Moving in (or out) mid-month? Enter the monthly rent, the move-in date, and the day rent is normally billed, the calculator instantly shows the partial rent due, the daily rate, and exactly which days are being charged. Free, instant, and no email required.
Prorated rent is a partial month's rent, charged when a tenant occupies a unit for only part of a billing cycle, most commonly a mid-month move-in. Instead of paying a full month, the tenant pays a daily rate (monthly rent ÷ days in that month) for each day from the move-in date through the day before the next regular billing date.
Daily rate = monthly rent ÷ days in that calendar month. Prorated rent = daily rate × billable days. Example: rent is $1,500, the tenant moves in July 15, and rent is billed on the 1st. July has 31 days, so the daily rate is $1,500 ÷ 31 = $48.39. The tenant owes July 15 to 31 = 17 days × $48.39 = $822.58, and the first full month is billed August 1.
Many leases bill on the anniversary of move-in or another fixed day. The math is the same, the prorated period runs from the move-in date through the day before the next billing date, but it can cross into the next month. When that happens, the calculator charges each day at *its own month's* daily rate. Example: $1,500 rent, move-in July 20, billed on the 15th → 12 July days + 14 August days at $48.39/day = $1,258.06, with the first full cycle billed August 15.
A "month" can be 28, 29, 30, or 31 days, so a flat daily rate is never quite right. This calculator always divides by the actual number of days in the calendar month in question, including 29 days for February in leap years, so the daily rate is exact for every month. (Some landlords prefer a 30-day "banker's month" or a 365-day annualized rate; if your lease specifies one of those, follow the lease.)
Yes. On a move-out, the tenant owes rent from the regular billing date through the last day of occupancy, at the same daily rate. Quick trick: enter the day *after* the move-out as the "move-in date", the result is the slice of the cycle the tenant does not owe; subtract it from a full month's rent (exact whenever the cycle stays within one calendar month). The tool's move-out tooltip walks through an example.
Prorated rent is a partial month's rent for the days a tenant actually occupies the unit, typically charged when someone moves in after the regular billing date. It equals the daily rate (monthly rent ÷ days in that month) times the number of days from move-in through the day before the next billing date.
Divide the monthly rent by the number of days in that calendar month to get the daily rate, then multiply by the billable days. Example: $1,500 rent, move-in July 15, billed on the 1st → $1,500 ÷ 31 = $48.39/day × 17 days = $822.58.
The prorated period runs from your move-in date through the day before the next billing date, even when that crosses into the next month. The calculator charges each day at that month's own daily rate, so cross-month periods are handled exactly.
It always uses the actual number of days in each calendar month, 28 or 29 for February (29 in leap years), 30 or 31 elsewhere, so the daily rate is exact for every month rather than an approximation.
In months with fewer than 31 days, the bill simply falls on the last day of that month, and the prorated period counts up to the day before. The calculator adjusts this automatically.
Yes. For a move-out you owe rent from your billing date through your last day. Enter the day after your move-out as the "move-in date", the result is the portion of the cycle you don't owe; subtract it from a full month's rent (exact when the billing cycle stays within one calendar month).
