Use Cases

Moving in mid-month

When you move into a rental unit partway through the month, you only owe rent for the days you occupy. This calculator helps you determine the exact amount to pay.

Example: Rent $1,200, move in on the 15th of a 30-day month, occupied days = 16, prorated rent = $640.

Moving out before the end of the month

If you move out before the lease ends, you may only be responsible for rent up to your move-out date. This tool calculates the prorated amount for the days you used.

Example: Rent $1,500, move out on the 10th of a 31-day month, occupied days = 10, prorated rent = $483.87.

Frequently Asked Questions

How is prorated rent calculated?
Prorated rent is calculated by dividing the full-period rent by the total days in the period to get a daily rate, then multiplying that daily rate by the number of occupied days. For example, if rent is $1,000 for 30 days and you occupy 10 days, you owe $333.33.
What does 'days in period' mean?
Days in period is the total number of days in the billing period, such as 30 or 31 for a month, or 365 for a year. It is used to determine the daily rent rate.
Can I use this for any partial period?
Yes, you can use this calculator for any partial period, such as moving in mid-month, moving out early, or subletting for a few days. Just enter the full rent, the number of days you occupy, and the total days in that period.

Tips & Common Mistakes

Tips

  • Double-check the number of occupied days: include both move-in and move-out days if you occupy them, or follow your lease agreement's policy.
  • Use the exact number of days in the period (e.g., 30, 31, 28, or 365) to get the most accurate daily rate.
  • If your lease specifies a different proration method (e.g., based on 30 days regardless of month length), adjust the 'days in period' accordingly.
  • Round the result to two decimal places for payment, but confirm with your landlord if they expect rounding up or down.

Common Mistakes to Avoid

  • Using the number of days in a month as 30 when the month has 31 days, leading to an inaccurate daily rate.
  • Forgetting to include the move-in day or move-out day in the occupied days count, which can under- or over-estimate the rent owed.
  • Entering the full-period rent as the monthly rent but using a period longer than one month (e.g., 365 days) without adjusting the rent amount.
