Amazon RDS Proxy pricing

RDS Proxy is priced based on the capacity of underlying instances. For provisioned instances on Amazon Aurora, Amazon RDS for PostgreSQL, Amazon RDS for MySQL, Amazon RDS for MariaDB, and Amazon RDS for SQL Server, RDS Proxy is priced per vCPU per hour. For Amazon Aurora Serverless, RDS Proxy is priced per Aurora Capacity Unit (ACU) per hour consumed by your database.

Partial hours are billed in 1-second increments with a 10-minute minimum charge following a billable status change such as creating, starting, or modifying.

There are no additional charges associated with the default endpoint you get when you create an RDS Proxy. You can also add read-only or read-write proxy endpoints, each with their own VPC settings. Adding a RDS Proxy endpoint provisions an AWS PrivateLink interface endpoint, which incurs additional charges as described on the PrivateLink pricing page.
