GP2 to GP3 savings calculator
GP3 costs less per GB than GP2 and adds a free 3,000 IOPS baseline. See what the change is worth across your volumes before you touch anything.
Your GP2 volumes
Paste the JSON, or just a list of sizes in GB (one per line). GP2 volumes are counted automatically.
Estimate uses us-east-1 list pricing: GP2 $0.10/GB-mo vs GP3 $0.08/GB-mo (a 20% storage saving). It excludes the free 3,000 IOPS baseline GP3 adds on top. Actual savings vary by region and your real volume mix; the assessment gives exact numbers.
Your estimate appears here: the monthly and annual saving from moving your GP2 volumes to GP3.
The arithmetic
How the estimate is calculated
- List pricing. GP2 is $0.10 per GB-month and GP3 is $0.08 per GB-month, on us-east-1 list pricing.
- Monthly saving = total GB × $0.02. Annual saving = that figure × 12.
- Your volumes, your browser. Give it a count and an average size, or the raw output of
aws ec2 describe-volumes. Nothing you paste is sent anywhere.
