Hello Mir Karim,
With the Basic tier, you'll only pay for the Azure services you actually use. There's no minimum fee or upfront commitment.
The primary tool for monitoring your costs is Azure Cost Management + Billing in the Azure Portal:
- Go to the Azure Portal
- Search for "Cost Management + Billing"
- Here you'll find dashboards showing your current costs, forecasts, and usage breakdown
