What Is Prorated Rent?

"In a lease agreement, prorated rent specifies the amount a tenant must pay the landlord for the exact number of days they occupy the rental unit."

Prorated rent is based on the monthly rent. If a tenant stays only part of the month, they pay the corresponding percentage of the monthly rent.

How To Calculate Prorated Rent?

Follow these steps to calculate prorated rent manually:

Divide the monthly rent by the total number of days in the month to determine the daily rent
Multiply the daily rent by the number of days the tenant occupies the property
The result is the prorated rent amount the tenant owes

Mathematically:

Prorated Rent = (Monthly Rent ÷ Number of Days in Month) × Number of Prorated Days

Example:

Henna (a Texas resident) pays $1,450 per month for her current house and plans to move on July 14 to a new house with $1,200 monthly rent.

Solution:

Using the “day-in-a-specific-month” method:

Current Landlord:

Prorated Rent = 1450 ÷ 31 × 13 ≈ 46.774 × 13 ≈ $608.06

Next Landlord:

Prorated Rent = 1200 ÷ 31 × 18 ≈ 38.709 × 18 ≈ $696.76

Alternative Formulas:

Days In A Year Method:

Using 365 days in a year:

Prorated Rent = (Monthly Rent × 12 ÷ 365) × Number of Days Rented

Days In An Average Month Method:

Calculate the average number of days in a month:

Average Days = (31 + 29 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31) ÷ 12 ≈ 30.42

Prorated Rent = (Monthly Rent ÷ 30.42) × Number of Days Rented

Banker’s Month Method:

Banks often use a standardized 30-day month for all calculations:

Prorated Rent = (Total Rent ÷ 30) × Number of Days Rented

Should First Month Rent Be Prorated?

It depends on your lease and landlord policy. If both parties agree, the first month can be prorated. Otherwise, there is no legal requirement for landlords to prorate rent.

How Much Should You Spend on Monthly Rent?

As a general guideline, spend about 30% of your monthly income on rent. Include additional costs like security deposits, renter’s insurance, and move-in expenses.

Why Should I Prorate Rent?

Prorating rent ensures you only pay for the days you occupy the rental unit if you move in or out mid-month.
