Split a gp3 volume bill into capacity, IOPS above the free 3,000 and throughput above the free 125 MB/s.
gp3 decouples capacity from performance: you pay for every GiB provisioned whether or not it holds data, then pay separately only for IOPS above 3,000 and throughput above 125 MB/s. Because the baseline is free at any volume size, gp3 removes the gp2 trick of over-sizing a volume just to buy IOPS. Every rate here is a user-supplied list price to confirm on the AWS EBS pricing page for your region. It shows whether a volume's bill is driven by capacity or by performance, which decides whether the fix is shrinking the disk, lowering the provisioned IOPS, or moving to io2 or st1.
EBS Volume Cost
cost = GiB x capacity rate + max(0, IOPS − 3000) x IOPS rate + max(0, MB/s − 125) x throughput rate.
cost = GiB x capacity rate + max(0, IOPS − 3000) x IOPS rate + max(0, MB/s − 125) x throughput rate. gp3 decouples capacity from performance: you pay for every GiB provisioned whether or not it holds data, then pay separately only for IOPS above 3,000 and throughput above 125 MB/s.

This calculator takes 8 inputs: Volume size, Provisioned IOPS, Provisioned throughput, IOPS included in the base price, Throughput included in the base price, Capacity price, Provisioned IOPS price, Provisioned throughput price. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
Yes. EBS bills provisioned capacity and provisioned performance for as long as the volume exists, regardless of whether an instance is attached or running. Unattached volumes are one of the most common sources of silent storage spend.
