Who This Tool Is For

DBAs, backend leads, and FinOps partners budgeting PostgreSQL, MySQL, or MariaDB on RDS. Teams debating Multi-AZ, gp3 sizing, or io1 for latency-sensitive OLTP.

Why We Built This Tool

RDS bills split across instance hours, storage GB, and IOPS — Multi-AZ doubles compute and provisioned storage. We built this from the us-east-1 rate card we use in database cost reviews.

What Problem It Solves

  • HA cost delta. Single-AZ vs Multi-AZ with storage doubling.
  • Engine toggle. PostgreSQL, MySQL, and MariaDB rate cards.
  • gp3 IOPS & throughput. Real overage rates above baseline — not placeholders.
  • RI discounts. Approximate 1-yr / 3-yr commitment multipliers.

Frequently Asked Questions

Where do these prices come from?

RDS On-Demand us-east-1 instance and storage list prices as of July 2026. Multi-AZ doubles instance hourly and provisioned storage. RI discounts are approximate No Upfront multipliers (~35% / ~55%), not exact Reserved Instance rate cards.

Are backups included?

Automated backup storage up to DB size is free; backup storage beyond provisioned DB size bills at S3 rates — not modeled here.

How does gp3 IOPS billing work?

gp3 includes 3,000 IOPS (12,000 for volumes ≥400 GB) and 125 MB/s. Extra IOPS bill at $0.02/IOPS-month and extra throughput at $0.04/MB/s-month. io1 bills all provisioned IOPS at $0.10/IOPS-month.

What about Aurora?

This tool targets RDS provisioned instances. For Aurora ACU/I/O pricing use our Aurora calculator and RDS vs Aurora comparison.

Licensing?

PostgreSQL, MySQL, and MariaDB are open-source on RDS — no separate license line. Oracle/SQL Server licensing is different and not modeled here.

How accurate is this estimate?

Compute and storage arithmetic matches published rates for listed instances. Real bills add Performance Insights, Proxy, Extended Support, and data transfer.
