# AWS EC2 Cost Calculator

- **URL:** https://codeasystem.com/calculators/developer/aws-ec2-cost-calculator/
- **Category:** developer
- **Description:** Estimate hourly, monthly and yearly EC2 on-demand cost for common us-east-1 instance types from a static snapshot price table.
- **Primary output:** Estimated monthly cost (1 × t3.medium): $30.37

## Inputs
- Instance type (name: `instanceType`, type: select)
- Hours per month (name: `hours`, type: number, example: 730)
- Instance count (name: `instances`, type: number, example: 1)

## Outputs
- Estimated monthly cost (1 × t3.medium): $30.37
- Hourly cost: $0.04
- Yearly cost: $364.42
- List rate: $0.0416/hour per instance

## Formula / methodology
```
monthly = rate($/h) × hours × instances   yearly = monthly × 12
```

On-demand list rates are multiplied by running hours and instance count; yearly cost simply scales the month. The table holds static us-east-1 Linux on-demand snapshot prices checked August 2026; no live AWS API is queried.

## Assumptions & limitations
- us-east-1, Linux, shared tenancy, on-demand pricing only.
- Static us-east-1 on-demand snapshot prices checked August 2026; AWS changes pricing frequently; always confirm current rates. Savings Plans/Reserved Instances/Spot change effective prices dramatically.
- EBS volumes, data transfer and elastic IPs bill separately.

## How to use
1. **Pick an instance family**; t3 burstable for dev/web, m5 general, c5 compute-bound, r5 memory-hungry.
2. **Set hours and fleet size**; 730 covers always-on; lower figures model office-hours or autoscaled averages.
3. **Confirm live pricing**; Treat the result as an order-of-magnitude planning figure and verify against the AWS console before committing.

## Example
One t3.medium running the standard 730-hour month costs 0.0416 × 730 ≈ $30.37/month; about $364/year before any discounts.

Result for these inputs:

```
Estimated monthly cost (1 × t3.medium): $30.37
```

## About this calculator
### On-demand is the most expensive baseline

Steady workloads cut 30–60% with one- or three-year Savings Plans or Reserved Instances; interruptible batch work drops up to 90% with Spot. Use on-demand figures as the ceiling, then negotiate down from there.

### What the hourly rate hides

EBS gp3 storage (~$0.08/GB-month), snapshots, inter-region transfer and public IPs all bill separately. Production stacks often spend more outside the instance line than on it; budget accordingly.

## FAQs
### Which region are these prices for?

us-east-1 (N. Virginia), generally the cheapest. Other regions run roughly 10–40% higher.

### Does this include the free tier?

No. New accounts get 750 t3.micro or t2.micro hours monthly for 12 months; subtract that manually if applicable.

### How current is the price table?

Snapshot checked August 2026. AWS revises prices periodically; always confirm in the console for spend decisions.
