Use our comprehensive AWS Service Calculator to estimate your total monthly infrastructure costs based on typical usage patterns for popular services like EC2, S3, and Data Transfer. Plan your budget accurately and optimize your cloud spending.
AWS Service Calculator: Total Monthly Cost
Detailed Calculation Breakdown
AWS Service Calculator Formula
Total Monthly Cost (M) = (EC2 Cost) + (S3 Cost) + (Data Transfer Cost)
M = (N * H * 730) + (S * C) + (D * T)
Where 730 is the approximate number of hours in a month (24 hours * 30.41 days).
Formula Source: AWS Official Pricing Page | EC2 Pricing Details
Variables Explained
- Number of EC2 Instances (N): The quantity of virtual servers you run.
- EC2 Cost Per Hour (H): The hourly rate of the chosen instance type (e.g., t3.micro, m5.large).
- S3 Storage (S - GB): The total volume of data stored in S3 Standard storage class, measured in Gigabytes.
- S3 Cost Per GB Per Month (C): The monthly cost charged by AWS for 1 GB of S3 storage.
- Data Transfer Out (D - GB): The total volume of data transferred from AWS to the internet (outbound), measured in Gigabytes.
- Data Transfer Cost Per GB (T): The cost charged per Gigabyte for outbound data transfer.

What is an AWS Service Calculator?
An AWS Service Calculator is an essential tool designed to help businesses and developers estimate the potential running costs of their cloud infrastructure before deployment. Because AWS pricing is consumption-based and highly granular, manually calculating monthly expenses across multiple services like EC2, S3, and data transfer can be complex and error-prone.
This calculator provides a transparent, estimated monthly total by segmenting your expenses into key component categories. It allows users to input their anticipated usage metrics—such as the number of instances, gigabytes of storage, and outbound traffic—to get a rapid cost projection. This is crucial for budgeting, optimizing resource usage, and ensuring financial predictability in cloud operations.
How to Calculate Total Monthly AWS Cost (Example)
- Determine EC2 Compute Cost: Multiply your number of instances (e.g., 2), by the hourly cost (e.g., $0.035), and then by 730 hours. (2 x $0.035 x 730 = $51.10).
- Determine S3 Storage Cost: Multiply your total GB of storage (e.g., 200 GB) by the cost per GB per month (e.g., $0.023). (200 x $0.023 = $4.60).
- Determine Data Transfer Cost: Multiply your outbound data (e.g., 50 GB) by the cost per GB (e.g., $0.09). (50 x $0.09 = $4.50).
- Sum the Totals: Add the cost of all components: EC2 ($51.10) + S3 ($4.60) + Data Transfer ($4.50) = $60.20.
Frequently Asked Questions (FAQ)
730 hours is commonly used in cloud cost estimation as a simplified average (24 hours * 30.417 days) to provide a predictable monthly figure for continuously running resources.
No. This model is based on standard On-Demand pricing. RIs and Savings Plans offer significant discounts but require a separate, more complex calculation based on commitment levels.
AWS typically charges for outbound data transfer (egress) but generally does not charge for data moving into the AWS network (ingress). This structure encourages users to host their data and services on AWS.
This simple calculator focuses on the top three cost drivers (EC2, S3, Data Out). For a complete estimate, you would need to add line items for services like RDS, networking components (Load Balancers), and software licenses.
