Interest rates for property finance fluctuate, and an increase can make your follow-on financing significantly more expensive. A forward loan enables you to lock in today’s, potentially lower, interest rates for the future.
The topic in brief and concise terms
A forward loan secures today’s interest rates for refinancing up to five years in advance.
Interest rate certainty comes at a premium, which quickly pays off when market interest rates rise.
There is a legal obligation to accept; if it is not accepted, a high compensation payment is due.
Assessing the interest rate risk in refinancing realistically
The current interest rate trend poses a significant financial risk for many property owners. Even a slight rise in the interest rate can have a major impact on the monthly instalment. Experts forecast an interest rate level for 2025 in a range of three to four per cent.
With an outstanding debt of EUR 200,000, an interest rate increase of just one per cent already means EUR 2,000 more in interest costs per year. This additional burden can jeopardise the entire household budget planning. Monitoring the current mortgage interest rate trend is therefore essential.
This uncertainty makes it necessary to address follow-up financing at an early stage, so as not to be caught out by unfavourable market developments.
The way a forward loan works as a hedging instrument
A forward loan is essentially a classic repayment loan that you reserve for the future. Today, you agree a fixed interest rate with a bank for a follow-on financing arrangement that only begins in twelve to 66 months. This period between contract conclusion and disbursement is known as the forward period.
During the forward period, you do not pay commitment interest, which is a clear advantage. You secure today’s terms for tomorrow’s financing. The contract is legally binding, which means that you will also have to take up the loan later.
This approach offers a high degree of planning certainty, as your future monthly instalment is already fixed years in advance. This allows you to calculate and secure your mortgage finance at a favourable rate.
Weighing up costs and benefits: The interest rate premium in detail
For interest-rate certainty over the forward period, the bank charges a so-called forward surcharge. This surcharge typically lies, depending on the provider and market conditions, between 0.01 and 0.03 percentage points per month of lead time.
For a forward period of 24 months and a monthly surcharge of 0.02 per cent, the total interest surcharge comes to 0.48 per cent. If the current construction loan rate is three per cent, the secured forward interest rate is therefore 3.48 per cent. This surcharge is the premium for your insurance against rising interest rates.
Here is an illustrative comparison calculation for an outstanding debt of 150,000 euros:
Scenario A (forward loan): interest rate of 3.5 per cent secured.
Scenario B (waiting): market interest rate rises to 4.5 per cent in two years.
Scenario C (waiting): market interest rate falls to 3.0 per cent in two years.
The decision in favour of a forward loan is therefore a bet on future interest-rate developments, which pays off significantly if interest rates rise.
Determine the optimal time for completion
A forward loan is worthwhile if the expected rise in interest rates is greater than the forward premium payable. Experts recommend closely monitoring the market at the latest 36 months before the fixed-rate period ends. A well-informed decision requires a careful analysis of your personal financial situation and interest rate forecasts.
The following points will help you decide:
Check the amount of your remaining debt and the remaining term.
Compare current forward loan offers from different providers.
Find out about the long-term forecast for interest rate trends.
Calculate the break-even point at which the interest savings exceed the surcharge.
Take into account your personal risk tolerance and your desire for planning certainty.
The longer the forward period, the higher the premium is usually. Weigh up carefully how much the early certainty is worth to you before you consider refinancing.
Risks and legal pitfalls of a forward loan
The biggest risk with a forward loan is the obligation to take it out. You are legally obliged to take out the loan on the agreed terms, even if interest rates have fallen in the meantime. Cancellation is generally not straightforward.
If you do not take out the loan because you no longer need it or have found a better offer, the bank will charge compensation for non-drawdown. This compensation can amount to up to ten per cent of the loan amount and represents a significant financial loss.
Recent rulings by the Federal Court of Justice (BGH) do strengthen consumers' rights in cases of poor advice, but they do not remove the basic obligation to pay. A careful review of your life plans (e.g. moving house, sale) before signing is therefore essential to avoid the need for a early repayment compensation.
Review alternatives to a forward loan
In addition to a forward loan, there are further options for your follow-on financing. A common alternative is prolongation, i.e. extending the loan with your current bank. This is straightforward, but not always the most cost-effective solution.
Another option is a building savings contract, with which you can also secure a fixed loan interest rate for the future. However, this requires a savings phase, which demands additional financial discipline. The interest rates for the building savings loan are often low, but the overall costs can be higher due to the low interest rate during the savings phase.
The third option is a conventional refinancing with a new bank at the end of the fixed-rate period. This offers the chance of the best market terms, but carries the full risk of interest rate changes. Comprehensive advice, such as that offered by nextsure, helps you find the right strategy for your repayment loan.
The decision for or against a forward loan has far-reaching financial consequences. Careful planning and a precise comparison of the options are crucial for your success. Don't wait until the pressure from an expiring fixed-rate period builds.
Act proactively and use the current market conditions to your advantage. An early, well-informed decision protects your assets and secures your home for the future. Start planning your follow-on financing today.

FAQ
What is a forward loan?
A forward loan is a form of follow-on financing. You enter into a loan agreement today with a fixed interest rate, but it is only paid out in the future (e.g. in one to five years) in order to replace your existing property finance.
What are the advantages of a forward loan?
The main advantage is planning certainty. You protect yourself against future interest rate rises and already know your monthly instalment for the follow-on financing years in advance. In addition, no commitment interest accrues during the lead time.
What are the disadvantages and risks?
The biggest disadvantage is the obligation to accept it. If interest rates fall contrary to your expectations, you must still accept the loan on the more expensive, agreed terms. In addition, banks charge an interest premium for providing it.
What is the difference between a genuine and a non-genuine forward loan?
In a true forward loan, the agreed fixed-interest period (e.g. ten years) only begins when the funds are disbursed. In a notional forward loan, the fixed-interest period begins as soon as the contract is signed, which shortens the effective term after disbursement.
What is a non-acceptance compensation?
If you do not draw down the forward loan in breach of contract, the bank incurs an interest loss. It will charge you for this loss in the form of compensation for non-acceptance, which can be very high.
What alternatives are there to a forward loan?
Alternatives are extending the loan with the existing bank (prolongation), taking out a new loan with another bank when the fixed-rate period ends (refinancing), or securing it through a home savings contract.
