1. What is Prorated Rent?

Prorated rent is a partial rent payment that covers only the days you actually occupy a rental unit during a month, rather than paying the full month's rent. This commonly occurs when you move in or out mid-month.

2. How Prorated Rent is Calculated

The standard formula for prorated rent is:

Where:

• Monthly Rent — The full monthly rental amount
• Days in Month — Total days in the month (typically 28-31)
• Days Occupied — Number of days you'll actually occupy the unit

Example: If your monthly rent is $1,200, you move in on the 15th of a 30-day month, you would pay for 16 days (including the move-in day): ($1,200 / 30) × 16 = $640.

3. California Prorated Rent Laws

Details: California law doesn't require landlords to prorate rent, but many do as a standard practice. The calculation method should be specified in your lease agreement. If not negotiated, the daily rate method shown here is most common.

4. Using the Calculator

Tips:

• Enter your full monthly rent amount
• Specify the number of days in the month (typically 28, 30, or 31)
• Enter the number of days you'll occupy the unit (including move-in/move-out day)
• The calculator will show your prorated rent amount

5. Frequently Asked Questions (FAQ)

Q1: Is prorated rent required by law in California?
A: No, California law doesn't require landlords to prorate rent, but many do as a courtesy. Check your lease agreement.

Q2: Should move-in day count as a full day?
A: Typically yes - if you take possession of the unit on that day, it counts as an occupied day.

Q3: What if my landlord uses a different calculation method?
A: Some landlords use a flat 30-day month for simplicity (even for February). The method should be specified in your lease.

Q4: Can I negotiate prorated rent?
A: Yes, prorated rent terms are negotiable before signing the lease. Get any agreements in writing.

Q5: What if I'm moving out mid-month?
A: The same calculation applies - you pay only for the days you occupy the unit that month.
