FAQ

Frequently asked questions

What is an extra repayment?

An extra repayment is an additional payment on top of the regular monthly payment. It reduces the outstanding balance and can reduce both interest cost and remaining term.

Does every extra repayment save money?

Mathematically, it usually reduces interest if there are no additional charges. Whether it is the best choice also depends on the contract, fees and alternative uses of the money.

Why does the calculator ask for the current monthly payment?

The monthly payment determines how quickly the loan is repaid. You can now choose whether the payment stays the same and the term becomes shorter, or whether the term stays the same and the payment falls.

Are the results binding?

No. The results are for guidance only. Your bank's calculation and your loan contract are what matter legally and financially.

When does an extra repayment have the strongest effect?

The earlier the balance falls and the higher the interest rate, the stronger the possible interest saving can be.
