Amazon EMR pricing is simple and predictable: you pay an hourly rate for every instance hour you use (so a 10-node cluster running for 10 hours costs the same as a 100-node cluster running for 1 hour). The hourly rate depends on the instance type used (e.g. standard, high cpu, high memory, high storage, etc).  Hourly prices range from $0.011/hour to $0.27/hour ($94/year to $2367/year).

The Amazon EMR price is in addition to the Amazon EC2 price (the price for the underlying servers). There are a variety of Amazon EC2 pricing options you can choose from, including On-Demand (shown below), 1 year & 3 year Reserved Instances, and Spot instances.

You can estimate your bill using the AWS Simple Monthly Calculator.

If you have large data processing requirements, you may be eligible for lower pricing. You can also prepay for unlimited EMR usage for 12 months.

You are charged from the time the cluster begins processing until it is terminated. Partial hours are rounded up.

The Amazon EC2 prices above are for On-Demand Instances. On-Demand Instances are the most expensive but give you the most flexibility. EC2 also offers Reserved Instances and Spot Instances.

  • Reserved Instances give you the option to make a low, one-time payment for each instance you want to reserve and in turn receive a significant discount on the hourly charge for that instance. There are three Reserved Instance types (Light, Medium, and Heavy Utilization Reserved Instances) that enable you to balance the amount you pay upfront with your effective hourly price.
  • Spot Instances enable you to bid for unused Amazon EC2 capacity. Instances are charged the Spot Price, which is set by Amazon EC2 and fluctuates periodically depending on the supply of and demand for Spot Instance capacity. To use Spot Instances, you specify the maximum price you are willing to pay per instance hour. If your maximum price bid exceeds the current Spot Price, your request is fulfilled and your instances will run until either you choose to terminate them or the Spot Price increases above your maximum price (whichever is sooner).

"Amazon Elastic MapReduce with Spot Instances has made it easy to prototype and surprisingly cost-effective to scale, decreasing our data processing costs by over 50%." - VP of Engineering at Fliptop

To view more information and current prices for Reserved Instances and Spot Instances, see the Amazon EC2 pricing page.

  • Amazon S3 is billed separately. (Many customers store their input and output data in S3; others store all of the data locally on HDFS.) Currently it costs $668 per month to store 10 TB of data in S3 with reduced redundancy. The more data you store, the lower the monthly price per GB.
  • Amazon SimpleDB is also billed separately. (Only applies if you enable debugging for your cluster)
  • AWS GovCloud (US) is an AWS Region designed to allow U.S. government agencies and contractors to move more sensitive workloads into the cloud by addressing their specific regulatory and compliance requirements. For pricing and more information on the AWS GovCloud (US) Region, please visit the AWS GovCloud (US) Pricing Page.
  • There is an additional charge for the MapR M5 and M7 distributions. See the MapR detail page for more information and current prices. There is no additional charge for MapR M3.
