How will my new rent be calculated?

Your rent is calculated according to the legal rules. Every month, the government determines the increase in life expectancy in the so-called health index. That index indicates how much more expensive products and services have become over time.

You can find the starting index, the index that was applicable at the start of your rental agreement, in your rental contract (usually in article 4). We multiply your rent by the new index, and divide it by this starting index. In this way, we obtain the new rent. 

Suppose you signed a tenancy agreement last year for 750 euros per month, and the starting index was 100 then. If one year later the index is 102, the new rent is calculated as follows: (750 x 102) / 100 = 765 euros.
