Prorated rent calculator
Enter your monthly rent and the move-in or move-out date. You see the partial-month rent both ways.
Arithmetic only. The proration method comes from your lease.

This is general information based on the statute text, not legal advice. Your lease, local ordinances and court decisions can also matter. Nothing you type leaves your browser.
The two common methods
| Method | Daily rate | Example: $3,000, move in June 21 |
|---|---|---|
| Days in month | Rent ÷ days in that month | $3,000 ÷ 30 × 10 days = $1,000.00 |
| 365-day year | Rent × 12 ÷ 365 | $98.63 × 10 days = $986.30 |
Common questions
Q. Which method is correct, daily by month or by year?
A. Florida §83.49 and New York §7-108 do not set a proration method. Use the method in your lease; if it is silent, agree one with the landlord in writing. The calculator shows both so you can compare.
Q. Is the move-in or move-out day counted?
A. This calculator counts both: a move-in on the 21st pays for the 21st to the end of the month, and a move-out on the 10th pays for the 1st to the 10th. If your lease counts differently, adjust the date.
Q. Why is February so expensive per day?
A. With the by-month method the rent is divided by the days in that month, so a 28-day month gives a higher daily rate than a 31-day month. The by-year method uses the same daily rate all year.
