After 15 years, you decide to pay off €25,000 in one go. What is the impact if you choose to reduce the monthly payment or the remaining term?

‍

Advantages and risks of each alternative: decide according to your wealth profile

‍

‍

• Reducing the term is usually more profitable, especially early in the loan and if you can comfortably keep paying the same monthly amount.
• Reducing the payment is valuable if you are looking for better liquidity, a buffer for the unexpected, or to diversify your investments across funds, portfolios or real estate projects.

Practical tips for investors

1. Assess your current and future liquidity: Would you rather cut interest costs or gain month-to-month breathing room?
2. Analyze your risk profile and investment strategy: If you can invest the "freed-up" money with better returns or more security, reducing the payment can be a smart move.
3. Check your bank's conditions: Tax treatment and early repayment fees in Spain can influence the decision.
4. Get ahead of possible rate rises: If your loan is variable-rate and you fear interest rates may rise in the future, reducing the term protects you more.

Conclusion

The most suitable option depends on your wealth strategy, risk profile and financial goals:

• Do you want to save on interest and finish paying earlier? Reduce the term.
• Do you prefer liquidity and flexibility to invest in other assets? Reduce the payment.
