How It Works

Moving in or out partway through a month leaves you owing rent for only part of it, and proration is how that partial amount gets settled fairly so neither tenant nor landlord overpays or comes up short. Move into an apartment on August 15, 2026, for instance, and charging you for the whole month would not be right.

Start by working out the daily rent: take the full monthly rent and divide it by the actual number of days in that particular month, which means 31 days for August 2026, 30 days for September 2026, or 28 days for February 2026, since 2026 is not a leap year. Multiply that daily figure by the number of days you will actually occupy the place during the partial month, and you have the amount owed.

Pin down the exact move-in or move-out date against your lease before running the numbers, because a mismatch there throws everything off. Some leases also define a month as a flat 30 days no matter the calendar, so read your agreement carefully. The error that trips people up most is dividing by 30 every time, which produces the wrong daily rate for any month with 28, 29, or 31 days.

Example: Moving into a new apartment in August 2026

  1. 1 Full monthly rent: $1,500. Move-in date: August 18, 2026.
  2. 2 August 2026 has 31 days. Daily rent = $1,500 / 31 = $48.39 (rounded). Number of days occupied in August = 14 days (August 18th to 31st inclusive). Prorated rent = $48.39 * 14 = $677.46.
  3. 3 The prorated rent for August 2026 is $677.46.
  4. 4 This means the tenant would pay $677.46 for their first month, covering only the days they actually resided in the apartment. This is significantly less than the full $1,500 monthly rent, demonstrating the financial benefit of accurate prorated rent calculations.

Frequently Asked Questions

How do you calculate prorated rent?
Divide monthly rent by the number of days in the month, then multiply by the number of days you occupy the unit. Moving in on the 15th of a 30-day month at $1,500/month: ($1,500/30) x 16 = $800.
Do you prorate rent by calendar days or 30 days?
Most landlords prorate by the actual number of days in the move-in month. Some use a standard 30-day month. Check your lease for the specific method. The difference is usually small.
Do I pay prorated rent when I move out?
If you move out mid-month, you should only pay rent for the days you occupy the unit, assuming proper notice was given per your lease terms. Your landlord should prorate the final month's rent accordingly.
