Macro Calculator

Calculate a complete daily protein, carbohydrate, and fat plan from calories, body weight, and goal.

Set protein by body weight (about 1.6–2.2 g/kg), give fat ~25% of calories, and fill the rest with carbohydrates. Daily totals matter more than per-meal splits.

How this calculator works

Protein uses a goal-based body-weight target, fat receives a practical share of calories, and carbohydrates receive the remaining energy.

How to use your result

Use the three daily gram targets together. Protein supports muscle retention and growth. Fat supports essential body functions and dietary flexibility. Carbohydrates provide the remaining energy for training and daily activity.

Example macro plan

For a 75 kg user eating 2,400 calories for fat loss, the calculator provides high protein, a practical fat minimum, and the remaining calories as carbohydrates. Each result includes grams and percentage of total calories.

Daily totals matter most

Per-meal values are planning aids, not strict rules. Hitting daily calories and macro totals consistently matters more than making every meal identical. Adjust food choices for preference, digestion, training time, and dietary requirements.

Important limitation

Calculator results are estimates. Pregnancy, eating disorders, medical conditions, injuries, or concerning symptoms require qualified professional guidance.

Frequently asked questions

How do I calculate my macros?

Start from your calorie target. Protein is set per kilogram of body weight, fat takes about a quarter of your calories, and carbohydrates make up the remaining energy.

What macro split is best for fat loss?

Keep protein high (around 2.1–2.4 g/kg) to preserve muscle in a deficit, with the remaining calories balanced between carbs and fats based on preference.

Do I need to hit my macros exactly?

No. Being within ~5–10 g of your protein and overall calorie target consistently is what drives results — perfection isn't required.
