Enter your body weight and choose a goal, and this calculator estimates a daily protein range in grams using common per kilogram guidelines. Sedentary maintenance sits near 0.8 grams per kilogram, general fitness lands around 1.2 to 1.6 grams, and muscle building or fat loss on a deficit often uses 1.6 to 2.2 grams per kilogram of body weight. The tool multiplies your weight by the low and high end of the chosen band so you see a sensible range rather than a single figure.
