Cloud Storage Cost Calculator

monthly = GB × class price + retrieved GB × retrieval price + (ops ÷ 10,000 × op price) + early-deleted GB × class price × remaining minimum days ÷ 30. The colder classes trade capacity price against access price: Archive is roughly 17× cheaper per GB than Standard but charges the most per GB retrieved and per operation. Each cold class also carries a minimum storage duration, and deleting an object early bills the remaining days as if it had stayed, which is why the early-deletion line exists.

Lifecycle rules that sweep data into Archive look like a saving until an audit or a re-processing job reads it all back, and short-lived objects in a cold class can cost more than leaving them in Standard. Confirm the per-GB, retrieval and operation prices for your location type in the Google Cloud pricing calculator.

This calculator takes 14 inputs: Data stored, Storage class, Standard price per GB, Nearline price per GB, Coldline price per GB, Archive price per GB, Data read back each month, Retrieval price per GB, Class A operations (writes, lists), Class A price per 10,000 operations, Class B operations (reads), Class B price per 10,000 operations, Data deleted before the minimum duration, Age of that data when deleted. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.

Yes. A lifecycle transition into Nearline, Coldline or Archive starts that class's minimum storage duration from the transition date, so objects rewritten frequently can incur an early-deletion charge every cycle.
