How to Calculate Prorated Rent on Move-In Day

Moving into a new apartment rarely happens on the very first day of a calendar month. When your lease starts on the 15th or 22nd, you should only pay for the exact days you occupy the property. This partial payment is called prorated rent.

Calculating your partial payment is straightforward once you know your daily rental rate. Landlords typically use two main formulas to figure out this charge.

The Step-by-Step Prorated Rent Formula

To find your prorated rent amount, divide your full monthly rent by the total number of days in that month to get your daily rate. Next, multiply that daily rate by the number of days you will live in the apartment during that first month.

Prorated Rent = (Monthly Rent / Days in Month) x Days Occupied

Let us look at a real scenario:

First, calculate the daily rate: $1,800 divided by 30 days equals $60.00 per day. Then, multiply $60.00 by 14 days. Your prorated move-in rent comes to exactly $840.00.

When Do You Pay Prorated Rent?

Most landlords collect your prorated rent alongside your security deposit before giving you the keys. However, if you move in during the final week of a month, some property management companies require full payment for the upcoming month plus the prorated days upfront.

Always review your lease agreement to confirm which calculation method your landlord specifies. You can run custom dates and rent amounts anytime with our free Prorated Rent Calculator.
