Cloud Block Storage Cost Comparison Calculator

Enter one shared workload for every provider: volume count, capacity per volume, IOPS, throughput, billable disk hours, capacity overhead, and retained snapshot storage.

Each provider plan can then use its own capacity rate, included performance baseline, extra IOPS price, additional throughput price, snapshot rate, recurring cost, and migration cost.

The result ranks configured plans by monthly planning cost and also shows monthly operating cost, cost per volume, cost per provisioned GiB, budget position, and first-year cost.

Cloud block storage is normally billed from provisioned capacity rather than the amount of data currently used. Capacity can continue to generate charges when a virtual machine is stopped but its disk remains provisioned.

Use capacity overhead for free-space policy, growth, temporary copies, deployment overlap, or operational headroom. Use billable disk hours when volumes exist for less than a complete planning month.

A 730-hour month is used only as a consistent comparison base. Provider billing systems can prorate usage by seconds or other billing granularity.

AWS EBS gp3 includes a baseline of 3,000 IOPS and 125 MB/s per volume before additional provisioned performance is charged.

Azure Premium SSD v2 also provides a 3,000 IOPS and 125 MB/s baseline, while Google Hyperdisk Balanced uses a 3,000 IOPS and 140 MB/s baseline in its current pricing model.

The calculator applies each baseline per volume and charges only the entered performance above it. Change every rate and baseline when your region, storage class, or provider configuration differs.

Snapshot charges are based on retained snapshot data, which can be lower than provisioned disk capacity when snapshots are incremental or compressed.

Enter an average monthly snapshot amount rather than assuming every snapshot is a full copy. Restore, retrieval, cross-region movement, instant snapshot, archive minimum-retention, and replication charges are not automatically added.

Use the provider documentation below to collect the exact current regional rate before making a purchasing decision.

Begin with the provider region and storage class that matches your planned architecture. Replace every default price with the current rate from the official provider calculator, pricing page, quote, or invoice.

Compare both monthly operating cost and first-year cost. Migration, testing, data movement, application downtime, and operational learning can make a nominally cheaper service more expensive during the first year.

Review performance limits as well as price. A plan that cannot deliver the required latency, IOPS, throughput, durability, attachment count, or recovery target is not an equivalent option.
