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 — 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
