Prorated rent is the reduced, partial-month amount a tenant pays when their occupancy doesn’t line up with the full rent cycle — typically a mid-month move-in or move-out. Instead of a full month, they’re charged only for the days they actually have the unit.
The usual method is to find a daily rate, then multiply by the days occupied: divide the monthly rent by the number of days in that month (some landlords use a flat 30-day month instead), then multiply by the days the tenant holds the unit. On $1,500 rent for a move-in on the 21st of a 30-day month, that’s $50 a day times 10 days, or $500.
Because the day-count convention (actual days versus a flat 30) changes the result, name the method you use in the lease so a move-in or move-out charge never comes as a surprise. Aptoria applies your chosen convention automatically and records it on the tenant’s ledger.
