Initial Repayment Rate in German Mortgages: 2%, 3% or 4%?

When you apply for a mortgage in Germany, the bank will not only ask how much you want to borrow and what fixed-rate period you prefer. It will also ask for something many buyers initially find confusing:

What anfängliche Tilgung (initial repayment rate) do you want: 2%, 3% or 4%?

It sounds like a small technical detail. In reality, it drives four big outcomes: your monthly payment, how fast the loan balance falls, how much interest you pay, and the remaining balance when your fixed-rate period ends.

In plain English: the initial repayment rate is the annualised principal-repayment rate at the start of the loan. Together with the nominal borrowing rate, it determines the initial payment.

If you borrow €300,000 and choose a 2% initial repayment rate, the starting principal repayment is €6,000 a year, or €500 in the first monthly payment. Because the interest portion then falls each month, this article’s model actually repays €6,111.23 of principal over the first 12 payments. The €6,000 is the annualised starting amount, not the exact first-year total.

Quick answer: 2%, 3% and 4% create very different loans

Assume a €300,000 mortgage, a Sollzins (nominal borrowing rate) of 4.0% and a standard Annuitätendarlehen (annuity loan). The interest rate is assumed to stay unchanged until the loan is fully repaid. This is only an illustration.

To reproduce the comparison in German Immo Flow, first set Repayment Type to Annuity Loan. Enter purchase costs and available equity so that the displayed Loan Amount is €300,000. Save the base scenario, keep every other input unchanged, and vary only Initial Repayment. The calculator assumes the entered interest rate continues over the modelled payoff period; it does not forecast the rate after a fixed-rate period ends. Equal-principal repayment produces different results.

The key takeaway: moving from 2% to 3% adds €250 to the monthly payment, but cuts the repayment period by roughly six years and reduces total interest by about €49,600.

This is why Verbraucherzentrale (German Consumer Advice Centre) stresses that a higher initial repayment rate pays down the loan faster.¹ Stiftung Warentest (German consumer testing organisation) also notes that even a one-percentage-point difference in the repayment rate can shorten the loan term by many years and save tens of thousands of euros in interest.²

1. What exactly is the initial repayment rate?

The initial repayment rate describes:

the annualised principal-repayment rate at the start of the loan.

Example:

• Loan amount: €300,000
• Nominal borrowing rate: 4.0% p.a.
• Initial repayment rate: 2.0% p.a.

The initial annual payment is:

Loan amount × (nominal borrowing rate + initial repayment rate)
= 300,000 × (4.0% + 2.0%)
= €18,000 per year
= €1,500 per month

In a German mortgage offer, you may see something like this:

Sollzins (nominal borrowing rate): 4.00% p.a.
Anfängliche Tilgung (initial repayment rate): 2.00% p.a.
Monthly payment: €1,500

The 2% is neither the interest rate nor the total cost of the loan. It sets the starting principal portion. In the first month, €1,000 of the €1,500 payment is interest and €500 is principal. The interest portion then falls each month, so the first 12 payments repay €6,111.23 of principal in total.

2. Why is it called “initial” repayment?

Because with a standard German annuity mortgage, your monthly payment usually stays the same during the fixed-rate period, but the split inside that payment changes over time.

Your payment has two parts:

Monthly payment = interest + principal repayment

At the beginning, the outstanding loan balance is high, so the interest portion is high and the principal portion is lower. As you repay principal month by month, the outstanding balance falls. The next interest charge becomes smaller. Since the monthly payment stays the same, more of it goes towards principal.

The German Consumer Advice Centre explains the same mechanism for German mortgage loans: the monthly annuity consists of interest and principal repayment; as the original loan amount is gradually reduced, the interest portion falls and the principal portion rises.¹

The initial repayment rate therefore describes only the starting point. After that, the amount of principal repaid each month rises automatically.

3. What does the initial repayment rate change?

3.1 Monthly payment: higher repayment means a higher payment

With the same interest rate and loan amount, a higher initial repayment rate means a higher monthly payment.

For a €300,000 loan at 4.0% interest:

• 2% repayment: about €1,500 per month
• 3% repayment: about €1,750 per month
• 4% repayment: about €2,000 per month

That means 4% is not automatically “better”. If it leaves you with no emergency buffer, it can create its own risk.

