The pricing for AWS Athena is primarily influenced by the amount of data scanned during each query. Athena charges are determined by the total volume of data that your queries scan. There are no upfront costs, no minimum fees, and you only pay for the queries you run.

• Data Scanned: The cost of AWS Athena is based on the volume of data scanned by each query. You're charged $5 per terabyte of data scanned.
  ‍
• Data Format and Compression: The size of the data being scanned can be influenced by the data format and whether the data is compressed or not. Columnar formats, such as Apache Parquet and ORC, organize data by column rather than by row, reducing the data that needs to be scanned for column-specific queries. Compression can also reduce the size of the dataset that needs to be scanned.
  ‍
• Partitioning: Partitioning your data in Athena can also help minimize the amount of data scanned by each query, and therefore reduce the cost. Partitioning divides your table into parts based on the values of particular columns and stores the parts in a separate folder in your Amazon S3 bucket.
