Monthly payment, true cost (effective annual rate), fixed or variable rate risk and how much you can afford, with the rules that apply in Switzerland.

For a mortgage of 800,000 CHF over 30 years at 1.8%, the monthly payment is about 2,877.59 CHF. Change the amount, term and rate in the calculator above to see your own payment.
The effective annual rate includes fees and required costs on top of interest. In our example with typical fees the effective annual rate is 1.81% while the nominal rate is 1.8%. Compare loans by the effective annual rate and by the total amount you repay.
SARON mortgages follow the Swiss average overnight rate, which is near 0% in October 2026 after the SNB cuts, plus a bank margin. They are cheapest today but move with every SNB decision. Fixed mortgages lock the rate for 2 to 15 years. If rates rose by 2 points, the payment in our example would go up to 3,727.66 CHF. A fixed rate protects you from that risk, a variable rate can be cheaper when rates fall.
Swiss banks calculate with a 5% imputed rate, 1% maintenance and the required amortisation, and these costs must not exceed one third of your gross income. You also need at least 20% equity. The calculator applies this test when you enter the property value and your gross monthly income.
Swiss mortgages are among the cheapest in Europe, but banks test affordability with an imputed rate of 5%, far above today's rates. You need at least 20% equity, and the part of the mortgage above two thirds of the property value must be repaid within 15 years. Consumer loans are capped at 10% interest by law.
The nominal interest rate only covers interest. The effective annual rate adds the fees and costs you must pay to get the loan, such as processing fees, account fees and required insurance, and turns everything into one yearly percentage. Two loans with the same interest rate can have very different effective annual rate. When you compare offers for the same amount and term, the lower effective annual rate is usually the cheaper loan.
A fixed rate keeps your payment the same for an agreed period, so you know exactly what you pay. A variable rate is a reference rate (for example Euribor) plus the bank's margin. It is often lower at the start, but your payment rises when the reference rate rises. Use the stress test above to see your payment if rates go up by 1, 2 or 3 points, and only choose variable if you could still pay that.
With equal payments (annuity) the monthly amount stays the same, and at the start most of it is interest. With equal principal the first payments are higher but fall every month, and you pay less interest in total. Switch the repayment option in the calculator to see the difference.
Look beyond the monthly payment. Add up interest, upfront fees, monthly account and insurance costs, valuation and notary costs. A longer term lowers the payment but increases the total interest a lot. The line "cost per 100 borrowed" shows how much you pay for every 100 you borrow.
Paying off part of the loan early saves interest. Many countries limit what banks may charge for it, and variable-rate loans can often be repaid without a fee. Read the early repayment clause before you sign.
Typical mortgage at today's average rate, equal monthly payments, without fees. Interest rate: 1.8%.

Fixed-rate mortgages can usually only be ended early against a prepayment penalty that covers the bank's lost interest. SARON mortgages can often be ended at the end of a period. Consumer loans can be repaid early at any time without a penalty.
In October 2026 Swiss 10 year fixed mortgages cost about 1.5% to 2.1%, and SARON mortgages about 0.8% to 1.2%. Personal loans cost up to the legal maximum of 10%, often 5% to 9%.
