How Prorated Rent Works

Prorated rent is a partial month charge based on the days you actually occupy the unit. The most fair method is actual days (divides rent by the real number of days in the month). The 30-day method always divides by 30. The 365-day method divides annual rent by 365 and generally favors tenants.

Does the move-in day count?
Yes - if you have key access that day, you owe rent for it.
Can a landlord refuse to prorate?
Some states require proration; others do not. Check your lease and local tenant law.
Which method is most common?
Actual days is most common and most accurate. The 30-day method favors landlords in 31-day months and tenants in February.
