cache.t3.medium pricing and specs in US East (N. Virginia)

2 vCPU · 3.09 GiB · Up to 5 Gigabit · intel

$0.0680/hour on-demand · $50/month (Redis, Default)

cache.t3.medium is a burstable general-purpose ElastiCache instance with 2 vCPU and 3.09 GiB, generation 3 of the t family. On-demand it costs $0.0680 an hour, about $50 a month if it runs all month. A one-year commitment with nothing up front works out at $0.0460 an hour and pays for itself above roughly 493 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.0307 an hour, 55% below on-demand. The newer cache.t4g.medium offers the same size for $0.0650 an hour, 4% less and moves to Graviton. US East (N. Virginia) is already the cheapest region for cache.t3.medium.

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.
