Billing rules

After the RI is purchased successfully, calculation of the reservation term begins. You are charged according to your payment option regardless of whether Pay-As-You-Go instances are matched. We recommend that you choose All Upfront to maximize your savings.

An RI takes effect and is billed on the hour upon successful purchase. It expires at 00:00:00 the day after the term end date. For example, you purchased an RI on February 26, 2019 13:45:00 PM, with a term of one year. The RI took effect on 2019-02-26 13:00:00, and its billing also started from that time. It will expire on 2020-02-27 00:00:00. If you had matchable instances when you purchased the RI, the billing discount first applied to the bill generated from 13:00 to 14:00 on February 26, 2019 till the expiration of the RI.
