Google Cloud Unexpected Charges: Why Is My GCP Bill So High?

How to fix it

Try these in order — the most common fix is first.

1. 1. Find the cost driver

   Copy steps
   1. Open Billing > Reports
   2. Group by Service, then by SKU and Project
   3. Check the Cost table for the largest line items
   4. Open Resource Manager to find forgotten projects
   Did this fix it? Yes No

2. 2. Stop what is billing

   Copy steps
   1. Delete or stop unused VMs, Cloud SQL instances, load balancers and disks
   2. Release unused reserved static IP addresses
   3. Shut down whole experiment projects you no longer need
   4. If a key leaked, delete or rotate it under APIs & Services > Credentials
   Did this fix it? Yes No

3. 3. Set a budget and alerts

   Copy steps
   1. Billing > Budgets & alerts > Create budget
   2. Choose Alerts only, set scope and amount; defaults alert at 50%, 90% and 100%
   3. Understand that alerts-only budgets do not cap spend; alerts can arrive hours late
   4. To stop spend automatically, use a spend cap budget (eligible services only) or a Pub/Sub notification that disables billing on the project
   Did this fix it? Yes No

4. 4. Ask Cloud Billing support

   Copy steps
   1. Go to Billing > Support and open a billing case describing the SKU and dates
   2. Billing cases can be opened on any support tier
   Did this fix it? Yes No

Symptoms

A GCP bill much higher than expected, or charges while you thought you were on free credits.

Why it happens

• Data egress (outbound network traffic) beyond the small free allowance
• Always-on resources such as VMs, persistent disks, static IPs, load balancers, Cloud NAT and Cloud SQL instances
• Services not covered by the free trial credit or Always Free tier
• Resources left running in forgotten projects or regions
• Runaway usage from a bug or leaked key (APIs, BigQuery scans)
