How do you calculate prorated rent?
Divide the monthly rent by the number of days in the month to get a daily rate, then multiply by the number of days the tenant occupies the unit that month. Some landlords use a flat 30-day month instead of the actual number of days.
Which proration method should I use?
Both the actual-days and 30-day methods are common. What matters most is that your lease states the method and you apply it consistently. Some jurisdictions require a specific approach, so check your local rules.
Does a move-in on the 1st get prorated?
No. A tenant who moves in on the first day of the month occupies the whole month and pays the full rent. Proration only applies to partial months.
