Body Fat Percentage (BFP) Formula

Here is the formula for calculating the BFP in both imperial & metric units.

Imperial Units:

For Males:

 BFP = 86.01 ✕ [log₁₀ (A − N)] − 70.041 ✕ [log₁₀ (H)] + 36.76

For females:

 BFP = 163.205 ✕ [log₁₀ (W + C − N)] − 97.684 ✕ [log₁₀ (H)] − 78.387

Here: A is Abdomen [in], C is Hip Circumference [in], H is Height [in], N is Neck [in], and W is Waist [in]

Metric Units:

For Males: 

BFP = 495 / (1.0324 − 0.19077 ✕ [log₁₀ (W − N)] + 0.15456 ✕ [log₁₀ (H)]) − 450

For Females:

 BFP = 495 / (1.29579 − 0.35004 ✕ [log₁₀ (W + C − N)] + 0.221 ✕ [log₁₀ (H)]) − 450

Here: A is Abdomen [cm], C is hip Circumference [cm], H is Height [cm], N is Neck [cm], and W is Waist [cm]

How to Calculate Body Fat Percentage?

• For calculating body fat, we need only measuring tape.
• Using measuring tape, measure the height, then the circumference of your waist, & lastly the circumference of your neck.
• Once we get these 3 measurements, then we can use the formula according to the imperial or metric units that we use. 
• Your body needs a certain level of body fat to function properly. If your body fat percentage is too high or too low, you are unhealthy.

Body Fat Percentage Chart

Male (in %)	Female (in %)	Remarks
2 – 5%	10 - 13	Minimum essential
6 – 13	14 – 20	Athlete
14 – 17	21 – 24	Fit people
18 – 25	25 – 31	Acceptable

Solved Example of Calculating Body Fat Percentage

Example:

Mathew has a height of 166cm, waist size is 90cm & neck size is 30cm. What is his BFP?

Solution:

Here, let us first write the formula,

BFP = 495 / (1.0324 − 0.19077 ✕ [log₁₀ (W − N)] + 0.15456 ✕ [log₁₀ (H)]) − 450

Here, W = 90cm, N = 30cm & H = 30cm

Now, Body Fat = 27.7%
