Sondertilgung: Should You Pay Off Your German Mortgage Early?

Note: This content is specific to the German banking market. In Germany, standard mortgage contracts usually include a Sondertilgung (Special Repayment) clause. This typically allows you to pay off 5% of the initial loan amount every year without paying the dreaded Vorfälligkeitsentschädigung (Prepayment Penalty). If you borrowed €400,000, you can pay an extra €20,000 each year for free. But should you?

The Math: Interest Rate vs. Investment Return

The decision is purely mathematical. Compare your mortgage interest rate with the return you can get on a safe investment (like a Tagesgeldkonto or fixed-term deposit). To make an informed decision, consider the following factors:

Your current mortgage interest rate

The return on investment for a safe savings option

The potential benefits of paying off your mortgage early, such as reduced interest payments and increased equity in your home

Scenario A: Old Mortgage (Low Rate)

Mortgage Rate: 1.5% (locked in 2020).

Savings Rate: 3.5% (available in 2025).

Verdict: DO NOT PAY.

If you put €20,000 into a savings account, you earn €700. If you put it into the mortgage, you save only €300 in interest. You lose money by amortizing. In this scenario, it makes more sense to invest your money elsewhere, as the return on investment is higher than the interest saved by paying off your mortgage.

Scenario B: New Mortgage (High Rate)

Mortgage Rate: 4.0% (locked in 2024).

Savings Rate: 3.0%.

Verdict: PAY.

Repaying the loan gives you a guaranteed, tax-free return of 4.0%. This beats most safe investments. In this case, using the Sondertilgung allowance to pay off your mortgage early is a good idea, as it provides a higher return than investing your money elsewhere.

The "Use It or Lose It" Rule

Crucial detail: The Sondertilgung allowance is usually not cumulative. If you don't pay the €20,000 in 2025, you cannot pay €40,000 in 2026. The allowance resets every year. This means that if you don't use the allowance in a given year, you will forfeit the opportunity to pay off an additional €20,000 of your mortgage without incurring a prepayment penalty.

Key Considerations

Before making a decision, consider the following key points:

Interest rates: Compare your mortgage interest rate to the return on investment for a safe savings option.

Sondertilgung allowance: Use the allowance to pay off your mortgage early if it provides a higher return than investing your money elsewhere.

Prepayment penalty: Avoid incurring a prepayment penalty by using the Sondertilgung allowance to pay off your mortgage early.

Equity and risk: Paying off your mortgage early can increase your equity in your home and reduce your risk for future refinancing rounds.

Benefits of Paying Off Your Mortgage Early

Paying off your mortgage early can have several benefits, including:

Reduced interest payments: By paying off your mortgage early, you can save money on interest payments over the life of the loan.

Increased equity: Paying off your mortgage early can increase your equity in your home, providing a sense of security and stability.

Reduced risk: Paying off your mortgage early can reduce your risk for future refinancing rounds, as you will have more equity in your home and a lower loan balance.

Conclusion

Check your mortgage contract for the Sondertilgung rate. If your loan interest is higher than what you can get in a savings account, use the allowance to the max. It builds equity and reduces your risk for the future refinancing round. Consider the following key takeaways:

Use the Sondertilgung allowance to pay off your mortgage early if it provides a higher return than investing your money elsewhere.

Compare your mortgage interest rate to the return on investment for a safe savings option.

Avoid incurring a prepayment penalty by using the Sondertilgung allowance to pay off your mortgage early.

Paying off your mortgage early can increase your equity in your home and reduce your risk for future refinancing rounds.
