Annuity loan

Annuity Loan - The annuity loan is the most common type of loan used for real estate financing in Germany. It is characterized by a fixed monthly payment (annuity) consisting of an interest portion and a principal portion, with the principal portion increasing steadily over the term of the loan.

What exactly does an annuity loan mean?

With an annuity loan, the borrower pays a constant monthly installment to the financing bank over the entire fixed-rate period. This installment-the annuity-consists of two components: the interest portion, which is calculated on the remaining principal balance, and the principal repayment portion, which reduces the loan balance.

The central principle of the annuity loan is based on a systematic shift within the constant payment: Since the remaining debt decreases with each principal payment, the interest portion of the next payment also decreases. However, because the total payment remains constant, the principal portion increases by the same amount. Thus, at the beginning of the term, the largest portion of the payment goes toward interest, while toward the end of the term, the principal repayment clearly predominates.

The fixed-rate period-that is, the period during which the agreed-upon interest rate is fixed-is typically 10, 15, or 20 years in practice. Once the fixed-rate period expires, follow-up financing must be arranged for the remaining balance, provided the loan has not been fully repaid. The interest rate risk associated with follow-up financing is the main disadvantage compared to full repayment.

The initial principal repayment rate is set at the time the contract is signed and typically amounts to between 1% and 4% of the loan amount per year. The higher the initial principal repayment rate chosen, the faster the loan is repaid-though this also results in a higher monthly payment. Experts currently recommend an initial principal repayment rate of at least 2% to keep the total loan term within a reasonable range.

Calculation and Functioning of the Annuity

The annual annuity is calculated using the formula:

Annuity = Loan Amount × (Interest Rate + Initial Principal Payment)

An example: For a loan of 300,000 euros with a borrowing rate of 3.5% and an initial repayment of 2%, the annual annuity is 16,500 euros-which corresponds to a monthly payment of 1,375 euros.

In the first month, 875 euros of this amount goes toward interest and 500 euros toward principal repayment. By the final month of the fixed-rate period after 15 years, the ratio has already shifted significantly: The principal portion far exceeds the interest portion, as the remaining debt has fallen to around 209,000 euros due to ongoing principal payments.

Many banks also offer the option of a special repayment-that is, an additional payment outside of the regular installment. Typically, this amounts to 5% of the original loan amount per year. Extra payments shorten the total term and noticeably reduce interest costs.

Practical Tip for Homeowners in Nuremberg and Franconia

Real estate prices in the Nuremberg metropolitan area have stabilized at a high level in recent years. For a typical existing apartment in neighborhoods such as Maxfeld, Gleißhammer, or Schweinau, the loan amount often ranges between 250,000 and 400,000 euros-amounts where choosing the right repayment amount and fixed-rate period can make a difference of tens of thousands of euros in interest costs.

Our network of experts recommends obtaining at least three offers from regional and national banks when choosing an annuity loan, and comparing not only the nominal interest rate but also the effective interest rate, the options for special repayments, and the terms for follow-up financing. We are happy to put you in touch with independent financial advisors in the Nuremberg region.

Frequently Asked Questions

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

The nominal interest rate (also known as the base rate) refers to the pure interest rate that the bank charges for the loan. The effective interest rate, on the other hand, also takes into account additional costs such as processing fees, the method of calculating principal repayment, and the disbursement rate. It is therefore always higher than the nominal interest rate and is better suited for comparing different loan offers, as it reflects the actual annual cost.

What fixed-rate term is currently recommended?

The optimal fixed-rate term depends on current interest rates and your personal financial plans. During periods of low interest rates, a fixed-rate term of 15 or 20 years is recommended to lock in the favorable rate for the long term. When interest rates are higher, a shorter term of 10 years may make sense if falling rates are expected in the medium term. As a general rule: After ten years, any loan can be terminated with six months’ notice (Section 489 of the German Civil Code).

Can the monthly payment be changed during the term?

With a traditional amortization loan, the payment remains constant throughout the entire fixed-rate period. However, some banks offer flexible options where the repayment rate can be adjusted once or several times during the term-for example, from 2% to 3% or vice versa. This flexibility is particularly valuable if the borrower’s financial situation changes, such as due to parental leave or a job change.

What happens after the fixed-rate period ends for an annuity loan?

After the fixed-rate period ends-often after 10, 15, or 20 years-the loan is usually not yet fully repaid. The remaining balance must be refinanced. To do this, either the current bank can offer an extension, or the borrower can switch to another lender (refinancing). The interest rates for the follow-up financing depend on the prevailing interest rates at that time-this is where the main risk of an annuity loan lies. To limit this risk, borrowers can take out a so-called forward loan up to twelve months before the fixed-rate period expires, which locks in today’s interest rate for a future disbursement date. In exchange for a premium on the current interest rate-typically 0.01 to 0.03 percentage points per month of lead time-the borrower secures planning certainty. In the Nuremberg metropolitan area, where many buyers financed real estate during the low-interest-rate years from 2012 to 2021, numerous refinancing deals at significantly higher interest rates are due in the coming years. We recommend starting to compare offers early-at least 18 months before the fixed-rate period expires.
