Repayment determines how long you will be paying off your mortgage and how much interest will accumulate in the end. Just one percentage point more in initial repayment shortens the term by many years and saves a five-figure amount in interest. We explain how the repayment rate works, when 2 or 3 percent are worthwhile, and what role extra repayments play in the speed of your repayment.
What does repayment mean – and what is the repayment rate?
Repayment is the part of your monthly instalment with which you pay back the actual loan debt. The second component is the interest that the bank charges for providing the money. With the type of mortgage financing customary in Germany – the annuity loan – the monthly instalment remains constant throughout the fixed-interest period and consists of interest and repayment.
The clever part is this: With each instalment, the outstanding debt decreases, which reduces the interest component; because the instalment remains the same, the repayment component automatically increases. Repayment therefore accelerates by itself – slowly at first, then increasingly faster towards the end.
The repayment rate (also initial repayment or initial repayment rate) indicates what percentage of the loan amount you repay in the first year. With an initial repayment rate of 2 percent and a loan of 300,000 euros, you repay 6,000 euros in the first year. The monthly instalment can be roughly calculated simply: nominal interest rate plus repayment rate, divided by twelve, applied to the loan amount.
How the repayment rate determines the term and total costs
The repayment rate is the strongest lever for determining the speed of repayment. A calculation example makes this clear. Suppose you take out 300,000 euros at a nominal interest rate of 3.8 percent – a realistic level for a ten-year fixed-interest period in 2026. Depending on the initial repayment rate, this results in very different terms (without extra repayments and under the simplifying assumption of unchanged conditions):
- 1 percent repayment: around 1,200 euros per month, debt-free only after just over 40 years
- 2 percent repayment: around 1,450 euros per month, debt-free after around 29 years
- 3 percent repayment: around 1,700 euros per month, debt-free after just under 22 years
- 4 percent repayment: around 1,950 euros per month, debt-free after around 18 years
You can see: In this example, the difference between 1 and 2 percent repayment is an entire decade in term. Even The effect is even clearer when it comes to interest costs. Over the entire term, you pay around 195,000 euros in interest in the example with 2 percent initial repayment, and only about 147,000 euros with 3 percent. That is a difference of almost 50,000 euros – with a monthly payment that is only around 250 euros higher.
2 Percent or 3 Percent? The Right Initial Repayment in 2026
For many years, 1 percent was considered the usual repayment rate – reasonable during the period of low interest rates because a low interest rate barely allowed the remaining debt to grow. Today, the situation is different: With mortgage rates of around 3.6 to 4.3 percent, the interest component consumes a large part of a low monthly payment. With 1 percent repayment, you would be paying for decades.
The rule of thumb today is therefore: at least 2 percent initial repayment, and in the current interest-rate environment preferably 3 percent, provided your budget allows it. Consumer protection organizations also generally recommend at least 2 percent and advise a higher rate at current interest levels.
However, the appropriate amount depends on your personal situation:
- Your age: Anyone who wants to be debt-free before retirement must repay faster when entering the market late.
- Your income: The payment must remain affordable over the long term – even if one salary is lost. Build in a buffer.
- Your financial planning security: If you expect salary increases or an inheritance, use the flexibility later through additional repayments.
The key is balance: A high repayment rate makes you debt-free faster, but it must not overburden you financially. Before deciding on a payment, you should know which properties are actually within your budget – on TraumImmo, you can compare offers from various portals in one place.
Additional Repayment: Reach Your Goal Faster With Flexibility
In addition to regular repayment, there is a second lever for controlling the pace: additional repayment. This allows you to repay an extra amount outside the regular schedule, for example from your Christmas bonus, a bonus or an inheritance. Each additional repayment immediately reduces the remaining debt and shortens the term.
With most mortgage loans, an annual additional repayment of up to 5 percent of the original loan amount is now possible free of charge. Higher additional payments of up to 10 percent can often be agreed upon in exchange for a small interest-rate surcharge of around 0.25 percentage points.
Bear two points in mind:
- The additional repayment is not a legally guaranteed right, but a contractually agreed Special repayment right. Whether it is possible, how often, and in what amount is specified in the loan agreement. Pay attention to this when concluding the agreement.
- If you repay more than agreed, the bank may demand early repayment compensation during the fixed-interest period for lost interest. For real estate loans with a fixed borrowing rate, early repayment during the fixed-interest period is only freely possible if there is a legitimate interest (§ 500 BGB).
