Prorate Rent Calculator: How to Calculate Prorated Rent for Any Move-In Date

Moving into a new rental property rarely happens on the first of the month. Whether you're a tenant wondering how much rent you actually owe or a landlord figuring out what to charge for a partial month, understanding rent proration is essential for a fair and transparent rental agreement.

Our free prorate rent calculator below makes it easy to determine the exact amount owed when moving in or moving out mid-month. Simply enter your monthly rent, select your move-in date, and get instant results showing your daily rent rate and total amount due.

What Is Prorated Rent?

Prorated rent (also called pro rata rent) is a partial month rent payment calculated based on the number of days a tenant actually occupies a rental property, rather than paying the full monthly amount. The rent proration formula divides your monthly rent into a daily rate and multiplies it by your actual days of occupancy—so you only pay for the time you're living there.

For example, if you move into an apartment on the 15th of a 30-day month with a $1,500 monthly rent, you'd pay approximately $750 for those 15 days of occupancy instead of the full $1,500.

When Is Prorated Rent Used?

Prorated rent typically applies in several common rental situations:

• Mid-month move-ins: When a tenant's lease starts on any day other than the first of the month
• Mid-month move-outs: When a tenant's lease ends before the last day of the month
• Early termination: When a tenant breaks their lease and moves out mid-month
• Lease renewals: When transitioning between lease terms that don't align with calendar months

How to Calculate Prorated Rent: The Formula

Figuring out how much rent you owe for a partial month is straightforward once you know the formula. Both methods convert your monthly rent to a daily rate, then multiply by your days of occupancy:

Method 1: Calculate Daily Rent by Calendar Days (Most Accurate)

This method calculates your daily rent rate based on the actual number of days in the specific month:

1. Find the daily rate: Divide monthly rent by the number of days in the month
2. Calculate days occupied: Count the days the tenant will live in the unit
3. Multiply: Daily rate x days occupied = prorated rent

Example: $1,500 monthly rent, moving in on March 20th

• Daily rate: $1,500 / 31 days = $48.39 per day
• Days occupied: March 20-31 = 12 days
• Prorated rent: $48.39 x 12 = $580.68

Method 2: Banker's Method (30-Day Standard)

Some landlords prefer consistency by using 30 days for every month, regardless of actual length:

1. Find the daily rate: Divide monthly rent by 30 (always)
2. Calculate days occupied: Count the days the tenant will live in the unit
3. Multiply: Daily rate x days occupied = prorated rent

Example: $1,500 monthly rent, moving in on March 20th

• Daily rate: $1,500 / 30 days = $50.00 per day
• Days occupied: 12 days
• Prorated rent: $50.00 x 12 = $600.00

Which Method Should You Use?

The daily rate method is more precise and is generally considered fairer, especially for months with 28 or 31 days. However, the banker's method offers simplicity and consistency, which some property managers prefer for standardized operations.

The most important thing is that both landlord and tenant agree on the calculation method before signing the lease.

Prorated Rent for Landlords: Best Practices

As a landlord or property manager, handling prorated rent correctly helps maintain positive tenant relationships and reduces disputes. Here are key practices to follow:

Include Proration Terms in Your Lease

Always specify in your lease agreement how prorated rent will be calculated. This should include:

• The calculation method you'll use (daily rate or banker's method)
• When prorated rent is due (at move-in, with first full month, etc.)
• How move-out proration will be handled

Document Everything

Provide tenants with a written breakdown showing:

• Monthly rent amount
• Daily rate calculation
• Move-in/move-out dates
• Number of days being charged
• Final prorated amount due

Consider Your Occupancy Strategy

Offering prorated rent can help you fill vacancies faster. A tenant who needs to move mid-month is more likely to choose your property if they don't have to pay for days they won't be occupying the unit.

Prorated Rent for Tenants: What You Need to Know

As a tenant, understanding prorated rent protects you from overpaying and helps you budget for move-in costs.

Verify the Calculation

Always ask your landlord for a breakdown of how they calculated your prorated rent. Use our calculator above to verify the amount is accurate before you pay.

Budget for Total Move-In Costs

Remember that prorated rent is just one part of your move-in expenses. You may also need to pay:

• Security deposit (typically one month's rent)
• First full month's rent (in addition to prorated amount)
• Application fees
• Pet deposits or fees
• Utility connection charges

Get It in Writing

Before signing your lease, ensure the prorated rent amount and due date are clearly documented. This protects both you and your landlord from future disputes.

Common Prorated Rent Scenarios

Still wondering how much rent you'll owe for your specific situation? Here are real-world examples showing how to calculate rent for a partial month in different scenarios:

Scenario 1: Moving In Mid-Month

Sarah signs a lease starting September 15th with a monthly rent of $1,800.

• Days in September: 30
• Daily rate: $1,800 / 30 = $60
• Days occupied (Sept 15-30): 16 days
• Prorated rent: $60 x 16 = $960

Sarah pays $960 for September plus $1,800 for October at move-in.

Scenario 2: Moving Out Early

Mike's lease ends on the 10th of November. His monthly rent is $1,400.

• Days in November: 30
• Daily rate: $1,400 / 30 = $46.67
• Days occupied (Nov 1-10): 10 days
• Prorated rent: $46.67 x 10 = $466.70

Scenario 3: February Proration

John moves into his apartment on February 20th in a non-leap year. His rent is $2,000.

• Days in February: 28
• Daily rate: $2,000 / 28 = $71.43
• Days occupied (Feb 20-28): 9 days
• Prorated rent: $71.43 x 9 = $642.87

Frequently Asked Questions About Rent Proration

Is prorated rent required by law?

No federal law requires landlords to offer prorated rent. However, many states have tenant protection laws that may address this issue. Most landlords offer proration as a standard practice because it's fair and helps attract tenants.

When is prorated rent typically due?

Prorated rent is usually due at move-in along with the security deposit and any other required fees. Some landlords may allow you to combine it with your first full month's rent payment.

Can I negotiate prorated rent?

Yes, prorated rent terms are typically negotiable before signing a lease. You can discuss the calculation method and payment timing with your landlord. However, the amount itself is determined by the formula, so there's limited room for negotiation there.

What if my landlord refuses to prorate rent?

While not legally required in most areas, refusing to prorate rent is uncommon. If a landlord insists on full monthly payment regardless of move-in date, you may want to consider other rental options or negotiate a later move-in date that aligns with the beginning of a month.

Does prorated rent apply to utilities?

Prorated rent calculations typically only apply to the base rent. Utilities are usually billed separately based on actual usage, which is already prorated by the utility company based on meter readings or billing cycles.

How do I convert monthly rent to daily rent?

To calculate your daily rent rate, simply divide your monthly rent by the number of days in the month. For example, if your rent is $1,500 and the month has 30 days, your daily rate is $50 ($1,500 ÷ 30 = $50). Some landlords use a standard 30-day calculation regardless of the actual month length for consistency.

What is the difference between prorated rent and partial month rent?

Prorated rent and partial month rent mean the same thing—both refer to paying only for the days you occupy a rental property rather than the full monthly amount. Rent proration is the formal term landlords and property managers use, while partial month rent is a more casual way tenants often describe it.
