Hi @Ervin Wilneder Thank you for posting your question on Microsoft Q&A.
You can explore all the database SQL pricing
SQL Database serverless is best for scenarios where usage is intermittent and unpredictable and you only pay for compute resources you use on a per-second basis, which optimizes overall price performance. Please check this documentation , it will help better help you understand how you can manage your Azure SQL Database costs.
