How much can rent go up in Portugal in 2027? The honest answer: we do not know for certain yet. The official coefficient is only published by INE (Instituto Nacional de Estatística, Portugal's national statistics institute) in October 2026. But there are already credible estimates based on inflation projections, and we can run concrete numbers.

Expected rent increase for 2027 (estimate)

Based on the Bank of Portugal's inflation projections · Official coefficient in October 2026

What is the current estimate?

Based on the macroeconomic projections for 2026 (Bank of Portugal, European Commission, IMF), a reasonable estimate for the 2027 INE rent update coefficient is +2.00% (coefficient 1.0200). This is an estimate, to be confirmed when INE publishes the official figure.

This figure sits in the middle of three possible scenarios:

Examples: how much rent will rise in 2027

Assuming the central estimate of +2.00%, these are the expected increases for typical rents:

Current rent New rent 2027 (est.) Monthly difference Per year
€500€510+€10+€120
€650€663+€13+€156
€800€816+€16+€192
€1,000€1,020+€20+€240
€1,200€1,224+€24+€288
Note The figures above assume a single 2027 update. If the landlord has accumulated unapplied coefficients from previous years, the final increase can be larger.

Estimate vs recent coefficients

For context, these are the actual figures from recent years:

The trend points to stabilisation around 2%, reflecting the return of inflation to the ECB's target levels.
