Calculate body fat percentage using measurements or BMI method.
About Body Fat Calculator
The Body Fat Calculator is one of the tools fitness enthusiasts and athletes reach for most on ToolsOfIndia, and it works equally well on a phone or a desktop. Estimate body fat percentage using the US Navy method, which takes height, neck and waist (and hip for women) measurements, and the tool returns the body fat percentage along with the category - essential, athletic, fit, average or obese. Because BMI ignores muscle, body fat is a better health marker for fit people, and the tool explains that the Navy method is an estimate, not a DEXA scan. The Indian context of higher visceral fat at lower body weight is flagged, so the tool adds a note for South Asian risk. Measurements can be entered in centimetres or inches, and the formula is shown so the result is verifiable. It is the practical alternative when calipers or a scan are not available. Every default assumes Indian conditions, from metric units to INR prices, so the output is usable the moment you read it. Real-world uses include tracking a cutting phase, comparing fat with a BMI reading, and checking fitness for a sports trial. The layout stays simple on purpose: no clutter, no dark patterns, just the answer you came for.

How accurate is the Navy method?
It gives a close estimate using tape measurements, within a few per cent of a DEXA scan for most people, but it is not a clinical measurement.
Why does body fat matter more than BMI?
BMI cannot tell muscle from fat, so a muscular person may score overweight on BMI while having low body fat, which body-fat measurement reveals.
