How it works

When a tenant moves in mid-month, most landlords charge only for the days they occupy the unit. Check your lease and local rules for the required method.

The formula

Daily rate = monthly rent ÷ divisor (days in month, 30, or 365/12)
Prorated rent = daily rate × days from move-in through month end (inclusive)

FAQ

Which method should I use?

The actual-days method is the most common and easiest to explain. Use whatever your lease specifies.
