3 proration methods
Actual days
rent ÷ days in month × days
The most common approach. The daily rate changes with month length: 28 to 31 days.
365-day year
rent × 12 ÷ 365 × days
One fixed daily rate all year. Some leases and property managers use it.
30-day month
rent ÷ 30 × days
Every month counts as 30 days, so a full month is always full rent. Used in banker's-style accounting.
Your lease decides which one applies. When it is silent, ask your landlord for their formula in writing.
Prorated rent FAQ
How do I calculate prorated rent?
Divide the monthly rent by the number of days in the month to get a daily rate, then multiply by the number of days you occupy the unit. Example: $1,500 rent, move in September 20, 11 of 30 days: $1,500 ÷ 30 × 11 = $550.00.
Is a landlord required to prorate rent?
It depends on your lease and on state law. Many leases set the method and the dates, so read the proration or move-in clause and ask your landlord in writing how they calculate it. State rules differ; see our state-by-state pages. State tenant laws
Which proration method is cheapest?
It depends on the month. In a 31-day month the actual-days method has the lowest daily rate (rent ÷ 31). In a 30-day month the 365-day method is slightly lower (rent × 12 ÷ 365, about rent ÷ 30.4). The 30-day method always uses rent ÷ 30, so it costs more per day than actual-days in a 31-day month. In February, actual-days has the highest daily rate. The table above compares all three for your dates.
How is prorated rent calculated when moving out?
Count from the 1st of the month to your last paid day, inclusive, and multiply by the daily rate. Moving out on the 10th of a 30-day month at $1,500 is 10 days: $1,500 ÷ 30 × 10 = $500.00. Check your lease for the date the tenancy actually ends.
Does prorated rent apply to the security deposit?
No. The deposit is a separate amount and is not prorated by the number of days you stay. For when it must be returned, see the deposit deadline calculator. Deposit deadline calculator
