Enter the used space and the total storage space into the calculator to determine the storage percentage. This calculator helps to understand how much of the total storage space is currently being utilized.

Storage Percentage Formula

The following formula is used to calculate the storage percentage.

SP = (US / TS) * 100

Variables:

  • SP is the storage percentage (%)
  • US is the used space (GB)
  • TS is the total space (GB)

To calculate the storage percentage, divide the used space by the total space and then multiply by 100 to get the percentage.

What is Storage Percentage?

Storage percentage is a measure of how much of the total storage capacity is currently in use. It is a useful metric for managing data storage resources, planning for future storage needs, and ensuring that a system does not run out of space unexpectedly. It can be applied to any storage medium, such as hard drives, solid-state drives, or cloud storage services.

How to Calculate Storage Percentage?

The following steps outline how to calculate the Storage Percentage.


  1. First, determine the used space (US) in gigabytes (GB).
  2. Next, determine the total space (TS) in gigabytes (GB).
  3. Next, gather the formula from above = SP = (US / TS) * 100.
  4. Finally, calculate the Storage Percentage (SP).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

used space (US) = 250 GB

total space (TS) = 500 GB
