No SQL Pricing calculator
Right now you have exactly nothing in your calculator for estimating the cost of a database server in Azure! Any selection in the SQL options redirects you to the "new" VM calculator which doesn't have any options for SQL Server cost calculations.

The new pricing calculator includes SQL Server VMs. When pricing a VM, change the "Type" from "Windows" to "SQL Server". You'll get another drop-down to select web/standard/enterprise.
