Variable interest rate

Variable-Rate Mortgage - With a variable-rate mortgage, the interest rate on a home loan is not fixed for a set period but is regularly adjusted to a reference rate (in the Eurozone, the EURIBOR). As a result, the monthly payment changes with market conditions - when interest rates fall, the loan becomes cheaper; when they rise, it becomes more expensive. Variable-rate loans offer maximum flexibility, as they can be terminated at any time with three months’ notice and without a prepayment penalty.

How It Works and Interest Rate Adjustments

The interest rate on a variable-rate loan consists of the reference rate (usually the 3-month or 6-month EURIBOR) and a bank margin (typically 0.8-2.0 percentage points). Adjustments are generally made every 3 or 6 months. If the EURIBOR rises by 0.5 percentage points, the loan interest rate also rises by 0.5 percentage points-and with it, the monthly payment. There is no fixed-rate period and no prepayment penalty upon termination. The notice period is 3 months pursuant to Section 489(2) of the German Civil Code (BGB).

It is important to know the current EURIBOR rate and to calculate the impact of interest rate changes on your own monthly payment before deciding on a variable-rate loan. Anyone taking out a variable-rate loan should always perform a stress test: “What happens if the interest rate rises by 2 percentage points?” For a loan of 400,000 euros, this means an additional burden of approximately 667 euros per month-an amount that can be a matter of survival for many households.

Applications and Risks

Variable-rate loans are suitable for: bridge financing (when proceeds from a sale are expected and the loan is to be repaid in the short term), investors anticipating falling interest rates (who are betting on lower rates and then wish to switch to a fixed-rate term), and interim financing until the payout of a life insurance policy or a home savings contract. The main risk is a rise in interest rates: For a loan of 300,000 euros, every percentage point increase in interest rates means an additional monthly payment of approximately 250 euros. Without protection (e.g., an interest rate cap), a sharp rise in interest rates can jeopardize affordability.

For professional investors with multiple properties, a variable interest rate can also be used strategically to create a liquidity buffer: During periods of low interest rates, as much as possible is paid off; when interest rates rise, the loan may be repaid early using other liquid funds. This flexibility comes at a price-namely, the risk awareness and financial discipline required for such a strategy.

Practical Tip for Property Owners in Nuremberg

We recommend that real estate buyers in the Nuremberg metropolitan area use variable-rate loans only as a tactical tool-not as the primary financing for owner-occupied properties. Typical scenario: You have sold a property in Nuremberg-Erlenstegen, the proceeds are due in 6 months, and you want to buy a new apartment now. A variable-rate loan cost-effectively bridges this gap and is repaid immediately upon receipt of the sale proceeds.

For long-term financing, we recommend a fixed-rate term of at least 10 years-the planning security is generally worth the interest premium. In the current market phase, with moderate interest rates following the 2022/2023 peak cycle, it is worth seriously considering the terms for long-term fixed-rate periods (15-20 years). We would be happy to put you in touch with independent financial advisors in the metropolitan area.

Frequently Asked Questions

What is the difference between a variable-rate loan and a fixed-rate loan?

With a fixed-rate mortgage, the interest rate remains constant for 5, 10, 15, or more years-the payment is predictable, but early termination incurs a prepayment penalty. With a variable-rate mortgage, the interest rate adjusts regularly to market conditions-the payment fluctuates, but termination is possible at any time with 3 months’ notice. In practice, variable-rate loans are often cheaper initially than fixed-rate loans because the bank does not assume the risk of interest rate fluctuations.

Can I switch from variable to fixed?

Yes, most banks offer the option to convert a variable-rate loan into a fixed-rate loan at any time. You will then receive the current market interest rate for the desired fixed-rate period. This switch makes sense when interest rates are at an attractive level and you want to gain planning security. Some banks include this option in the loan agreement from the start-be sure to ask about it before signing the loan agreement.

What is an interest rate cap?

An interest rate cap is a contractual upper limit on the interest rate for a variable-rate loan. If the market interest rate rises above the cap, you still only pay the capped interest rate-the bank (or the cap provider) covers the difference. For this protection, you pay a one-time premium (approx. 0.5-2% of the loan amount). A cap combines the flexibility of a variable-rate loan with a limit on upward interest rate risk and is a particularly useful hedging tool during periods of interest rate uncertainty.

How is the EURIBOR performing currently, and what does this mean for variable-rate loans?

The EURIBOR (Euro Interbank Offered Rate) eased noticeably starting in mid-2024 following the 2022/2023 peak cycle, as the European Central Bank began gradually lowering key interest rates. The 3-month EURIBOR stood in the range of 2.5% to 3.0% at the beginning of 2026. Variable-rate loans benefit directly from this: Borrowers who took out variable-rate loans during the high-interest-rate phase feel the relief after every interest rate adjustment. At the same time, it is important to note that the EURIBOR can rise as well as fall-a robust stress test remains essential. Anyone with a variable-rate loan in the Nuremberg metropolitan area should check with every interest rate adjustment whether switching to a longer fixed-rate term makes sense given the current interest rate level.
