 ### Combined policies
 
-Although user-based throttling policies provide more control than subscription-based throttling policies, there is still value combining both capabilities. For monetized APIs, throttling by product subscription key ([Limit call rate by subscription](rate-limit-policy.md) and [Set usage quota by subscription](quota-policy.md)) is a great way to implement fees that are based on usage levels. The finer-grained control of being able to throttle by user is complementary and prevents one user's behavior from degrading the experience of another.
