Rents in Portugal may increase up to 2.56 percent in 2027: What awaits tenants?

House rents in Portugal can be increased by up to 2.56 percent in 2027. The rate, which emerged with the finalization of August inflation data, is higher than the 2.24 percent rent update applied this year.

However, the rate of 2.56 percent does not mean that all rents will automatically increase at this rate on January 1. In order for the increase to be implemented, the legal procedure must be followed and the situation of every lease agreement may not be the same.

According to the final data of Instituto Nacional de Estatística (INE) for August, the average change of the consumer price index excluding the housing item in the last 12 months was 2.56 percent. This indicator forms the basis for calculating the coefficient used in the annual rent update in Portugal.

How much can 1,000 euros of rent be?

If the rate of 2.56 percent is applied exactly, the calculation is quite simple.

For a house with a monthly rent of 1,000 euros, the maximum increase is 25.60 euros. The new rent could rise to 1,025.60 euros.

A rent of 800 euros increased by approximately 20.48 euros to 820.48 euros; A rent of 1,200 euros can increase by 30.72 euros to 1,230.72 euros.

This means an additional cost of 307.20 euros per year for a rent of 1,000 euros and 368.64 euros for a rent of 1,200 euros.

The increase is not automatic

There is an important detail here for tenants.

The announced 2.56 percent is not an increase that the landlord must apply; appearing for annual update reference rate.

Additionally, the coefficient must be officially published in Diário da República. In accordance with the legislation, this is expected to be done by October 30.

If the landlord wants to implement the rent update, he must notify the tenant. The new amount can be applied not immediately after the notification is made, but after the required notification period has passed.

Therefore, a comment such as "all rents in 2027 will increase by 2.56 percent on January 1" is not correct.

An increase cannot be made on January 1 in every contract.

The start or last update date of the contract is also important in the annual rent update.

Annual updates to rent legislation in Portugal can generally be implemented after one year has passed since the previous rent determination or update.

Therefore, for example, in terms of the contract of a tenant whose rent is updated later in the year, the date when the new coefficient can be used may change accordingly.

Tenants need to look not only at the new figure reported to them, but also at the date of the contract and when the last rent increase was made.

higher than in 2026

The official rent update coefficient for 2026 was determined as 1.0224, that is, 2.24 percent.

The rate of 2.56 percent for 2027 therefore shows that the rate of increase has increased again.

According to official historical data from Portal da Habitação, rent updates have been quite volatile in recent years He watched.

The coefficient, which was 0.43 percent in 2022, increased to 2 percent in 2023. In 2024, it reached 6.94 percent due to the effect of the inflation wave. Then, it decreased to 2.16 percent in 2025 and 2.24 percent in 2026.

The rate of 2.56 percent calculated for 2027 is higher than the rates in the last two years, although it remains well below the extraordinary increase in 2024.

Why is it important for tenants?

The housing problem in Portugal is not only caused by annual rent increases. Especially in high-demand regions such as Lisbon, Porto and the Algarve, the prices demanded in new rental agreements are already high compared to the income of many households.

Therefore, although 2.56 percent may seem like a limited increase on paper, its impact in euro terms grows in households with high current rents.

For example, if the full rate is applied in a household paying 1,500 euros in rent, the monthly increase reaches 38.40 euros and the annual additional payment reaches 460.80 euros.

This may increase the overall pressure on household budgets, especially at a time when energy, food and transportation costs are also rising.

What should be checked if a notice of increase is received from the landlord?

The tenant must first check whether the applied rate is compatible with the official coefficient.

Then, the start date of the lease agreement, the date of the last update and when the notification was made should be checked.

For example, if the monthly rent is 1,000 euros, the standard annual rate of 2.56 percent The cost of the update is 25.60 euros. If an increase higher than this is requested, citing only the annual coefficient, the legal or contractual basis on which the increase is based should be examined separately.

The last step for the exact coefficient Diário da República

Although INE's August data has finalized the reference of 2.56 percent, the last step of the legal process has not been completed yet.

The annual rent update coefficient to be applied for 2027 must be published in Diário da República.

Therefore, the correct statement at this stage is “Rents in Portugal may increase by up to 2.56 percent in 2027.”

When the official coefficient is published, the figure to be applied to tenants and homeowners will be legally finalized.
