Hello Vinod,
Greetings! Welcome to Microsoft Q&A Forum.
Creating resource groups does not incur any costs by itself. These groups serve as logical containers for your Azure resources, allowing you to organize and manage them effectively.
The creation of a storage account itself doesn’t directly result in charges. However, the usage of that storage account (such as storing data, transferring data, or accessing it) will incur costs. These costs depend on factors like the type of storage (e.g., standard, premium), the amount of data stored, and data transfer.
Pricing for Azure Storage is here. It is highly dependent upon what options you chose as to how much you pay. Storage is generally charged based upon how much you store and the operations to read/write it. So if you created a storage account and stored 1 GB in it then you'd be paying for the storage + the cost of writing that data + any reads.
