For BigQuery, you can now see how much a query will cost before running it
May 6th, 2022
This new feature has been enabled for all customers on business and enterprise plans. Next to the Run button, you will see an estimate for how many bytes of data the query will process. Then, on top of that, we have added a cost estimate using a standard conversion $5.00 per TB. If your query has an error, you will see an error icon, and when you hover, you will see exact details on the error. Check out our BigQuery documentation for more details.
