Interest rate

The interest rate is the percentage that a borrower pays annually on the borrowed capital as a fee for its use, or that an investor receives for capital provided. In the real estate sector, we encounter it primarily as the nominal interest rate (the interest rate specified in the loan agreement) and as the annual percentage rate (APR) (which includes all financing costs). The interest rate is thus one of the key factors that determine the total cost of real estate financing.

Debit Interest Rate, Nominal Interest Rate, and Effective Annual Interest Rate

The debit interest rate indicates how much interest is charged annually on the outstanding balance-without any additional costs. The effective annual interest rate (also known as the APR), on the other hand, includes all financing costs: processing fees, account maintenance fees, and any commissions. Since the Residential Mortgage Credit Directive (2016), banks have been required to disclose the effective annual interest rate transparently and present it on the same page as the nominal interest rate.

When comparing different loan offers, only the effective interest rate is meaningful. Two loans with identical nominal interest rates can have significantly different effective interest rates if one is subject to account maintenance fees, appraisal fees, or a discount. Caution: When comparing subsidized offers (KfW) with market offers, note that KfW terms often include additional repayment subsidies that are not reflected in the effective interest rate-the total effective benefit must therefore be calculated separately.

Variable and Fixed Interest Rates

Mortgage loans are offered either with a fixed interest rate (fixed for an agreed term) or a variable interest rate (adjusted to a reference rate, usually EURIBOR). The fixed interest rate protects against market fluctuations and allows for predictable monthly payments; it typically comes with a premium compared to the variable option.

Variable interest rates are suitable for borrowers who want to pay off their loan quickly or are speculating on falling interest rates-but they bear the full market risk. During periods of sharply rising interest rates, such as in 2022/2023, this risk became a very real reality for holders of variable-rate loans: Those who financed at a 1% variable rate in 2021 suddenly paid over 5% in 2023-a tripling of the monthly interest burden. Variable-rate loans are therefore only suitable for very specific situations and require sufficient liquidity buffers.

Factors Influencing the Individual Interest Rate

The bank does not set the interest rate identically for all customers. The key factors are: the borrower’s creditworthiness (Schufa score, income level and stability), the loan-to-value ratio (ratio of loan amount to property value), the fixed-rate period, and the chosen repayment rate. The higher the equity and the better the creditworthiness, the lower the individual interest rate.

Even a difference of just 0.2 percentage points adds up to several thousand euros over the term of the loan when dealing with large loan amounts. Specifically: For a €350,000 loan with a 15-year fixed-rate period, a 0.2 percentage point lower interest rate translates to total savings of approximately €10,500. This makes it worthwhile to invest time in carefully comparing banks-since the difference between the best and worst offers can easily be threefold.

Interest Rate and Repayment Schedule: How They Interact

The interest rate affects not only the monthly payment but also the time it takes to become completely debt-free. With a high interest rate, a larger portion of the monthly payment goes toward interest and less toward principal repayment-which significantly extends the total term even with the same repayment rate. A loan of 300,000 euros at 1% interest and 2% principal repayment is paid off after about 35 years; at 4% interest and the same principal repayment rate, it takes over 50 years. That is why it is particularly important during periods of high interest rates to choose a sufficiently high principal repayment rate.

Practical Tip for Homeowners in Nuremberg and Franconia

In the Nuremberg metropolitan area, purchase prices for single-family homes and condominiums often exceed 400,000 euros-even small differences in the interest rate thus have a noticeable impact on the total cost. We recommend not only obtaining an offer from your primary bank but also comparing at least three to five financing offers, including those from regional cooperative banks (VR Banks in Nuremberg, Raiffeisen Banks in Franconia), Sparkasse Nuremberg, nationwide direct banks, and financing brokers.

We would be happy to put you in touch with independent financing brokers in Nuremberg who can filter out the most favorable offer from a pool of over 400 banks and also incorporate KfW subsidy programs.

Frequently Asked Questions

What is the difference between the nominal interest rate and the effective interest rate?

The nominal interest rate is the pure interest rate on the loan amount, while the effective interest rate includes all other costs (fees, discount, etc.). For a meaningful comparison of loan offers, the effective interest rate must always be used-an offer with a low nominal interest rate but high processing fees can be more expensive overall than an offer with a slightly higher nominal interest rate and no extra costs.

How does a higher repayment rate affect the interest rate?

A higher initial repayment rate shortens the term of the loan and thus the total interest burden. It has no direct influence on the contractually agreed interest rate itself. However, the bank takes the overall risk profile into account when determining the interest rate: A high repayment rate is a sign of creditworthiness and willingness to repay, which can indirectly have a positive effect on the terms.

Can I lower my interest rate later on?

A reduction is not possible unilaterally within the agreed fixed-rate period. After the fixed-rate period expires or in the event of a special right of termination pursuant to Section 489 of the German Civil Code (BGB) (after ten years), the loan can be renegotiated or refinanced under more favorable terms. Switching banks for renewal is easily possible and often worthwhile-the bureaucratic hurdles (new land charge, assignment) are manageable.

What does “negative interest rate” mean, and is this possible for real estate loans?

Negative interest rates mean that borrowers are paid for borrowing money. During the low-interest-rate period up to 2022, some banks charged negative interest rates (custody fees) on deposits (savings balances). For real estate loans, however, negative nominal rates were extremely rare-the vast majority of mortgages still had a positive borrowing rate even in a zero-percent environment, as the bank must factor in its margin (risk premium, administrative costs).
