The price for a Dedicated Host varies by instance family, region, and payment option. Regardless of the quantity or the size of instances that you choose to launch on a particular Dedicated Host you pay hourly for each active Dedicated Host, and you are not billed for instance usage.

When you allocate a Dedicated Host host for use, you must choose an instance type configuration for the host. This selection will define the number of sockets and physical cores per host, the type of instance you can run on the host, and the number of instances that you can run on each host.

After you have allocated a Dedicated Host, you will pay On-Demand unless you have a Dedicated Host Reservation. A Dedicated Host Reservation provides you with a discount of up to 70% compared to On-Demand pricing.

A Dedicated Host is configured to support one instance type at a time. For example, if you allocate a c3.xlarge Dedicated Host, you can use a Dedicated Host with two sockets and 20 physical cores configured to support up to 8 c3.xlarge instances. Refer to the table below for Dedicated Host instance configurations. For more information on instances, visit EC2 Instance Types.

When you pay On-Demand for Dedicated Hosts, you pay for each hour that the Dedicated Host is active in your account (or allocated). You can terminate billing for any particular On-Demand Dedicated Host by releasing it. On-Demand gives you the flexibility to scale up or down without long-term commitments. To learn more about how to allocate or release a Dedicated Host, visit Dedicated Hosts Getting Started.


Except as otherwise noted, our prices are exclusive of applicable taxes and duties, including VAT and applicable sales tax. For customers with a Japanese billing address, use of AWS is subject to Japanese Consumption Tax. Learn more.

Reservations can provide up to a 70% discount compared to the On-Demand price. Visit the Dedicated Host documentation to learn about how to purchase a Dedicated Host Reservation through customer support or your account manager. Console and API support for Dedicated Host Reservation purchases is coming soon.

You can choose between three Dedicated Host Reservation payment options. With the All Upfront option, you pay for the entire Dedicated Host Reservation with one upfront payment. This option provides you with the largest discount compared to On-Demand pricing. With the Partial Upfront option, you make a low upfront payment and are then charged a discounted hourly rate for the Dedicated Host for the duration of the reservation. The No Upfront option does not require an 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 Dedicated Host Reservation 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 divided by the total number of hours (based on a 365 day year) over the term.

**Effective hourly pricing is shown to help you calculate the amount of money that a Dedicated Host Reservation will save you over On-Demand pricing. When you purchase a Dedicated Host Reservation, you are billed for every hour during the entire term that you select, regardless of whether the instances are running or not. The effective hourly price shows the amortized hourly cost of the Dedicated Host Reservation (this takes the total cost of the Dedicated Host Reservation over the entire term, including any upfront payment, and spreads it out over each hour of the term). 

Should I consider a purchase of a Dedicated Host Reservation a capital or operational expense?

AWS does not provide accounting advice and we recommend that you ask your accountant to answer this question. We also recommend that you review the definition of the EC2 Dedicated Host before making an operational expense vs capital expense judgment on a purchase. Please visit this page for a detailed FAQ on this topic.
