(RFM) Relative Fat Mass Calculator

When it comes to body fat measurement, most people immediately think about BMI (Body Mass Index). However, BMI can be misleading in situations where it fails to distinguish between muscle and fat, which may lead to incorrect results for athletes, fitness enthusiasts, and even individuals with higher muscle mass.

Enter RFM – Relative Fat Mass, a modern and more accurate body fat estimation formula that only needs two simple measurements – your height and waist circumference.

The RFM Calculator is gaining popularity because it is:

✅ Simple – just height & waist measurement needed
✅ Accurate – closer to DEXA scan results than BMI
✅ Gender-specific – separate formulas for men & women
✅ Practical – no expensive tools required

In this article, we will explain what RFM is, how it is calculated, its ideal ranges, and why it is better than BMI for tracking body fat.

What is Relative Fat Mass (RFM)?

Relative Fat Mass (RFM) is a formula developed by researchers at Cedars-Sinai Medical Center in 2018 to provide a more reliable method of estimating body fat percentage without using expensive devices.

Unlike BMI, which uses weight and height, RFM uses height and waist circumference, making it much better at predicting body fat distribution and metabolic risk.

Step-by-Step Example

Ideal RFM Ranges

Here is a general classification for RFM values:

Category	Men (RFM %)	Women (RFM %)
Underfat	< 6%	< 14%
Healthy	6 – 24%	14 – 31%
Overfat	25 – 33%	32 – 40%
Obese	> 33%	> 40%

💡 These values may slightly vary by age and ethnicity.

RFM vs BMI – Which is Better?

Factor	BMI	RFM
Input Data	Height & Weight	Height & Waist
Muscle vs Fat	Cannot differentiate	Considers waist fat
Accuracy	Moderate	High
Best for	Population screening	Individual body fat estimation
Correlation with DEXA	Lower	Higher

RFM wins when it comes to measuring body composition, especially for athletes or those with high muscle mass who may be wrongly classified as overweight by BMI.
