Calculate accurate monthly costs for Amazon EC2 instances across different instance types, regions, and pricing options. Compare on-demand, reserved instances, and spot pricing to find the most cost-effective solution for your workload.
Amazon EC2 cost is the price you pay to run virtual server instances in AWS, billed primarily by the second (with a 60-second minimum) based on the instance type, region, and pricing model you choose. The core estimate is Instance cost = hourly rate × hours running × number of instances, then you add storage (EBS volumes priced per GB-month), data transfer, and any provisioned features. Pricing models change the hourly rate: On-Demand pays the full published rate with no commitment, Reserved Instances and Savings Plans discount it in exchange for a 1- or 3-year commitment, and Spot Instances offer up to ~90% off unused capacity that AWS can reclaim.

Plan your AWS spending with precise cost estimates before deploying infrastructure.
Compare reserved vs on-demand vs spot to save up to 72% on compute costs.
Choose the optimal instance type for your workload without overspending.
Account for EBS storage and data transfer charges often overlooked in estimates.
On-Demand has no commitment but highest cost. Reserved Instances offer 1-3 year commitments with 30-72% savings. Spot Instances bid on unused capacity for up to 90% savings but can be interrupted.
T3 instances are great for burstable workloads. M5 for general purpose. C5 for compute-intensive tasks. R5 for memory-intensive applications like databases.
Reserved Instances can save 30-40% with no upfront, 40-60% with partial upfront, and up to 72% with all upfront payment on 3-year terms.
Spot instances can be interrupted with 2 minutes notice. They're ideal for stateless, fault-tolerant workloads like batch processing, but not recommended for databases or critical services.
gp3 is the best value for most workloads. gp2 is legacy but still widely used. io1 for highest IOPS. st1 for throughput-intensive sequential workloads. sc1 for cold data storage.
