Calculators

Estimate daily calorie needs based on age, sex, weight, height, activity level, and goal using the Mifflin-St Jeor equation with activity and calorie adjustment factors.

Calculate what percentage of your daily calories comes from protein, carbohydrates, and fat based on grams consumed and total daily calories.

Calculate daily macronutrient grams for protein, carbohydrates, or fat based on body weight, target macro ratio, and number of meals per day.

Estimate daily calorie, protein, fat, and carbohydrate targets for weight loss using body weight, height, age, sex, activity level, and desired calorie deficit.

Estimate daily calories and macronutrients for muscle gain using body weight, training volume, activity level, and surplus size.

Estimate daily calorie, protein, carbohydrate, and fat targets for women based on age, height, weight, activity level, and goal. This calculator uses a calorie estimate adjusted for activity and goal, then returns a calorie result while encoding macro distribution logic into the overall estimate.

Estimate daily macronutrient targets based on body weight, fitness goal, activity level, and preferred protein intake.

Estimate daily macronutrient targets based on body weight, calorie goal, activity level, and nutrition goal. Calculates recommended daily grams of protein, carbohydrates, and fat from total calories using common macro split guidelines.

Estimate daily macronutrient targets in grams based on body weight, activity level, calorie goal, and preferred carbohydrate intake. The calculator uses body weight to set protein and fat baselines, then assigns remaining calories to carbohydrates.

Estimate daily calories and macronutrient targets based on body weight, activity level, and goal. Calculates daily grams of protein, fat, and carbohydrates from a calorie target using practical macro splits.

Estimate your basal metabolic rate (BMR), the number of calories your body burns at rest each day, using the Mifflin-St Jeor equation with inputs for sex, age, weight, and height.

Estimate basal metabolic rate for women using age, height, weight, and formula selection. BMR represents the calories your body needs at rest to maintain basic functions.

Calculate basal metabolic rate for men using the Mifflin-St Jeor equation based on age, weight, height, and unit system.

Estimate daily calorie needs for weight loss using basal metabolic rate, activity level, and a calorie deficit. Uses the Mifflin-St Jeor equation to estimate BMR, then calculates maintenance calories and target calories for fat loss.

Estimate total daily energy expenditure (TDEE) from your basal metabolic rate (BMR) using activity level, exercise sessions, and goal adjustment.

Estimate resting metabolic rate (RMR) using the Mifflin-St Jeor equation, adjusted for sex. Enter age, weight, height, and sex to calculate the calories your body burns at rest each day.

Estimate daily calorie needs using the Mifflin-St Jeor equation with sex, age, weight, height, and activity level. The result gives estimated maintenance calories per day.

Estimate daily calorie needs using the Harris-Benedict equation based on sex, age, weight, height, and activity level. The result shows total daily energy expenditure calories needed to maintain current weight.

Estimate basal metabolic rate using the Katch-McArdle formula based on body weight and body fat percentage, then adjust by activity level to estimate daily calorie needs.

Estimate total daily energy expenditure for a sedentary lifestyle using age, sex, weight, and height. This calculator uses the Mifflin-St Jeor BMR equation and applies a sedentary activity multiplier of 1.2.

Estimate total daily energy expenditure for active adults using the Mifflin-St Jeor BMR equation adjusted by activity level. Enter age, sex, weight, height, and training activity to estimate daily calorie needs.

Estimate your basal metabolic rate (BMR), the number of calories your body needs each day at rest, using the Mifflin-St Jeor equation with inputs for sex, age, weight, and height.

Estimate Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation adjusted by activity level.

Estimate your total daily energy expenditure (TDEE) using the Mifflin-St Jeor equation for basal metabolic rate and an activity multiplier.

Estimate total daily energy expenditure for women using age, weight, height, and activity level. Uses the Mifflin-St Jeor equation for women to calculate BMR, then applies an activity multiplier to estimate daily calorie needs.

Estimate total daily energy expenditure for men using the Mifflin-St Jeor equation and an activity multiplier.

Estimate your daily calorie target for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. This calculator estimates BMR with the Mifflin-St Jeor equation, applies an activity multiplier to find TDEE, then subtracts the calories needed to support your target rate of weight loss.

Estimate daily calories for muscle gain using age, sex, body weight, height, activity level, and training surplus. The calculator estimates BMR with the Mifflin-St Jeor equation, applies an activity multiplier to find TDEE, then adds a calorie surplus to support lean muscle gain.

Estimate total daily energy expenditure using the Katch-McArdle formula based on weight, body fat percentage, age, and activity level.

Estimate your daily calorie target for gaining weight by adding a calorie surplus to your maintenance calories based on body weight, age, sex, activity level, and desired weekly weight gain.
