Find out how much you can borrow and how much it will cost

To calculate a mortgage, simply enter the purchase price of the property, the amount of capital you have available and your household's gross annual income in the yellow fields and simply let our mortgage calculator do its job. This indicative mortgage calculator then works out how much you can borrow based on an assumed interest rate of 5% and how much you will actually pay based on the interest rate of your choice.

You can finance the remaining 15% of the purchase price with a 2nd mortgage (check exact % with your bank).

The interest rate is usually 1% higher than the interest rate of the 1st mortgage.

A representative example

If you wish to buy a property of CHF 1’000’000 and have CHF 200’000 of own funds, your total mortgage amount will be CHF 800’000.

To check your long-term ability to pay back the loan, banks will use an assumed interest rate of 5% for the 1st mortgage (CHF 32’500) + 5% for the 2nd mortgage (CHF 7’500) + 1% for maintenance and fixed costs (CHF 10’000) + an amortisation* of the 2nd mortgage (CHF 10’000). This brings you to a total of CHF 60’000 per year. This amount is multiplied by 3 (= CHF 180’000). To conclude: you need to have a gross annual income of CHF 180’000 to afford a property of CHF 1’000’000.

To find out how much the mortgage will actually cost, you need to apply the interest rate of your choice to the 1st mortgage amount, i.e. 1% (of 650’000 = CHF 6'500). For the 2nd mortgage you have to add 1% (2% of 150’000 = CHF 3'000). To this amount, you add the amortisation cost of the 2nd mortgage (CHF 10’000). The total mortgage cost will be equal to CHF 19’500 / year (= CHF 1’625 / month).

* The 2nd mortgage must be repaid within 15 years or by your retirement age, whichever comes sooner.
