OCI File Storage Calculator
Price OCI File Storage including the snapshot capacity that daily change and retention quietly accumulate.
About OCI File Storage Calculator
File Storage charges one per-GB-month rate for everything it holds, and snapshots are not free capacity: each daily snapshot pins the blocks that changed that day, so the retained volume is the daily delta multiplied by the retention window. At a 3% daily change rate, a fortnight of snapshots adds around 42% on top of the active data. Snapshot growth is the usual reason a file system bill is double what the active data suggests, and the fix is retention policy rather than capacity — halving retention halves that component immediately. Confirm the per-GB price in the Oracle Cloud cost estimator for your region, and remember mount targets add no capacity charge of their own.
Formula
OCI File Storage
snapshot capacity = active GB × daily change % × retention days; monthly = (active GB + snapshot GB) × per-GB price.
- daily change %
- Fraction of the file system rewritten each day, which snapshots must retain
- retention days
- How long each daily snapshot is kept
- snapshot capacity
- Extra billed GB held by the snapshot chain

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is OCI File Storage calculated?
snapshot capacity = active GB × daily change % × retention days; monthly = (active GB + snapshot GB) × per-GB price. File Storage charges one per-GB-month rate for everything it holds, and snapshots are not free capacity: each daily snapshot pins the blocks that changed that day, so the retained volume is the daily delta multiplied by the retention window. At a 3% daily change rate, a fortnight of snapshots adds around 42% on top of the active data.
Why does OCI File Storage matter?
Snapshot growth is the usual reason a file system bill is double what the active data suggests, and the fix is retention policy rather than capacity — halving retention halves that component immediately. Confirm the per-GB price in the Oracle Cloud cost estimator for your region, and remember mount targets add no capacity charge of their own.
What values do I need to enter?
This calculator takes 6 inputs: Active file data, Daily change rate, Snapshot retention, Price per GB-month, Mount targets, Clients mounting the file system. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
