How does Amazon EC2 Spot Instances pricing work?

With Spot Instances, you pay the Spot price that's in effect for the time period your instances are running. Spot Instance prices are set by Amazon EC2 and adjust gradually based on long-term trends in supply and demand for Spot Instance capacity. To learn more about pricing, visit the Spot Instance history page. The following table displays the Spot price for each region and instance type (updated every 5 minutes).

Spot Instances are available at a discount of up to 90% off compared to On-Demand pricing. To compare the current Spot prices against standard On-Demand rates, visit the Spot Instance Advisor.

Note that you can now run Linux based RHEL and SUSE AMIs on Spot Instances. Learn more.

Spot Instance Prices

  • Spot Instances

  • Note: T4g and T3 instances launch as unlimited by default. If you launch T4g or T3 Spot Instances as unlimited and plan to use them immediately and for a short duration, with no idle time for accruing CPU credits, you will incur charges for surplus credits. If the average CPU usage over a 24-hour period exceeds the baseline, you will also incur charges for surplus credits. We recommend that you launch your T4g or T3 Spot Instances in standard mode to avoid paying higher costs. For more information, see Surplus Credits Can Incur Charges and Spot Instance limits.

    The prices displayed below are the lowest prices per instance type in the region. For more information on Spot Instances pricing and to see the current price for each instance type and Availability Zone, please refer to Spot Instance pricing history in the EC2 User Guide.

    Notice: Red Hat has made an update to their cloud pricing model for Red Hat Enterprise Linux (RHEL). On July 1, 2024 pricing for EC2 RHEL changed to a per-vCPU-hour based pricing model. Learn about the new prices in the RHEL on AWS Pricing page.
