How to calculate your maximum rent increase in Spain under new rules
If your rental contract is due to end and it’s time renew, there’s a new government calculator that tells you exactly how much your landlord is allowed to increase your rent by, within the constraints of Spain’s recently introduced housing decrees.
The Spanish government has updated its rent calculator, which is designed to help tenants figure out the rent increases in their contract according to the new housing laws.
The new housing decrees entered into force last week temporarily, but it’s worth keeping in mind that they still have to be approved by parliament, which is currently dissolved due to the snap election called for November 29th.
Spain’s temporary rental laws state that the cost of rent will be either be frozen or increased by a maximum of two percent. It will affect all residential lease agreements that are due to renew from now until December 31st, 2027.

You can find the new calculator here.
Firstly, you must put in the amount of rent that you pay according to your current contract.
Next, you need to click on the link on the page to find out if your rent exceeds the reference values for your area. For this, you will need to follow the link and enter your address as well as information such as the size of the property, its condition and energy rating.
Using this data, the website will display a price range. If you are paying above this price range, you click ‘sí‘, because you are paying a rental price higher than the reference values. If not, you click on ‘no‘.
Finally, you must insert the date that your current rental contract ends. Then click on ‘Calculada Subida Máxima’.

The website will state either that your contract cannot be subject to rent price updates, according to Royal Decree-Law 29/2026, or that it can and how much it is allowed to increase by.
For example, if you’re paying €1,200 per month it may tell you that your new rent can only be increased to €1,224.
Spain’s Housing Ministry website clarifies that the results are for informational and support purposes only, and are applicable as long as the data entered is applied correctly.
If your contract expired on or after October 8th 2026, you have the right to an extension.
In this case, the calculator will tell you that you can request an extension for up to two years.
The extension is valid up until December 31st 2028. The only requirement is that rent payments must have been made for the previous eight months, so it’s important you haven’t defaulted.
According to the new law, your landlord must accept this extension, unless they can prove that they need the property for themselves or their family members.
If you are just renting a room rather than the whole property, it’s important to note that the sum of the rents for the individual rooms cannot exceed the price of the whole property. The limits established by the housing law must also be in place.
This law applies to the so-called stressed residential areas, where rents are the highest and where they exceed 30 percent of the average income or they’re more than 3 percentage points above the Consumer Price Index.
This is the case in certain places in Catalonia, Galicia, Asturias, Navarre and the Basque Country. The measure cannot be applied in regions like Madrid, which hasn’t declared any stressed areas.
