Quick answer
Storage cost = GB × price per GB per month × months. 500 GB at $0.023 per GB-month for 12 months costs $138.00, or $11.50 a month.
Enter the data stored, the price per GB-month and the number of months. The calculator returns the total and monthly cost. Use this cloud storage cost calculator to check your own figures.

Formula and method
Formula
cost = GB × price × months
IEEE-754 double precision; shown to the decimals indicated.
Prices vary by provider, region and tier, so enter yours. Requests and transfer are extra.
Worked examples
These examples are verified: each one is an automated test case that the live calculator must reproduce exactly.
Example 1
Inputs: Data stored = 500; Price per GB per month = 0.023; Months = 12.
| Result | Value |
|---|---|
| Total cost | $138.00 |
| Per month | $11.50 |
Example 2
Inputs: Data stored = 2000; Price per GB per month = 0.02; Months = 6.
| Result | Value |
|---|---|
| Total cost | $240.00 |
| Per month | $40.00 |
The first line is the headline result (total cost). Below it the cloud Storage Cost Calculator lists per month, which describe the same case from other angles. IEEE-754 double precision; shown to the decimals indicated.
Worked example
500 × 0.023 = $11.50 a month; × 12 = $138. A terabyte (1,000 GB) at the same price is $23 a month. Archive tiers cost far less per GB but charge for retrieval.
Not included
Egress (data leaving the cloud), request charges and replication are not included, and they can exceed the storage cost for heavy-read workloads. Check the provider's price sheet.
How the result changes with data stored
Holding every other input at the first worked example, this table changes only data stored. It shows how sensitive the answer is to that one value; each row was produced by running this calculator.
| Data stored | Total cost | Per month |
|---|---|---|
| 250 | $69.00 | $5.75 |
| 500 | $138.00 | $11.50 |
| 1000 | $276.00 | $23.00 |
| 2000 | $552.00 | $46.00 |
What happens with invalid input
These messages are produced by the calculator itself, so you know what to fix.
- Data stored: entering "0" shows "Data stored must be greater than 0." beside that field and no result.
- Price per GB per month: entering "0" shows "Price per GB per month must be greater than 0." beside that field and no result.

Background: networking and display
Network speeds are quoted in bits per second and file sizes in bytes, and a byte is 8 bits, so a 100 Mbps link moves at most 12.5 megabytes per second; real throughput is usually below the advertised rate. Pixel density is the diagonal in pixels divided by the diagonal in inches: a 1920×1080 display of 24 inches is about 92 pixels per inch, and a 3840×2160 display of 27 inches about 163.
Assumptions and limitations
- Egress and request costs are not included
If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for data stored and price per GB per month to confirm this.
Frequently asked questions
What is egress?
Data transferred out of the cloud.
Do prices drop with volume?
Often in tiers: many providers lower the per-GB price after set volume thresholds, so enter the rate for your tier.
What about growth?
Re-run with the expected size.
What does the Cloud Storage Cost Calculator calculate?
Storage cost from size and a price you enter. It returns Total cost and Per month.
What formula does the Cloud Storage Cost Calculator use?
cost = GB × price × months. Prices vary by provider, region and tier, so enter yours.
What do I need to enter in the cloud Storage Cost Calculator?
You enter Data stored (GB), Price per GB per month ($) and Months.
How is the result rounded or limited?
IEEE-754 double precision; shown to the decimals indicated. Egress and request costs are not included.
What is an example of a cloud Storage Cost result?
With data stored 500, price per GB per month 0.023 and months 12, the total cost is $138.00.
Where does the method come from?
The method follows: Your cloud provider's published price list.
