How to use the cloud storage cost calculator
Prepare the values for this calculation
Estimate cloud object-storage cost from average stored GB, monthly storage rate, outbound transfer and transfer rate. Use the formula below to check that it answers your question. Read the input units before transferring figures from a statement, measurement or dataset.
Enter and check each input
- Average stored data (GB): enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Storage price ($/GB-month): enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Outbound data (GB/month): enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
- Egress price ($/GB): enter a value at least 0. Use the unit named in the label or selected above. Do not leave this required field blank.
The input table gives a complete example. Keep units and time periods consistent across related fields.
Calculate and resolve any input error
Choose Calculate after entering the values. Changes also update the answer after a short pause. If an error appears, follow its message, correct the field and calculate again. Reset restores the example values.
Interpret the answer
Check Estimated monthly cost first. With the unchanged example inputs, it is $65.00. Compare the additional metrics with the primary result; each has its own label and unit.
Compare and keep a useful result
For a controlled comparison, keep every other example input unchanged and change Average stored data (GB) from 1000 to 1100. The resulting Estimated monthly cost is $67.00. This illustrates the equation’s response to that input, rather than a forecast of real events.

Cloud Storage Cost Calculator formula
Monthly cost = storage GB×storage rate + egress GB×egress rate.
Inputs and units
| Input | Format / range | Example |
|---|---|---|
| Average stored data (GB) | minimum 0 | 1000 |
| Storage price ($/GB-month) | minimum 0 | 0.02 |
| Outbound data (GB/month) | minimum 0 | 500 |
| Egress price ($/GB) | minimum 0 | 0.09 |
Worked example
Using the example inputs above, the estimated monthly cost is $65.00.
- Estimated monthly cost
- $65.00
- Storage component
- $20.00
- Egress component
- $45.00
Results and assumptions
This excludes API request, retrieval-tier, minimum-duration, tax and provider-specific charges unless included in the rates you enter.
Fix an input or unexpected result
Average stored data (GB) is required. Enter average stored data (gb) using the format and bounds in the input table. Zero and an empty field are different: use zero only if it is allowed and represents your data.
If your answer differs from the example, choose Reset and compare every field, including selected units and options. Check percentage versus decimal entry and whether values describe the same period. Round only the final displayed answer when reproducing the formula.
