Hi there,

The Droplet resources like CPU, RAM and Disk are fixed, autoscaling is not an option. So the price of the Droplet itself is fixed per hour/month so if you have a CPU-intensive process running on the Droplet due to an infinite loop, it will not affect the costs.

The only thing that you could get charged additionally is for bandwidth. You could use this Bandwidth calculator tool here to check the costs:

What you could do is to set up Billing alerts so that you get early notifications when you reach a certain usage amount. You can do that via your Control Panel -> then go to Billing -> then under Billing Alerts hit the ‘Add Alert’ button.

Hope that this helps!
Regards,
Bobby
