The basics
What is prorated rent?
Prorated rent is the slice of a month's rent you owe when you move in or out partway through it. Instead of paying for days you don't live there, you pay a daily rate for only the days you do. It rests on two numbers: a per-day price, and a count of billable days.
daily rate = rent ÷ days
The daily rate
Take the full monthly rent and divide by the number of days the method uses as its base. That gives the price of a single day in the unit.
$1,500 ÷ 30 = $50.00 / day
prorated = daily rate × days
The billable days
Count the days you actually occupy the unit — move-in day through the end of the month — and multiply by the daily rate. That partial total is your prorated rent.
$50.00 × 16 days = $800
Method
How to prorate rent by hand
Three steps, whichever direction you're moving.
- 1
Find the daily rate
Divide the monthly rent by the number of days your lease prorates against — usually the actual days in that month.
$1,500 ÷ 30 days = $50.00 / day - 2
Count the billable days
For a move-in, count from your move-in date through the last day of the month, inclusive. For a move-out, count from the 1st through your move-out day.
June 15 → June 30 = 16 days - 3
Multiply
Multiply the daily rate by the billable days. That product is the rent you owe for the partial month.
$50.00 × 16 = $800.00

Where it shows up
When you'll need this
Proration turns up at both ends of a tenancy and in the in-between cases landlords handle every month.
move-in day → month end
Mid-month move-in
The classic case: you sign a lease that starts on the 15th and owe only the back half of that first month before full rent begins.
month start → move-out day
Mid-month move-out
You give notice and leave before month's end, so the final month is billed only for the days you stayed.

Worth knowing
Rules and edge cases
A handful of conventions decide whether the number on your first invoice is fair.
count both endpoints
The move-in day is billed
Standard practice charges the day you take possession, so a move-in counts from that date through month end inclusive. Confirm it, since a single day shifts the total.
29 days in a leap February
Leap years matter
February's denominator is 28 most years and 29 in a leap year. Using the wrong one over- or under-charges by a day's rent.
rent ÷ 30 vs rent ÷ days
The 30-day shortcut
Dividing by a flat 30 is simpler but slightly mis-prices every month except those with 30 days. It favors the landlord in February and the tenant in 31-day months.
get it in writing
The method is the lease's
No single method is universally required. Whichever your lease names governs — so read the clause and keep the calculation on record.
move-in + move-out = 1 month
Mirror images
Move-in proration (day → end) and move-out proration (start → day) are complements: a tenant moving in on the same day another moves out together pay close to one full month.
round to the cent
Rounding
Daily rates rarely land on a clean cent. Most leases round the final prorated total to the nearest cent rather than rounding the daily rate first.
Reference
The proration denominators
The only thing that changes between methods is what you divide the monthly rent by.
MethodDaily rate of $1,500/mo
Actual days · February (28)$1,500 ÷ 28 = $53.57
Actual days · April (30)$1,500 ÷ 30 = $50.00
Actual days · July (31)$1,500 ÷ 31 = $48.39
Flat 30-day month$1,500 ÷ 30 = $50.00
Annualized · 365-day$1,500 × 12 ÷ 365 = $49.32

Common mistakes
Where the first invoice goes wrong
A prorated total is small money, but these four slips are the ones that spark a dispute.
both endpoints count
Off by one day
Forgetting that the move-in day itself is billed drops a day. June 15 to June 30 is 16 days, not 15 — count both ends.
÷ actual days
Always dividing by 30
A flat 30-day divisor over- or under-charges every month that isn't 30 days. February and the 31-day months need their own denominator unless the lease says otherwise.
round the total, not the rate
Rounding too early
Rounding the daily rate first and then multiplying compounds the error. Keep the full rate and round only the final total to the cent.
prorated ≠ deposit
Mixing in other charges
Prorated rent covers only the partial month. Bundling it with the security deposit or a full month's rent hides what you actually owe for the days you live there.
FAQ
Common questions
Divide the monthly rent by the number of days in the month to get a daily rate, then multiply that daily rate by the number of days you actually occupy the unit. For $1,500 rent moving in on June 15, the daily rate is $1,500 ÷ 30 = $50, and 16 billable days (the 15th through the 30th) gives $50 × 16 = $800.
Yes. The standard convention bills the move-in day itself, so you count from the move-in date through the last day of the month inclusive. Moving in on the 15th of a 30-day month means 16 billable days, not 15, because both the 15th and the 30th are charged.
It depends on the lease. The most common and tenant-fair method divides by the actual days in that month (28, 29, 30, or 31). Some landlords use a flat 30-day month or an annualized 365-day rate. The methods give slightly different daily rates, so this calculator shows all three and the spread between them.
Because the calendar does. Under the actual-days method, $1,500 a month is $48.39/day in a 31-day July but $53.57/day in a 28-day February. Dividing by the real number of days keeps the monthly total exactly $1,500 no matter the month.
Charge from the 1st of the month through your move-out day, inclusive. Switch the calculator to “Moving out” mode: if you leave on the 10th, you pay for 10 days. Move-in and move-out proration are mirror images that together cover one full month.
No. Prorated rent only covers the partial first (or last) month you occupy the unit. It is separate from the security deposit and from any full months of rent. Many leases collect the prorated amount up front alongside the deposit.
Proration is a matter of the lease and local norms rather than a universal legal requirement, so terms vary. Most leases prorate a mid-month move-in, but always confirm the method in writing — the difference between dividing by 30 and by the actual days is real money over the life of a lease.
Use 29 days as the denominator. In a leap year, $1,500 ÷ 29 = $51.72/day under the actual-days method. The calculator detects leap years automatically when you pick February of a leap year, so the daily rate is always correct.
