 In Cost analysis, you view costs with a metric. They include Actual cost and Amortized cost. Each metric affects how data is shown for your benefit charges.
 
-**Actual cost** - Shows the purchase as it appears on your bill. For example, if you bought a one-year reservation for $1200 in January 2022 and you paid for the entire purchase cost upfront, then cost analysis shows a $1200 cost in the month of January for the reservation. It doesn't show a reservation cost for other months of the year. However, if you're paying the reservation on a monthly basis, then you see this recurring cost on the monthly anniversary date. If you group your actual costs by VM, then a VM that received the reservation benefit for a given month would have zero cost for the month.

You will see the same monthly charge on your invoice as well.
 
 **Amortized cost** - Shows a reservation purchase split as an amortized cost over the duration of the reservation term. With the same previous example, cost analysis shows a different amount for each month depending on the number of days in the month. If you group costs by VM in this example, you'd see cost attributed to each VM that received the reservation benefit. However, _unused reservation_ costs aren't attributed to the subscription used to buy the reservation because the unused portion isn't attributable to any specific resource or subscription. Similarly, unused saving plan costs aren't attributed to the subscription used to buy the saving plan.
