The answer at a glance
Prorated rent = (monthly rent ÷ 31) × 6. A 31-day month gives a daily rate of rent ÷ 31, and a move-in on day 26 leaves 6 billable days. That is $ $32.26 per day on $1,000 rent, and $193.55 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 (31 days) | Days Owed | Prorated Rent |
|---|---|---|---|
| $1,000 | $32.26 | 6 of 31 days | $193.55 |
| $1,500 | $48.39 | 6 of 31 days | $290.32 |
| $2,000 | $64.52 | 6 of 31 days | $387.10 |
| $2,500 | $80.65 | 6 of 31 days | $483.87 |
| $3,000 | $96.77 | 6 of 31 days | $580.65 |
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 26 means possession for 6 days of the 31. 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 ÷ 31) × (31 − 26 + 1)
= (monthly rent ÷ 31) × 6
The 30-day and 365-day bases exist because some leases quote a flat month. At 31 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 26 of a 31-day month?
You owe 6 of the month's 31 days, which is 19.4% of a full month. Divide the monthly rent by 31 to get the daily rate, then multiply by 6. On $1,800 rent that is $58.06 a day and $348.39 due.
What is the daily rent rate in a 31-day month?
The daily rate is the monthly rent divided by 31. On $1,500 rent it is $48.39 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 26 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 6 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 31 days. Moving in on day 26 bills only 6, so you pay 19.4% of a full month and save the other 80.6%.
