The answer at a glance
Prorated rent = (monthly rent ÷ 28) × 4. A 28-day month gives a daily rate of rent ÷ 28, and a move-in on day 25 leaves 4 billable days. That is $ $35.71 per day on $1,000 rent, and $142.86 due for the partial month.
The table below pre-calculates that arithmetic for rents from $1,000 to $3,000 so you can read your number off directly.
| Monthly Rent | Daily Rate (28 days) | Days Owed | Prorated Rent |
|---|---|---|---|
| $1,000 | $35.71 | 4 of 28 days | $142.86 |
| $1,500 | $53.57 | 4 of 28 days | $214.29 |
| $2,000 | $71.43 | 4 of 28 days | $285.71 |
| $2,500 | $89.29 | 4 of 28 days | $357.14 |
| $3,000 | $107.14 | 4 of 28 days | $428.57 |
Figures use the actual-days-in-the-month basis. A flat 30-day basis or a 365-day year gives a slightly different answer — the interactive calculator shows all three side by side.
How this is calculated
Rent is billed per day, and a move-in on day 25 means possession for 4 days of the 28. Two conventions decide the daily rate: the actual days in the month, or a flat 30-day month. This page uses the actual month, which is the most common lease default.
Prorated rent = (monthly rent ÷ 28) × (28 − 25 + 1)
= (monthly rent ÷ 28) × 4
The 30-day and 365-day bases exist because some leases quote a flat month. At 28 days the calendar basis is close to, but not the same as, a 30-day basis except in a 30-day month; check your lease for which one applies before you pay.

Frequently asked questions
4 answers, no funnel.
How much rent do I owe if I move in on day 25 of a 28-day month?
You owe 4 of the month's 28 days, which is 14.3% of a full month. Divide the monthly rent by 28 to get the daily rate, then multiply by 4. On $1,800 rent that is $64.29 a day and $257.14 due.
What is the daily rent rate in a 28-day month?
The daily rate is the monthly rent divided by 28. On $1,500 rent it is $53.57 per day. A landlord using a flat 30-day basis instead would divide by 30, and one using the 365-day year would divide by 365 and multiply by 12.
Is a move-in on day 25 charged from that day or the whole month?
You are charged from the move-in day through the end of the month, both days inclusive, so 4 days here. The rest of the month, before you took possession, is not billed as regular rent.
How is prorated rent different from a full month?
A full month bills all 28 days. Moving in on day 25 bills only 4, so you pay 14.3% of a full month and save the other 85.7%.
