Monthly Billable Users is based on the MAU (monthly active users) and data points you incur. If a user performs an action in a calendar month, they are counted as an MAU. A data point is an event, event property, or profile property update.
Monthly Billable Users is based on whichever is highest:
- MAU tier limit as defined on your plan,
- The Actual MAU usage, or
- Processed MAU, which is the total data points used divided by allowed data points per MAU. A total of 2000 data points are allowed per MAU. In most cases, users perform fewer than 2,000 data points per month.
