$0.4310/hour on-demand · $315/month (Redis, Default)

cache.r5.xlarge is a memory-optimized ElastiCache instance with 4 vCPU and 26.32 GiB, generation 5 of the r family. On-demand it costs $0.4310 an hour, about $315 a month if it runs all month. A one-year commitment with nothing up front works out at $0.2950 an hour and pays for itself above roughly 499 hours a month; below that, on-demand is cheaper.

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.
