If a customer pays $90 for a monthly service, then cancels on the 20th day of the month, the business may prorate the amount of unused service and adjust the invoice accordingly. For a 30-day month, the daily cost would be $3. Calculating the amount for the 10 days not used would be $3 x 10 or $30. Rental agreements that require rent to be paid on the first day of each month may need to be prorated when a tenant moves in or out in the middle of the month.
