EC2 r6i instance prices

The r6i series is a memory optimized EC2 line running on Intel Xeon 8375C (Ice Lake). It has 9 sizes, from the r6i.large with 2 vCPUs and 16 GiB to the r6i.32xlarge with 128 vCPUs and 1024 GiB, and it is memory-heavy with a median of 8.0 GiB per vCPU.

In US East the Linux on-demand price runs from $0.1260/hour to $8.06/hour, or $91.98 to $5,887 a month. The median price per vCPU-hour across the series is $0.0630.

Every size costs the same $0.0630 per vCPU-hour, so price scales linearly: doubling the size doubles the bill, and two smaller instances cost exactly as much as one larger one. That makes it easy to start small and resize later without changing your unit cost. All sizes are sold in the same 12 of the 12 regions we track.
