Database Cost Optimization Calculator

Model Amazon RDS for PostgreSQL in us-east-1: explicit Single-AZ / one-standby Multi-AZ compute, storage, gp3 performance, io2 IOPS, and chargeable backup above AWS's regional free allocation. Multi-AZ DB Cluster is out of scope. Published-list estimate only. The math runs in your browser — your numbers never leave this page.

Assumptions

Computed on your device. No accounts, no bill upload, nothing sent to a server or any vendor.

Price review required

Budget for monitoring alongside infrastructure

Monitoring is a separate line item. Use the Datadog pricing calculator to model log, metric, trace, RUM and synthetic-check usage before comparing monitoring plans. Published-list scenarios are not an invoice or vendor quote.

Decision guidance

Database cost and resilience decisions this calculator can test

This database model covers representative RDS and managed-Postgres instance, storage, provisioned IOPS, backup, replica, Multi-AZ, and reserved-capacity costs. It distinguishes removable waste from resilience or recovery requirements that must remain.

Questions it answers

  • Are provisioned IOPS separately billed for the selected storage type, and how much headroom must remain above measured use?
  • Which read replicas are removable after required HA and read-scaling capacity is protected?
  • Does disabling Multi-AZ remove waste, or does it simply remove required availability and durability?

When it returns zero or refuses a claim

  • IOPS reduction returns zero on storage where IOPS are bundled, and separately billed IOPS cannot be reduced below measured use plus headroom.
  • Replica removal is capped at the count above the stated HA or read-scaling requirement.
  • Disabling required Multi-AZ returns zero because resilience is not sold as savings; reserved coverage also warns when rightsizing has not happened first.

Verify against your invoice

  • Match instance class, running hours, deployment mode, replicas, storage GB, IOPS, and backup GB to database invoice lines.
  • Document the required replica count, Multi-AZ requirement, backup-retention floor, and recovery objectives with the service owner.
  • Compare reserved coverage only after instance rightsizing and non-required replicas have been evaluated.

The calculator remains a published-list scenario, not a quote or your actual bill. Use the source links and invoice lines below before acting.
