The formula to prorate is: (Monthly Amount / Total Days in Month) * Number of Days Applicable. This helps in calculating the precise portion of a monthly fee when the service period is less than a full month. For example, if a monthly subscription is $30 and the service is used for 10 days in a 30-day month, the prorated amount would be $(30 / 30) * 10 = $10.
