Which pricing model does BigQuery use for on-demand query execution?

Accepted Answer

BigQuery's on-demand query execution pricing is based on the amount of data processed. This is because the correct answer, per bytes of data processed, directly correlates with the computational resources used. Conversely, options like per query execution time or per number of rows returned do not accurately reflect resource utilization. Per bytes processed is the most accurate measure.
