Prorated Rent Calculator

How the prorated rent calculator works

Prorated rent charges a tenant only for the days they occupy a unit during a partial month, such as a mid-month move-in or move-out. Enter the full monthly rent, the number of days in that month, and how many days the tenant occupies the unit. The calculator returns the daily rate and prorated amount due.

Prorated rent is common when leases start or end mid-month. To compare rent offers after concessions, use the net effective rent calculator. Landlords often require income at three times monthly rent, which you can check with the 3x rent calculator. For a broader affordability view, try the rent affordability calculator. Commercial tenants with longer terms can model lease costs in the commercial lease calculator.

Prorated rent formulas

The daily rate divides full monthly rent by the number of days in the billing month. Prorated rent multiplies the daily rate by occupied days, capped at the full month:

Worked example: $1,500 rent, 10 days in a 30-day month

A tenant moves in on the 21st of a 30-day month and occupies the unit for 10 days at $1,500 monthly rent:

1. Daily rate: $1,500 / 30 = $50.00 per day
2. Prorated rent: $50.00 x 10 days = $500.00
3. Unoccupied portion: $1,500 - $500 = $1,000.00

Lease agreements may use a different proration method (actual days vs a flat 30-day month). Confirm the method in your lease before paying. The net effective rent calculator helps compare offers when free rent or concessions apply.

When prorated rent applies

Proration typically applies at move-in when a tenant starts mid-month, at move-out when leaving before the last day, or when a lease is terminated early. Some landlords charge full month rent regardless of move-in date. Always review your lease and local tenant laws.
