HOW TO USE THIS CALCULATOR

Estimate your AWS bill in three steps

1

Configure your instances

Select a machine type (e.g. m5.large) and AWS region for each workload. Pricing varies by region — us-east-1 is typically the cheapest baseline.

2

Set usage and quantity

Enter how many days per month each instance runs and how many instances you need. A 24/7 workload is 30 days; dev environments often run 22 or fewer.

3

Compare and decide

Add as many configurations as you like — the estimate totals everything instantly and updates live as you switch pricing plans, regions, or currency.

PRICING MODEL

How EC2 pricing works

EC2 is priced per instance-hour, with the rate set by the instance type and the region it runs in. Instance families target different shapes of work: M for balanced general purpose, C for compute-bound, R and X for memory-heavy workloads, I and D for local storage throughput, and P and G for GPU work. Linux instances bill per second after a sixty second minimum, while some commercial operating systems still bill by the hour, which matters for short-lived or frequently cycled fleets.

The purchase option usually moves the bill more than the instance choice does. On-Demand carries no commitment and the highest rate. Reserved Instances and Savings Plans discount heavily in exchange for a one or three year commitment. Spot uses spare capacity at the steepest discount but can be reclaimed with two minutes of notice. EBS volumes, snapshots, load balancers, and data transfer out of AWS are billed separately from the instance and should be added when budgeting.

What drives your EC2 bill

Instance family and size

Rates scale with vCPU and memory, but not evenly across families. A memory-optimised instance costs considerably more per vCPU than a general purpose one with the same core count.

Region

The same instance type carries different rates by region. us-east-1 is typically the cheapest baseline, while South America and some Asia-Pacific regions carry a noticeable premium.

Purchase option

On-Demand, Reserved Instances, Savings Plans, and Spot can differ by a large multiple for identical hardware. This is usually the single biggest lever on an EC2 bill.

Operating system

Linux carries no licence cost. Windows and commercial Linux distributions add a per-hour licence charge on top of the instance rate, which weighs more heavily on smaller instances.

Storage and transfer

EBS volumes are billed on provisioned capacity whether or not the instance is running, and data leaving AWS is billed per GB. Neither is included in the instance rate.

EC2 pricing questions

How accurate is this EC2 pricing calculator?
Rates are based on published AWS pricing for each region and are refreshed regularly. Your actual bill can differ once EBS volumes, snapshots, data transfer, support plans, and any negotiated discount are included, so treat the output as a close planning estimate rather than an invoice forecast.
