Where object storage spend goes
At rest, storage dominates. Heavy traffic pushes egress and request fees up fast.

What the Google Cloud Storage Cost Calculator does
Google Cloud Storage keeps objects in buckets, priced on stored data, the operations you run against it, and egress to the internet. Standard storage is about $0.020 per GB per month, with cheaper Nearline, Coldline and Archive classes for data you rarely touch. Egress is about $0.12 per GB, the line that grows fastest when you serve files to users.
This Cloud Storage cost calculator adds storage, operations and egress into a monthly total so you can see the biggest slice. For cold data, moving to Nearline or Coldline cuts storage cost sharply, and fronting the bucket with Cloud CDN reduces egress.
Heads up on pricing. The rates built into this tool are public list estimates for July 2026 and can change without notice. Providers also offer batch discounts, prompt caching and volume tiers that lower real costs, so treat the output as a planning estimate, not a quote.
The formula
storage = GB × class rate
operations = (writes ÷ 1000 × $0.005) + (reads ÷ 1000 × $0.0004)
egress = GB out × $0.12
total = storage + operations + egress
operations = (writes ÷ 1000 × $0.005) + (reads ÷ 1000 × $0.0004)
egress = GB out × $0.12
total = storage + operations + egress
Worked example
Storing 500 GB Standard with 1,000,000 writes, 20,000,000 reads and 200 GB egress: storage is $10, writes $5, reads $8 and egress $24, for about $47 a month.
Ways to lower your cloud costs
- Right size resources. Pick the smallest instance, memory or capacity that still meets your performance target.
- Commit to steady load. Reserved instances, savings plans and committed use discounts cut rates sharply for predictable workloads.
- Use serverless for spiky traffic. Scale-to-zero services mean you pay nothing while there are no requests.
- Tier cold storage. Move rarely accessed data to cheaper classes such as Glacier, Coldline or Archive.
- Cut data transfer. A CDN and keeping traffic within a single region reduce the egress charges that quietly grow with scale.
Frequently asked questions
How much does Google Cloud Storage cost?
Standard storage is about $0.020 per GB per month, plus operations and egress. Cheaper classes exist for cold data. Enter your usage above for a total.
What are the storage classes?
Standard for hot data, Nearline for monthly access, Coldline for quarterly, and Archive for rarely touched data. Colder classes cost less to store but more to retrieve.
Why is egress the surprise cost?
Because serving files to users is billed around $0.12 per GB leaving Google. High download volume can make egress the largest line on the bill.
How do I lower Cloud Storage costs?
Use lifecycle rules to move cold data to Nearline or Coldline, front the bucket with Cloud CDN to cut egress, and delete unused objects.
Are these rates current?
