What Is a Protein Calculator?

A Protein Calculator estimates how much protein your body needs each day based on your body weight, activity level, and fitness goal. Getting enough protein helps support muscle growth, recovery, weight management, and overall health.

Protein requirements are not the same for everyone. People who exercise regularly or want to build muscle usually require more protein than those with a sedentary lifestyle.

Daily Protein Intake Guide

Maintain Weight 0.8–1.2 g/kg of body weight
Lose Fat 1.6–2.2 g/kg of body weight
Build Muscle 1.6–2.2 g/kg of body weight
Endurance Training 1.4–2.0 g/kg of body weight
