How to Use the Prorated Rent Calculator

This calculator helps you figure out exactly how much rent you owe for a partial month. Enter your full monthly rent, the day of the month you plan to move in, and the number of days in that month.

The calculator divides your monthly rent by the number of days in the month to get a daily rate, then multiplies that by the number of days you will occupy the unit. For example, if you move in on the 15th of a 30-day month, you pay for 16 days (the 15th through the 30th).

Use this before signing a lease so you know exactly what your first payment will be. Landlords typically charge prorated rent for the partial month, then full rent starting the first of the following month.

About Prorated Rent

Prorated rent is the portion of a full month's rent that covers only the days you actually live in a rental unit. It applies when your lease starts or ends on a day other than the first of the month. Most landlords calculate proration by dividing the monthly rent by the total days in the month, then multiplying by the number of days you occupy the unit.

Some landlords use a fixed 30-day divisor regardless of the actual month length. If your landlord uses that method, select 30 as the "Days in Month" value to match their calculation.

Frequently Asked Questions

How is prorated rent calculated?

Prorated rent is calculated by dividing your monthly rent by the number of days in the month to get a daily rate, then multiplying that daily rate by the number of days you will be living in the unit. If your rent is $1,500 and you move in on the 15th of a 30-day month, your daily rate is $50 and you pay for 16 days, totaling $800.

Do landlords have to prorate rent?

There is no universal legal requirement for landlords to prorate rent. It depends on your lease agreement and local laws. However, most landlords do prorate rent for partial months at the start of a lease as a standard practice. Always check your lease terms to confirm how your landlord handles partial month charges.

Should I use actual days in the month or a standard 30 days?

It depends on your landlord's method. Some use the actual number of days in the calendar month (28, 29, 30, or 31), while others use a standard 30-day month for simplicity. Check your lease to see which method applies. This calculator lets you choose either approach.

Is prorated rent only for move-in, or does it apply at move-out too?

Prorated rent can apply at both move-in and move-out. If your lease ends mid-month, you may only owe rent for the days you occupied the unit. The same daily rate calculation applies. Check your lease agreement for specific terms about how your landlord handles partial months at the end of a tenancy.
