Calculate fair partial-month rent when a tenant moves in or out mid-month. Enter the monthly rent, days occupied and days in the month.
This uses the days-in-month method (monthly rent ÷ days in month × days occupied) — the most common and tenant-fair approach. Some leases use a flat 30-day month; check your agreement.
When a tenant moves in or out part-way through a month, they pay only for the days they occupy. Daily rate = monthly rent ÷ number of days in that month. Multiply by days occupied for the prorated amount. Always put the method in the lease to avoid disputes.
Divide the monthly rent by the number of days in the month to get a daily rate, then multiply by the days the tenant occupies the unit.
The fairest and most common method uses the actual days in that month. Some landlords use a flat 30-day banker's month — whichever you choose, state it in the lease.
A tenant moving in after the 1st, or moving out before month-end, pays prorated rent for their partial month.
