How Our Rent Prorate Calculator Works

Our rent prorate calculator calculates prorated rent for partial months using daily proration methods. The calculation applies daily proration formulas to determine accurate rent amounts for move-in, move-out, and partial month occupancy.

Daily Proration Formula

Prorated Rent = (Monthly Rent ÷ Days in Month) × Prorated Days

Where daily rate is calculated by dividing monthly rent by total days in month

Understanding Rent Proration Methods

Rent proration ensures fair payment for partial month occupancy. Different methods include daily proration (most accurate), banker's method (30 days for all months), and calendar method (actual calendar days). Daily proration is most common and provides the most accurate calculation.

  • Daily Proration: Most accurate, uses actual days in month
  • Banker's Method: Uses 30 days for all months, simpler calculation
  • Calendar Method: Uses actual calendar days, similar to daily
  • Move-In Proration: From move-in date to end of month
  • Move-Out Proration: From start of month to move-out date
  • Partial Month: Between specific start and end dates

Rent Prorate Calculator Examples

Rent Prorate Calculator Example
Calculate prorated rent for $1,500 monthly rent with move-in on January 15th

Rental Parameters:

  • Monthly Rent: $1,500
  • Move-In Date: January 15th
  • Days in Month: 31 days
  • Proration Method: Daily
  • Security Deposit: $1,500
  • Application Fee: $50

Calculation Steps:

  1. Daily Rent = $1,500 ÷ 31 = $48.39
  2. Prorated Days = 17 days (Jan 15-31)
  3. Prorated Rent = $48.39 × 17 = $822.58
  4. Total Move-In = $822.58 + $1,500 + $50 = $2,372.58
  5. Proration % = (17 ÷ 31) × 100 = 54.84%
  6. Savings = $1,500 - $822.58 = $677.42

Result: Daily Rent = $48.39, Prorated Rent = $822.58, Total Move-In = $2,372.58

This proration saves $677.42 compared to full month rent.
