Billing details

The term of a reserved instance starts immediately after it is purchased. You are charged based on the payment option that you selected regardless of whether the reserved instance is matched to pay-as-you-go instances. We recommend that you select All Upfront to maximize your savings.

A reserved instance takes effect and is billed starting on the hour of your purchase. The reserved instance expires at 24:00:00 of the term end date. For example, if you purchase a reserved instance with a one-year term at 22:45:00 on May 1, 2020, the reserved instance takes effect and is billed starting from 22:00:00 on May 1, 2020. The reserved instance expires at 24:00:00 on May 2, 2021. If you already have eligible pay-as-you-go instances when you purchase a reserved instance, the reserved instance is applied to offset the bills generated by the pay-as-you-go instances starting from the hour of 22:00 to 23:00 on May 1, 2020 until the reserved instance expires.
