+# 💸 User-based Rate Limiting
+
+LiteLLM exposes the `BudgetManager` class to help with user-based rate limiting. 
+
+## quick start
+
+```python
+from litellm import BudgetManager, completion 
+
+budget_manager = BudgetManager(project_name="test_project")
+
+user = "1234"
+
+# create a budget for a user
+budget_manager.create_budget(total_budget=10, user=user)
+
+# check if a given call can be made
+if budget_manager.get_current_cost(user=user) <= budget_manager.get_total_budget(user):
+    response = completion(model="gpt-3.5-turbo", messages=[{"role": "user", "content": "Hey, how's it going?"}])
+    budget_manager.update_cost(completion_obj=response, user=user)
+else:
+    response = "Sorry - no budget!"
+```
+
+[**Implementation Code**](https://github.com/BerriAI/litellm/blob/main/litellm/budget_manager.py)
+
+## advanced usage
+
+BudgetManager creates a dictionary to manage the user budgets, where the key is user and the object is their current cost + model-specific costs. By default this is saved to a local, but you can change it to be stored to a hosted client (either self-hosted or LiteLLM one).
+
+### get model-breakdown per user 
+
+```
+user = "1234"
+# ...
+budget_manager.get_model_cost(user=user) # {"gpt-3.5-turbo-0613": 7.3e-05}
+```
+
+[**Implementation Code**](https://github.com/BerriAI/litellm/blob/817798c692207569a17c26186d10541aa83f04e7/litellm/budget_manager.py#L71)
+
+### save budget to disk
+
+When you call `save_data()` it will check for the self.type (by default this is set to client), and save the dictionary to a local `user_cost.json` file. 
+
+```python
+# ...
+budget_manager.save_data() # 👈 save to user_cost.json()
+```
+
+[**Implementation Code**](https://github.com/BerriAI/litellm/blob/817798c692207569a17c26186d10541aa83f04e7/litellm/budget_manager.py#L83)
+
+### save budget to db (LiteLLM)
+
+Set the BudgetManager type to `client`.
+```python
+budget_manager = BudgetManager(project_name="test_project", type="client")
+# ...
+budget_manager.save_data() # 👈 saved to hosted db 
+```

+
+### save budget to db (self-hosted)
+
+Set the BudgetManager type to `client`. Overwrite the api_base
+```python
+budget_manager = BudgetManager(project_name="test_project", type="client", api_base="your_custom_api")
+# ...
+budget_manager.save_data() # 👈 saved to self-hosted db 
+```
