Prorated Rent Calculator
A tenant moving in mid-month should only pay for the days they actually live there. Enter the rent and move-in date to get the prorated amount — plus how it looks under each of the three standard methods.
We prorate from the move-in date through the last day of that month.
Pet fees, parking, storage, and other recurring monthly charges are prorated the same way as rent.
$3,250.00 ÷ 31 days = $104.84/day × 25 days = $2,620.97

Compare the three methods
Your lease should state which one you use. Select a method to update the totals above — when the lease is silent, the actual-days method is the standard.
How to prorate rent, step by step
Say the rent is $3,250/month and your tenant moves in on July 7. July has 31 days, and they occupy the unit from the 7th through the 31st — that's 25 days.
- 1. Find the daily rate
$3,250 ÷ 31 days = $104.84 per day
- 2. Count the days occupied
July 7 through July 31, inclusive = 25 days
- 3. Multiply
$104.84 × 25 days = $2,620.97 prorated rent
The three proration methods
Landlords use one of three conventions. The calculator above shows all three side by side so you can match whatever your lease says.
- Actual days in the month — divide by the real number of days (28–31). The most common and generally the fairest. This is our recommended default.
- 30-day (banker's) month — always divide by 30. Simpler, and specified by some leases and state guidelines.
- Actual days in the year — rent × 12 ÷ 365 for a flat daily rate that never changes month to month.
Frequently asked questions
How do you prorate rent for a mid-month move-in?
Find the daily rent (monthly rent ÷ days in the month), then multiply by the number of days the tenant occupies the unit — counting the move-in date through the last day of the month, inclusive.
Do you count the move-in day?
Yes. The move-in day is the tenant's first day of occupancy, so it's included in the billed days. A July 7 move-in is billed for July 7 through July 31 — 25 days.
Which proration method should I use?
Whatever your lease specifies. If the lease is silent, use the actual days in the month — it's the standard and it holds up best if a tenant ever disputes the charge. Be consistent across every tenant and every unit.
Is prorated rent legal to charge?
Yes. Proration simply charges a tenant for the portion of the month they actually occupy the unit. A few states and cities regulate the exact method, so check your local landlord-tenant rules if you're unsure.
