AWS EC2 Monthly Cost Calculator
Estimate your monthly EC2 bill including compute, EBS storage, and data transfer.
Tip: prices are approximate reference values and vary by exact instance generation, tenancy, and billing rules.
Why use an AWS EC2 calculator?
EC2 is flexible, but that flexibility can make pricing feel complicated. You choose an instance type, region, operating system, storage, bandwidth, and purchase model, and each decision changes your monthly bill. An AWS EC2 calculator gives you a quick planning number so you can size infrastructure before launching.
Whether you are running a small app, hosting internal services, or scaling customer workloads, estimating compute cost early helps prevent budget surprises. It also improves architecture decisions: a right-sized instance plus smart scheduling is often much cheaper than overprovisioning.
How this EC2 cost calculator works
This calculator combines three common cost components:
- Compute: hourly instance rate × number of instances × hours/day × days/month
- EBS storage: GB per instance × number of instances × EBS cost per GB-month
- Data transfer out: total GB out × price per GB
If you have a Savings Plan or Reserved Instance, you can apply a discount percentage to estimate reduced monthly spend.
Input fields explained
1) Region
Region matters because EC2 prices differ globally. In general, North Virginia is among the lowest-cost options, while regions with higher operational costs may be more expensive. Always balance price with latency, compliance, and data residency.
2) Operating System
Linux usually has lower hourly pricing than Windows because Windows includes licensing costs. If your workload can run on Linux, you may reduce compute spend significantly.
3) Instance type
Different families are optimized for different tasks:
- t-series: burstable and low cost for lightweight workloads
- m-series: balanced CPU and memory for general-purpose services
- c-series: compute-optimized for CPU-heavy jobs
- r-series: memory-optimized for in-memory processing and caches
- g-series: GPU workloads such as ML inference or graphics
4) Storage and transfer
Many teams underestimate non-compute line items. EBS volumes accumulate cost over time, and outbound data transfer can grow fast in public-facing systems. For realistic planning, include both from day one.
Example monthly estimate
Imagine a web application running two t3.medium Linux instances in us-east-1, 24/7:
- Compute: 2 instances × 24 hours × 30 days × hourly price
- EBS: 50 GB per instance × 2 × EBS rate
- Data out: 100 GB × transfer rate
Add a 20% discount for a committed purchase model and compare total monthly versus annual projected spend. This gives a quick, actionable baseline for engineering and finance planning.
Ways to lower EC2 cost
- Right-size instances using CloudWatch metrics and avoid idle capacity.
- Schedule non-production environments to shut down outside working hours.
- Use Savings Plans or Reserved Instances for steady-state workloads.
- Move fault-tolerant, interruptible jobs to Spot Instances.
- Clean up unattached EBS volumes and old snapshots regularly.
- Use architecture patterns that reduce outbound data transfer where possible.
Important pricing notes
This page is a practical AWS EC2 pricing estimator, not an official billing tool. Real invoices may include additional charges such as Elastic IPs, load balancers, NAT gateway data processing, detailed monitoring, taxes, and support plans. For production commitments, validate numbers against the official AWS Pricing Calculator and your Cost Explorer reports.
