 # Optimize Azure Synapse Analytics costs with a Pre-Purchase Plan
 
 You can save on your Azure Synapse Analytics costs when you prepurchase Azure Synapse commit units (SCU) for one year. You can use the prepurchased SCUs at any time during the purchase term. Unlike VMs, the prepurchased units don't expire on an hourly basis and you use them at any time during the term of the purchase.
 
-Any Azure Synapse Analytics use deducts from the prepurchased SCUs automatically. You don't need to redeploy or assign a Pre-Purchased Plan to your Azure Synapse Analytics workspaces to get the prepurchase discounts.

 ## Determine the right size to buy
 
 A synapse prepurchase applies to all Synapse workloads and tiers. You can think of the Pre-Purchase Plan as a pool of prepaid Synapse commit units. Usage is deducted from the pool, regardless of the workload or tier. Integrated services such as VMs for SHIR, Azure Storage accounts, and networking components are charged separately.
 
+There’s no ratio on which the SCUs are applied. SCUs are equivalent to the purchase currency value and are deducted at retail prices. Like other reservations, the benefit of a pre-purchase plan is discounted pricing by committing to a purchase term. The more you buy, the larger the discount you receive.
+
+For example, if you want to use your SCUs for Data Warehousing – Dedicated SQL pool in West US 2, and you consume 1 hour of SQL Dedicated Pool DWU100 that has a retail price of $1.20, then 1.2 SCUs are consumed.
