Amazon Aurora is a modern relational database service. It offers unparalleled high performance and high availability at global scale with fully open-source MySQL- and PostgreSQL-compatible editions and a range of developer tools for building serverless and machine learning (ML)-driven applications.

Choose the Aurora pricing that is right for your business needs, with predictable, pay-as-you-go, On-Demand, or Reserved Instance pricing. Aurora charges for database instances, storage, and I/O based on database cluster configuration, along with any optional features you choose to enable.

Aurora cluster configuration NEW

With Aurora, you can configure your database clusters to run cost effectively, regardless of the scaling needs or evolving data access patterns of your applications. You have the flexibility to choose between the Amazon Aurora Standard and Amazon Aurora I/O-Optimized configuration options to best match the price-performance and price-predictability requirements of your unique workload characteristics. Your database instance, storage, and I/O charges will vary based on the option you choose. To learn more, visit Amazon Aurora storage and reliability.

Aurora Standard offers cost-effective pricing for the vast majority of applications running on Aurora with typical data access patterns and low to moderate I/O usage. With Aurora Standard, you pay for your database instances, storage, and pay-per-request I/O.

Aurora I/O-Optimized delivers improved price performance for I/O-intensive applications. If your I/O spend exceeds 25% of your total Aurora database spend, you can save up to 40% on costs for I/O-intensive workloads with Aurora I/O-Optimized. With Aurora I/O-Optimized, you only pay for your database instances and storage usage, and there are zero charges for read and write I/O operations. Aurora I/O-Optimized offers predictable pricing for all applications regardless of evolving data access patterns or I/O usage. Aurora I/O-Optimized eliminates variability in I/O spend.

Pricing by database instances

With Aurora, you can choose Amazon Aurora Serverless, which automatically starts up, shuts down, and scales capacity up or down based on your application's needs; you pay only for capacity consumed.

Alternatively, you can choose Provisioned On-Demand Instances and pay for your database per DB instance-hour consumed with no long-term commitments or upfront fees, or choose Provisioned Reserved Instances for additional savings.

Instance charges apply to both Aurora primary instances and Replicas. The charges will vary based on the database cluster configuration you choose to best match the price-performance and price-predictability needs of your application. All instances in a database cluster will either be charged the price for the Aurora Standard or Aurora I/O-Optimized configuration.

Select "Aurora MySQL-Compatible Edition" or "Aurora PostgreSQL-Compatible Edition" to view database instance pricing.

    • Serverless

    • Amazon Aurora Serverless is an on-demand, auto scaling configuration that automatically adjusts database capacity based on application needs. With Aurora Serverless, your database capacity automatically scales up or down to meet your application workload needs and shuts down during periods of inactivity, saving you money and administration time. Aurora Serverless measures database capacity in Aurora Capacity Units (ACUs) billed per second. 1 ACU has approximately 2 GiB of memory with corresponding CPU and networking, similar to that used in Aurora provisioned instances.

      Aurora Serverless v2

      Amazon Aurora Serverless v2 instantly scales databases to support hundreds of thousands of transactions per second and supports all features of Aurora, including Multi-AZ deployments, Read Replicas, and Global Database. In addition to gaining access to v2 features, most Aurora Serverless customers can lower costs by moving to v2 due to a lower starting capacity of 0.5 ACUs (compared to 2 ACUs in v1), capacity increments of as small as 0.5 ACUs (compared to doubling in v1), and up to 15x faster scale down in capacity compared to Amazon Aurora Serverless v1.

      You can choose to configure all the instances in your database cluster to use the Aurora Standard or Aurora I/O-Optimized configuration based on the price-performance and price-predictability needs of your application.

    • Provisioned On-Demand Instance

    • On-Demand Instances let you pay for your database by the hour with no long-term commitments or upfront fees.

