Enter the coupling power and the input power into the Calculator. The calculator will evaluate the Coupling Loss.

## Coupling Loss Formula

CL = -10 * LOG ( 1- CP/IP)

Variables:

- CL is the Coupling Loss ()
- CP is the coupling power
- IP is the input power

## How to Calculate Coupling Loss?

The following steps outline how to calculate the Coupling Loss.

- First, determine the coupling power.
- Next, determine the input power.
- Next, gather the formula from above = CL = -10 * LOG ( 1- CP/IP).
- Finally, calculate the Coupling Loss.
- 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.

coupling power = 573

input power = 234
