How Our Prorate Rent Calculator Works
Our prorate rent calculator determines fair partial month rent by dividing your monthly rent by the number of days in the month to establish a daily rate, then multiplying by the number of days occupied. The calculator supports multiple proration methods including actual calendar days and standard 30-day months, ensuring accurate calculations for move-in, move-out, and short-term rental scenarios.
Rent Proration Calculation Methods
The actual days method is more accurate and fair for both parties, as it accounts for months with different lengths (February vs. August). The 30-day method is simpler but may slightly favor the tenant in 31-day months and the landlord in 28/29-day months. Most professional property managers use the actual days method for accuracy.

Proration Best Practices
Proper rent proration requires clear communication and documentation between landlords and tenants. The proration method should be specified in the lease agreement to avoid disputes. Most landlords prorate based on actual calendar days in the specific month, which is considered the fairest method. Always calculate and document prorated amounts before move-in to ensure both parties understand the financial obligations.
- Actual days method: Most accurate, uses actual calendar days (28-31) for that month
- 30-day method: Simplified approach, always divides by 30 regardless of actual days
- Banker's method: Uses 360-day year (30-day months) for consistent calculations
- Move-in: Charge from move-in date through end of month, include move-in day
- Move-out: Charge from month start through move-out date, confirm if move-out day included
- Documentation: Always put prorated amounts in writing to avoid disputes
