Uses the Mifflin-St Jeor formula and a balanced 30/40/30 macro split. These are estimates — consult a professional for personalized nutrition advice.

How the Calorie Calculator works

Using your age, height, weight, and sex, the calculator estimates your Basal Metabolic Rate (BMR) with the Mifflin-St Jeor formula, then multiplies it by an activity factor to find your maintenance calories (TDEE). Choosing a goal adjusts that number up or down, and a balanced macro split is calculated from the result.

Frequently asked questions

What is TDEE?

Total Daily Energy Expenditure — the total number of calories you burn in a day, including your resting metabolism plus activity. Eating at this level maintains your current weight.

How many calories should I cut to lose weight?

A deficit of about 500 calories a day from your TDEE is a common target, producing roughly 1 pound (0.45 kg) of weight loss per week.

How are the macro targets calculated?

This calculator uses a balanced split of 30% protein, 40% carbohydrates, and 30% fat, converted to grams based on your calorie target. Individual needs vary based on goals and activity type.
