Macro Calculator turns a daily calorie goal into protein, carbohydrate, and fat targets in grams, using a split you choose for your goal, the next step after setting calories with the TDEE Calculator.
Tracking macros rather than calories alone matters because the balance of nutrients shapes your results, not just the total. Protein in particular drives muscle retention and satiety, so two plans with identical calories but different protein can produce very different outcomes for body composition, which is why a deliberate split is worth setting.
The conversion uses each macro's calorie density (protein and carbs at 4 cal/g, fat at 9), so your chosen percentages become concrete gram targets. A balanced split sits around 30/40/30, higher protein suits cutting, and lower carb suits some preferences, but the consistent advice is to get adequate protein first, then divide the remainder.
Aim for consistency over time rather than hitting every gram daily; close-enough, sustained, beats perfect-but-brief. It's informational, not dietary advice, and your details never leave your browser. Pair it with the TDEE, BMR, and Calorie calculators for a complete nutrition plan.
