When a tenant moves into or out of a property in the middle of the month, rent for that month is only due for the actual period of occupancy. This is known as prorated rent (prorata temporis). The calculation consists of working out a daily rent, then multiplying it by the number of days of occupancy.
The formula is as follows:
Prorated rent = monthly rent × days of occupancy / number of days in the month
The same calculation applies to service charge provisions. For a move-in, count the days from the arrival date (inclusive) to the end of the month. For a move-out, count the days from the first day of the month to the departure date (inclusive).
For a rent of €900 including charges and a move-in on 10 July, the tenant occupies the property for 22 of the 31 days in the month:
900 × 22 / 31 = €638.71
The most common method, and the one generally upheld by French courts, uses the actual number of days in the month (28, 29, 30 or 31). Some landlords use a flat 30-day basis for every month: this method is tolerated as long as it is applied consistently, but the actual-days method remains the recommended one.
