Calorie Calculator – Find Your Daily Calorie Needs

This Calorie Calculator is a very beneficial tool designed to help to estimate just how many calories your body needs each day to maintain, lose, or gain weight. You can find your daily calorie requirements by entering a few simple details such as age, gender, height, weight, you will get customized calorie suggestions that fit your fitness and health goals.

To have good health you need to understand how many calories your body needs, which is a very important step. Either your goal is weight loss, muscle gain, or only maintaining your current figure, understanding how many calories you burn day by day enables you to make better choices about your diet and exercise routine.

How this Calorie Calculator Works

This calorie calculator uses three of the most accurate and recognized scientific formulas to estimate your Basal Metabolic Rate (BMR) the number of calories your body burns while resting and then regulates it based on your physical activity level that determines your Total Daily Energy Expenditure (TDEE).

1. Mifflin-St Jeor Equation

The Mifflin-St Jeor formula is one of the most used equations for calculating calorie needs. It considers your height, weight, age and gender to provide you with reliable results. It is highly recommended for people who want a general tracking to estimate their daily calorie requirements.

2. Harris-Benedict Equation

The Harris-Benedict formula is classic and most well-known method that estimates and determines BMR and adjusts it to your physical activity level. Although it is slightly less accurate than Mifflin-St Jeor for modern lifestyles, it’s an option for those seeking a quick and balanced estimate of their daily calorie expenditure.

3. Katch-McArdle Formula

The Katch-McArdle formula is the most precise calorie estimation for people who know their body fat percentage. Like other formulas, which use total body weight, this formula focuses on lean body mass (LBM) your total weight minus fat mass. It means your results are customized that reflect how much muscle and tissue you have, which significantly affects metabolism.

Formula:
BMR = 370 + (21.6 × Lean Body Mass in kg)

This method is mainly useful for athletes, fitness enthusiasts, and individuals who track their body mass composition daily.

Activity Levels

Once your BMR is calculated, the Calorie Calculator multiplies it by an activity multiplier to estimate your Total Daily Energy Expenditure (TDEE) the total calories you burn each day.

Activity Levels
Activity Level Description Multiplier
SedentaryLittle or no exerciseBMR × 1.2
Lightly ActiveLight exercise 1–3 days/weekBMR × 1.375
Moderately ActiveModerate exercise 3–5 days/weekBMR × 1.55
Very ActiveIntense exercise 6–7 days/weekBMR × 1.725
Extra ActiveVery intense exercise or physical jobBMR × 1.9

Your TDEE gives you with the number of calories you should consume daily to maintain your current weight. To lose weight, eat slightly below this number. To gain weight, eat slightly above it by adjusting your calorie intake appropriately.

Understanding Your Results

Goal – Adjustment – Example
GoalAdjustmentExample
Maintain WeightEat at TDEEIf TDEE = 2,200 kcal/day → consume 2,200 kcal/day
Lose Weight10–20% calorie deficitEat around 1,800–2,000 kcal/day
Gain Weight10–20% calorie surplusEat around 2,400–2,600 kcal/day

While calorie tracking is useful, maintaining nutritional quality matters too. Focus on whole foods, lean proteins, healthy fats, and complex carbs to support your overall well-being.
