Cloud storage cost calculator

Estimate monthly and annual cloud storage, transfer and operation costs from a bucket list.

Input

Cloud storage cost calculator

Paste a list of buckets — one per line, as name, storage size in GB, monthly outbound transfer in GB and operation count — and this tool prices each one and totals the list. It is built for the estimate you make before committing to a plan: how much will this photo archive, backup set or media library actually cost per month and per year once storage, egress and API calls are added together.

Set the price per GB of storage, the price per GB of transfer and the price per million operations to match whichever provider or tier you are comparing, since none of these are fetched or assumed. The storage class option applies a multiplier for colder tiers — infrequent access, archive and deep archive — so a mixed plan with some data on standard storage and some archived can be modeled with one setting per bucket group. A free tier allowance in GB is deducted once from the total billed transfer, the way a provider's free monthly egress quota works, not from every bucket individually. Currency and decimal places control how every price is displayed, and the output can be a compact comparison table or an itemized breakdown that spells out storage, transfer and operation cost for every bucket.

A malformed line — missing a field, a negative size, a non-numeric value — is skipped and counted separately rather than aborting the whole calculation, so one typo in a long list does not block the rest. The tool reports both the monthly and annual figures per bucket and for the list as a whole, and the live tally under the output keeps the running total in view as you edit.

Everything runs in your browser. The bucket names and numbers you paste are never uploaded anywhere, so it is safe to price out an internal infrastructure list. Copy the result, download it as a .txt file, or send it back into the input to adjust the prices and compare a second scenario.

FAQ

What format does the input need to be in?
One bucket per line: name;storage GB;transfer GB;operations, for example 'photos;500;20;1500000'. Semicolons separate the fields.
How does the storage class multiplier work?
Selecting infrequent access, archive or deep archive multiplies only the storage price per GB — transfer and operation pricing are unaffected, since this tool models the storage-side saving of colder tiers, not their retrieval fees.
How is the free tier applied when I have several buckets?
It is deducted once from the total billed transfer across every bucket, not from each bucket separately, matching how a provider grants one monthly egress allowance per account rather than one per bucket.
What happens to a line that has a mistake in it?
It is skipped and counted as an invalid line in the tally, so the rest of the list is still priced correctly.
Is my bucket list uploaded anywhere?
No. The whole calculation runs in your browser — your bucket names, sizes and prices never leave your device.
