Enter the total power (watts) and the number of channels into the Calculator. The calculator will evaluate the Watts Per Channel. 

Watts Per Channel Formula

WPC = P / C


  • WPC is the Watts Per Channel (watts/channel)
  • P is the total power (watts)
  • C is the total number of channels

To calculate Watts Per Channel, divide the total power in watts by the total number of channels.

How to Calculate Watts Per Channel?

The following steps outline how to calculate the Watts Per Channel.

  1. First, determine the total power (watts). 
  2. Next, determine the total number of channels. 
  3. Next, gather the formula from above = WPC = P / #C.
  4. Finally, calculate the Watts Per Channel.
  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.

total power (watts) = 48

total number of channels = 3
