What this calculator does
The Cloud Data Storage Cost Calculator estimates how much you will pay to store data in the cloud (or on any per-GB metered storage service). It multiplies the amount of data you keep by the price you are charged per gigabyte each month, then projects that cost over any number of months. It is a universal pricing tool — plug in the rate from any provider (object storage, block storage, backups, archives) to compare plans.
How to use it
Enter three values: the total Storage (GB) you need, the Price per GB / month your provider charges, and the Duration in months you want to project. The calculator returns the total cost for that period, plus the recurring monthly cost and the equivalent annual cost so you can budget easily.
The formula explained
The math is simple but easy to get wrong with unit confusion: $$\text{Cost} = \text{Storage}_{\text{GB}} \times \text{Price}_{\text{GB/month}} \times \text{Months}$$ The monthly cost is just storage \(\times\) price, and the total is that figure repeated over the duration. Note that 1 TB = 1,000 GB on most cloud bills (decimal), so a 2 TB dataset is 2,000 GB.
Worked example
Suppose you store 1,000 GB at $0.023 per GB per month for 12 months. Monthly cost = $$1{,}000 \times 0.023 = \$23.00$$ Total cost = $$23.00 \times 12 = \$276.00$$ The annual cost line also shows $276.00 because the duration here is exactly 12 months.
FAQ
Does this include data transfer or request fees? No. This estimates storage capacity cost only. Egress, API requests, and retrieval fees are billed separately by most providers.
Should I use GB or GiB? Use the unit your provider bills in. Most cloud providers price per GB (decimal, 1 GB = 1,000 MB), not GiB.
Can I compare two providers? Yes — run the calculator twice with each provider's per-GB rate and the same storage and duration, then compare the totals.
