Estimate your daily calorie target for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. This calculator uses the Mifflin-St Jeor equation to estimate basal metabolic rate, adjusts for activity, and subtracts calories based on your target rate of weight loss.

Estimate the daily calorie deficit needed to lose one pound over your chosen time frame, based on the common guideline that one pound of body fat is approximately 3,500 calories.

Estimate your weekly calorie deficit based on daily maintenance calories, daily calorie intake, exercise calories burned, and number of workout days per week.

Estimate your average daily calorie target and high-, medium-, and low-calorie days for a calorie cycling plan based on body weight, maintenance calories, weekly training days, and goal.

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

Estimate your daily cutting calories based on body weight, height, age, sex, activity level, and desired calorie deficit. Uses the Mifflin-St Jeor equation to estimate maintenance calories and then applies a cutting deficit.

Estimate daily calories for a bulking phase using body weight, height, age, sex, activity level, and desired calorie surplus. The calculation uses the Mifflin-St Jeor equation for BMR, then applies an activity multiplier and adds a bulking surplus.

Estimate daily calories needed to gain weight based on sex, age, weight, height, activity level, and desired weekly weight gain. Uses Mifflin-St Jeor BMR and adds a calorie surplus for weight gain.

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.

Estimate daily calorie intake for weight loss using age, sex, weight, height, activity level, and desired weekly weight loss. The calculation uses the Mifflin-St Jeor equation for BMR, adjusts for activity, then subtracts a calorie deficit based on target weekly weight loss.

Estimate daily calorie needs using age, sex, weight, height, activity level, and goal. This calculator uses the Mifflin-St Jeor equation to estimate basal metabolic rate, then adjusts for activity and calorie goal.

Calculate your calorie deficit percentage based on maintenance calories and target calorie intake. This helps estimate how large your daily calorie reduction is relative to your maintenance level.

Estimate your daily calorie target for weight loss based on age, sex, weight, height, activity level, and desired weekly weight loss using the Mifflin-St Jeor equation and an activity multiplier.

Estimate your daily maintenance calories using age, sex, weight, height, and activity level based on the Mifflin-St Jeor equation multiplied by an activity factor.

Estimate your daily maintenance calories using the Mifflin-St Jeor equation adjusted by activity level. This calculator estimates the calories needed per day to maintain your current weight.

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

Estimate daily calorie needs using age, sex, weight, height, and activity level based on the Mifflin-St Jeor equation multiplied by an activity factor.

Estimate daily calorie intake based on age, sex, weight, height, and activity level using a standard BMR-based calculation.

Estimate daily calorie needs using age, sex, weight, height, and activity level based on the Mifflin-St Jeor equation multiplied by an activity factor.

Estimate body mass index for older adults using height and weight, with support for metric or U.S. units. This calculator also includes an optional age input for senior context, though BMI itself is based on height and weight.

Calculate Body Mass Index (BMI) using weight in pounds and height in feet and inches. This calculator converts imperial measurements to BMI and returns your BMI value.

Calculate body mass index during pregnancy using current weight and height, with an adjustment based on trimester to estimate pre-pregnancy equivalent BMI.

Calculate body mass index before pregnancy using pre-pregnancy weight and height. BMI is commonly used to estimate weight status before conception.

Calculate the change in body mass index (BMI) between a starting weight and a current weight using height in either centimeters or inches.

Calculate the target body weight range based on height and selected BMI goals using either metric or imperial units.

Calculate the target body weight needed to reach a chosen BMI based on height. Optionally compare it with current weight to see the weight change required.

Calculate the healthy weight range for a target BMI category based on height and unit system. Uses standard BMI thresholds to estimate the minimum and maximum body weight for the selected range.

Estimate the healthy weight range based on height and target BMI category. Enter your height and choose metric or imperial units to calculate the minimum and maximum healthy body weight.

Calculate the target body weight needed to reach a chosen BMI based on height. Enter height in centimeters and a target BMI to estimate the corresponding weight in kilograms.

Calculate Body Mass Index (BMI) using weight in kilograms and height in centimeters. BMI is computed as weight divided by height in meters squared.
