How Much Protein Do You Need?

Protein needs vary depending on factors such as body weight, activity level, training, and individual goals. This calculator provides an estimate using a weight-based approach.

The calculator uses different protein targets according to the selected activity level and fitness goal. The result is intended as a general estimate rather than an individualized medical recommendation.

Important: This calculator is for general informational purposes. Individual protein needs can vary, particularly for people with medical conditions or special dietary requirements.

How the Protein Calculator Works

Your body weight is converted to kilograms if necessary. The calculator then applies a protein factor based on the selected activity level and fitness goal.

Daily Protein = Body Weight (kg) × Protein Target (g/kg)

The estimated target is displayed in grams of protein per day.
