How to Calculate Prorated Rent
When a tenant moves in on any day other than the 1st, you owe them a prorated amount — rent only for the days they actually occupy the unit.
Example: Tenant moves in on the 10th of a 30-day month. Rent is $1,500. Daily rate = $50.00. Days occupied = 21. Prorated rent = $1,050.00.

Frequently Asked Questions
How is prorated rent calculated?
Divide the monthly rent by the number of days in the move-in month. Then multiply by the number of days the tenant will occupy the unit that month (from move-in day through the last day of the month).
What is the daily rent formula?
Daily Rate = Monthly Rent ÷ Days in Month. For example, if rent is $1,500 and the month has 30 days, the daily rate is $50.00.
Do landlords have to prorate rent?
Most states require landlords to prorate rent when a tenant moves in mid-month. Even where not legally required, it is standard practice and builds trust with tenants.
Should I use a 30-day month or actual days to prorate rent?
Using the actual number of days in the move-in month is the most accurate and tenant-friendly method. Some landlords use a flat 30 days — this calculator uses actual days, which is more widely accepted.
When is prorated rent due?
Prorated rent is typically due on the tenant's move-in date, separate from the first full month's rent (which is due on the 1st of the following month).
