i3.16xlarge pricing and specs in US West (Oregon)

64 vCPU · 488 GiB · 25 Gigabit · Intel Xeon E5-2686 v4 (Broadwell)

$4.9920/hour on-demand · $3,644/month (Linux, Shared)

i3.16xlarge is a storage-optimized EC2 instance with 64 vCPU and 488 GiB, generation 3 of the i family. On-demand it costs $4.9920 an hour, about $3,644 a month if it runs all month. A one-year commitment with nothing up front works out at $3.4270 an hour and pays for itself above roughly 501 hours a month; below that, on-demand is cheaper. The three-year options go down to $2.1116 an hour, 58% below on-demand. The newer i4g.16xlarge offers the same size for $4.9421 an hour, 1% less and moves to Graviton. Across regions the cheapest place to run i3.16xlarge is US East (N. Virginia) (us-east-1) at $4.9920 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.

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.

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.
