Macro Ratio & Protein Target Finder
Calculates your daily protein, fat, and carb targets in grams based on your goal, body weight, and activity level.
Get a Protein Target That’s “Enough,” Not a Guess
This calculator turns your goal (cut, maintenance, or bulk), body weight, and activity level into practical daily macro targets in grams—protein, fat, and carbs. It also tells you whether your protein target “meets,” “nears,” or “falls short” of an evidence-based range for your goal, plus gives simple meal-planning ranges you can actually follow.
Protein Leads—Then Carbs Fill the Rest After Fat Floors
First, the tool selects a protein g/kg range based on your goal (cut/maintenance/bulk) and shifts toward the higher end with higher activity, strength emphasis, and preference strictness. Next it converts grams to calories (4 kcal/g protein) and assigns fat using a practical minimum “fat floor” plus goal-based fat bands (with fat constrained to remain realistic). Finally, it estimates your calorie target from body weight and activity, applies the cut/maintenance/bulk calorie multiplier, and calculates carbs as the remaining calories (4 kcal/g carbs).
Why Your Number Might Look Different Than “Common Advice”
Protein recommendations vary because your activity level and training emphasis change how aggressively you can prioritize lean mass with the calories you can realistically maintain. Your preference strictness acts like an adherence dial: higher strictness nudges protein/fat decisions toward the “easier to hit consistently” side, while lower strictness aims for more flexible diet trade-offs. Also, the calculator’s calorie estimate is intentionally simplified, so your actual TDEE may be higher or lower—use results as a starting point and adjust after 1–2 weeks.
When Carbs Would Go Negative (and What the Tool Does)
If your chosen inputs push protein + fat too high relative to your calorie target, the calculator reduces fat first (down to the fat floor) to prevent impossible carbs. If carbs are still threatened, it slightly adjusts within the constraints to ensure the final daily totals balance. The output will always keep macros physically possible and calories consistent with the chosen goal.
Macro Targets Are a Starting Point—Not a Medical Plan
This tool does not account for conditions like kidney disease, eating disorders, pregnancy, or medication effects—if any apply, talk with a qualified clinician. The protein “adequacy” verdict is based on general g/kg ranges and won’t replace individualized assessment (e.g., recovering from injury, very low energy availability, or major body composition changes). Finally, if results don’t match your real-world progress (weight trend, performance, hunger), adjust calories or macronutrients rather than sticking rigidly to one set.
