Enter the current monthly rent and choose the update: the 2026 legal coefficient is 1.0224 (+2.24%). If the landlord skipped updates in earlier years, up to three coefficients can be applied at once. If the contract sets its own update criterion, choose "Another percentage" and enter the value.
| Current monthly rent | €800.00 |
| After the 2026 coefficient (×1.0224) | €817.92 |
| Increase per month | +€17.92 |
| Increase over 12 months | €215.04 |
The update is not automatic: the landlord communicates it by registered letter with acknowledgment of receipt, at least 30 days in advance, stating the coefficient and the new rent. It can only be demanded one year after the contract started or after the previous update.
The coefficients are the official INE ones, published by notice in the official gazette: 1.0224 for 2026, 1.0216 for 2025 and 1.0694 for 2024. The contract may set another update criterion, which prevails.
Estimate for lease contracts updated by the legal coefficient. Pre-1990 contracts still in the NRAU transition, supported (apoiada) rents and special regimes have their own rules and are out of scope.
Educational estimate, not advice. Confirm the coefficient and your contract's rules before sending or accepting a rent update.
