Prorated rent charges only for the days a tenant occupies the property. The answer depends on the daily rate the lease uses, so pick the method your agreement states.

Also called: Partial month rent calculator, Move-in rent calculator.

## Inputs
- Monthly rent (default 1500)
- First day of occupancy (default 2026-11-15)
- Last day of occupancy (inclusive) (default 2026-11-30)
- Daily rate method (options: Actual days in each month, Annual rent ÷ 365, 30-day month; default actual)
- Currency

## Results
- Rent due for the period
- Days occupied
- Daily rate (first month)
- Full months
- Partial months

## Formula

```
Full month = Rent;  Partial month = Days occupied × Daily rate, where Daily rate = Rent ÷ Days in that month, Rent × 12 ÷ 365, or Rent ÷ 30
```

Where:
- Days occupied: calendar days from the first to the last day, both included
- Daily rate: set by the method your lease uses

## Worked example
1. 15 to 30 November inclusive is 16 days; November has 30 days.
2. Daily rate = 1,500 ÷ 30 = 50.
3. Prorated rent = 16 × 50 = 800.

**Result:** Moving in on 15 November at 1,500 a month, the tenant owes 800 for November.

## What the result means

The three methods give slightly different answers in months that are not 30 days long. Follow the lease; if it is silent, actual days in the month is the most common practice.

## Assumptions and limits
- Both the first and last days are charged.
- Any month that is fully occupied is charged the full rent.
- Local law may set how rent is prorated or refunded; check it where you rent.

## Questions

### Why does February give a different daily rate?

With the actual-days method the monthly rent is spread over fewer days, so each day costs more. The 365-day and 30-day methods use the same daily rate all year.

### Can I prorate across several months?

Yes. Enter any start and end dates; full months are charged in full and only the partial months are prorated.
