The Macro Split Calculator divides total daily calories into custom protein, carb, and fat percentages. This free Macro Split Calculator gives you an instant result based on standard nutrition guidelines and food science values. Use it to plan meals, track intake, or adjust recipes.

The formula behind this calculator: Converts each macro's percentage of total calories into grams using 4 cal/g (protein/carbs) and 9 cal/g (fat). As a practical example: A 40/30/30 split on 2,200 calories gives 220g protein, 165g carbs, and 73g fat. All results are calculated instantly in your browser — no data is stored or transmitted.
