Calculation of rent increase (private housing sector)

This tool calculates rent adjustments in the private housing sector according to the consumer price index (CPI) of Statistics Netherlands (CBS). The annually permitted rent increase (or decrease) can be determined easily this way. It concerns rents which at the start of the tenancy agreement exceed the so-called rent liberalisation threshold, which isolates the private housing sector from the social housing sector. As of 1 January 2017, this limit stood at 710.68 euros. It is also possible to use the tool to calculate the increase in rents of commercial buildings. Your tenancy agreement mentions how the rent will be increased annually. If you wish to perform more than one calculation or adjust your selection, press Ctrl/F5 first to refresh the view.
The maximum rent increase in the social housing sector is set by the Ministry of the Interior and Kingdom Relations (BZK). More information can be found on rijksoverheid.nl/huurverhoging (Dutch only).

Your tenancy agreement mentions the series used to calculate the rent increase. In most cases, this is ‘All households’ (Alle huishoudens). The ‘Employees low’ (Werknemers laag) series was terminated as of 2003. The PDF document in the ‘Downloads’ section at the bottom of the page explains what you should do if your contract tells you to use the ‘Employees low’ series.

Your tenancy agreement mentions the rent to be used as a basis: the rent paid most recently or the rent paid at the start of the contract (initial rent). As a decimal separator, you need to use either a .(period) or a ,(comma), depending on your browser settings. If it is not possible to use a period, please select a comma instead (and vice versa).

Your tenancy agreement mentions the period to be used in calculating the new rent. This is either a month or a year. If the period refers to a month, this is usually the month which is four months prior to rent adjustment. If the period is a year, it is usually the year prior to the year in which the rent is adjusted.

Your tenancy agreement mentions which month or year is used as the base period for your rent.

If you selected a month in the previous step, you should do the same here. In case your contract mentions the most recently paid rent as a basis, this is usually the month which is one year and 4 months prior to the month in which the adjustment is made. In case your contract mentions the initial rent as a basis, this is usually the month which is 4 months prior to the start of the first rental period.

If you selected a year in the previous step, then the same applies here. In case your contract mentions the most recently paid rent as a basis, you should fill in the year prior to the year stated in step 3. In case your contract mentions the initial rent as a basis, this is usually the year prior to the year of the first rental period.

The base year is automatically calculated by the rent calculator, so please leave as it is. Even if stated otherwise in your contract, the base year presented by the calculator should be used, as number series will stop at a certain point. This is why tenancy agreements often state that when CBS stops publishing the series/index figure indicated, you need to switch to the series/index figure succeeding these series according to CBS. By having the rent calculator select this automatically, you comply with this clause in your contract.
