When moving into or out of a rental property mid-month, calculating how much rent should be paid can become confusing. This is where a Prorent Calculator comes in handy. It helps both tenants and landlords determine the exact amount of rent owed based on the number of days a tenant occupies the property.
Whether you are starting a lease in the middle of the month, ending early, or dealing with lease renewals, prorating ensures fairness for both sides. In this guide, we’ll explain what prorated rent is, how to use the calculator, formulas used, step-by-step examples, and answer common questions.

What is Prorated Rent?
Prorated rent is the portion of the monthly rent that a tenant pays when they live in a rental property for only part of the month.
For example, if your monthly rent is $900, and you move in on the 15th day of a 30-day month, you only owe for 16 days instead of the full month.
Formula for Prorated Rent
The prorated rent depends on whether the landlord uses a monthly, yearly, or daily method. The most common approach is based on daily rent.
Daily Rent Formula:
Daily Rent = Monthly Rent ÷ Number of Days in Month
Prorated Rent Formula:
Prorated Rent = Daily Rent × Number of Days Tenant Occupied
This ensures the rent amount matches the exact number of days the property was occupied.
How to Use the Prorent Calculator
Using the Prorent Calculator is simple and user-friendly. Here’s how:
- Enter Monthly Rent – Input the standard full rent for the property.
- Enter Lease Start/End Date – Add the exact day you move in or move out.
- Enter Total Days in Month – Usually 28, 30, or 31 depending on the month.
- Click Calculate – The calculator will instantly provide your prorated rent.
This makes it quick and eliminates manual calculations.
Example Calculations
Example 1: Tenant Moving in Mid-Month
- Monthly Rent = $1,200
- Month = April (30 days)
- Move-in Date = 10th April
Step 1: Daily Rent = $1,200 ÷ 30 = $40/day
Step 2: Days Occupied = 21 days (10th–30th)
Step 3: Prorated Rent = $40 × 21 = $840
Example 2: Tenant Leaving Early
- Monthly Rent = $900
- Month = June (30 days)
- Move-out Date = 20th June
Step 1: Daily Rent = $900 ÷ 30 = $30/day
Step 2: Days Occupied = 20 days (1st–20th)
Step 3: Prorated Rent = $30 × 20 = $600
Example 3: February Lease Start
- Monthly Rent = $1,000
- Month = February (28 days)
- Move-in Date = 15th February
Step 1: Daily Rent = $1,000 ÷ 28 = $35.71/day
Step 2: Days Occupied = 14 days (15th–28th)
Step 3: Prorated Rent = $35.71 × 14 = $500
