Frequently Asked Questions
How is prorated rent calculated?
Monthly rent ÷ days in month × days occupied. For example: $1,500 rent, moving in on the 15th of a 30-day month = $1,500 ÷ 30 × 16 = $800.
Do landlords have to prorate rent?
Most states do not require proration by law, but it is standard practice. Check your lease agreement — proration terms should be specified.
Which proration method is most common?
Calendar days (actual days in the month) is most common. Some landlords use a flat 30-day month or a banker's month (360 day year).
Is first month rent always prorated?
Only if you move in mid-month. If your lease starts on the 1st, you pay full rent. Some landlords charge full first month regardless.
