AWS IOPS Cost Calculator
See where your EBS and RDS IOPS bill is hiding — gp3, io2, io2 Block Express, and RDS provisioned storage. us-east-1 pricing.
Which storage type?
Pick the volume type for your workload. Pricing is for us-east-1 (other regions vary by ~5–15%).
Who This Tool Is For
Cloud engineers, database admins, and FinOps leads sizing EBS volumes or RDS storage. If you're staring at a Cost Explorer "EBS:VolumeIOPS-Other" line item wondering where the money went, this tool maps it back to the volume specs you provisioned.
Why We Built This Tool
AWS storage pricing has three moving parts (storage GB, IOPS, throughput) and at least four free-tier baselines that change between gp3, io2, and RDS. The pricing calculator inside the AWS console is correct but slow — engineers want a single page that shows the full bill in seconds. We built this from real client cost-audits where over-provisioned IOPS were 15–30% of the storage bill.
What Problem It Solves
- Forecasting before provisioning. Know the cost of "let's just bump it to 16k IOPS" before you click Apply.
- gp2 → gp3 migration math. Quantify the savings before you cut a change ticket.
- io2 tier breaks. See where the 32k and 64k IOPS tier breakpoints land for your volume.
- RDS storage right-sizing. Confirm whether scaling GB up to claim free baseline IOPS beats provisioning extra IOPS.
Pair this with our RDS consulting or cloud cost optimization engagement to actually claw the IOPS spend back.
Frequently Asked Questions
Why are gp3 IOPS free up to 3,000?
gp3 includes a baseline of 3,000 IOPS and 125 MB/s throughput at no extra cost — independent of volume size. You only pay for IOPS above that baseline. This is the single biggest gp3 advantage over gp2 (where IOPS scaled with GB).
When does io2 Block Express make sense?
io2 Block Express unlocks single-volume IOPS up to 256,000 and throughput up to 4,000 MB/s with sub-millisecond latency. It's typically the right call for SAP HANA, large Oracle databases, and SQL Server workloads where you would otherwise stripe multiple io2 volumes — the storage and IOPS rates are the same as standard io2, but the per-volume ceiling is 4× higher.
Do RDS IOPS prices match EBS?
No. RDS gp3 has different free-baseline rules (12,000 IOPS and 500 MB/s included once your volume is ≥400 GB). RDS io1 and io2 are flat $0.10/IOPS-month versus EBS io2's tiered pricing. The RDS-* options in this tool model the RDS-specific rates, not raw EBS rates.
How accurate is this estimate?
It uses published us-east-1 list prices and matches the AWS Pricing Calculator within $1 for the configurations we tested (gp3, io2 single-tier and multi-tier, RDS gp3 above and below the 400 GB free-baseline threshold). For accurate forecasting in non-us-east-1 regions, multiply by ~1.05–1.15.
Does this include snapshot costs?
No — this calculator covers the live volume only. EBS and RDS snapshots are billed separately ($0.05/GB-month for standard EBS snapshots; RDS backup storage is free up to your DB size, then $0.095/GB-month). Snapshot bills tend to grow silently — DLM lifecycle policies and snapshot archive tier are usually the right next step.
What about cross-region pricing?
All numbers are us-east-1. Frankfurt and Tokyo are typically ~10% higher; Sydney and São Paulo can be 15%+ higher. The methodology stays identical — only the per-unit rates change.
