Blockchain Service Workbench users

Hello,

I was following this tutorial: (https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/blockchain/workbench/deploy.md)

looking at point 6 of "Deploy Blockchain Workbench" is possible to estimate the resulting price?

This is, with the example configuration, with the service always active for a month, what would it cost?

Also, does the cost increase as I add users to an application on the Workbech?

Thank you
