Provide Move-Out Date (If Applicable)
If you're calculating for a move-out scenario, enter the date you plan to vacate the property. Leave blank if only calculating move-in proration.
Select Your Billing Cycle
Choose whether your rent is based on the calendar month (1st to last day) or a specific date each month (like the 5th to the 4th of the next month). For converting between different units, try our unit converter.

Frequently Asked Questions
Prorated rent refers to the calculated amount a tenant pays when they don't occupy a rental property for a full billing cycle. Instead of paying for an entire month, the rent is proportionally adjusted based on the number of days the tenant actually occupies the unit. This commonly occurs when moving in or out mid-month.
To prorate rent, follow these steps:
- Determine the monthly rent amount
- Calculate the daily rate by dividing the monthly rent by the number of days in the specific month
- Count the number of days the tenant will occupy the property
- Multiply the daily rate by the number of occupancy days
To calculate prorated rent manually:
Formula: (Monthly Rent / Number of Days in Month) × Number of Occupancy Days
Example: If monthly rent is $1,500, moving in on the 15th of a 30-day month:
Daily rate = $1,500 / 30 = $50 per day
Occupancy days = 16 (from 15th to 30th inclusive)
Prorated rent = $50 × 16 = $800
Pro rata rent calculation follows the same principle as prorated rent. The term "pro rata" is Latin for "in proportion," meaning you're calculating the proportional amount of rent based on the actual days of occupancy. Use our calculator above for quick and accurate pro rata rent calculations without the manual math.
Laws regarding prorated rent vary by state and province. In many jurisdictions, landlords are required to offer prorated rent when tenants move in mid-month, but it's always best to check local regulations and your lease agreement.
While the basic calculation method is similar, commercial leases often have different structures and provisions. This calculator is designed primarily for residential rentals, but may provide a rough estimate for commercial properties.
