Amazon RDS pricing

Customers have a number of deployment options for Amazon RDS including on-premises environments using Amazon RDS on Outposts, using Amazon RDS Custom for privileged access to underlying database for applications like Oracle E-Business Suite, or running Amazon RDS Proxy to make applications more scalable, resilient, and secure. 

Amazon RDS Extended Support allows you to continue use MySQL and PostgreSQL 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 for MySQL, and RDS for PostgreSQL, 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 the calendar date. 

To learn more about RDS Extended Support costs, see the Aurora, RDS for MySQL, and/or RDS for PostgreSQL pricing pages.

• Data transferred between Amazon RDS and Amazon EC2 instances in the same Availability Zone

Free. 

• Data transferred between Availability Zones for replication of Multi-AZ deployments 

Free.      

• Amazon RDS DB instances outside VPC
  

Data transferred between an EC2 instance and Amazon RDS DB instance in different Availability Zones of the same Region have no data transfer charge for traffic in or out of the Amazon RDS DB instance. You are only charged for the data transfer in or out of the EC2 instance and standard EC2 Regional Data Transfer charges apply ($.01 per GB in/out).

• Amazon RDS DB instances inside VPC

For data transferred between an EC2 instance and an Amazon RDS DB instance in different Availability Zones of the same Region, EC2 Regional Data Transfer charges apply on both sides of transfer. There will be no data transfer charge for traffic in or out of the Amazon RDS DB instance.

• DB snapshot copies across Regions

DB snapshot copy is charged for the data transferred to copy the snapshot data across Regions. When the snapshot is copied, standard Amazon RDS database snapshot charges will apply to store it in the destination Region.

• Cross-Region automated backups

Cross-Region automated backups are charged for the data transferred to copy the Amazon RDS DB snapshot and DB transaction logs across Regions. When the snapshot is copied, standard database snapshot charges will apply to store it in the destination Region. There is no additional charge for storage of the DB transaction logs.

• Amazon RDS Free Tier

As part of AWS Free Tier, AWS customers receive 100 GB of free data transfer out to the internet free each month, aggregated across all AWS Services and Regions (except China and GovCloud).

• Data transfer across other AWS services

Rate tiers take into account your aggregate data transfer out usage across EC2, Amazon EBS, Amazon S3, Amazon Glacier, Amazon RDS, Amazon SimpleDB, Amazon SQS, Amazon SNS, AWS Storage Gateway, Amazon DynamoDB, and Amazon VPC.

You will incur standard public IPv4 address charges associated with a resource launched in an Amazon VPC. Please read public IPv4 address pricing information for additional details.

Amazon RDS is free to try. You only pay for what you use with no minimum or set up fees. Amazon RDS costs will vary based on customer needs. To help estimate costs and view your options, use the free AWS Pricing Calculator.

New AWS accounts receive 12 months of AWS Free Tier access. Please see the AWS Free Tier FAQs for more information.

You are billed at standard Amazon RDS prices for instance hours beyond what the Amazon RDS Free Tier provides.

Monthly costs are based on location or database engine of interest as well as the following components:

• DB instance hours – Based on the type (e.g. db.t3.micro, db.m4.large) of the DB instance consumed. Following a billable status change, such as creating, starting, or modifying your DB instance type, you will be billed based on partial DB instance hours. Partial DB instance hours consumed are billed in one-second increments with a 10-minute minimum. For additional details, read our what's new announcement.
• Storage (per GB per month) – Storage capacity you have provisioned to your DB instance. If you scale your provisioned storage capacity within the month, your bill will be pro-rated.
• I/O requests per month – Total number of storage I/O requests (for Amazon RDS magnetic storage and Amazon Aurora only).
• Provisioned IOPS per month – Provisioned IOPS rate, regardless of IOPS consumed (for Amazon RDS Provisioned IOPS storage only).
• Backup Storage – The storage associated with your automated database backups and any customer-initiated database snapshots. Increasing your backup retention period or taking additional database snapshots increases the backup storage consumed by your database.
• Data transfer – Internet data transfer in and out of your DB instance.

Calculate what your monthly costs would be with the AWS Pricing Calculator.

Billing commences for a DB instance as soon as the DB instance is available and is billed for each hour it is running in an available state. Billing continues until the DB instance terminates, which would occur when upon deletion or in the event of an instance failure. Partial DB instance hours consumed are billed in one-second increments with a 10-minute minimum charge (following a billable status change, such as creating, starting, or modifying the DB instance type).

To stop all Amazon RDS related charges for an account, you need to delete all your Amazon RDS DB instances and snapshots. By only stopping an Amazon RDS DB instance, you stop billing for additional instance hours, but you will still incur storage costs.

While your database instance is stopped, you are charged for provisioned storage (including Provisioned IOPS) and backup storage (including manual snapshots and automated backups within your specified retention window), but not for DB instance hours.

There are multiple ways to reduce your Amazon RDS costs, including rightsizing your databases for your needs. With features like Amazon Aurora Serverless v2 and auto-scaling, you do not need to over-provision to ensure high availability. For additional cost savings, you can opt for Reserved Instances, which lets you reserve a database instance for a one- or three- year term at a significant discount compared to On-Demand Instance pricing.

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

You can purchase a Reserved Instance in the Reserved Instance section of the AWS Management Console for Amazon RDS. Alternatively, you can use the Amazon RDS API or the AWS Command Line Interface to list the reservations available for purchase and then purchase a DB instance reservation.

Once you have made a reserved purchase, using a Reserved Instance is no different than an on-demand DB instance. Launch a DB instance using the same instance type, engine, and region for which you made the reservation. As long as your reservation purchase is active, Amazon RDS will apply the reduced hourly rate for which you are eligible to the new DB instance.

You can purchase up to 40 Reserved Instances. If you wish to run more than 40 DB instances, please complete the Amazon RDS DB Instance request form.

The Amazon RDS operations for creating, modifying, and deleting DB instances do not distinguish between On-Demand and Reserved Instances (RIs). Our system will automatically apply your reservation(s) such that all eligible DB instances are charged at the lower hourly reserved DB instance rate.

When you purchase an RI under the All-Upfront payment option, you pay for the entire term of the RI in one upfront payment. You can also choose to pay nothing upfront by choosing the No Upfront option. The entire value of the No Upfront RI is spread across every hour in the term and you will be billed for every hour in the term, regardless of usage. The Partial Upfront payment option is a hybrid of the All Upfront and No Upfront options. You make a small upfront payment, and you are billed a low hourly rate for every hour in the term regardless of usage.
