What is the difference between gp3 and gp2 volumes?

gp3 volumes let you independently provision IOPS (up to 16,000) and throughput (up to 1,000 MiB/s) regardless of volume size, with a baseline of 3,000 IOPS included. gp2 volumes scale IOPS with size at 3 IOPS per GB and rely on burst credits for small volumes. gp3 is typically 20% cheaper for equivalent performance.

Does the calculator account for EC2 instance throughput limits?

The calculator focuses on EBS volume-level limits. However, it warns you when your provisioned IOPS or throughput may exceed the EBS-optimized bandwidth of common EC2 instance types, so you can size both the volume and instance together.

About This Tool

The EBS IOPS Calculator helps you determine the performance characteristics and monthly cost of Amazon Elastic Block Store volumes. It covers all major EBS volume types including gp3, gp2, io2 Block Express, io1, st1, and sc1, each with their unique IOPS and throughput baselines. Enter your desired volume size, provisioned IOPS, and throughput to see whether your configuration falls within AWS limits and what it will cost per month. The calculator highlights bottlenecks such as instance-level IOPS caps and burst credit depletion so you can right-size volumes before attaching them to EC2 instances.

When to Use This Tool

•Sizing gp3 or io2 volumes for a database workload that requires predictable IOPS at the lowest cost.
•Comparing the cost-performance tradeoff between gp3 with provisioned IOPS versus io2 Block Express for high-throughput applications.
•Validating that a chosen EBS volume type meets the throughput requirements for big data or streaming workloads on st1.
•Estimating monthly EBS costs during capacity planning for new EC2 fleet deployments.
