How to Calculate Daily Protein Intake

A protein calculator estimates your daily protein needs based on body weight, activity level, and fitness goals. Protein is crucial for muscle maintenance and overall health.

The Formula

Protein (g) = Body Weight x Protein Factor

Where:

ProteinDaily Protein — Grams of protein needed daily

BWBody Weight — Weight in kg or pounds

FactorProtein Factor — Grams per unit weight for goal

Step-by-Step Example

Here's how to calculate daily protein intake step by step:

1Measure body weight: Weigh yourself in pounds or kilograms.
2Choose your factor: Sedentary: 0.36g/lb, active: 0.5-0.7g/lb, muscle building: 0.7-1g/lb.
3Multiply: Multiply your weight by the chosen protein factor for daily grams needed.

Following these 3 steps gives you the final daily protein intake value.

A 160-pound person building muscle needs 160 x 0.8 = 128g protein per day, equivalent to about 4 chicken breasts.
