 # What are Azure Reservations?
 
 Azure Reservations help you save money by committing to one-year or three-years plans for virtual machines, Azure Blob storage or Azure Data Lake Storage Gen2, SQL Database compute capacity, Azure Disk Storage, Azure Cosmos DB throughput, or other Azure resources. Committing allows you to get a discount on the resources you use. Reservations can significantly reduce your resource costs up to 72% on pay-as-you-go prices. Reservations provide a billing discount and don't affect the runtime state of your resources.
 
-You can pay for a reservation up front or monthly. The total cost of up-front and monthly reservations is the same and you don't pay any extra fees when you choose to pay monthly. Monthly payment is available for Azure reservations, not third party products.

 ## When the reservation term expires
 
-At the end of the reservation term, the billing discount expires, and the resources are billed at the pay-as-you go price. By default, the reservations are not set to renew automatically. You can choose to enable automatic renewal of a reservation by selecting the option in the renewal settings. With automatic renewal, a replacement reservation will be purchased upon expiry of the existing reservation. By default, the replacement reservation has the same attributes as the expiring reservation, optionally you change the billing frequency, term or quantity in the renewal settings. Any user with owner access on the reservation and the subscription used for billing can setup renewal.
