SharePoint storage cost calculator.
Work out what your SharePoint storage really costs — and what you’d stop paying by archiving cold files to object storage. Move the sliders to your tenant’s numbers. No sign-up, no sales call, just the maths the way your CFO will want to see it.
Reading your storage cost.
The included allocation it subtracts first
Microsoft pools SharePoint storage at 1 TB per tenant plus 10 GB per eligible licence (Microsoft’s SharePoint limits documentation, last verified July 2026). The calculator subtracts that allocation before counting any overage — only storage above the pool costs you anything. Not every licence type adds the 10 GB (frontline and some kiosk plans don’t), so if you know your tenant’s exact allocation from the Microsoft 365 admin centre, enter it above and the calculator uses your figure instead.
The Microsoft rate it compares against
SharePoint storage over the pooled allocation is billed at roughly US$0.20/GB/month via the Office 365 Extra File Storage add-on — about A$290 (US$200) per terabyte per month. That's the number the calculator holds cold data up against.
Why the cold-data slider matters most
You don't archive everything — only the aged files nobody opens. In most tenants that's the majority of the volume. The cold-data slider sets how much of your total is archivable; the savings scale directly with it.
What ArchiveBridge charges instead
Management is A$29/TB/month with your own Wasabi or Backblaze B2 bucket, or A$49/TB/month all-in if we host the storage — metered daily, no per-seat licences, free restores. The gap between that and the Microsoft rate is your saving.
This is an estimate — the scan is exact
Every assumption above is stated and checkable. A free read-only scan reads your real tenant and returns the exact reclaimable volume, with a dollar estimate at the stated rates — your actual saving also depends on your licence mix and Microsoft contract pricing. The estimate exists only to tell you whether the scan is worth five minutes.
