 ### Low balance behavior
 
-Runpod monitors your account balance and takes protective action when funds run low:
+Runpod monitors your account balance in real time. Billing runs every 5 minutes, and charges are deducted continuously based on the resources you have running.
 
-- When your account balance is no longer sufficient to cover your remaining runtime, Runpod automatically stops all your Pods.
-- Stopped Pods retain their volume storage, but you continue to accrue storage charges.
-- If your balance is completely depleted, Pods and their associated storage may be deleted.
+When your balance reaches \$0, Runpod automatically stops all of your running Pods. What happens to your data depends on whether the Pod has a network volume attached:
+
+- Pods with a network volume attached are stopped, and your data is preserved on the network volume.
+- Pods without a network volume are terminated, and their data can't be recovered.
+
+Storage charges continue to accrue on network volumes while your Pods are stopped. If your balance stays at \$0 and these charges can't be covered, the network volume may eventually be terminated, and its data can't be recovered.

+### Low balance notifications
+
+Low balance notifications alert you when your account balance drops below a threshold you define, giving you time to add funds before your workloads are interrupted.
+
+To enable low balance notifications:
+
+1. Navigate to the [Billing page](https://www.console.runpod.io/user/billing) in the Runpod console.
+2. Under **Notifications**, enable **Low balance alert**.
+3. Set the balance threshold at which you want to be notified.
+
+Runpod sends an email when your balance falls below the threshold you set. This is separate from auto-pay, so you can use one or both.
+
 ### Auto-pay
 
 Auto-pay automatically reloads your account balance when it falls below a threshold, helping you avoid service interruptions from low funds.
