How much does Azure Cosmos DB cost per month?
Prices range from $0.15/month for Premium SSD Managed Disk - Premium SSD Managed Disk to $16,388.50/month for E64s - E64s on On-Demand pricing in eastus.
Does Azure Cosmos DB have a free tier?
Azure offers various free tier options. Check the official Azure pricing page for the most current free tier details for Cosmos DB.
How many Azure Cosmos DB pricing tiers are available?

What pricing models does Azure Cosmos DB offer?
Azure Cosmos DB offers On-Demand (pay-per-hour, no commitment), Reserved/Committed Use (1-3 year commitments for significant discounts), and in some cases Spot/Preemptible pricing for interruptible workloads at the lowest cost.
Is a managed database worth the extra cost over self-hosted?
Managed databases cost 20-40% more than running your own on a VM, but include automated backups, patching, failover, and monitoring. For most teams the operational savings outweigh the price premium. Self-hosting makes sense only when you need custom configurations or have dedicated DBA expertise.
What is included in managed database hourly pricing?
Hourly pricing covers the compute instance, OS license, and database engine. Storage, backups, and data transfer are billed separately. Some providers bundle a limited amount of backup storage. Always check for I/O costs, which can be significant for write-heavy workloads.
