AWS Monthly Charges Estimator
Estimate your potential monthly AWS costs for common services like EC2, S3, and RDS. This calculator provides a simplified estimate based on on-demand pricing in the US East (N. Virginia) region (us-east-1) for specific instance types and storage tiers. Actual costs may vary based on region, instance type, usage patterns, reserved instances, savings plans, and other AWS services.
EC2 (Compute) – On-Demand t3.micro Linux
S3 (Storage) – Standard Storage
Data Transfer Out (to Internet)
RDS (Database) – On-Demand db.t3.micro MySQL
Estimated Monthly Costs:
EC2 Cost: $0.00
S3 Cost: $0.00
Data Transfer Out Cost: $0.00
RDS Cost: $0.00
Total Estimated Monthly AWS Cost: $0.00
Understanding Your AWS Charges with This Estimator
Amazon Web Services (AWS) offers a vast array of cloud computing services, and understanding their pricing can be complex due to the pay-as-you-go model, various instance types, storage tiers, data transfer costs, and regional differences. This AWS Charges Estimator is designed to give you a simplified, quick overview of potential monthly costs for some of the most commonly used services.
How AWS Pricing Works (Simplified)
AWS pricing is generally based on consumption. You pay for what you use, with different rates for different services and usage tiers. Key factors influencing your bill include:
- Compute (EC2): Billed per hour or second, depending on the instance type and operating system. Factors include instance type (CPU, RAM), region, and purchase option (On-Demand, Reserved Instances, Spot Instances).
- Storage (S3): Billed per gigabyte (GB) stored per month, with different tiers for standard, infrequent access, and archival storage. Data transfer out of S3 also incurs charges.
- Databases (RDS): Similar to EC2, RDS instances are billed per hour, based on instance type, database engine, and region. Storage and I/O operations for the database also contribute to costs.
- Data Transfer: Data transferred *out* of AWS to the internet is typically charged per GB, often with a free tier for the first gigabyte. Data transferred *in* to AWS is generally free.
Services Included in This Calculator
To provide a practical estimate, this calculator focuses on the following common AWS services and their on-demand pricing in the US East (N. Virginia) region (us-east-1):
-
EC2 (Elastic Compute Cloud) – On-Demand t3.micro Linux:
This estimates the cost for running a basic general-purpose virtual server. The
t3.microinstance type is often part of the AWS Free Tier for new accounts, but this calculator uses the standard on-demand rate of $0.0104 per hour for Linux instances. You input the number of instances and the average hours each instance runs per month. -
S3 (Simple Storage Service) – Standard Storage:
This calculates the cost for storing data in S3's standard storage class. The rate used here is $0.023 per GB per month for the first 50 TB. You input the average amount of data (in GB) you expect to store monthly.
-
Data Transfer Out (to Internet):
This accounts for data leaving AWS to the public internet. The first 1 GB per month is typically free. After that, the rate used is $0.09 per GB. You input the total amount of data (in GB) transferred out per month.
-
RDS (Relational Database Service) – On-Demand db.t3.micro MySQL:
This estimates the cost for a managed MySQL database instance. The
db.t3.microinstance type is a small, general-purpose database instance, priced at approximately $0.017 per hour. You input the number of RDS instances and their operational hours per month.
How to Use the Calculator
- Enter EC2 Details: Specify how many EC2 t3.micro instances you plan to run and for how many hours each month (e.g., 730 hours for always-on).
- Enter S3 Storage: Input the average amount of data in GB you expect to store in S3 Standard storage each month.
- Enter Data Transfer Out: Provide the total amount of data in GB that your applications will transfer from AWS to the internet monthly.
- Enter RDS Details: Specify how many RDS db.t3.micro MySQL instances you plan to run and for how many hours each month.
- Click "Calculate AWS Charges": The calculator will then display the estimated monthly cost for each service and a total estimated monthly bill.
Example Calculation:
Let's say you want to estimate costs for:
- 2 EC2 t3.micro instances, running 730 hours/month each.
- 250 GB of S3 Standard storage.
- 50 GB of data transfer out to the internet.
- 1 RDS db.t3.micro MySQL instance, running 730 hours/month.
Using the rates above:
- EC2: 2 instances * 730 hours/instance * $0.0104/hour = $15.18
- S3: 250 GB * $0.023/GB = $5.75
- Data Transfer Out: (50 GB – 1 GB free) * $0.09/GB = $4.41
- RDS: 1 instance * 730 hours/instance * $0.017/hour = $12.41
- Total: $15.18 + $5.75 + $4.41 + $12.41 = $37.75
This calculator would show an estimated total monthly cost of $37.75.
