Calculate your daily protein, carbohydrate, and fat targets based on your goals.
A macro (macronutrient) calculator splits your daily calorie target into specific grams of protein, carbohydrates, and fats based on your fitness goal — cutting, bulking, maintenance, or keto. Protein preserves muscle tissue and drives satiety; carbohydrates fuel athletic performance and brain function; fats support hormone production, vitamin absorption, and long-term energy. Tracking macros gives you dramatically more control over body-composition outcomes than just tracking calories alone, because 2,000 kcal of mostly protein vs mostly sugar produces completely different results over time.
Formula
Protein = 4 kcal/g. Carbs = 4 kcal/g. Fat = 9 kcal/g. Grams of each macro = (Calories × % of that macro) ÷ kcal per gram.Calorie counting alone doesn't tell you the whole story — 2,000 calories of mostly chicken and lentils builds a very different body than 2,000 calories of mostly white rice and sweets. Macros (protein, carbs, fat) are the next layer of control. Protein preserves muscle while you diet, makes you feel full, and is the single most under-eaten nutrient in the typical Pakistani or Indian household diet, which tends to run carb-heavy at 70-plus percent. Carbs fuel hard training and brain work — they're not the villain Instagram makes them out to be, but quality matters (oats, brown rice, whole wheat roti beat white naan and Mountain Dew). Fats keep hormones working, vitamins absorbing, and skin from looking like cardboard — never drop below 20 percent of calories from fat for any length of time. For most people doing body recomposition, 30/40/30 (protein/carbs/fat) is a clean starting split. For fat loss, push protein up to 35 to 40 percent. For muscle gain, drop protein slightly and load carbs. For keto, invert almost everything. Honest take: macro tracking is a 4 to 8 week learning exercise. Once you've weighed your meals long enough to eyeball portions accurately, you can usually drop the app and maintain results just by remembering what 30 grams of chicken looks like on your plate. Weigh, learn, then live.

Each macronutrient has a fixed energy density: protein and carbohydrates both deliver 4 kcal per gram, while fat is more than double at 9 kcal per gram (which is why high-fat foods are calorie-dense). To convert a macro percentage split into grams, multiply your total daily calories by the percentage assigned to that macro, then divide by its kcal-per-gram value. The calculator handles the arithmetic automatically across several popular split patterns (balanced, cutting, bulking, keto).
Recommended protein / carb / fat gram totals for each goal at different daily calorie targets.
| Goal | Split (P/C/F) | 1,800 kcal | 2,000 kcal | 2,500 kcal | 3,000 kcal |
|---|---|---|---|---|---|
| Fat Loss | 40/30/30 | P180 C135 F60 | P200 C150 F67 | P250 C188 F83 | P300 C225 F100 |
| Maintenance | 30/40/30 | P135 C180 F60 | P150 C200 F67 | P188 C250 F83 | P225 C300 F100 |
| Muscle Gain | 25/50/25 | P113 C225 F50 | P125 C250 F56 | P156 C313 F69 | P188 C375 F83 |
| Keto | 25/5/70 | P113 C23 F140 | P125 C25 F156 | P156 C31 F194 | P188 C38 F233 |
| High Protein | 45/30/25 | P203 C135 F50 | P225 C150 F56 | P281 C188 F69 | P338 C225 F83 |
Protein = 4 kcal/g, Carbs = 4 kcal/g, Fat = 9 kcal/g — the universal macro-to-calorie conversions.
30 g protein ≈ one chicken breast, or 4 large eggs, or 1 scoop whey protein.
Most Pakistani/Indian diets are carb-heavy (70%+) — inverting the ratio toward 30–40% protein helps weight management.
Athletes often need 2.0–2.4 g protein per kg body weight — double the general population's requirement.
A 2,500 kcal balanced day (30% protein, 40% carbs, 30% fat) gives 188 g protein, 250 g carbs, and 83 g fat.
A 2,000 kcal cutting day (40/30/30) gives 200 g protein, 150 g carbs, and 67 g fat — high protein preserves muscle during a deficit.
A 3,000 kcal bulking day (25/50/25) gives 188 g protein, 375 g carbs, and 83 g fat — plenty of carbs to fuel muscle-building workouts.
A 2,000 kcal keto day (25/5/70) gives 125 g protein, 25 g carbs, and 156 g fat — very low carb, very high fat, the defining keto split.
An athlete aiming for 1.8 g/kg protein at 80 kg body weight needs 144 g daily — prioritize protein first, then fill carbs and fat to meet calorie target.
A sedentary office worker at 1,800 kcal with 25/50/25 split gets 113 g protein, 225 g carbs, and 50 g fat — lighter macros matched to light activity.
