Estimate daily macros for protein, carbs, and fat based on your calories, body size, activity level, and goal. This free macro calculator supports men and women, US and metric units, and shows several common macro split styles in one place.
Calories first:
This calculator estimates maintenance calories from BMR and activity level.
Goal calories:
Weight loss and weight gain targets are adjusted from maintenance calories.
Macro split:
Protein, carbs, and fat are divided from total calories using the selected percentage split.
Grams per day:
The calculator converts calorie percentages into grams for each macro.
Macros help organize calorie intake into protein, carbohydrates, and fat. Many people use macro targets for weight loss, muscle gain, sports nutrition, and general meal planning.
Total calories still matter, but macro balance can affect hunger, performance, and food choices.
Your result shows estimated daily calories and macro targets in grams for protein, carbs, and fat, based on your goal and selected macro style.
This gives you a practical starting point for meal planning and nutrition tracking.
Macros are the three main calorie-containing nutrients: protein, carbohydrates, and fat.
Many people track both, since macros are one way to organize total daily calories.
Protein needs vary, but higher-protein macro setups are often used for weight loss and muscle-focused goals.
Body composition, food tracking accuracy, routine, training load, and metabolism can all affect real nutrition needs.
