-You can save on your Azure Databricks unit (DBU) costs when you pre-purchase Azure Databricks commit units (DBCU) for one or three years. You can use the pre-purchased DBCUs at any time during the purchase term. Unlike VMs, the pre-purchased units don't expire on an hourly basis and you use them at any time during the term of the purchase.

 Before you buy, calculate the total DBU quantity consumed for different workloads and tiers. Use the preceding ratios to normalize to DBCU and then run a projection of total usage over next one or three years.
