Prorated Rent Moving Out Calculator
Prorated rent is calculated by dividing your monthly rent by the number of days in the month, then multiplying by the number of days you occupy the unit. For example, if your rent is $1,800/month and you move out on March 15 (a 31-day month), you owe $1,800 ÷ 31 × 15 = $870.97.
Prorated Rent = (Monthly Rent ÷ Days in Month) × Days Occupied
When you move out mid-month, you shouldn't pay for days you don't occupy the apartment. Our prorated rent calculator determines exactly what you owe for a partial month, helping you avoid overpaying your landlord. The calculation is straightforward but varies slightly depending on whether your lease uses calendar days or a standard 30-day month.
Most leases require written notice (typically 30–60 days) before moving out. Check your lease agreement and local tenant laws at your state's HUD office to understand your specific rights regarding prorated rent when vacating.
What This Means
Your prorated rent amount is what you owe for the partial month based on the days you occupied the unit. Keep documentation of your move-out date — a dated and signed notice to vacate, forwarded mail confirmation, and photos of the empty unit with timestamps. If your landlord charges a full month's rent instead of prorated, you may be entitled to a refund depending on your lease terms and state law.
How to Calculate Prorated Rent
There are two common methods for calculating prorated rent. Check your lease to see which one applies:
Method 1: Calendar Days (Most Common)
Divide monthly rent by the actual number of days in the move-out month, then multiply by the number of days you occupied the unit.
Formula: Prorated Rent = (Monthly Rent ÷ Days in Move-Out Month) × Days Occupied
Method 2: Standard 30-Day Month
Some leases use a standard 30-day month regardless of the actual calendar month. This simplifies the calculation but can slightly overcharge or undercharge depending on the month.
Formula: Prorated Rent = (Monthly Rent ÷ 30) × Days Occupied
Quick Reference: Daily Rent Rate by Monthly Rent
| Monthly Rent | Daily Rate (30-day) | Daily Rate (31-day) | Daily Rate (28-day Feb) |
|---|---|---|---|
| $1,000 | $33.33 | $32.26 | $35.71 |
| $1,500 | $50.00 | $48.39 | $53.57 |
| $2,000 | $66.67 | $64.52 | $71.43 |
| $2,500 | $83.33 | $80.65 | $89.29 |
| $3,000 | $100.00 | $96.77 | $107.14 |
Worked Examples
Example 1: Moving Out Mid-March
Rent: $1,800/month. Move-out date: March 15. March has 31 days.
| Step | Calculation | Result |
|---|---|---|
| Daily rate | $1,800 ÷ 31 | $58.06 |
| Days occupied (March 1–15) | 15 days | — |
| Prorated rent | $58.06 × 15 | $870.97 |
| Savings vs. full month | $1,800 – $870.97 | $929.03 |
Example 2: Moving Out Late Month
Rent: $2,200/month. Move-out date: April 25. April has 30 days.
| Step | Calculation | Result |
|---|---|---|
| Daily rate | $2,200 ÷ 30 | $73.33 |
| Days occupied (April 1–25) | 25 days | — |
| Prorated rent | $73.33 × 25 | $1,833.33 |
| Savings vs. full month | $2,200 – $1,833.33 | $366.67 |
Prorated Rent When Moving In
Proration also applies when you move into a new apartment mid-month. Your first month's payment should be prorated from your move-in date through the end of the month, plus the next full month's rent.
Example: Moving into a $1,600/month apartment on March 20. March has 31 days.
- Days remaining in March: 12 (March 20–31)
- Daily rate: $1,600 ÷ 31 = $51.61
- Prorated March rent: $51.61 × 12 = $619.35
- Amount due at move-in: $619.35 (prorated March) + $1,600 (April rent) + security deposit
This means you can coordinate your move-out proration at the old place with move-in proration at the new place to minimize overlap costs. Ideally, your last day at the old apartment is the day before your first day at the new one.
Your Rights Regarding Prorated Rent
Prorated rent policies vary by state and lease terms:
- Lease terms control. If your lease specifies a proration method, that method applies. If the lease is silent, most courts apply the calendar-day method.
- Month-to-month tenancy. If you're on a month-to-month lease and give proper notice (usually 30 days), you're entitled to prorated rent for the partial month. For example, giving notice on March 5 means you pay through April 5 and owe prorated April rent only.
- Fixed-term lease. If your fixed-term lease ends mid-month, you pay only through the lease end date. If you break the lease early, proration depends on state law and lease terms — some states require landlords to prorate while others allow them to charge a full month.
- Security deposit timing. Under most state laws, landlords must return your security deposit within 14–30 days of move-out. Any prorated rent overpayment should be applied to your final accounting.
For state-specific tenant rights, consult your local HUD office or tenant rights organization.

Frequently Asked Questions
Do I have to pay a full month's rent if I move out mid-month?
In most cases, no. If you give proper notice (typically 30 days for month-to-month leases), you should only pay rent through your move-out date. However, your lease may have specific terms. Some leases require rent through the end of the notice period rather than the move-out date. For example, if you give 30-day notice on March 10, you may owe rent through April 10, even if you move out March 25. Always check your lease and state law.
How do I calculate prorated rent for moving in?
Divide the monthly rent by the number of days in the move-in month, then multiply by the number of days remaining (including move-in day). For example, moving in on the 20th of a 30-day month with $1,500 rent: $1,500 ÷ 30 × 11 = $550 for the partial month. You'll typically pay this prorated amount plus the next full month's rent and security deposit at move-in.
Can a landlord refuse to prorate rent?
It depends on the situation. If your lease ends mid-month (fixed-term lease expiration), the landlord must prorate — you can't be charged for days after the lease ends. For early termination or month-to-month with proper notice, most states require proration but some lease clauses may override this. If you break a lease without cause, the landlord may not be required to prorate and could charge penalties. Always review your lease and consult a local tenant rights organization if there's a dispute.
Is it better to move at the beginning or end of the month?
Moving at the beginning of the month (1st–5th) is generally better because: (1) you minimize overlap between old and new rent, (2) most leases align with calendar months, and (3) you avoid paying for days you're not living in either place. Moving at the end of the month means you pay nearly full rent at the old place and must coordinate move-in proration at the new place. Mid-month moves offer the most flexibility but create the highest chance of double-paying rent during the overlap period.
