Questions
What is prorated rent?
A partial month's rent charged when a tenant moves in or out mid-month, so they pay only for the days they actually occupy the unit.
How do you calculate prorated rent?
Divide the monthly rent by the number of days to get a daily rate, then multiply by days occupied. Actual-days: rent ÷ days in that month × days occupied. 30-day method: rent ÷ 30 × days occupied.
Is a landlord required to prorate rent?
Generally it depends on the lease — most states don't mandate proration, but leases commonly provide for it and it's standard practice for mid-month moves.
Which method should I use?
Whichever your lease specifies. Most leases use actual days; some use a 30-day month. The calculator shows both and the difference.
Does prorated rent include the move-in day?
Yes — the move-in day is customarily counted as an occupied day, since the tenant has possession from that day.
