🔍 What is AWS RDS?

Amazon RDS (Relational Database Service) is a fully managed database service that supports multiple database engines, including:

  • Amazon Aurora
  • MySQL
  • MariaDB
  • PostgreSQL
  • Oracle
  • Microsoft SQL Server

It handles routine database tasks such as backups, patch management, scalability, and performance tuning, enabling businesses to focus more on application development.

🧮 What is the AWS RDS Pricing Calculator?

The AWS RDS Pricing Calculator is a cost estimation tool designed to help users project their monthly or annual AWS RDS expenses based on specific configurations. It allows you to input variables like:

  • Instance type (e.g., db.t3.medium, db.m5.large)
  • Database engine (e.g., PostgreSQL, MySQL)
  • Region (e.g., US East, Europe West)
  • Storage type and size
  • Backup storage
  • IOPS (input/output operations per second)
  • Licensing model (for SQL Server/Oracle)

By adjusting these options, you can accurately forecast your cloud database spending.

🛠️ How to Use the AWS RDS Pricing Calculator

Using the AWS RDS Pricing Calculator is straightforward. Here’s a step-by-step guide:

  1. Select Database Engine
    Choose between Aurora, PostgreSQL, MySQL, Oracle, SQL Server, or MariaDB.
  2. Select Instance Type
    Choose from a wide array of instance families and sizes based on your workload needs.
  3. Choose Deployment Option
    Options include:
    • Single-AZ or Multi-AZ
    • On-Demand or Reserved Instances
  4. Enter Storage Requirements
    Define:
    • Storage type (General Purpose SSD, Provisioned IOPS SSD, or Magnetic)
    • Allocated storage (in GB)
    • Provisioned IOPS (if applicable)
  5. Backup Storage
    Add the volume of backup storage beyond the free allocated amount (typically 100% of DB storage).
  6. License Model
    Depending on the engine, choose between License Included or Bring Your Own License (BYOL).
  7. Region
    Costs vary by region, so ensure you select your deployment region.
  8. Review Estimated Monthly Cost
    The tool will output a detailed breakdown of your expected monthly and yearly charges.

🧾 AWS RDS Pricing Formula

While pricing varies by region, instance type, and other variables, the general formula for AWS RDS costs includes:

pgsqlCopyEditTotal Cost = Instance Cost + Storage Cost + IOPS Cost + Backup Cost + Data Transfer Cost + Licensing Cost (if any)

Breakdown:

  1. Instance Cost = Hourly Rate × Number of Hours (usually 730 per month)
  2. Storage Cost = Allocated GB × $ per GB (varies by type)
  3. Provisioned IOPS Cost = IOPS × $ per IOPS-month
  4. Backup Storage Cost = Additional GB × $ per GB
  5. Data Transfer Cost = Outbound GB × $ per GB (inbound is usually free)
  6. Licensing Cost = Depends on engine and model

📊 Example: Estimating a PostgreSQL Deployment

Let’s walk through an example:

Specifications:

  • Engine: PostgreSQL
  • Instance: db.m5.large (2 vCPU, 8 GB RAM)
  • Region: US East (N. Virginia)
  • Storage: 100 GB General Purpose (SSD)
  • Backup: 50 GB additional
  • Multi-AZ deployment: Yes

Estimated Monthly Costs:

  • Instance Cost: $0.096/hour × 730 hours = $70.08
  • Storage Cost: 100 GB × $0.10 = $10.00
  • Backup Cost: 50 GB × $0.095 = $4.75
  • Multi-AZ Replication: ~100% of instance cost = $70.08
  • Total Monthly Estimate: ≈ $154.91

Inbound data transfer is free, but outbound transfer is charged based on volume and region.

6. What are Reserved Instances?

Reserved Instances offer significant discounts for long-term commitments (1 or 3 years).

7. Does storage type affect cost?

Yes, gp3, io1, and magnetic have different pricing models.

8. What is Multi-AZ deployment?

It replicates data across availability zones for high availability and incurs double instance cost.

9. Are backups free?

Backups equal to your allocated storage are free. Additional backup incurs charges.

10. What if I use BYOL for Oracle or SQL Server?

You won’t be charged for licensing but must have valid licenses according to AWS guidelines.
