Calculators

Estimate daily protein intake to support weight loss based on body weight, activity level, calorie deficit, and body composition goal.

Estimate recommended daily protein intake based on body weight, activity level, and goal. This calculator provides a practical daily target in grams using common nutrition guidelines.

Estimate your recommended daily protein intake based on body weight, activity level, and fitness goal.

Estimate recommended daily protein intake based on body weight, activity level, fitness goal, and age group. This calculator provides a practical daily protein target in grams using commonly used sports nutrition multipliers.

Estimate daily protein needs based on body weight, activity level, goal, and age group. This calculator returns recommended grams of protein per day using commonly used sports nutrition ranges.

Estimate daily cutting calories for a fat-loss phase using body weight, calorie maintenance level, activity, target weekly loss rate, and protein intake. This calculator produces a recommended daily calorie target for a cutting macro plan.

Estimate daily bulking calories and macronutrients based on body weight, height, age, sex, activity level, and desired calorie surplus. Uses the Mifflin-St Jeor equation to estimate maintenance calories, then adds a surplus and splits calories into protein, fat, and carbohydrates for a lean bulk target.

Estimate daily bodybuilding macros in grams based on body weight, calorie target, training goal, and protein/fat preferences. The calculator assigns protein and fat first, then fills remaining calories with carbohydrates.

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

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

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

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

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.

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

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.

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

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.

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 (TDEE) using the Mifflin-St Jeor equation adjusted by activity level.

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.
