What are Class A and Class B operations in GCP Cloud Storage?

Class A operations include writes, object listings, and metadata updates. Class B operations include reads and object existence checks. Class A operations cost more than Class B. The estimator breaks down costs by operation class so you can see where your spend concentrates.

What happens if I delete an Archive-class object before 365 days?

GCP charges an early deletion fee equal to the storage cost for the remaining days of the minimum storage duration. For Archive class, that is 365 days. The estimator warns you about this and calculates the penalty so you can decide whether a cheaper class is truly cheaper for your access pattern.

Does the tool support multi-region and dual-region buckets?

Yes. You can select multi-region (e.g., US, EU, ASIA) or dual-region configurations. Multi-region and dual-region buckets cost more per GB but provide higher availability and geo-redundancy. The estimator adjusts pricing accordingly.

About This Tool

The GCP Cloud Storage Cost Estimator projects your monthly Google Cloud Storage costs across Standard, Nearline, Coldline, and Archive storage classes in any supported region. Enter your data volume, operation counts (Class A and Class B), retrieval amounts, and egress destinations to get a detailed cost estimate. The tool highlights minimum storage duration charges for Nearline (30 days), Coldline (90 days), and Archive (365 days) that can catch teams off guard. Use it to compare regions and storage classes side by side to find the cheapest configuration that meets your access pattern and durability needs.

When to Use This Tool

•Estimating monthly costs for hosting a data lake on Standard storage in a multi-region bucket versus a single-region bucket.
•Comparing Nearline versus Coldline for database backups accessed once a quarter.
•Calculating retrieval costs when restoring a large dataset from Archive storage for an annual compliance review.
•Modeling egress costs for serving Cloud Storage objects through Cloud CDN versus direct internet downloads.
