AWS Pricing Calculator Review
Honest look at AWS's official cost estimation tool: what it does well, where it falls short, and when to use simpler alternatives.
TL;DR
AWS Pricing Calculator is a comprehensive, free tool for estimating AWS costs across 150+ services. It's powerful but complex. Great for detailed architecture planning, overkill for quick "how much will Lambda cost me?" questions. For simple estimates, use focused single-service calculators instead.
What is AWS Pricing Calculator?
AWS Pricing Calculator is a web-based tool at calculator.aws that lets you estimate AWS costs before deploying resources. There are two versions:
Public Version (No Sign-in Required)
- Select from 150+ AWS services
- Configure instance types, storage, and data transfer
- Apply Reserved Instances and Savings Plans discounts
- Compare pricing across AWS regions
- Export estimates as CSV, PDF, or JSON
- Share estimates via unique URL
In-Console Version (May 2025 Update)
- Import historical usage data from your AWS account
- See how existing Savings Plans and Reserved Instances affect estimates
- Three rate views: on-demand, with discounts, and after commitments
- Compare cost impact of migrating workloads across regions
- API access for programmatic cost estimation
- Costs $2 per estimate after 5 free per month
AWS Pricing Calculator vs Cost Explorer
These two AWS tools serve different purposes. Many users confuse them, so here's when to use each:
| Feature | Pricing Calculator | Cost Explorer |
|---|---|---|
| Purpose | Estimate future costs | Analyze past spending |
| Data Source | Manual input (your assumptions) | Actual AWS bills |
| Accuracy | Estimates only (±20-40%) | 100% accurate (real data) |
| Best For | Pre-deployment planning | Cost optimization |
| AWS Account | Not required (public version) | Required |
| Cost | Free (5/month), then $2/estimate | Free |
| Use Case | "How much will this cost?" | "Where did my money go?" |
How to Use AWS Pricing Calculator
The basic workflow is straightforward, but configuring each service can be complex:
- Go to calculator.aws. No sign-in required for the public version
- Click "Create estimate". Start with a blank estimate or sign in for personalized pricing
- Add services. Search for AWS services (EC2, S3, Lambda, RDS, etc.) and add them to your estimate
- Configure each service. This is where it gets complex. For EC2 alone, you'll configure: region, instance type, number of instances, pricing model (on-demand/reserved/spot), storage type and size, data transfer
- View estimate totals. See costs per service and total monthly estimate
- Export or share. Save as CSV/PDF/JSON or share via unique URL

AWS Pricing Calculator FAQ
Common questions about AWS Pricing Calculator
AWS Pricing Calculator is a free web-based tool that helps you estimate the cost of AWS services before you deploy them. You can model workloads by selecting services, configuring resources (instance types, storage, data transfer), and getting monthly cost estimates. It supports 150+ AWS services and can factor in Reserved Instances, Savings Plans, and regional pricing differences.
The public version at calculator.aws is completely free with no AWS account required. However, the new in-console version (launched May 2025) that imports historical usage and estimates full bills charges $2 per estimate after 5 free estimates per month.
AWS costs vary widely based on usage. Small projects typically cost $10-50/month (basic web hosting with t3.micro EC2, small RDS, S3 storage). Medium applications cost $100-500/month (multiple EC2 instances, managed databases, CDN). Enterprise workloads often exceed $1,000+/month. The pay-as-you-go model means you only pay for what you use.
The calculator uses official AWS pricing data and is accurate for the inputs you provide. However, real-world costs often differ because: (1) you may not know exact usage patterns upfront, (2) data transfer costs are hard to predict, (3) hidden costs like NAT Gateway fees ($32/month + data) are easy to miss, and (4) usage patterns change over time. It's best used as a starting estimate, not a final budget.
AWS Pricing Calculator estimates future costs before deployment (planning tool). AWS Cost Explorer analyzes your actual historical spending after deployment (analysis tool). Use the Pricing Calculator when planning new projects, and Cost Explorer to understand and optimize existing AWS spend.
