To prorate a monthly rate, first determine the daily rate by dividing the monthly rate by the number of days in the month. Multiply this daily rate by the number of days the service or item is used within that month. For example, if the monthly rate is $300 and the month has 30 days, the daily rate is $10. If used for 10 days, the prorated charge is $100. Formula: (Monthly Rate ÷ Days in Month) × Days Used.
