This guide explains how the free trial works. To sign up for the free trial and start using Google Cloud Platform services, go to the free trial sign up form.
Free trial credit: $300 for 60 days
When you sign up for the free trial, Google credits your account with $300 for you to spend on any of the Cloud Platform products. Your free trial ends when you've spent the entire credit, or when 60 days have elapsed, whichever comes first.
There are things you can do on Cloud Platform that are free regardless of whether you are in the free trial, such as transferring data into Google Cloud Storage or running a web application within the Google App Engine free quota. These actions do not use up your credit. For details, see Product Pricing.
Use all of Google Cloud Platform
During the free trial, you can use any of the Cloud Platform services: launch servers, deploy managed applications, store files, query petabytes of data, and more.
Upgrade from the free trial
When the free trial ends, you have the option to upgrade to a paid account. If you upgrade within 30 days after your free trial expires, you'll be able to keep the resources you built during the free trial.
If you upgrade to a paid account before the 60-day trial period ends, any remaining amount of your $300 credit remains in your account. This credit expires after 60 days, when your free trial period would have originally ended.
