Did your landlord send an update letter, or are you a landlord updating a rent in Portugal? In 2026, lease rents can be updated by the official coefficient of 1.0224, a 2.24% increase. This calculator applies the coefficient to your current rent and shows the new rent, the increase per month and per year, and the sum step by step, including the catch-up of coefficients from earlier years that were never applied.

About renting calculators
Renting a home involves sums on both sides of the contract: how much the State pays towards a young tenant’s rent, how much the rent can rise each year, what the landlord pays in tax on the rents and what is left at the end. These calculators handle those sums from the official rules, starting with the annual rent update coefficient the INE publishes. They link to the rental income tax and rent receipt calculators so you can see the full picture. They are educational estimates that do not replace professional advice. Each calculator explains the sum it does and links to the article that goes deeper.
