What is prorated rent? 

Imagine yourself moving in an apartment. You already talked with your landlord about the move in date, say June 15. In most cases, rents get charged on a monthly basis and it is not fair that the landlord charges his tenant the full rent for June. Therefore, you as a tenant should only pay


How do you calculate prorated rent? 

Even without using a prorated rent calculator, performing the calculation manually is a really easy job. There’s nothing to worry about when making the calculations. Just follow these simple steps:

  • Start with the date when you moved in to your new place. Let’s assume the day is the 15th of June.
  • Check the number of days for that particular month. June, of course, has 30 days. Write down that number.
  • Count how many days you will live in the apartment for that month. Your count should start on the 15th, the 16th should be day 2, and so on. After counting, you will come up with 16 days.
  • Before moving in, you should already know from your landlord how much is the rent for each month. For our example, let’s set it at $600.
  • Divide the rent for each month by the number of days for that month. Therefore:

            $600 / 30 = $20 each day

  • Lastly, multiply this amount by how many days you will live in the apartment:

            $20/day * 16 days = $320.

Although you can do these calculations manually, using a prorated calculator will make the job a lot easier and faster. Simply enter the required data and you’ll have the information that you need in an instant.


What does it mean to have rent prorated? 

For those who are not familiar with prorated rent, it is simply how much money that a landlord would charge when the renter is only going to occupy a place for a short period of time such as for a month, a week, and such. In other words, it is how much the landlord charges for how many days the tenant will occupy the unit.

In most cases, the landlord would base the price on the rate per month and not on a daily rate, the latter being more expensive. Prorated rents by the day are most practical for tenants who either move in or out at an odd time of the month or plans to sublet the apartment to another person.


Is prorated rent based on 30 days? 

Prorated rent refers to the amount tenants pay the landlord where the tenant will not use the property for an entire month. However, he will still pay for a partial rent. The number of days of occupancy can vary.

First, divide the monthly rate by 30, of course, assuming that the month in question has 30 days. Then multiply this quotient by how many days the tenant will pay for the rent. Let’s look at an example:

Rent per month= $900.00

Days in the month = 30 days

Days of occupancy = 12 days

Rent per day = $900.00 / 30 days = $30.00 / day


Prorated Rent = $30.00 x 12 = $360.00


How to prorate rent? 

There are two methods to calculate prorated rent if you don’t plan to use a prorated rent calculator. The good news is that both are very simple so you can make the calculations yourself.

Calculating the prorated rent using the number of days in each year

This is a popular and more accurate method for those who have a lease which lasts for a whole year. Unfortunately, this method has a tendency to confuse tenants. Still, it’s worth learning about. Here is the formula for this type of prorated rent.

PR = ((MR * NM) * NT) / ND


PR refers to the Prorated Rent

MR refers to the Monthly Rent

NM refers to the Number of months in a year

ND refers to the Number of days in a year

NT refers to the Number of days the tenant will pay for.


So, let’s assume that:

MR = $1,500 and your move-in date is June 16


PR = $1,500 * 12 *15  / 365 =  $739.73


This calculation applies for a month with 30 days. Assuming the month has 31, you may get a higher result in monthly calculations.

Calculating the prorated rent using the number of days in each month

This is comparatively an easier method in calculating prorated rents. Here is the formula:

PR = ((MR/NM) * NT) / ND


PR refers to the Prorated Rent

MR refers to the Monthly Rent

ND refers to the Number of days in a month

NT refers to the Number of days the tenant will pay for

Let’s assume that:

MR = $1,500 and your move-in date is July 17


PR = ((1500/31) * 15)/31 = $725.80

Here are benefits in calculating using this method:

  • First, it’s more accurate. If you have been renting an apartment for some time, you should know that not all of the months have the same days.
  • Second, it’s easier to understand. Most tenants could only think of the present. Most of them are first-timers as tenants and live only from paycheck to paycheck. They’re not yet that familiar with long-term responsibilities.
