Enter your weight, goal, and activity level into the calculator to determine your daily caloric intake.

Macro Calculation Formula

The following formula is used to calculate your daily caloric intake from your macronutrient needs.

Calories = (Protein (g) * 4) + (Carbs (g) * 4) + (Fats (g) * 9)

Variables:

  • Calories is the total amount of energy intake per day (kcal)
  • Protein, Carbs, and Fats are the macronutrients measured in grams (g)

To calculate the total caloric intake, multiply the grams of each macronutrient by its respective caloric value (4 for protein and carbs, 9 for fats), then sum them up.

What is Macro Calculation?

Macro calculation refers to the process of determining the amounts of macronutrients—protein, carbohydrates, and fats—that you need to consume to reach your fitness goals. Whether you’re aiming to lose weight, build muscle, or maintain your current physique, proper macro calculation is essential for effective nutritional planning.

How to Calculate Daily Macros?

The following steps outline how to calculate your daily macros using the given formula.


  1. First, determine your daily caloric needs based on your weight, goal, and activity level.
  2. Next, decide on the macronutrient breakdown that suits your goal (e.g., 40% carbs, 30% protein, 30% fats for balanced nutrition).
  3. Calculate the grams of each macronutrient based on your caloric intake and chosen macro percentages.
  4. Finally, use the formula: Calories = (Protein (g) * 4) + (Carbs (g) * 4) + (Fats (g) * 9) to verify your total caloric intake.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Weight = 180 lbs

Goal = Bulking

Activity Level = Moderate

Protein = 180g, Carbs = 300g, Fats = 90g
