@Ardemius Thank you for your patience over the matter!!!
As mentioned here Cloud Shell billing is based only on the Azure Files share used to persist your data. Your total cost depends on how much you store, the volume and type of storage transactions and outbound data transfers, and which data redundancy option you choose. By default, Azure Cloud Shell creates a locally redundant storage (LRS) account on your behalf with an Azure Files share. For Bash, this share will also contain a 5 GB disk image.
There would not be a cost estimation possible for CloudShell Storage globally since it depends on lot of factors. It normally applies the GRS/ZRS mounted file share storage costs and the associated costs would be too negligible to track. Also the # of transactions on cloudshell would not be huge enough to generate enough charge.
Cloud Shell persists $HOME using a 5-GB image held in your file share
And the charges for the same can be almost considered closer to 0 than 1. Also, you can choose the LRS/ZRS/GRS option using "Advanced Settings" on cloud shell. ( The first time you run the script )
I use it on a regular basis and my monthly costs are almost 0 :)
Hope it helps!!!
