Pricing
Object Storage is billed on peak usage per calendar month, in two slabs, plus data transfer.
Storage Pricing
| Slab | Peak usage per calendar month | Monthly rate (excluding GST) | Notes |
|---|---|---|---|
| Slab 0 | 0 GB to 250 GB | ₹625 flat | Charged as a flat amount anywhere in this range |
| Slab 1 | Beyond 250 GB | ₹2.5/GB | Applied to peak usage for the month |
Data transfer: ₹3/GB.
Capacity is not pre-allocated — the bucket grows with your data, and there is nothing to resize.
What Peak Usage Means
Peak usage is the highest amount of storage the bucket reaches at any point during the calendar month. The bill is calculated on that peak, not on the average or the end-of-month figure.
Example:
| Period | Stored |
|---|---|
| Day 1–10 | 100 GB |
| Day 11–20 | 400 GB (peak) |
| Day 21–30 | 200 GB |
You are charged for 400 GB → 400 × ₹2.5 = ₹1,000.
Deleting data late in the month does not lower that month's bill, because the peak has already been reached. Delete early, or use a lifecycle rule so cleanup happens continuously.
Versioning and Cost
Every object version is stored and billed. With versioning enabled, overwriting a 10 GB file ten times leaves 100 GB on the bill, not 10 GB. Pair versioning with a lifecycle rule so old versions expire.
Worked Examples
100 GB of image data
Peak usage stays inside Slab 0, so the charge is the ₹625 flat rate regardless of whether you store 10 GB or 250 GB. The same data on a 100 GB disk would cost ₹1,000.
500 GB of video data
Peak usage is in Slab 1: 500 × ₹2.5 = ₹1,250. On disk, 500 GB would cost ₹5,000.
Data growing from 50 GB to 300 GB
Object Storage scales automatically, so the bill moves from ₹625 (Slab 0) to 300 × ₹2.5 = ₹750 as the data grows, with no action from you. A disk would need a manual resize at each step and would reach ₹3,000.

Cost Optimization
- Pick the right type. Use Object Storage for large, shared, or growing data; a disk only when you need read-write access or low-latency random reads at a small, predictable size.
- Expire what you do not need. Lifecycle rules remove temporary data and old versions automatically.
- Compress before uploading. Fewer, denser files cost less and upload faster. Prefer efficient formats such as Parquet over CSV.
- Watch the peak. A short-lived spike sets the month's bill. Stage large intermediate work on a disk and move only the result into Object Storage.
Frequently Asked Questions
Am I charged for data transfer?
Yes, at ₹3/GB. Check your billing details for the full transfer breakdown.
Can I switch an existing bucket to Block Storage to save cost?
No. A bucket cannot be converted into a disk. Create a Block Storage disk and copy the data across.
Is encryption free?
Yes. Both E2E Managed and User Managed encryption are provided at no extra cost.
Do delete markers and old versions count toward my bill?
Old versions do. Use a lifecycle rule to expire them.
