Cloud storage cost estimator
Enter your volume and access habits with the unit prices from your provider's current price list; see monthly and yearly cost per tier, a 3-year projection with growth and what the same data would cost in another tier. The tool contains no provider prices.
Enter unit prices from your provider's current price list and your contract. Prices vary by region, volume tier and over time; this tool contains no prices.
Example prices are made-up round ratios and do not reflect any provider; they are only for trying out the tool.
Results
Enter at least one unit price to see the cost. To try the calculation you can use the hypothetical example prices below.
Calculation and assumptions
- Storage = volume (GB) × storage price. Requests = number of requests / 1000 × price per 1,000.
- Egress = egress GB × egress price. Retrieval = retrieved GB × retrieval price.
- Early deletion = early-deleted GB × storage price × max(0, minimum days − age at deletion) / 30.
- Month k factor = (1 + growth)^k, k = 0…35. Yearly without growth = 12 × today's monthly.
The volumes and prices you enter are processed in your browser; they are not sent to a server and not stored.
This is a preliminary estimate based only on the unit prices you enter. Tiered pricing, free allowances, discounts, taxes, inter-region transfer, API-specific charges and exchange-rate changes are not included. Verify against the provider's official price calculator and your contract before deciding.
Shall we review your cloud storage architecture, tier policies and migration plan together?

How to use
A
Choose the currency and monthly growth; enter the storage, request, egress and retrieval unit prices per tier from your provider's price list.
B
For each tier enter the stored volume, monthly requests, egress and retrieval, and the minimum retention and early-deleted data if any.
C
Review the monthly and yearly cost, the tier comparison and the 36-month projection; change volume or access assumptions to compare scenarios.
02
What makes up the cost?
In cloud object storage the bill is not only stored GB. Request charges (read, write, list), egress to the internet and, in cool and archive tiers, retrieval charges are added to the storage fee. In the hot tier storage is dear and access is cheap; in the archive tier storage is cheap but retrieval and requests are dear.
So the tier that looks cheapest is not always cheapest: archive suits data read rarely, the hot tier suits data read often. The 'if all data were in this tier' column shows how the same access plays out under different price structures.
03
Minimum retention and early deletion
Most cool and archive tiers require data to stay for a set period (for example thirty or one hundred and eighty days). Data deleted or moved to another tier before then may still be charged for the remaining days of storage. Moving data too early with lifecycle rules can therefore cause unexpected cost.
The tool adds this effect to the monthly cost from the early-deleted volume and the age at deletion you enter. If your provider's rule differs (for example the full period rather than the remaining days), interpret the result accordingly.
04
Growth projection and assumptions
The projection assumes the volume grows at a constant rate each month; requests, egress and retrieval optionally grow at the same rate. Real growth is uneven, and lifecycle rules and deletion policies change the curve. Read the result as a scenario, not a budget commitment.
Tiered pricing, free allowances, commitment discounts, tax, exchange-rate changes and inter-region transfer charges are not included. Verify the decision with the official price calculator.
FAQ
- Is my input sent anywhere?
- No. The calculation runs entirely in code in your browser; volumes and prices are not sent to any server and are not stored.
- Why does the tool not include ready-made prices?
- Cloud prices vary by provider, region, volume tier and over time; an embedded price goes stale quickly and misleads. Entering your own price list or contract keeps the result accurate. The 'example prices' button only uses made-up ratios to try the tool.
- What is an egress charge?
- The per-GB charge for data leaving the cloud to the internet or another region. Uploading data to the cloud is usually free; pulling it back or serving it externally is charged. You can estimate monthly egress from application logs and the invoice.
- Is moving to a cool or archive tier always cheaper?
- No. Storage gets cheaper but request, retrieval and early-deletion charges rise. If data is read more than a few times a month or deleted before the minimum period, the hot tier can be cheaper. The tool's tier comparison lets you see this with your own inputs.
- Does the GB versus GiB difference matter?
- Slightly. The tool takes 1 TB = 1000 GB. If your provider bills in GiB, enter the volume in GiB and use the price per GiB-month; consistency is what matters.
