A method for storage allocation analysis is provided. Storage usage is measured for a file system to determine a burn rate. A date is calculated when the storage usage is projected to exceed allocated storage for the file system based on the burn rate. Whether the calculated date is less than an allocation period from the current date is determined. An amount of additional storage is requested in response to determining that the calculated date is less than the allocation period from the current date. The amount of additional storage is based on projecting the burn rate for at least one storage procurement cycle.
