Prorated Rent Calculator
Calculate daily rent, prorated rent, occupancy percentage, and unused rent based on full-period rent, billing days, and occupied days. Prorated Rent Calculator helps tenants, landlords, and property managers fairly determine charges for partial rental periods.
Highlights
- Calculate accurate daily rent from the full-period rental amount.
- Determine prorated rent for partial billing periods.
- Estimate unused rent for unoccupied days.
- View the tenant’s occupancy percentage.

How Prorated Rent Calculator Works?
The Prorated Rent Calculator allocates a full-period rent amount across the number of days in the billing period, then charges only for the occupied days. It accepts the full-period rent, billing period length, and occupied days. Occupied days should not exceed the billing period days.
First, the calculator determines the daily rent by dividing the full-period rent by the total billing days:
The prorated rent is the daily rent multiplied by the number of occupied days. Equivalently, it is the full-period rent multiplied by the fraction of the period occupied:
Unused rent represents the portion assigned to days that were not occupied:
Occupancy percentage shows what share of the billing period was occupied:
| Input or output | Example |
|---|---|
| Full-period rent | 2000 |
| Billing period | 30 days |
| Occupied days | 15 days |
| Daily rent | 66.6667 |
| Prorated rent | 1000 |
| Unused rent | 1000 |
| Occupancy percentage | 50% |
The rent outputs use the selected supported currency, including USD, CAD, EUR, GBP, AUD, NZD, INR, JPY, or CHF. The percentage output is displayed as a percent.
Practical Use Cases
Tenants moving into a property can estimate the amount owed when their lease begins partway through a billing period. For example, entering a full-period rent of 2000, a 30-day billing period, and 10 occupied days produces a charge based on one-third of the full-period rent.
Tenants moving out can use the calculator to check a final partial-period charge. If they occupy a property for 20 of 30 billing days, the calculator assigns two-thirds of the full-period rent to the occupied period and identifies the remaining unused rent.
Landlords can calculate consistent move-in or move-out charges instead of applying an arbitrary daily amount. The result provides the daily rent, prorated rent, unused rent, and occupancy percentage for documenting the billing decision.
Property managers can use the calculator when preparing statements for partial-month occupancy, lease changes, or unit turnovers. Entering the agreed billing period and billable occupied days creates a repeatable calculation for different properties and tenants.
Rental accounting teams can use the outputs to reconcile collected rent with the occupied portion of a billing period. The prorated rent and unused rent should add back to the entered full-period rent, subject to displayed rounding.
Accuracy and Limitations
The calculator accurately applies a straight-line daily allocation using the entered full-period rent, billing period days, and occupied days, with billing periods supported from 1 to 366 days and occupied days from 0 to 366 days. It assumes every day in the selected billing period has the same rental value and that occupied days are billable calendar days; it does not account for lease-specific conventions, different rates for individual dates, grace periods, concessions, deposits, fees, taxes, utilities, late charges, or rent-free days. Currency values may be displayed with rounding, so multiplying a rounded daily-rent result by the occupied days can differ slightly from the calculator's underlying prorated result.
Quick Examples
Example #1: Half-Month Move-In
Calculates prorated rent for a tenant occupying a unit for half of a 30-day billing period.
Example #2: Mid-Month Move-Out
Determines the rent owed and unused rent when a tenant occupies 10 days of a 31-day billing period.
Example #3: Short-Term Occupancy
Estimates prorated rent for a brief 7-day occupancy during a 28-day billing period.
