When comparing the current month across the Monthly and Daily intervals in FlexReporting you may find that the two differ in the total returned.
This is due to how the Daily interval operates, you will only be able to select the current day as the End Date e.g. for October 20th, you would only be able to select 20/11/25 as the End date.
Due to this limitation you will find that the total cost value across the two months won't always align when you have Reservations or Savings Plans of the No Upfront payment type.
This is due to the recurring fees associated with No Upfront Savings Plans, and Reservations being present across the entire month when using the Monthly interval, while being constrained when using the Daily interval due to the limitation of the End Date selector.
Using the previous example date 20/11/25:
Reporting using the Monthly interval would include all Usage up until the 20/11/25 + Savings Plan / Reservation Recurring fees through to 31/10/25, while reporting using the Daily interval would include all Usage up until the 20/11/25, but not include the Savings Plan / Reservation Recurring fees through to 31/10/25 as you cannot select a date greater than 20/11/25.
