m5a.8xlarge pricing and specs in US West (Oregon)

32 vCPU · 128 GiB · Up to 10 Gigabit · AMD EPYC 7571

$1.3760/hour on-demand · $1,004/month (Linux, Shared)

m5a.8xlarge is a general-purpose EC2 instance with 32 vCPU and 128 GiB, generation 5 of the m family. On-demand it costs $1.3760 an hour, about $1,004 a month if it runs all month. A one-year commitment with nothing up front works out at $0.8670 an hour and pays for itself above roughly 459 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.5174 an hour, 62% below on-demand. The newer m6g.8xlarge offers the same size for $1.2320 an hour, 10% less and moves to Graviton. Across regions the cheapest place to run m5a.8xlarge is Asia Pacific (Mumbai) (ap-south-1) at $0.8890 an hour, 35% 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.

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.
