Enter the current bandwidth and the total available bandwidth into the Calculator. The calculator will evaluate the Bandwidth Use. 

Bandwidth Use Formula

BU = CB / TB * 100


  • BU is the Bandwidth Use (%)
  • CB is the current bandwidth
  • TB is the total available bandwidth

To calculate Bandwidth Use, divide the current bandwidth by the total available bandwidth, then multiply by 100.

How to Calculate Bandwidth Use?

The following steps outline how to calculate the Bandwidth Use.

  1. First, determine the current bandwidth. 
  2. Next, determine the total available bandwidth. 
  3. Next, gather the formula from above = BU = CB / TB * 100.
  4. Finally, calculate the Bandwidth Use.
  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.

current bandwidth = 600

total available bandwidth = 6000
