Are these prices accurate?

Prices are based on published AWS on-demand rates and are updated periodically, but they may lag behind the latest AWS pricing changes. Always verify against the official AWS Pricing Calculator for billing decisions.

What is on-demand pricing?

On-demand instances are billed by the hour (or second for Linux) with no long-term commitment. Reserved Instances and Savings Plans offer significant discounts (up to 72%) for 1- or 3-year commitments.

Why does the Windows price differ?

Windows instances include a Microsoft license fee on top of the base compute cost, which is why they are priced higher than equivalent Linux instances.

Does this include storage or data transfer costs?

This calculator focuses on compute (EC2 instance) costs only. EBS storage, data transfer, NAT Gateway, and other services add to your total AWS bill.

What is the difference between instance families?

General Purpose (M/T series) balances CPU and memory. Compute Optimized (C series) provides more CPU per dollar. Memory Optimized (R/X series) suits databases and in-memory workloads. Storage Optimized (I/D series) offers fast local NVMe storage.