3.2 Repayment time: higher repayment means debt-free sooner

Using the same €300,000 example at 4.0% interest:

• 2% repayment: paid off after about 27.6 years
• 3% repayment: paid off after about 21.3 years
• 4% repayment: paid off after about 17.4 years

The German Consumer Advice Centre recommends that borrowers plan the mortgage term so that the loan is repaid by retirement where possible. It also gives a simple warning: at around 3% interest, a 1% initial repayment rate can stretch the loan to about 46 years, while a 3% rate can repay it in a little over 23 years.³

3.3 Total interest: higher repayment means less interest paid to the bank

The faster you reduce the balance, the smaller the amount on which interest is charged. In our €300,000 example:

• 2% repayment: total interest of about €195,199
• 3% repayment: total interest of about €145,573
• 4% repayment: total interest of about €116,582

The difference quickly reaches tens of thousands of euros.

3.4 Remaining balance after the fixed-rate period: lower repayment can increase follow-on financing risk

Most German mortgages have a Sollzinsbindung (fixed-rate period), such as 10, 15 or 20 years. If the loan is not fully repaid by the end of that period, you need an Anschlussfinanzierung (follow-on financing).

If market rates are higher at that point and your remaining balance is still large, the new payment can become painful. The German Consumer Advice Centre explicitly warns that a balance remaining after the fixed-rate period must be financed at the then-current market rate; if rates have risen, the additional burden can strain the household budget.¹

In our €300,000 example at 4.0% interest:

• 1% repayment: about €263,187 left after 10 years
• 2% repayment: about €226,375 left after 10 years
• 3% repayment: about €189,563 left after 10 years
• 4% repayment: about €152,750 left after 10 years

That is the link between the initial repayment rate and follow-on financing risk: you are not only deciding what you can afford today; you are deciding how large a balance you may carry into the next rate cycle.

4. Why the initial repayment rate matters more in the 2026 rate environment

At this article’s 2 August 2026 update, published 10-year mortgage examples varied with loan-to-value ratio and borrower profile. Interhyp listed effective annual rates of 3.80%, 3.87% and 4.14% across three loan-to-value bands, based on offers from 20–26 July 2026.⁴ Dr. Klein’s representative €350,000 example dated 2 August showed a 3.66% fixed nominal borrowing rate and 3.75% effective interest for a 10-year fixed period.⁵ Nominal borrowing and effective rates are not interchangeable, and provider assumptions differ. The calculator’s 4.0% nominal borrowing rate in this article is a deliberately rounded planning assumption, not a market average or personalised quote.

This makes the choice of initial repayment rate more consequential than it was during the low-rate years.

When mortgage rates were close to 1%, many buyers could use a low initial repayment rate and still keep payments manageable. At around 4%, interest already consumes a large share of the monthly payment. If the initial repayment rate is also low, two things can happen:

1. the payment may look manageable, but the loan balance falls slowly;
2. a large remaining balance is left when the fixed-rate period ends.

So the better question is not only “what is the interest rate?” It is:

At this interest rate, is my initial repayment rate high enough to reduce the remaining balance within a reasonable time?

5. Should you choose 2%, 3% or 4%?

There is no universal answer. A practical decision process looks like this.

Step 1: Start with a payment you can live with for years

Do not begin with “what repayment rate sounds good?” Begin with:

Could I still make this payment if my income changes, I have a child, the property needs repairs, or energy costs rise?

A mortgage payment should not be merely possible. It should be sustainable. The budget also needs a repair reserve, insurance, annual property tax, energy and normal living costs. Apartment owners should additionally include the Hausgeld (condominium service charge); owners of houses should budget separately for running and maintenance costs.

Step 2: Decide whether the loan should be gone by retirement

If you buy at 35, a 25- to 30-year repayment path may still be reasonable. If you buy at 50, the same term may be too long. The German Consumer Advice Centre recommends choosing the repayment plan so the mortgage does not run beyond retirement where possible.³

Step 3: Look at the remaining balance after the fixed-rate period

Many buyers focus on the monthly payment and forget the balance after 10 or 15 years. Compare at least three numbers:

• What is the remaining balance after the fixed-rate period?
• Could I afford the payment if the follow-on financing rate were 5% or 6%?
• Would a longer fixed-rate period or a higher repayment rate reduce the risk?

