Frequently asked questions
How is prorated rent calculated?
The most common method divides the monthly rent by the total number of days in that month to get a daily rate, then multiplies by the number of days the tenant will occupy the unit. For example, $1,500 rent in a 30-day month with a move-in on the 16th means 15 days of occupancy: ($1,500 / 30) × 15 = $750.
Does this use actual days in the month or a 30-day 'banker's month'?
This calculator uses the actual number of days in the specific calendar month the tenant moves in — so February (28 or 29 days) and a 31-day month are each handled correctly. Some leases use a flat 30-day 'banker's month' instead; check your lease for which method applies.
Do I count the move-in day itself?
Typically yes — the day the tenant takes possession and moves in is counted as a day of occupancy. This calculator includes the move-in day through the last day of the month.
Can PropVecto handle prorated move-in charges automatically?
Yes. PropVecto lets you set a prorated amount for a tenant's first partial month, then charges full monthly rent thereafter — so move-in billing is handled without manual math.
