MacroFit is a free calorie and macro calculator designed to estimate your daily calorie needs and give you a practical macronutrient split for weight loss, muscle gain or maintenance. Enter your age, height, weight, gender, activity level and goal to calculate an estimated daily target for calories, protein, carbohydrates and fats.
A calorie calculator estimates how much energy your body may need per day. MacroFit uses formula-based calculations to estimate your basal metabolic rate and your total daily energy expenditure. This gives you a starting point for planning meals, tracking progress and adjusting your intake over time.
Macros are the three main macronutrients in your diet: protein, carbohydrates and fats. Protein helps support muscle maintenance, carbohydrates provide training and daily energy, and fats are important for general nutrition. A good macro split makes your calorie target easier to use in real life.
Your goal changes how you should read your result. For weight loss, a moderate calorie deficit is usually the starting point. For muscle gain, a controlled calorie surplus can help support training progress. For maintenance, the goal is to stay close to your estimated daily energy needs.
Important: MacroFit provides general informational content only. The calculator and PDF plan are not medical, nutritional or therapeutic advice. If you have medical conditions, pregnancy, eating disorders, medication use or special dietary needs, consult a qualified professional before changing your diet or training routine.
