If, for example. I launch an instance, use it for 10 minutes, terminate it. and shortly after I start a new instance. Will I be charged twice?

❌ NO. You are billed while each instance is running, so stopping the first one ends that charge and starting a new one starts a new charge period. The docs warn that credit is deducted “as long as the instance is running,” and the instance must be stopped to avoid extra charges: gmsaas Commands.

If you want, I can also explain how to estimate the total cost for a specific cloud provider and instance type.
