Actual Days vs 30-Day Method for Prorated Rent
When calculating prorated rent for a partial month, landlords generally select one of two accounting methods: the actual days method or the 30-day average method. While both methods split monthly rent into daily charges, the final dollar total can differ depending on the month you move in.
Understanding how these two options function helps you double-check your lease agreement and ensure you are being billed fairly.

Option 1: The Actual Days Method
The actual days method divides your monthly rent by the exact number of calendar days in the current month (28, 29, 30, or 31). This is the most common approach used by private landlords and property managers.
For example, if your rent is $1,500.00 and you move in on February 15th (a 28-day month):
- Daily rate: $1,500 / 28 = $53.57 per day
- 14 days occupied: 14 x $53.57 = $750.00
If you move in on July 15th (a 31-day month) at the same $1,500 rent:
- Daily rate: $1,500 / 31 = $48.39 per day
- 17 days occupied: 17 x $48.39 = $822.63
Option 2: The 30-Day Standard Method
The 30-day standard method assumes every month has 30 days regardless of calendar length. The daily rate stays fixed all year at monthly rent divided by 30.
Using the same $1,500 rent example, your daily rate is always $50.00 ($1,500 / 30). Moving in for 14 days in February costs $700.00 under this method, saving you $50 compared to the actual days method.
Which Method Is Better for Tenants?
The 30-day method benefits tenants moving in during short months like February. Conversely, the actual days method offers lower daily rates during 31-day months such as July, October, or December.
