1. What is the AWS Monthly Cost Calculator?

The AWS Monthly Cost Calculator estimates your monthly AWS expenses based on your resource usage, rate per unit, and duration. It helps in budgeting and cost planning for cloud resources.

2. How Does the Calculator Work?

The calculator uses the AWS cost equation:

Where:

• \( Usage \) — Resource consumption in units
• \( Rate \) — Cost per unit in USD
• \( Months \) — Duration in months

Explanation: The equation calculates total cost by multiplying the amount of resources used by the cost per unit and the duration of usage.

3. Importance of AWS Cost Calculation

Details: Accurate cost estimation is crucial for cloud budgeting, resource planning, and avoiding unexpected expenses in AWS environments.

4. Using the Calculator

Tips: Enter usage in units (e.g., GB, hours), rate in USD per unit, and months of usage. All values must be valid (usage > 0, rate > 0, months between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for AWS services?
A: Units vary by service - GB for storage, hours for compute, requests for Lambda, etc. Check AWS pricing pages for specific services.

Q2: Does this include free tier or discounts?
A: No, this calculates full price. For accurate billing including discounts, use the AWS Cost Explorer.

Q3: How often should I recalculate costs?
A: Recalculate whenever your usage patterns change or AWS updates their pricing (typically several times per year).

Q4: Are there other cost factors to consider?
A: Yes, consider data transfer costs, regional pricing differences, and service-specific charges not captured in this simple calculation.

Q5: Can I use this for reserved instances?
A: For reserved instances, use the upfront payment plus the monthly cost over the reservation term.
