About Us

Our Mission

Daily Protein Intake Calculator was built to answer one simple question: "How much protein should I eat each day?". Too often, nutrition guidance is vague or one-size-fits-all. We wanted a free, fast, and science-backed tool that gives every person a personalized daily protein target in seconds. Try it now with our free daily protein calculator.

What We Do

Our protein calculator uses established metabolic equations (such as Mifflin-St Jeor for basal metabolic rate) combined with evidence-based protein recommendations. Depending on your goal, it applies the protein ratios recommended by leading sports nutrition bodies, including the International Society of Sports Nutrition (ISSN) and the American College of Sports Medicine (ACSM). Once you have your target, the meal planner helps you split it across your day.

Why Trust Our Numbers

Every recommendation on this site is grounded in published research. The ranges we use:

• 0.8 g/kg – baseline protein needs for sedentary adults (RDA).
• 1.2–1.6 g/kg – for active individuals and general fitness.
• 1.6–2.2 g/kg – for muscle gain, fat loss, and athletic performance.

Who It's For

Whether you're a bodybuilder maximizing muscle protein synthesis, an endurance athlete managing recovery, someone losing weight while preserving lean mass, or simply a health-conscious person tracking your daily intake – our calculator is designed to work for you. It supports both metric and imperial units and includes a meal splitter, protein-rich food portions, and a daily log tracker.

Our Commitment

This tool is free to use, and your data never leaves your device. We are committed to keeping the calculator accurate, up to date, and free of clutter or paywalls.
