Hi @vziog,

The Azure portal typically aggregates costs from various billing categories (such as DBUs, infrastructure, storage, and networking) based on usage logs and pricing. On the other hand, the query designed by you extracts detailed cost estimates solely based on DBU usage from the system.billing.usage and system.billing.list_prices tables. There may be costs missing in your query, such as:

• Infrastructure costs for virtual machines, storage, or networking.
• Any applicable Azure service fees or extra charges (e.g., premium features or non-resource-specific costs).
