AWS EBS Monthly Cost Calculator
Estimate your monthly Amazon EBS charges for storage, provisioned performance, and snapshots.
How this AWS EBS cost calculator works
This calculator gives you a practical estimate for monthly Amazon EBS spend. It combines the three major cost drivers most teams care about:
- Volume storage cost based on size (GB), type (gp3, io2, st1, and others), and how long it runs during the month.
- Performance cost for provisioned IOPS and throughput where applicable.
- Snapshot storage cost for both standard and archive snapshot tiers.
AWS EBS pricing in plain English
1) Storage (GB-month)
Every EBS volume type has a base price per GB-month. For example, gp3 generally costs less per GB than io2. If your volume only runs part of the month, this calculator prorates storage using active hours.
2) Provisioned IOPS
Provisioned IOPS SSD volumes (io1/io2) charge for IOPS you reserve. On gp3, a baseline amount is included, and only extra IOPS above baseline are billed.
3) Provisioned throughput (MB/s)
Throughput charges mainly matter for gp3. Like IOPS, gp3 includes baseline throughput and charges only for additional throughput.
4) Snapshots
Snapshots are billed by data stored. Standard snapshots are the common tier; archive snapshots are cheaper but designed for long-term retention and slower restore workflows.
Quick volume type guide
| Volume Type | Best For | Cost Behavior |
|---|---|---|
| gp3 | Most workloads (web apps, dev/stage, general databases) | Low storage price + optional paid IOPS/throughput above baseline |
| gp2 | Legacy SSD setups | Storage-only style pricing; many teams migrate to gp3 for savings |
| io1/io2 | Latency-sensitive, high-IOPS production databases | Higher storage price + explicit IOPS charges |
| st1 | Large, sequential throughput workloads | Cheaper than SSD for certain patterns |
| sc1 | Cold, infrequently accessed data | Lowest HDD price, lower performance |
Example estimate
Suppose you run a 500 GB gp3 volume for the full month, with 6,000 IOPS and 250 MB/s, plus 100 GB of standard snapshots:
- Storage: 500 × gp3 per-GB price
- IOPS add-on: (6,000 − 3,000 included) × IOPS rate
- Throughput add-on: (250 − 125 included) × throughput rate
- Snapshots: 100 × snapshot per-GB price
That total is exactly the kind of breakdown the calculator returns, so you can quickly compare configuration options before making changes in production.
How to reduce EBS spend without hurting performance
Move from gp2 to gp3 where possible
Many environments still use gp2 by default. In many cases, gp3 can provide equal or better performance at a lower cost.
Right-size provisioned IOPS
Over-provisioned IOPS is a common hidden cost. Monitor real utilization and trim to your observed peak plus a reasonable safety margin.
Clean up old snapshots
Snapshots are cheap individually but expensive in aggregate. Apply retention policies and lifecycle rules to remove stale recovery points.
Use archive tier for compliance backups
If restore speed is not critical, archive snapshots can significantly lower long-term storage costs.
Common estimation mistakes
- Ignoring partial-month environments (test stacks that run only during business hours).
- Forgetting snapshot growth over time.
- Assuming all volume types include the same free baseline performance.
- Not accounting for region-by-region price differences.
FAQ
Is this calculator accurate enough for budgeting?
It is great for planning and architecture comparisons. For final reporting, use AWS billing data and your organization discounts.
Does it include EC2 instance cost?
No. This page calculates EBS-related storage and snapshot estimates only.
Do snapshots cost money if I delete the source volume?
Yes. Snapshot data is billed independently until the snapshot itself is deleted.
Can I use this for multi-volume servers?
Yes. Calculate each volume and sum results, or combine sizes if they share the same type and performance settings.