Step 4: Keep flexibility instead of maxing out the monthly payment

A higher repayment rate saves interest, but a very high fixed payment reduces flexibility. A more balanced setup may be:

• choose a stable monthly payment you can afford;
• negotiate a contractual Sondertilgung (unscheduled repayment) option;
• use bonuses or extra savings for additional principal payments;
• check whether the contract allows a Tilgungssatzwechsel (repayment-rate change).

The German consumer testing organisation recommends comparing mortgage offers using identical assumptions, such as the same loan amount, monthly payment and fixed-rate period. Otherwise, the offers are not truly comparable.⁶

6. Owner-occupiers and investors should think about repayment differently

Owner-occupiers: focus on security and being debt-free in time

If you buy a home to live in, repayment planning is mostly about safety:

• the payment should not overstretch your household budget;
• the remaining balance after the fixed-rate period should be manageable;
• the loan should ideally be repaid before retirement;
• total interest should not get out of control.

For many buyers, 2% is a starting point rather than a final answer. If the budget allows it, 3% or more can reduce future risk substantially.

Investors: repayment lowers cash flow, but also lowers leverage risk

For rental investors, there is one important distinction:

For a rental property, principal repayments are not deductible against rental income, although they are real cash outflows.

Interest on a loan may be deductible when it is economically connected to the rental income. Principal repayment instead reduces the loan balance and free cash flow; it does not reduce taxable rental income.

So investors need to look at both sides:

• higher repayment: tighter monthly cash flow, but a faster reduction in the loan balance and lower follow-on financing risk;
• lower repayment: more cash available today, but a higher remaining balance and more leverage risk.

7. Common mistakes

Mistake 1: Looking only at the interest rate

Two loans can both have a 4% interest rate. If one has a 1% repayment rate and the other has a 3% repayment rate, they are completely different repayment plans.

Mistake 2: Thinking a low monthly payment means the loan is cheap

A low payment can simply mean that you are repaying very little principal. It may feel comfortable today but increase long-term interest and follow-on financing risk.

Mistake 3: Ignoring the remaining balance after 10 years

The balance left after the fixed-rate period determines how exposed you are to future rate changes.

Mistake 4: Setting the repayment rate too high

A result that works on paper can still leave too little room for repairs, income changes or changing family costs.

FAQ

Is a higher initial repayment rate always better?

No. It can reduce debt faster and save interest, but it also increases the monthly payment. If it leaves you without a cash buffer, it may not be the right choice.

Is 2% initial repayment enough?

It can be a reasonable starting point, but it is not automatically enough. It depends on the loan amount, interest rate, your age, income stability, fixed-rate period and target payoff time. In a rate environment around 4%, many buyers should compare 2%, 3% and 4% side by side.

Why might a low interest rate require a higher repayment rate?

Because the monthly payment consists of interest plus principal. If both the interest rate and the repayment rate are low, the loan balance falls very slowly. The German Consumer Advice Centre gives an example where a 1% initial repayment rate at roughly 3% interest can stretch the loan to about 46 years.³

What is the difference between principal repayment and an unscheduled repayment?

Principal repayment is the regular reduction of the loan balance built into your monthly payment. An unscheduled repayment is an additional voluntary payment permitted by the contract, often up to an annual limit such as 5% of the original loan amount. It gives you flexibility without locking yourself into a higher payment every month.

Am I locked in forever if I choose a fixed-rate period longer than 10 years?

Under §489 of the Bürgerliches Gesetzbuch (BGB) (German Civil Code), borrowers may, under specific conditions, terminate a fixed-rate loan 10 years after full disbursement with six months’ notice.⁷ If the parties later agree new terms for the repayment period or borrowing rate, the date of that agreement replaces full disbursement as the start of the 10-year period. The exact timing therefore depends on the contract, disbursement and any later agreement, so check the details before relying on it.

---

Conclusion: repayment rate is the mortgage number buyers often underestimate

The interest rate tells you what borrowing costs. The initial repayment rate tells you how quickly you pay down the loan balance.

A useful rule of thumb is:

The monthly payment should be safe, the repayment speed should be meaningful, and the remaining balance after the fixed-rate period should be manageable.

To compare scenarios in German Immo Flow, keep the displayed loan amount, interest rate and all purchase assumptions unchanged, then save separate versions with 2%, 3% and 4% initial repayment. Compare the monthly payment, remaining balance and total interest. The result is a planning aid, not a financing offer.
