Prorated rent receipt
Method: Exact Days in Month (Banker's Standard)
Monthly rent: $1,800.00
Actual days: monthly rent is divided by the selected month's 28, 29, 30, or 31 calendar days.
30-day commercial: every month is treated as 30 days, and dates on the 31st are treated as day 30.
Annual 365-day: monthly rent is annualized and divided by 365, then multiplied by actual occupied calendar days.
This calculator counts the selected handover day as billable and rounds only the displayed result. Confirm the lease's day-count convention, local law, deposit rules, and possession time.
For property-tax closings, use the applicable annual tax figure and follow the settlement statement's 365/366-day and closing-day rules.

There is no single method accepted everywhere. Actual days in the month is common for residential rent, while some leases or jurisdictions use a 30-day method. The signed lease and applicable local law control, so confirm both before collecting or refunding money.
It commonly does when the tenant receives possession that day. This calculator counts the selected move-in or move-out date as billable. A lease, handover time, or local rule may specify otherwise.
Under the actual-days method, divide monthly rent by 29 in a leap-year February and multiply by occupied days. The calculator detects 28- and 29-day Februaries automatically. The commercial method still uses 30 days.
The daily-rate principle is similar, but tax prorations often use an annual bill, a 365- or 366-day year, jurisdiction-specific due dates, and a negotiated closing-day convention. Use the closing statement and local rules for the final adjustment.
