Estimate Oracle Autonomous Database costs for ATP, ADW, and AJD with ECPU and storage pricing.
Last verified: May 2026
Output will appear here...The estimator calculates ADB monthly cost across configurations: base OCPU × per-OCPU-hour rate (varies by Edition: Standard, Enterprise, Enterprise Performance), storage TB × per-TB-month rate, BYOL discount if applicable, optional auto-scaling cost (estimated based on expected average vs peak utilization), and backup storage. It compares Serverless vs Dedicated infrastructure pricing for high-volume scenarios where Dedicated becomes more cost-effective.
Oracle Autonomous Database (ADB) on OCI uses an OCPU-based pricing model with options for dedicated infrastructure, serverless, and Autonomous Database Free Tier. Costs depend on the OCPU count, storage volume, edition (Standard vs. Enterprise), workload type (OLTP, Data Warehouse, JSON, APEX), and whether auto-scaling is enabled. The Autonomous Database Cost Estimator calculates monthly expenses based on your configuration choices, including the impact of auto-scaling (up to 3x base OCPU), backup storage, and the cost difference between License Included and Bring Your Own License (BYOL) models.
Your team is migrating an on-prem Oracle Database to OCI Autonomous. Existing license: Oracle EE with Active Data Guard. Workload: 8 OCPU steady, 24 OCPU month-end peaks. The estimator compares: License Included at $4,800/month (no auto-scaling) vs $1,920/month (with auto-scaling matching actual usage); BYOL with auto-scaling at $960/month. With the existing license, BYOL+auto-scaling saves $3,840/month vs the naive License Included approach. Annual savings: $46K.
Always Free Autonomous Database is uniquely generous — 1 OCPU + 20 GB perpetual free. No other cloud provider offers a free managed database with this longevity. Perfect for dev, learning, hobby projects, or as a CI/CD test database. The 7-day idle stop is the only catch — set up a periodic ping job if you need it always-on.
BYOL (Bring Your Own License) cuts ADB costs by ~50% if you have existing Oracle Database licenses with active support. Many teams forget about old Oracle licenses they're already paying for and pay full ADB License Included pricing — verify your existing entitlements before provisioning.
Auto-scaling can burst to 3x base OCPU but you only pay for actual usage. The trick: set base OCPU low (matching steady-state) and let auto-scaling handle peaks. A 2-OCPU base with auto-scaling absorbs 6-OCPU peaks at fraction of provisioning 6 OCPUs always-on.
Serverless (shared infrastructure) runs on Oracle-managed Exadata infrastructure shared with other tenants, with pay-per-OCPU-hour pricing and automatic scaling. Dedicated runs on customer-exclusive Exadata infrastructure, providing complete isolation, custom maintenance schedules, and the ability to host multiple databases on the same infrastructure. Dedicated is priced per Exadata infrastructure unit and is cost-effective when running many Autonomous Databases at scale.
When auto-scaling is enabled, the database can use up to 3x the base OCPU count during demand spikes. You pay for the actual OCPUs consumed per hour, not the peak capacity. For example, an 8 OCPU base can burst to 24 OCPUs, but if it only uses 12 OCPUs for one hour, you pay for 12 OCPU-hours. Storage auto-scaling is separate and grows the allocated storage automatically up to the configured limit.
OCI offers an Always Free tier that includes one Autonomous Database with 1 OCPU and 20 GB of storage at no cost, with no time limit. The database automatically stops after 7 days of inactivity and is reclaimed after 90 days if not restarted. It includes all enterprise features but does not support auto-scaling or dedicated infrastructure. It is ideal for development, learning, and prototyping.
