The monthly rollover let you carry over unused upload allowance for one additional month.

For instance for a PRIVILEGE account :

• If in January you upload 500 MB of photos then in February you start with a new 500 MB (No carry over the next month).
• If in February you upload only 300 MB of photos then the unused monthly upload allowance (200 MB remaining) rollover into next month. Then you will start March with a fresh 700 MB (500 MB + 200 MB).
  - If in March you upload more than 500 MB then in April you will not benefit from rollover.
  - If in March you upload less than 500 MB then in April you will benefit a rollover of unused upload allowance equal to 500 MB minus the volume of new photos uploaded in March

The approach helps clients to balance high and low usage months.
