Prices

Real AWS prices, one page per instance type.

Pulled straight from the AWS Price List API: on-demand rate, every term and payment option AWS actually sells, and what a day without the reservation costs. Not a quote; verify in the AWS console before you buy.

What makes up an RI price

Four numbers, one blended rate.

Upfront

Paid once at purchase. $0 on No Upfront, the whole commitment on All Upfront.

Hourly

The recurring rate for the rest of the term. $0/hr on All Upfront, since it's already paid.

Effective $/hr

Hourly plus the upfront amortized across the term: the number actually comparable to on-demand.

% off

1 − (effective ÷ on-demand). Every page below shows all three payment options for both terms.
