Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand instance pricing. In addition, when Reserved Instances are assigned to a specific Availability Zone, they provide a capacity reservation, giving you additional confidence in your ability to launch instances when you need them.
Standard Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand instance pricing, and can be purchased for a 1-year or 3-year term. Customers have the flexibility to change the Availability Zone, the instance size, and networking type of their Standard Reserved Instances.
Purchase Convertible Reserved Instances if you need additional flexibility, such as the ability to use different instance families, operating systems, or tenancies over the Reserved Instance term. Convertible Reserved Instances provide you with a significant discount (up to 45%) compared to On-Demand and can be purchased for a 3-year term.
You can choose between three payment options when you purchase a Standard or Convertible Reserved Instance. With the All Upfront option, you pay for the entire Reserved Instance term with one upfront payment. This option provides you with the largest discount compared to On-Demand instance pricing. With the Partial Upfront option, you make a low upfront payment and are then charged a discounted hourly rate for the instance for the duration of the Reserved Instance term. The No Upfront option does not require any upfront payment and provides a discounted hourly rate for the duration of the term.
*This is the average monthly payment over the course of the Reserved Instance term. For each month, the actual monthly payment will equal the actual number of hours in that month multiplied by the hourly usage rate. The hourly usage rate is equivalent to the total average monthly payments over the term of the Reserved Instance divided by the total number of hours (based on a 365 day year) over the term of the Reserved Instance.
**Effective hourly pricing is shown to help you calculate the amount of money that a Reserved Instance will save you over On-Demand pricing. When you purchase a Reserved Instance, you are billed for every hour during the entire Reserved Instance term that you select, regardless of whether the instance is running or not. The effective hourly price shows the amortized hourly cost of the instance (this takes the total cost of the Reserved Instance over the entire term, including any upfront payment, and spreads it out over each hour of the Reserved Instance term).
If you purchase a large number of Amazon EC2 Reserved Instances in an AWS region, you will automatically receive discounts on your upfront fees and hourly fees for future purchases of Standard Reserved Instances in that AWS region. Reserved Instance tiers are determined based on the List Value (non-discounted total price) for the active Reserved Instances you have per AWS region. A complete list of the Reserved Instance tiers is shown below:
For example, as soon as you have aggregated active Reserved Instances with a List Value totaling more than $500,000 in a single AWS region, you will automatically receive a 5% discount on both upfront and hourly fees for all future Standard Reserved Instance purchases in that AWS region, and those discounts will continue to apply to new Standard Reserved Instances as long as you continue to qualify for the discount tier. For an in-depth example, please visit the EC2 Reserved Instances FAQ.
Please note that Reserved Instance purchases of Windows with SQL Server are not included in the computation of volume tier discounts. Also, due to the scale of Microsoft licensing fees, volume tier discounts are not available for Windows with SQL Server Reserved Instances. Reserved Instance Marketplace and Convertible Reserved Instance purchases do not qualify for the volume discount but the prorated remaining list value for these purchases will count towards your volume discount status.
Purchasing Reserved Instances on a recurring schedule lets you pay for compute capacity by the hour and obtain a capacity reservation ahead of time for only the time periods you will need it.
Pricing is set by Amazon EC2 and may change depending on the supply and demand for Scheduled Reserved Instance capacity and the time characteristics of your schedule. However, once you purchase a Scheduled Reserved Instance, the price you were given for that Scheduled Reserved Instance is the price you will pay for it.
The following table provides an indication of the regions and instance types available for purchase and an approximate price for each (prices change slightly from time to time). Prices during peak hours reflect a 5% discount off On-Demand usage charges; off-peak hours include an additional 5% discount off On-Demand usage charges. Operating System license charges, when applicable, are not discounted.
