1. What is the IRL Index?

The IRL (Indice de Référence des Loyers) is the official reference index used in France to calculate annual rent increases. In Montreal, France, landlords can increase rent based on this index, which reflects inflation and construction costs.

2. How Rent Increase is Calculated

The calculation uses the formula:

Where:

• Old Rent — Current monthly rent amount in EUR
• IRL — The annual reference index percentage

Example: For an old rent of €800 with IRL of 2.5%, the new rent would be €800 × 1.025 = €820.

3. Legal Framework in Montreal, France

Details: The rent increase is typically applied annually on the lease anniversary date. Landlords must provide proper notice (usually 3 months) and cannot exceed the IRL percentage unless property improvements justify a higher increase.

4. Using the Calculator

Tips: Enter your current rent in EUR and the applicable IRL percentage. The calculator will show the new rent amount after the increase.
