Ultimate Macro Calculator

Track your macros with precision. See exactly how your nutrition plan leads to your goal weight—month by month. Used by coaches and athletes worldwide.

Stop guessing. Start seeing results.

Ultimate Macro Calculator takes the confusion out of nutrition planning. Enter your stats, set your goal, and instantly see a complete macro breakdown—plus a month-by-month projection showing exactly when you'll hit your target weight.

SCIENCE-BACKED FORMULAS Choose between Mifflin-St Jeor (standard) or Katch-McArdle (if you know your body fat %) for accurate BMR calculation. Your TDEE is calculated based on your real activity level—not generic estimates.

PROTEIN-FIRST MACRO PLANNING Unlike basic calculators, we prioritize protein intake based on your body weight, then intelligently distribute remaining calories between carbs and fats. Choose from preset goals (Fat Loss, Muscle Gain, Maintenance) or create a custom split.

SEE YOUR FUTURE Our 17-month projection table shows how your weight, BMR, TDEE, and macros will change as you progress. Watch your target calories adjust automatically as you get closer to your goal. No more plateau surprises.