An agreed special repayment right combines both worlds: You keep the fixed rate moderate while still picking up the pace as soon as you have money left over.
Remaining debt and interest-rate risk: Why speed pays off
The fixed-interest period usually lasts ten years, but by then the loan will generally not yet have been fully repaid. What remains is the remaining debt, which you continue to repay through follow-up financing – at the interest rates applicable then. This is precisely where a higher repayment rate pays off a second time.
Germany’s Federal Financial Supervisory Authority BaFin puts it simply: The lower your remaining debt, the more favorable the interest rates for follow-up financing – because the ratio of remaining debt to the property’s value also determines your terms (BaFin).
Those who repay slowly enter follow-up financing with a high remaining debt and face considerable interest-rate change risk: If interest rates rise by then, the subsequent payment will become noticeably more expensive. With an initial repayment rate of just 1 percent, it can rise significantly, whereas with a 3 percent repayment rate it remains almost unchanged – because the remaining debt has already fallen sharply by then.
Good to know: Regardless of the agreed term, you may cancel any loan with a fixed borrowing rate free of charge after ten years with six months’ notice (§ 489 BGB). The notice period begins when the loan has been paid out in full. You are therefore never tied to an interest rate for longer than ten years – an important reason not to put artificial pressure on yourself because of the repayment pace.
Advantages and disadvantages of a high repayment rate
A high repayment rate is not automatically the best choice. You should weigh these points:
- Advantage – shorter term: You will be debt-free years earlier and often in good time before the Retirement.
- Advantage – lower interest costs: Faster repayment significantly reduces the total interest paid.
- Advantage – lower interest-rate risk: The lower remaining debt makes you less dependent on interest rates for the follow-up financing.
- Disadvantage – higher monthly payment: Each additional percentage point of repayment increases the fixed burden and restricts your financial flexibility.
- Disadvantage – less flexibility: Anyone committing to a high payment has less leeway in the event of a loss of income. A right to make extra repayments is often the more flexible alternative.
- Disadvantage – alternative return: Depending on the situation, it may make more sense to invest available funds instead of using them for repayment – repayment does, however, provide a secure, tax-free return equal to the borrowing rate.
FAQ on Repayment
What is a good repayment rate in 2026?
In the current interest-rate environment, an initial repayment rate of 2 to 3 percent is considered a sensible guideline; with an affordable budget, it is better to be at the upper end. You should stay below 2 percent only in exceptional cases, because otherwise the term and remaining debt will be very high.
Can I change the repayment rate later?
Many banks offer a repayment-rate change: You can adjust the repayment rate during the fixed-interest period – usually two or three times – within certain limits. Whether and how often this is possible is stated in the loan agreement. Look out for this option when signing the agreement; it generally costs nothing extra and provides flexibility.
How much extra repayment is sensible?
The basic principle is: Every euro you put toward an extra repayment saves you interest equal to your borrowing rate. In the current interest-rate environment, make use of the fee-free right to make extra repayments – often up to 5 percent of the loan amount per year – to the extent your reserves allow. However, you should always retain an emergency reserve for unforeseen circumstances.
Is full repayment sensible?
With a fully amortizing loan, the property is fully paid off at the end of the fixed-interest period. The advantage: complete planning certainty, no interest-rate change risk, and often a small interest-rate discount. The disadvantage: The payment is high and fixed for the entire term. This is particularly sensible with a stable income that can reliably cover the payment in the long term.
What happens to my loan after ten years?
Ten years after full disbursement, you have a statutory right to terminate early: You can terminate the loan free of charge with six months' notice cancel – in full or in part (Section 489 of the German Civil Code (BGB)). This is particularly worthwhile if interest rates have fallen. No early repayment penalty is incurred in this case.
Conclusion: Speed with a sense of proportion
Repayment is the key factor determining how quickly your property truly belongs to you. A higher repayment rate shortens the term by years, saves a five-figure sum in interest and reduces the remaining debt – and thus the interest-rate risk when refinancing. In the interest-rate environment of 2026, an initial repayment rate of 2 to 3 percent is a good benchmark, provided the instalment remains affordable over the long term. Combining a moderate fixed repayment rate with the right to make penalty-free additional repayments is a good way to balance speed and security.
