Calorie Calculator

This all-in-one nutrition calculator computes your BMR, TDEE (maintenance calories), goal-adjusted daily target, and full macro split — protein, carbohydrates, and fat — with an interactive pie chart. No need to jump between separate TDEE, calorie, and macro tools.

Uses the Mifflin-St Jeor equation multiplied by your activity level. Choose lose weight (−20%), maintain, or build muscle (+15%) and get instant gram targets for each macronutrient.

High engagement health content: users return monthly to adjust calories as weight changes. Pair results with our dedicated macro calculator for fine-tuning protein intake for strength training or endurance sports.

Typical output for a 70 kg, moderately active adult: BMR around 1,600 kcal, TDEE near 2,500 kcal, with roughly 140 g protein, 250 g carbs, and 70 g fat at maintenance. Your numbers shift with age, sex, height, and activity — enter yours for a personalized plan.