      Pricing is per instance-hour consumed, from the time a database instance is launched until it is stopped or deleted. Partial instance-hours are billed in 1-second increments with a 10-minute minimum charge following a billable status change such as creating, starting, or modifying the database instance.

      You can choose to configure all the instances in your database cluster to use the Aurora Standard or Aurora I/O-Optimized configuration based on the price-performance and price-predictability needs of your application.

      Provisioned On-Demand Instance pricing for Aurora

      T4g and T3 CPU Credits

      Amazon RDS T4g and T3 DB instances run in Unlimited mode, which means that you will be charged if your average CPU utilization over a rolling 24-hour period exceeds the baseline of the instance. CPU Credits are charged at $0.09 per vCPU-Hour for Aurora Standard and $0.12 per vCPU-Hour for Aurora I/O-Optimized cluster configuration. The CPU Credit pricing is the same for all T4g and T3 instance sizes across all regions and is not covered by Reserved Instances.

    • Provisioned Reserved Instance

    • Reserved Instances are appropriate for steady-state database workloads and offer significant savings over On-Demand Instances. 1-year Reserved Instances provide discounts up to 45% and 3-year Reserved Instances provide discounts of up to 66% over On-Demand Instances. Reserved Instances provide flexibility across instance sizes and cluster configuration options.

      Your Reserved Instances discounted rate is automatically applied to usage of any size in the same instance family (such as T3 and R5) across Aurora Standard and Aurora I/O-Optimized configurations. You commit to the entire duration of the Reserved Instance term and pay a discounted hourly rate as shown in the following table.

      Although these rates apply to Aurora Standard, when using Reserved Instances with Aurora I/O-Optimized, Aurora automatically accounts for the price difference between these options for your usage. To fully utilize the benefits of your RI discounts with Aurora I/O-Optimized, you can purchase 30% additional RIs similar to your current RIs. See pricing example for more information. You will be billed for each hour of the term regardless of whether any usage has occurred.

      You purchase a Reserved Instance for each database instance you plan to use. You may designate database instances as Reserved Instances by calling the Purchasing API or selecting the Reserved Instance option in the AWS console. When you designate a database instance as a Reserved Instance, you must designate an AWS Region, instance type, and quantity for the applicable Reserved Instances. The Reserved Instances may only be used in the designated Region.

      Reserved Instance prices do not cover storage costs. Read and write I/O costs are only covered when your database cluster is configured to Aurora I/O-Optimized. In addition to being subject to Reserved Instance pricing, Reserved Instances are subject to all data transfer and other fees applicable under the AWS Customer Agreement or other agreement with AWS governing your use of AWS services. AWS may terminate the Reserved Instance pricing program at any time.

      Read the detailed Reserved Instance pricing example.

      Provisioned Reserved Instance pricing for Aurora

      * 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 or number of seconds in that month multiplied by the hourly usage rate divided by 3600, depending on the Aurora instance type you run. 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 helps you calculate the amount of money 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 you select, regardless of whether the instance is running. The effective hourly price shows the amortized hourly instance cost. 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.

Pricing by database storage and I/Os

With Aurora, you do not need to provision either storage or I/O operations in advance, and both scale automatically. The fault-tolerant distributed storage of Aurora automatically makes your data durable across three Availability Zones in a Region. You only pay for one copy of the data.

Aurora storage is billed in per GB-month increments at the rates shown in the following table for the Aurora Standard and Aurora I/O-Optimized configurations. With Aurora Standard, you pay for the storage and I/O operations that your Aurora database consumes. I/O charges may vary significantly depending on workload and database engine. To learn more about I/O operations, visit the Aurora FAQ, “Q: What are I/O operations in Aurora and how are they calculated?” With Aurora I/O-Optimized, you are not charged for read and write I/O operations.

Aurora Global Database costs

Amazon Aurora Global Database is designed for globally distributed applications, allowing a single Aurora database to span multiple Regions. It replicates your data with no impact on database performance, enables fast local reads with low latency in each Region, and provides disaster recovery from Region-wide outages.

