Understanding AWS EC2 Costs
Amazon Elastic Compute Cloud (EC2) provides scalable virtual servers (instances) in the cloud. The cost of running an EC2 instance is influenced by several factors, primarily the instance type, usage duration, storage, and data transfer. This calculator helps estimate your monthly expenditure based on common configurations.
Key Cost Components:
Instance Type & Usage: Different instance types (e.g., t2.micro, m5.large) have varying pricing due to differences in CPU, RAM, storage, and networking capacity. Costs are typically calculated per hour.
On-Demand Pricing: This calculator assumes on-demand pricing, which offers the flexibility to pay by the hour or second without long-term commitments.
Storage (EBS): Elastic Block Store (EBS) volumes are persistent storage devices attached to your EC2 instances. You pay for the provisioned storage capacity (GB) and sometimes for I/O operations, though this calculator focuses on provisioned capacity cost.
Data Transfer: Data transferred out of AWS (to the internet or other regions) typically incurs charges. Data transferred *in* to AWS is usually free.
How the Calculator Works:
The total estimated monthly cost is calculated as follows:
Instance Cost:
Instance Cost = (Price per Hour) * (Usage Hours per Day) * (Usage Days per Month)
If a custom instance type is selected, the price entered by the user is used. Otherwise, the price associated with the selected instance type is applied.
Storage Cost:
Storage Cost = (Additional Storage in GB) * (Storage Cost per GB/Month)
Data Transfer Cost:
Data Transfer Cost = (Data Transfer Out in TB) * (Data Transfer Cost per TB/Month)
Total Monthly Cost:
Total Monthly Cost = Instance Cost + Storage Cost + Data Transfer Cost
Note: AWS pricing can be complex and vary by region. This calculator provides a simplified estimate. Additional costs may apply for features like Elastic IPs, Load Balancers, NAT Gateways, specific EBS volume types (e.g., IOPS), and other AWS services. Always refer to the official AWS Pricing page for the most accurate and up-to-date information for your specific region and configuration.
