 Save on your Microsoft Sentinel costs when you buy a pre-purchase plan. Pre-purchase plans are commit units (CUs) bought at discounted tiers in your purchasing currency for a specific product. The more you buy, the greater the discount. Purchased CUs pay down qualifying costs in US dollars (USD). So, if Microsoft Sentinel generates a retail cost of $100, then 100 Sentinel CUs (SCUs) are consumed. 
 
-Any eligible Microsoft Sentinel retail costs automatically deduct first from your SCUs over the course of its one year term or until they are depleted. Your pre-purchase plan SCUs start paying for your Microsoft Sentinel workspace costs without needing to redeploy or reassign the plan, and by default automatically renew to ensure you continue saving.

 A $100,000 USD pre-purchase plan covers five months of that commitment tier but is valid for paying Microsoft Sentinel costs for 12 months. That pre-purchase plan is bought at a 22% discount for $78,000 USD. 
 
-The savings for the commitment tier and the pre-purchase plan combine. The original pay-as-you-go price for five months of 200 GB/day ingestion and analysis costs is about $160,000 USD. With an accurate commitment tier and a pre-purchase plan, the cost is reduced to $78,000 USD for a combined savings of over 51%.

With an accurate commitment tier and a pre-purchase plan, the cost is reduced to $78,000 USD for a combined savings of over 51%. Since the example plan is depleted after just 5 months, the best way to ensure continued savings is to purchase more SCUs with another plan.
