Cloud Storage Cost Calculator
Use this cloud storage cost calculator to estimate current monthly storage cost, projected end-of-period cost, and total cost over a planning window.

How to use this calculator
Enter the planning values that match your network, storage, or cloud scenario. Use realistic production assumptions when sizing anything that affects availability, performance, or cost.
Formula or calculation method
The calculator multiplies stored GB by the GB-month rate, adds optional monthly egress and request costs, then uses average stored data over the planning period for the total estimate.
Worked example
At $0.023 per GB-month, 2,000 GB costs about $46 per month before egress, requests, retrieval, and taxes.
Practical planning tips
- Object storage budget planning.
- Backup repository cost checks.
- Cloud migration estimates.
Common mistakes to avoid
- Ignoring egress and request fees.
- Using decimal TB and binary TiB interchangeably.
- Forgetting retention, versioning, lifecycle tiers, and deleted-object lag.
Frequently asked questions
Does this model every cloud provider fee?
No. It handles core storage, growth, egress, and request estimates, but provider bills can include more line items.
Should I include backup growth?
Yes. Add expected monthly retained growth, not just new production data.
