Landlords can raise rents 2.56% in 2027. On a €1,000 rent that is €25.60 a month
INE closed the calculation on 31 August: inflation excluding housing came in at 2.56%, and that is the ceiling landlords may apply from 1 January. This year's figure was 2.24%.
The number is in. The inflation measure that sets Portugal’s annual rent update came in at 2.56%, according to the flash estimate INE published on 31 August. That is the ceiling landlords may apply to existing contracts from 1 January 2027, and it sits above the 2.24% used this year.
In money: a €1,000 rent becomes €1,025.60. On €800, you are looking at about €20.48 more a month. Not a shock. Still more than last year.
Why the number is not 3.3%
Headline inflation accelerated to 3.3% in August, and almost all of that came from fuel — the energy index rose 12.2%, against 8.7% the month before. That is not the calculation the law uses.
The rent coefficient comes from the twelve-month average of the consumer price index excluding housing, measured on 31 August. Two different indicators sharing a family name, and it is the second one that reaches your contract.
When it becomes official
A flash estimate is not the last word. INE publishes the definitive August CPI on 10 September, and the coefficient itself appears in the Diário da República by 30 October. Until then, 2.56% is the best available figure, and there is very little room left for it to move.
Nor is the increase automatic. A landlord has to give written notice within the period the law sets, and the rise follows your contract’s anniversary date rather than 1 January. Contracts with their own rules — supported-rent tenancies, or leases with negotiated escalation clauses — follow whatever is written into them.
What it says about the market
A 2.56% bump on existing tenancies sits awkwardly beside asking prices on new contracts, which are playing an entirely different game. That is the familiar split in Portuguese renting: sitting tenants move up gently, while anyone searching today pays the market rate. We covered the rents that cooled in June, and the gap has only widened since the rent brake ended on new contracts.
The price indices this calculation rests on are published by Statistics Portugal, which is where the confirmed figure will surface first, on 10 September.
For now the practical advice is dull and useful: check which month your lease renews. That, not January, is when the increase reaches you.
