Add a credit card to enable pay-as-you-go services. Set a budget to alert you about high spending. I have a $10 per month budget which is more than sufficient for my needs. I like to get an alert based on forecasted spend of 100% of budget. > [!Warning] > Budgets are for alerts only! GCP will not stop your cloud services when you reach your budget. You can still get a huge bill if you mis-provision a resource or run the wrong query. Don't get a [$10,000 bill in just 22 seconds](https://medium.com/data-engineer-things/bigquerys-ridiculous-pricing-model-cost-us-10-000-in-just-22-seconds-7d52e3e4ae60). The [Google Cloud Resource Manager](https://cloud.google.com/resource-manager) helps manage billing, permissions, and service enablement for resources in projects on GCP. You can also set quotas on rates of use and allocation of resources to limit potential billing spikes. (Google sets their own quotas, to increase a quota submit a ticket to Google.) See the **Billing Report** and **Cost Table** for current and forecasted costs. If you have multiple resources, you can label each with a key-value pair to better track usage and billing (you can label each resource with multiple labels, up to 64). Billing is typically per second (minimum one minute), but varies **widely** by the resources you've provisioned and whether you're using a Marketplace solution. Helpfully, GCP will email you rightsizing recommendations based on your usage.
