Enter the transmitted power (dBm) and the gains minus losses (dB) into the Calculator. The calculator will evaluate the Link Budget Equation. 

Link Budget Equation Formula

RP  = TP +  (G-L)


  • RP is the Link Budget Equation (dBm)
  • TP is the transmitted power (dBm)
  • G-L is the gains minus losses (dB)

To calculate Link Budget Equation, add the transmitted power to the result of the gains minus the losses.

How to Calculate Link Budget Equation?

The following steps outline how to calculate the Link Budget Equation.

  1. First, determine the transmitted power (dBm). 
  2. Next, determine the gains minus losses (dB). 
  3. Next, gather the formula from above = RP = TP + (G-L).
  4. Finally, calculate the Link Budget Equation.
  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.

transmitted power (dBm) = 300

gains minus losses (dB) = 50
