The usage screen displays the estimated cost for the current month. It also breaks down usage per day.
Storage is calculated using an average data storage for each table over each day. Table usage is calculated every minute. For example, let’s say you inserted 1MB of data at 12:00PM and didn’t insert any more data. Your usage for the day would be 500kB.
Even though your data is replicated multiple times to ensure redundancy and availability, it is only counted once.
Use retention settings to purge data no longer used and it will not be counted in the usage calculation.
See Data Types for details on storage usage per data type.
Inserts are calculated in realtime and are summarized per day over all tables.
Queries are also calculated in realtime and summarized over all tables.
