Not every lease starts on the 1st or ends on the 30th. Sometimes tenants move in on the 10th, or a lease ends on the 20th. In such cases, landlords can’t fairly charge the full monthly rent — instead, the rent is prorated.
A Prorated Lease Calculator makes it easy to calculate exactly how much rent is owed when the lease term doesn’t align with the full rental period.
This tool is widely used by:
- Landlords & Property Managers – for fairness and accuracy.
- Tenants – to check charges on move-in or move-out.
- Businesses – for prorating office, equipment, or vehicle leases.
What is a Prorated Lease?
A prorated lease means charging rent only for the days occupied rather than the full month.
Example:
- Monthly rent = $1,200
- Tenant moves in on the 10th of a 30-day month
- Prorated rent = $1,200 ÷ 30 × 21 = $840
This ensures fairness to both landlord and tenant.

Practical Examples
Example 1: Apartment Lease
- Rent: $1,200
- Month: 30 days
- Move in: 10th → Occupied = 21 days
- Prorated Rent = $1,200 ÷ 30 × 21 = $840
Example 2: 31-Day Month
- Rent: $1,550
- Month: 31 days
- Move out: 20th → Occupied = 20 days
- Prorated Rent = $1,550 ÷ 31 × 20 = $1,000
Example 3: Office Lease
- Rent: $3,000/month
- Tenant moves in on the 15th (30-day month).
- Occupied = 16 days
- Rent = $3,000 ÷ 30 × 16 = $1,600
Example 4: Equipment Lease
- Equipment Rent = $2,400/month
- Returned 10 days early in a 30-day month.
- Credit = $2,400 ÷ 30 × 10 = $800 refund
