Prorated rent calculator for move-in and move-out
Leases rarely start on the 1st. This prorated rent calculator works out the rent for the part of a month you actually occupy — the first month when you move in mid-month, the last month when you move out, or any custom run of dates across several months. Enter the monthly rent and the date, pick the method your lease uses, and you get the amount, the daily rate and the number of days charged.
Because landlords and property managers use different methods, the table underneath shows the same dates priced three ways: by the actual number of days in that month, by a 30-day “banker’s” month, and by a yearly daily rate (rent × 12 ÷ 365). Seeing all three side by side settles most disputes quickly. It works in dollars, pounds, euros, rupees, dirhams and more, runs in your browser, and is free. It is a calculation aid, not legal advice: what you owe is set by your lease and local law.
How to use the Prorated Rent Calculator
- Choose Move-in month, Move-out month or Custom dates.
- Enter the Monthly rent and pick the currency.
- Pick the Move-in date or Move-out date (for custom dates, the first and last day charged).
- Choose the Daily rate method your lease names, and whether the move-in or move-out day itself is charged.
- Read the prorated rent, then compare the three methods in the table.
Prorated Rent Calculator features
Three proration methods
Actual days in the month, a 30-day month and a 365-day year — the three methods leases and property-management software use most.
Move-in, move-out or any range
Custom dates can cross several months; each month is priced on its own days and whole months are charged at the full rent.
Day-count control
Decide whether the move-in or move-out day is charged; the default counts it, which is the usual practice.
Any currency
USD, GBP, EUR, INR, AUD, CAD and AED with the right symbol and two decimals.
How to calculate prorated rent
Prorated rent is the daily rate × the number of days occupied. The methods differ only in how the daily rate is found:
| Method | Daily rate | $1,500 rent, 13 days in November |
|---|---|---|
| Actual days in that month | Rent ÷ days in the month (28–31) | $1,500 ÷ 30 × 13 = $650.00 |
| 30-day (banker’s) month | Rent ÷ 30, every month | $1,500 ÷ 30 × 13 = $650.00 |
| Yearly, 365 days | Rent × 12 ÷ 365 | $49.32 × 13 = $641.10 |
Which method is fair?
The actual-days method charges exactly the share of the month you used, so 15 days of a 30-day month is half the rent, but a day in February costs more than a day in July. The 30-day method uses one daily rate all year; it slightly favours the landlord in 31-day months and the tenant in February, so this calculator caps any partial month at one month’s rent. The yearly method gives the same daily rate every day of the year, which suits long or multi-month periods and is what many accounting systems use. Some years have 366 days; this tool keeps 365, the common convention.
Whichever method you use, agree it in writing. If the lease is silent, the actual-days method is the easiest to explain and is the default here. When you move out, check the notice period too — some leases require rent for the whole notice period or a full final month whatever the move date.
Tips for landlords and tenants
- Put the proration method and the first payment amount in the lease or move-in letter, and issue a receipt for the partial month with the rent receipt generator.
- Some landlords collect the prorated amount together with the first full month; others collect it on move-in day. Either is fine if both sides know.
- To count days between any two dates yourself, use the date difference calculator.
- Drafting a new tenancy? The rent agreement generator lets you write the rent date and proration rule into the agreement.
Prorated Rent Calculator FAQ
How do I calculate prorated rent for a move-out?
Divide the monthly rent by the number of days in the month (or by 30, or use rent × 12 ÷ 365) and multiply by the days from the 1st up to and including your move-out date. The prorated rent calculator does this for all three methods at once.
How is prorated rent calculated for move-in?
Count the days from the move-in date to the end of that month, including the move-in day, and multiply by the daily rate. Moving in on 18 November means 13 days of a 30-day month.
Is there a prorated rent law in Texas?
This tool cannot give legal advice. In Texas, as in most places, the method is normally set by the lease, so read your lease first and ask a local tenant-rights organisation or lawyer if it is unclear.
Does a landlord have to prorate rent?
That depends on the lease and local law. Many leases prorate the first month automatically; for move-out, some require a full month or the full notice period instead.
Is the move-in day counted?
Usually yes — you have the keys that day. Untick “Charge the move-in day itself” if your agreement says the tenancy starts the next day.
Is this prorated rent calculator free?
Yes. It is free, needs no sign-up, and everything is calculated in your browser.
