Cloud storage cost per TB
Last checked: 2026-11-06
Across the regular USD prices below, read on 2026-11-06, cost per TB per year ran from USD 12.00 on IDrive's largest Personal plans to USD 237.60 on iCloud+ 50 GB. The biggest driver is plan size. Bundles and business plans can cost more per TB, as the price database shows. Your real cost also depends on how much of the plan you fill.

These are our sums. Each divides the regular or renewal price for a year by the plan size. Sorted by size, not by provider.

|---|---|---|---|
| iCloud+ 50 GB | 50 GB | USD 11.88 | USD 237.60 |
| iCloud+ 200 GB | 200 GB | USD 35.88 | USD 179.40 |
| pCloud Premium 500 GB | 500 GB | USD 49.99 | USD 99.98 |
| Microsoft 365 Personal | 1 TB | USD 99.99 | USD 99.99 |
| pCloud Premium Plus | 2 TB | USD 99.99 | USD 50.00 |
| iCloud+ 2 TB | 2 TB | USD 119.88 | USD 59.94 |
| IDrive Personal | 5 TB | USD 119.88 | USD 23.98 |
| pCloud Ultra | 10 TB | USD 299.99 | USD 30.00 |
| IDrive Personal | 10 TB | USD 179.88 | USD 17.99 |
| iCloud+ 12 TB | 12 TB | USD 719.88 | USD 59.99 |
| IDrive Personal | 100 TB | USD 1,199.88 | USD 12.00 |
IDrive's plans are built around backup. Its Cloud Drive sync needs separate activation, so these are not like-for-like products. Microsoft 365 Personal includes Office apps.
Backblaze B2 is a different kind of product. It is pay-as-you-go object storage that starts at $6.95 per TB a month, or $83.40 per TB a year by our sum. You pay for what you store, but it is not a consumer drive.
Why your real cost is higher
A low cost per TB only applies if you fill the plan. Here is what happens if you do not.
| Plan | Cost a year | Storage used | Per TB bought | Per TB used |
|---|---|---|---|---|
| pCloud 2 TB | USD 99.99 | 0.5 TB | USD 50.00 | USD 199.98 |
| pCloud 2 TB | USD 99.99 | 1 TB | USD 50.00 | USD 99.99 |
| IDrive 5 TB at renewal | USD 119.88 | 1 TB | USD 23.98 | USD 119.88 |
So a person who stores 1 TB pays USD 119.88 per TB used on the 5 TB plan, and USD 99.99 on the 2 TB plan. The plan with the lower price per TB bought costs more for that person. Try your own numbers in the cost calculator. For teams, see business cost per user.
