The math
How it’s calculated
Your numbers, step by step. The total is rounded once, to the cent, so it can differ by a few cents from the rounded daily rate times the days.
- Daily rate $1,500 ÷ 31 days in October = $48.3871 a day
- Days charged October 12, 2026 to October 31, 2026, both days counted = 20 days
- You owe $1,500 × 20 ÷ 31 = $967.74
Three methods
Your landlord may use a different method
On these dates the three methods are up to $32.26 apart.
| Method | Daily rate | Days | You owe |
|---|---|---|---|
| Actual days Selected | $48.39 | 20 | $967.74 |
| 30-day month Selected | $50.00 | 20 | $1,000.00 |
| 365-day year Selected | $49.32 | 20 | $986.30 |
Whatever the method, a whole month is one month’s rent: moving in on the 1st or out on the last day means there is nothing to prorate.
FAQ
Questions people ask
What is prorated rent?
Prorated rent is rent for part of a month. When a lease starts or ends mid-month, you pay a daily rate for the days the place is yours instead of the full month.
Moving in October 12 on $1,500 rent, that is $967.74 for 20 days, using the actual days in October.
Which method do landlords use?
Most divide the rent by the actual number of days in that month: 28, 29, 30 or 31. Some use a flat 30-day month, which charges a little more per day in 31-day months and a little less in February. Others annualize: rent × 12 ÷ 365.
The difference is usually small but real. On the October 12 example, a 30-day month comes to $1,000.00 instead of $967.74. If your lease names a method, that one applies; if it doesn’t, ask before you pay. The table above shows all three for your dates.
Does my landlord have to prorate rent?
Generally, no. Most states have no statute that requires a landlord to prorate rent; the lease governs. A landlord can ask for a full month for a mid-month start, or prorate it, as long as the lease says so.
If you are moving in mid-month, ask for proration in writing before you sign. Many landlords agree because it is common practice. This is general information, not legal advice for your state.
How does prorated rent work when moving out?
Same math at the other end of the month: you pay from the 1st through your move-out day. Moving out October 12 on $1,500 rent is $580.65 for 12 days by actual days.
Many leases ask for a full month’s notice and rent through the end of the notice period, so a mid-month move-out is prorated only when the lease or the landlord allows it. Switch the calculator to Moving out to see your number.
Do I pay prorated rent in the first month or the second?
Usually the first: you pay the partial month when you move in, then full rent on the 1st.
When you move in late in the month, some landlords collect the partial month together with the next full month, so you are not asked for rent again a few days later. Both are common. Your lease or move-in statement should say which, and it is fair to ask.
