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.
