Both calculators run independently — change the inputs on either side to compare results.
Macro Calculator
Split your daily calorie target into grams of protein, carbohydrates, and fat tuned to your goal — fat loss, muscle gain, maintenance, or keto. The output is the macro target sports-nutrition coaches and bodybuilders use to plan meals and track adherence with apps like MyFitnessPal or Cronometer.
BMR / TDEE Calculator
Estimate your daily calorie needs using the revised Harris-Benedict equation, then adjust for activity to get your Total Daily Energy Expenditure (TDEE) — the rough number of calories you burn in 24 hours when you eat a maintenance diet. Enter your weight in kilograms, height in centimetres, age, biological sex, and an activity multiplier (sedentary 1.2, lightly active 1.375, moderately active 1.55, very active 1.725, extremely active 1.9). The result is what most nutrition guides call your "maintenance calories" — a starting point for designing a deficit (to lose weight), a surplus (to gain muscle), or a recomposition plan.
