i3.xlarge pricing and specs in US West (Oregon)

4 vCPU · 30.5 GiB · Up to 10 Gigabit · Intel Xeon E5-2686 v4 (Broadwell)

$0.3120/hour on-demand · $228/month (Linux, Shared)

i3.xlarge is a storage-optimized EC2 instance with 4 vCPU and 30.5 GiB, generation 3 of the i family. On-demand it costs $0.3120 an hour, about $228 a month if it runs all month. A one-year commitment with nothing up front works out at $0.2140 an hour and pays for itself above roughly 500 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.1320 an hour, 58% below on-demand. The newer i4g.xlarge offers the same size for $0.3089 an hour, 1% less and moves to Graviton. Across regions the cheapest place to run i3.xlarge is US East (N. Virginia) (us-east-1) at $0.3120 an hour, 0% below US West (Oregon).

Newer generations of the same size

Same family letter and size in a newer generation, ranked by price. “vCPU per $” uses vCPU as the performance proxy — newer chips usually add more, so it is a floor.

Caveat: instance price is only part of the bill. Cross-region and internet data transfer, latency to your users, data-residency rules and service availability can outweigh a few percent on compute.

Public AWS list prices (USD), refreshed nightly (catalog 2026-11-06). RI and Savings Plan rates are effective hourly (upfront amortised over the term) and are charged for every hour of the term. Excludes taxes, data transfer and storage. How these numbers are sourced and checked. Not affiliated with Amazon Web Services.

List prices are where it starts. Your bill is where it matters.

TruCost reads your actual AWS usage and tells you which of these commitments you should really buy, what your idle capacity costs, and where every dollar of the bill goes. Thirty minutes on your own data.
