c6i.32xlarge pricing and specs in US West (Oregon)
128 vCPU · 256 GiB · 50 Gigabit · Intel Xeon 8375C (Ice Lake)
$5.4400/hour on-demand · $3,971/month (Linux, Shared)
c6i.32xlarge is a compute-optimized EC2 instance with 128 vCPU and 256 GiB, generation 6 of the c family. On-demand it costs $5.4400 an hour, about $3,971 a month if it runs all month. A one-year commitment with nothing up front works out at $3.5986 an hour and pays for itself above roughly 482 hours a month; below that, on-demand is cheaper. The three-year options go down to $2.0846 an hour, 62% below on-demand. The newer c6a.32xlarge offers the same size for $4.8960 an hour, 10% less. Across regions the cheapest place to run c6i.32xlarge is Asia Pacific (Malaysia) (ap-southeast-5) at $5.3312 an hour, 2% 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.
