Important Notes

Prices shown are retail / pay-as-you-go rates. Enterprise agreements, reservations, and savings plans may reduce actual costs.
Monthly estimates are based on 730 hours/month (Azure standard).
Consumption-based services (e.g., Functions, Data Factory) show base/minimum costs only.
Network egress, transactions, and data transfer costs are not included.
