Macro Ratio & Macro Split Calculator

Calculate your customized daily macronutrient split (Protein, Carbohydrates, and Fats) in both grams and calorie percentages. Whether following flexible dieting (IIFYM – If It Fits Your Macros), a ketogenic protocol, body recomposition, or an aggressive endurance carb-loading schedule, this calculator computes your daily targets either from your total caloric intake or directly from bodyweight-based protein requirements ($0.8 ext{ to }1.2 ext{ g/lb}$ or $1.6 ext{ to }2.4 ext{ g/kg}$). Includes interactive pie/donut macro ratios and per-meal portion schedules across 2 to 6 meals per day.
