Macro Calculator

Split calories into protein, carbs and fats for a chosen fitness goal.

Calories first. Macros second.

What are macros?

Macros are protein, carbohydrates and fats. This calculator converts calories into gram targets for each macro.

Simple beats perfect

Use this as a repeatable target. Constantly changing macros makes tracking harder than it needs to be.

Subtle gear note: if you train regularly, comfortable activewear helps remove friction. Browse Layna Activewear when you actually need gym-ready pieces — not before.
