PUTTING IT INTO PRACTICE
Cloud Storage Cost: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Average stored decimal GB | 500 |
| Price per GB-month | 0.02 |
| Months | 12 |
| Result | 120 currency units |
- Check the input labels and enter the example values above.
- Apply the relationship: Storage cost = average GB × monthly unit price × months.
- The result is 120 currency units, rounded for display.
How to interpret your result
Excludes requests, retrieval, transfer, minimum-retention and tiered charges.
Specify decimal or binary units before comparing storage totals. Full-backup retention differs from incremental or deduplicated backup plans. Compression can sometimes increase size when data is already compressed.
Frequently asked questions
Is a 4:1 compression ratio a 400% saving?
No. It means the compressed size is one quarter of the original, corresponding to a 75% size reduction.
When is the cloud storage cost calculator useful?
Estimate simple flat-rate cloud storage charges from average usage. Excludes requests, retrieval, transfer, minimum-retention and tiered charges.
How do I use the cloud storage cost calculator?
Enter average stored decimal gb, price per gb-month, months. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Storage cost = average GB × monthly unit price × months.
What should I check before using the result?
Excludes requests, retrieval, transfer, minimum-retention and tiered charges.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
