Rent for a partial month from a move-in or move-out date, with three daily-rate methods side by side.
Prorated rent is the daily rate multiplied by the number of days you occupy the home in that month. The daily rate is the monthly rent divided by the days in the month. For a move-in on 15 November with a rent of 1,500.00, November has 30 days, so the daily rate is 50.00. Moving in on the 15th counts the 15th to the 30th, which is 16 days, so the prorated rent is 16 x 50.00 = 800.00. For a move-out the days run from the 1st to the move-out day, so leaving on 10 November is 10 days, or 500.00. The page shows the formula, the days counted and the first and last day of the period, so you can compare it with your lease or your landlord's figure.
Landlords use different conventions, so the page offers three and compares them in a table. Actual days divides by the real length of the month, 28 to 31 days, so a day in February costs more than a day in March. The 30-day month method divides the rent by 30 and multiplies by the real days you occupy, capped at the full monthly rent, as in a California Department of Transportation rent-proration procedure. The yearly method multiplies the monthly rent by 12 and divides by 365, which gives every day the same rate all year. On 1,500.00 rent with a move-in on 15 November, actual days and the 30-day month both give 800.00, and the yearly method gives 789.04. A move-in on the 1st or a move-out on the last day of the month is a full month, so every method returns the full monthly rent, and no partial result is ever above it. None of these is a legal rule. Your lease, or the law where you live, decides which one applies, and some leases state it.
By default the move day is counted, which is called inclusive counting: moving in on the 15th means you pay for the 15th. Some leases start the rent the day after the key handover, or end it the day before the move-out. Switch off Count the move day to see that case. With it off, a move-in on 15 November counts 15 days instead of 16, and a move-out on 10 November counts 9 days instead of 10. The page prorates one calendar month at a time. If your stay crosses a month end, for example 20 March to 10 April, run the calculator once for the move-in month and once for the move-out month, and add the two amounts.
The result is rent only. It does not add a security deposit, utilities, parking, pet fees or taxes, and it does not know your local law. Some places set rules for proration, and many leases fix their own method. The yearly method uses 365 days even in a leap year, so the daily rate is the same in every month, but a full month is always the full monthly rent. Amounts are worked at full precision and rounded to two decimals only when shown. This is an estimate, not legal or financial advice, so confirm the figure with your landlord or your lease before you pay.
Divide the monthly rent by the days in the month to get the daily rate, then multiply by the days you stay. With 1,500.00 rent in a 30-day month, the daily rate is 50.00, so 16 days is 800.00.
Use what your lease says. Without a stated method, actual days is the most common. In February with 28 days, 1,400.00 rent is 50.00 a day, but with a 30-day month it is 46.67 a day. The table shows all three methods. A full month is always the full rent in every method.
By default yes, which is inclusive counting. Moving in on the 20th of a 30-day month counts 11 days: the 20th to the 30th. Switch off Count the move day if your lease starts rent on the next day, which gives 10 days.
Count the days from the 1st of the month up to and including the move-out day. Leaving on the 10th of a 30-day month counts 10 days, so 1,500.00 rent gives 10 x 50.00 = 500.00.
Days are counted on the real calendar and priced at rent / 30, never above full rent. A move-in on the 31st counts 1 day, 1/30 of the rent. A move-in on the 1st, or a move-out on the last day, is a full month: the full monthly rent.
Run it twice. For a stay from 20 March to 10 April, use a move-in on 20 March (12 days of 31) and a move-out on 10 April (10 days of 30), then add the two amounts.
