google cloud platform – The Cost of BigQuery in GoogleCloudPlatform

I would like to build a data analysis infrastructure but do not know the cost required.

I plan to use BigQuery.
The data to be referenced is not the data stored in GoogleCloudStrage,
I want to refer to data in DeltaLake format stored in GCS.

I understand that storage and communication fees are required.
Other than that, I do not know what other elements or costs are necessary.

please tell us about the following items.

・BigQuery query engine Pricing(cost) elements and amounts
　(In particular, do we need to charge for operational costs from BigQuery to GCS?)
・Pricing(cost) of transferring data from GCS to BigQuery
・Pricing(cost) to execute a query in BigQuery

Please help me.
Thank you.