With Aurora Global Database, you pay for replicated write I/O operations between the primary Region and each secondary Region. The number of replicated write I/O operations to each secondary Region is the same as the number of in-Region write I/O operations performed by the primary Region. You pay for replicated write I/O operations with both Aurora Standard and Aurora I/O-Optimized configuration options. Apart from replicated write I/Os, you pay for instances, storage, and I/O usage in the primary and secondary Regions based on the cluster configuration you choose, along with cross-Region data transfer, backup storage, and other billable Aurora features.

Read the detailed Aurora Global Database pricing example.

Backup storage costs

Backup storage for Aurora is the storage associated with your automated database backups and any customer-initiated database cluster snapshots.

You are not charged for the backup storage of up to 100% of the size of your database cluster. There is also no charge for database snapshots created within the backup retention period. For all other backups and snapshots (including those from deleted clusters), usage is metered per GB-month at the following rates:

Backtrack costs

Backtrack lets you quickly move an Aurora database to a prior point in time without needing to restore data from a backup. This lets you quickly recover from user errors, such as dropping the wrong table or deleting the wrong row. This feature is currently available for the MySQL-compatible edition of Aurora.

Specify how far in the past you want to be able to backtrack (for example, up to 24 hours). Aurora will retain logs, called change records, for the specified backtrack duration. You pay an hourly rate for storing change records.

Read the detailed backtrack pricing example.

Snapshot or cluster export costs

Snapshot export provides an automated method to export data within an Aurora snapshot to Amazon Simple Storage Service (Amazon S3) in Parquet format. Cluster export provides an automated method to export data from an Aurora database cluster to Amazon S3 in Parquet format. The Parquet format is up to 2x faster to unload and consumes up to 6x less storage in Amazon S3 compared to text formats. You can analyze the exported data using AWS services such as Amazon Athena, Amazon EMR, and Amazon SageMaker.

For all snapshots and cluster exports, usage is metered per gigabyte of snapshot data. Subsequent exports of data from the same snapshot are not incremental. Read the detailed snapshot or cluster export pricing example.

Additional charges apply for encrypting or decrypting data with AWS Key Management Service (AWS KMS). Find more about these charges on the AWS KMS pricing page. Charges also apply for storing exported data in Amazon S3 and for PUT requests made against your S3 bucket. Find more about these charges on the Amazon S3 pricing page.

Feature availability and support varies across specific versions of each database engine and across AWS Regions. For more information on version and Region availability of exporting DB cluster snapshot data to S3, see Exporting snapshot data to Amazon S3.

Amazon RDS Extended Support costs

Amazon RDS Extended Support allows you to continue use Aurora MySQL-Compatible and PostgreSQL-Compatible Edition major versions after the community end-of-life. During this time, AWS provides fixes for critical security issues and bugs through patch releases, giving you more time, up to three years, to upgrade to a new major version to help you meet your business requirements.

For provisioned instances on Amazon Aurora, RDS Extended Support is priced per vCPU per hour. For Aurora Serverless v2, RDS Extended Support is priced per Aurora Capacity Unit (ACU) per hour consumed by your database. RDS Extended Support pricing is also dependent on AWS Region and the calendar date. Aurora MySQL-Compatible Edition customers have at least a year to migrate to a standard support version after community end of life before RDS Extended Support charges begin. Refer to the Amazon Aurora documentation for calendar details.

    • Provisioned Instances

    • The RDS Extended Support price you are charged depends on the engine version, AWS Region, and the number of calendar years since standard support expired for that version. To learn more about when year 1 and 2 or year 3 pricing begins for a specific engine major version, go to the Amazon Aurora documentation.

RDS Extended Support pricing example

If you have an instance on Aurora PostgreSQL-Compatible 12, this version reaches end of standard support on February 28, 2025. If you deploy in US East (Ohio), you will be charged $0.100 per vCPU-hr between March 1, 2025 to February 28, 2027. Starting March 1, 2027, you will be charged $0.200 per vCPU-hr.

