Protein Calculator

The Protein Calculator estimates a daily protein target using the body weight and other information requested by the tool. Protein needs can differ according to body size, activity, goals, age, and health circumstances.

Protein calculation

A simple weight-based approach calculates protein grams by multiplying body weight in kilograms by a selected protein factor in grams per kilogram. The appropriate factor depends on the purpose of the estimate.

Using the calculator

Enter your weight and select the activity level or goal when requested. Check the unit of body weight before calculating because pounds must be converted to kilograms when a grams-per-kilogram factor is used.

Interpreting the result

The result is a general planning estimate. People with specific medical or nutritional needs may require individualized guidance from a qualified professional.
