c5a.8xlarge pricing and specs in US East (N. Virginia)
32 vCPU · 64 GiB · 10 Gigabit · AMD EPYC 7R32
$1.2320/hour on-demand · $899/month (Linux, Shared)
c5a.8xlarge is a compute-optimized EC2 instance with 32 vCPU and 64 GiB, generation 5 of the c family. On-demand it costs $1.2320 an hour, about $899 a month if it runs all month. A one-year commitment with nothing up front works out at $0.7760 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 $0.4632 an hour, 62% below on-demand. The newer c6g.8xlarge offers the same size for $1.0880 an hour, 12% less and moves to Graviton. Across regions the cheapest place to run c5a.8xlarge is Asia Pacific (Mumbai) (ap-south-1) at $0.7520 an hour, 39% below US East (N. Virginia).

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.

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.
