The formula for the relative method of rent adjustment is based on a model developed by the Federal Office for Housing. If the reference interest rate rises by a quarter of one percent, this will result in a rent increase of 3%. In addition to the reference interest rate, 40% of the inflation rate (National Consumer Price Index) and cost increases may also be passed on to the rent. 

Tenancy law stipulates that the party initiating a change in the rent must be the one to take action. 

• If the reference interest rate drops, tenants may request a rent reduction. 
• If the reference interest rate goes up, landlords may communicate a rent increase.

Yes, landlords must inform tenants about the rent increase in good time using an official form. Key dates are the termination dates and deadlines agreed in the tenancy agreement or the customary local termination dates if these are not specified in the agreement. Please note the instructions for appeals on the rent adjustment form (reverse side).

Yes, you can appeal the rent increase to the arbitration authority within 30 days of receiving the letter from your landlord. See the appeal instructions on the rent adjustment form.

It’s impossible to say at this point. The reference interest rate is announced quarterly by the Federal Office for Housing.
Experts assume that the reference interest rate will continue to rise over the next few years.

Switzerland’s Federal Office for Housing publishes its reference interest rate quarterly, every 1 March, 1 June, 1 September and 1 December.

Any rent adjustment is regulated by law so it can only happen if the necessary requirements are met. As tenancy agreements for tenants are based on different conditions (e.g. reference interest rate), the potential for adjustments and the amount will also vary. 
For example, if different notice periods are agreed, there may also be different dates for rent adjustments.

Inflation is determined using the National Consumer Price Index. The starting point is the index indicated in the tenancy agreement or as known at the time of the last rent adjustment. This is then compared to the new index.
