Macro Calculator

Use this calculator to split your daily calories into protein, carbs, and fat using simple presets or your own custom ratio.

Use this as a planning estimate

These calculator results are designed to give you a practical starting point. They work best when you adjust from real progress rather than treating one number as exact.

Read the matching guides

Use the guides alongside the tools so the numbers make more sense in context and are easier to use day to day.

What your result means

This calculator splits your daily calories into protein, carbs, and fat targets using either a preset or your own custom percentages.

Your macro targets are planning numbers, not a rule that has to be hit perfectly every day.

How the split works

Protein and carbs are calculated at 4 calories per gram, while fat is calculated at 9 calories per gram.

Calories still matter most overall. Macros help structure that calorie target into practical daily numbers.

Worked example

Example inputs

  • Daily calories: 1,800 calories/day
  • Preset: Fat loss / higher protein
  • Split: 30% protein, 40% carbs, 30% fat

Example outputs

  • Protein: 135 g/day
  • Carbs: 180 g/day
  • Fat: 60 g/day

This example shows how the calculator converts a calorie target into macro grams using a simple preset split.

Common mistakes

  • Thinking the macro split matters more than the total calorie target.
  • Using extreme custom percentages that are hard to maintain.
  • Assuming one macro ratio is best for everyone.
