Embodiments relate to systems and methods for aggregating marginal subscription offsets in a set of multiple host clouds. A set of aggregate usage history data can record consumption of processor, memory, operating system, or other resources subscribed to by a user across multiple host clouds. An entitlement engine can analyze the aggregate usage history data to identify a short-term subscription margin for one or more subscribed resources, such as processor throughput, operating system instances, or other resources reflecting the under or over-consumption of a cloud resource against subscription limits on an hourly or other basis across multiple clouds. The entitlement engine can track the short-term subscription margin for one or multiple resources each hour of a day, and/or over other intervals, and determine the positive or negative subscription offset cost for each interval. The offsets can be combined to generate a net or aggregate subscription offset cost, or to provide other subscription adjustments.
