Sources & methodology

Published inputs make comparisons repeatable. They do not predict how fast your workload will run.

The current catalog has 127 documented fixed instance types, captured 2026-11-12 UTC. The calculator’s Sources panel and exported scenarios retain more detailed source information.

Calculation boundary

The hourly estimate adds the driver and each worker’s EC2 charge and applicable Databricks charge. A public DBU quantity is multiplied by its unit price; an engine-specific direct rate is not multiplied again. Missing prices remain unknown.

Resource totals are host specifications, not performance scores. Instance documentation does not prove workspace, runtime, policy or AZ eligibility. The published estimate excludes separate storage and network charges, tax and contract discounts.
