Prorated Rent Calculator
Calculate prorated rent for any move-in / move-out period. Choose between actual days-per-month proration or a 30-day standard. Results update instantly.
Notes:
• The actual days method computes each day’s share using the number of days in that specific month (e.g., Feb=28/29).
• The 30-day method uses a fixed daily rate = monthly ÷ 30 (common in some leases).
• Always confirm the lease or landlord’s stated proration method; local laws may affect calculations.
What is Prorated Rent?
Prorated rent is the portion of a full month’s rent a tenant pays when moving in or out on a day other than the first or last day of the month. Instead of paying the entire month, the tenant pays only for the days they occupy the unit. A Prorated Rent Calculator makes this quick and error-free.
Why Use a Prorated Rent Calculator?
Manual prorating is easy to get wrong — especially when months have different lengths or when leases start mid-month. This calculator removes confusion and gives landlords and tenants a transparent, accurate amount to pay. It’s ideal for move-ins, move-outs, lease changes, and partial-month billing.
How Prorated Rent Is Calculated (Simple Formula)
The most common method is daily proration:
- Find the monthly rent.
- Determine the number of days in the month (28–31).
- Divide monthly rent by the number of days to get a daily rate.
- Multiply the daily rate by the number of days the tenant occupies the unit.
Formula:Prorated rent = (Monthly rent ÷ Days in month) × Number of days occupied
Example: For $1,200 monthly rent, moving in on the 11th of a 30-day month:
Daily rate = $1,200 ÷ 30 = $40
Days occupied = 20 → Prorated rent = 40 × 20 = $800
Common Variations & Tips
- Some landlords use a 30-day standard for every month (flat daily rate = monthly ÷ 30). This simplifies accounting but slightly favors one party depending on the month.
- Always clarify which method your lease uses (actual days vs. 30-day month). Put the rule in writing to avoid disputes.
- For lease terminations, ensure move-out and pro-rating align with local laws — some jurisdictions have specific rules.
Final Note
A Prorated Rent Calculator keeps move-ins and move-outs fair and simple. Whether you’re a landlord, property manager, or tenant, this tool removes guesswork and speeds up billing. For legal questions or complex lease clauses, consult a property professional or local housing authority.
