Prorated Rent Calculator

Calculate the prorated rent amount for a move-in or move-out date based on your monthly rent and chosen proration method.

Your details

The full monthly rent amount for the property.

The date you are moving into or out of the rental property.

Is this for a move-in (prorated first month) or a move-out (prorated last month)?

The method used to calculate the daily rate. 'Days in Month' is most common. '365 Days' divides the annual rent by 365. '30 Days' assumes every month has 30 days.

Optional. Number of free weeks offered as a promotion. These days are subtracted from the days you owe rent for.

Keep in mind
  • This calculator provides common proration methods. Your lease agreement may specify a particular method, which takes precedence.
  • The 'Days in Month' method calculates the daily rate as (Monthly Rent) / (Number of Days in that Specific Month).
  • Free weeks are applied by subtracting the corresponding number of days from the prorated days. If free days exceed prorated days, the billable amount is zero.

Residential Lease Agreement

What is Prorated Rent?

Prorated rent is a partial rent payment for the period you live in a rental property when your move-in or move-out date does not align with the standard lease cycle (typically the first of the month). Instead of paying for a full month you didn't fully occupy, landlords often calculate a reduced amount based on the exact number of days you will be a tenant.

How is Prorated Rent Calculated?

The calculation follows a simple principle: (Daily Rent Rate) x (Number of Days Occupied). However, the method for determining the daily rate can vary. The most common methods are:

  • Days in the Specific Month: The monthly rent is divided by the total number of days in the month of the move-in/move-out. This is the most precise and common method.
  • 365 Days (Annualized): The yearly rent (monthly rent x 12) is divided by 365 to get a consistent daily rate, regardless of the month.
  • 30 Days: A simplified method where every month is assumed to have 30 days. The daily rate is the monthly rent divided by 30.

Your lease agreement should specify which method is used. If it doesn't, state law or local custom may apply, but the "Days in Month" method is generally considered fair.

Example Calculation

Imagine your monthly rent is $1,800 and you move in on October 15th. October has 31 days.

  • Step 1: Find Daily Rate (Days in Month method): $1,800 / 31 days = $58.0645 per day.
  • Step 2: Find Days to Prorate: From October 15th to October 31st inclusive is 17 days.
  • Step 3: Calculate Prorated Rent: $58.0645 x 17 days = $987.10.

Your prorated rent for your first partial month would be $987.10, followed by the full $1,800 on November 1st.

Common Scenarios

Move-in Mid-Month

This is the most frequent use for prorated rent. You pay for the remaining days of your first month and then begin paying full rent on the 1st of the following month.

Move-out Before Month End

If you vacate before the last day of the month, you may only owe rent up to your move-out date. The landlord would then prorate your final month's payment.

Promotions with Free Weeks

Some landlords offer "one month free" or "two weeks free" as a move-in incentive. This is often applied by deducting the equivalent number of free days from your first (or another) month's billable period.

Next Steps: Document Your Agreement

Once you've calculated the prorated amount, it's crucial to document it in your lease. Use a Residential Lease Agreement to clearly state the monthly rent, the lease start date, and any prorated amount for the first month. This prevents misunderstandings and ensures both you and your landlord are protected.

Frequently asked questions

What is the most common method for calculating prorated rent?

The 'Days in the Month' method is the most common and generally considered the fairest. It divides the monthly rent by the exact number of days in the specific month of the move-in or move-out.

Can my landlord use a different proration method?

Yes, but the method should be clearly stated in your lease agreement. If it's not specified, you can negotiate which method to use. State laws sometimes have default rules, but they vary.

How do free weeks or a 'free month' promotion work with prorated rent?

Free periods are typically applied by reducing the number of days you are charged for. For example, two free weeks (14 days) would be subtracted from the number of prorated days you owe in your first month. Our calculator includes this option.

Is prorated rent required by law?

There is no universal federal law requiring prorated rent. It is a matter of contract and, in some cases, state or local law. Most landlords offer it as a standard practice for mid-month move-ins/outs to be fair and attract tenants.

What if I move in on the first day of the month?

If you move in on the 1st, you owe the full month's rent. Proration is only necessary when occupying the unit for part of a billing cycle.

Should I get a receipt for my prorated rent payment?

Yes, you should get a receipt for any rent payment. A Rent Receipt provides proof of payment, which is useful for your records and in case of any future disputes.
