Google has introduced BigQuery slot autoscaling as a public preview feature, allowing the number of slots inside of a reservation to be scaled up and down as needed for running workloads.
The new billing model is based on the "pay-for-what-you-use" approach and bills by a construct called "slot/hour", which is just the price for using a single slot for an hour billed by the second.
The cost per slot/hour for the public preview is set at $0.06 USD per slot/hour. Autoscaling allows for annual commitments in sets of 100 slots for $0.05 USD per slot/hour. DoiT has created a calculator to determine pricing and compare costs.
