Prorated rent calculator

Calculate rent for a partial month at move-in or move-out.

The short answer

$2,000 rent, moving in on the 15th of a 30-day month, is $1,066.67 for that partial month.

Prorated rent

Prorated rent = daily rate × days occupied, where the daily rate depends on the convention you use

Show the arithmetic
  • Daily rate (actual): 66.67
  • Prorated rent: 66.67 × 16 days = 1066.67
Worked example

$2,000 rent, moving in on the 15th of a 30-day month, is $1,066.67 for that partial month.

Assumptions
  • Actual-days: monthly rent ÷ the actual number of days in that month. This is the most common and the most defensible.
  • 30-day (banker's) month: monthly rent ÷ 30, regardless of the real month length. Simpler, but it overcharges slightly in a 31-day month.
  • Annualized: (monthly rent × 12) ÷ 365 × days. Gives the same daily rate every month of the year.
  • Whether the move-in day itself is charged is a lease term, not a calculation — this counts it as occupied.

Every figure is calculated from the values you entered. Nothing is fetched from market data, and this is general information rather than financial, legal or tax advice.
