Frequently asked questions
How is prorated rent calculated?+
Divide the monthly rent by the number of days in the month (or by 30, or annual rent by 365), then multiply by the number of days the tenant occupies the unit. The most common method divides by the actual days in the month.
Which proration method should I use?+
Most landlords use the actual-days method (rent ÷ days in month). Whatever you choose, state it in the lease so it's consistent and enforceable.
Is the calculator free?+
