Macro Goal Calculator
Macros (macronutrients) are the nutrients that supply calories: protein, carbohydrates, and fats. Protein and carbs provide 4 kcal per gram; fat provides 9 kcal per gram. This calculator gives you daily targets for each based on your body size, activity, and goal.
What Is the Macro Goal Calculator?
The macro goal calculator is a free tool that sets daily targets for protein, carbohydrates, and fat based on your body size, activity, and goal. Macros are the nutrients that supply calories: protein and carbs have 4 kcal per gram, fat has 9. This calculator gives you grams per day and optional calorie splits so you can plan meals and track intake.
How Does the Macro Goal Calculator Work?
You enter your weight, activity level, and goal (fat loss, maintenance, or muscle gain). The calculator estimates your daily calories (or uses your input) and allocates a share to protein (grams per kg body weight), then splits the remaining calories between carbs and fat using evidence-based ratios. You see daily grams for each macro and how they add up to your calorie target.
Why Use This Macro Calculator?
Hitting the right macros supports muscle retention during a cut, muscle gain in a surplus, and steady energy. This macro calculator turns a calorie goal into concrete protein, carb, and fat targets. Use it with our calorie calculator and protein calculator to align intake with your goals.
Who Should Use This Tool?
Anyone who wants to plan protein, carbs, and fat — for fat loss, maintenance, or muscle gain — can use this macro goal calculator. It suits people who already have a calorie target and want to break it into macros, and those who want one tool to set both calories and macros. Combine with the TDEE calculator for a full nutrition plan.
Is This Calculation Accurate?
Macro targets are based on common evidence-based ranges (e.g. protein by body weight and goal). Individual needs can vary. Use the macro calculator output as a starting point and adjust based on energy, performance, and results. For exercise context, try our calorie burn calculator.
