# Macro calculator

Estimates daily calories and protein, carb, and fat targets from body stats and goal, with every assumption editable and the working shown.

Enter your stats to get daily targets.

Mifflin-St Jeor estimates resting energy from body size, an activity multiplier turns it into maintenance, and the goal cuts or adds a slice. Protein and fat are set first by your assumptions, carbohydrate fills whatever is left, all computed unrounded and only rounded for display. This is arithmetic, not medical advice: pregnancy, eating disorders, diabetes, and kidney disease all move these numbers in ways no calculator sees, so take the plan to a doctor or dietitian before acting on it.
