The move-in day and the move-out day both count as days you pay for. Check your lease: it may name the method your landlord uses.
Divide the monthly rent by the number of days in that month. A 1,500 rent in a 30-day month is 50 a day; in a 31-day month it is about 48.39. Some leases use yearly rent divided by 365 instead, or a flat 30-day month, so check yours.
Moving in on the 18th of a 30-day month means 13 days (the 18th to the 30th, both included). Moving out on the 10th means 10 days. The move-in and move-out days are usually charged.
Daily rate times days is the prorated rent. 50 a day for 13 days is 650.
If two people move into one room mid-month, they split that prorated amount. Everyone already living there pays their normal share minus the new roommate's prorated part for that month.
Mid-month moves are where flats lose track of money. Note the prorated amount, who paid the landlord, and who owes whom before the next full month starts.
For the full months, use the rent split calculator to split rent by room size. Someone leaving? Work through the roommate move-out checklist, and use the free roommate bill agreement template to put the rules in writing.
Divide the monthly rent by the number of days in the month to get a daily rate, then multiply by the number of days you live there that month. For a 1,500 rent and a move-in on 18 November (30 days), that is 50 a day times 13 days, or 650.
Usually yes. Most landlords charge for the move-in day and the move-out day, because you have the keys on both. The calculator above counts both days.
Days in the month is the most common and the easiest to check. The yearly method (rent times 12, divided by 365) gives the same daily rate all year. A 30-day month is simplest but slightly overcharges in February and undercharges in 31-day months. Use whatever your lease says; if it says nothing, agree one method in writing.
Work out the new roommate's prorated share for the days they live there, have them pay that amount, and reduce everyone else's share for that month by the same total. From the next month, use your normal split.
Log the prorated rent as a bill with custom shares, then the regular rent each month. IPaid does this free for one flat: everyone sees what they owe and who has paid.