Data transfer costs

The pricing below is based on data transferred “in” and “out” of Aurora.

  • As part of the AWS Free Tier, AWS customers receive 100 GB of free data transferred out to the internet for free each month, aggregated across all AWS services and Regions (except China (Beijing), China (Ningxia), and GovCloud (US)).
  • Data transferred between Aurora and Amazon Elastic Compute Cloud (Amazon EC2) instances in the same Availability Zone is free.
  • Data transferred between Availability Zones for DB cluster replication is free.  
  • For data transferred between an Amazon EC2 instance and Aurora DB instance in different Availability Zones of the same Region, Amazon EC2 Regional Data Transfer charges apply.

WS customers receive 100GB of data transfer out to the internet free each month, aggregated across all AWS Services and Regions (except China and GovCloud). The 100 GB free tier for data transfer out to the internet is global and does not apply separately or individually to AWS Regions.

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

Aurora pricing examples

The following examples demonstrate how Aurora costs are calculated for resources and features available for Aurora.

Examples using Aurora Serverless:

Consider a workload that needs 5 ACUs and runs for 30 minutes. We want to calculate the compute costs of running this workload on Aurora Serverless v1 and v2 with the database cluster configured as Aurora Standard and Aurora I/O-Optimized in US East (N. Virginia).

With Aurora Serverless v2, the minimum database capacity you can set is 0.5 ACUs. The database scales instantly from 0.5 ACUs to 5 ACUs, runs for 30 minutes, and scales down to the minimum capacity of 0.5 ACUs. Since v2 scales down up to 15x faster, the database goes from 5 ACUs to 0.5 ACUs in approximately 3 minutes. Therefore, the following is the compute cost for running this workload.

Example 1: Aurora Serverless v2 pricing with Aurora Standard

Usage Calculation  Cost

Scale from 0.5 ACUs to 5 ACUs instantly

    
Run at 5 ACUs for 30 minutes 5 ACUs * $0.12 per ACU-hour * 30/60 hour $0.30
Scale down from 5 ACUs to 0.5 ACUs in 3 minutes 5 ACUs * $0.12 per ACU-hour * 3/60 hour $0.03

Compute cost with Aurora Serverless v2 (Aurora Standard)

   $0.33

Example 2: Aurora Serverless v2 pricing with Aurora I/O-Optimized

Usage Calculation  Cost

Scale from 0.5 ACUs to 5 ACUs instantly

    
Run at 5 ACUs for 30 minutes 5 ACUs * $0.156 per ACU-hour * 30/60 hour $0.39
Scale down from 5 ACUs to 0.5 ACUs in 3 minutes 5 ACUs * $0.156 per ACU-hour * 3/60 hour $0.04

Compute cost with Aurora Serverless v2 (Aurora I/O-Optimized)

With Aurora Serverless v1, the minimum capacity you can set is 1 ACU. The amount of time Aurora Serverless v1 takes to scale capacity depends on the workload. Assuming that Aurora Serverless v1 is able to double capacity every minute, the database would scale to 8 ACUs in 3 minutes. The database then runs for 30 minutes at 8 ACUs. Finally, the database scales down from 8 ACUs to 1 ACU by halving capacity every 15 minutes. Therefore, the following is the compute cost for running this workload.

Examples using database storage and I/O operations:

Let’s assume you have an Aurora database and you start with a 1,000 GB database at the beginning of the month (30-day period) that is growing 2% or 20 GB daily. Let’s also assume the same database reads 350 data pages from storage per second to satisfy the queries running on it. Finally, let’s assume your application makes changes to the database affecting an average of 100 data pages per second. We want to calculate the storage and I/O cost of running this workload with Aurora Standard and Aurora I/O-Optimized storage in US East (N. Virginia).
