Enter the total weight of muscle (lbs) and the total weight of fat (lbs) into the Muscle to Fat Ratio Calculator. The calculator will evaluate and display the Muscle to Fat Ratio. 

Muscle to Fat Ratio Formula

The following formula is used to calculate the Muscle to Fat Ratio. 

MFR = WM / WF

  • Where MFR is the Muscle to Fat Ratio
  • WM is the total weight of muscle (lbs) 
  • WF is the total weight of fat (lbs) 

How to Calculate Muscle to Fat Ratio?

The following example problems outline how to calculate Muscle to Fat Ratio.

Example Problem #1:

  1. First, determine the total weight of muscle (lbs). 
    • The total weight of muscle (lbs) is given as: 30.
  2. Next, determine the total weight of fat (lbs). 
    • The total weight of fat (lbs) is provided as: 40.
  3. Finally, calculate the Muscle to Fat Ratio using the equation above: 

MFR = WM / WF

The values given above are inserted into the equation below and the solution is calculated:

MFR = 30 / 40 = .75


Example Problem #2: 

For this problem, the variables required are provided below:

total weight of muscle (lbs) = 50

total weight of fat (lbs) = 60

Test your knowledge using the equation and check your answer with the calculator above.

MFR = WM / WF = ?
