Calculate Your Daily Calorie Needs
Calculate your personalized daily calorie intake for weight loss, maintenance, or muscle gain. Free, accurate, and based on proven BMR and TDEE formulas.
Your daily calorie intake determines whether you lose weight, maintain weight, or gain muscle. Use this calculator to find your personalized calorie target based on your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
Lose 0.5-1 kg per week
Keep current weight
Gain 0.25-0.5 kg per week

Basal Metabolic Rate (BMR) is the number of calories your body burns at complete rest to maintain vital functions like breathing, circulation, and cell production. It represents 60-75% of your daily calorie expenditure.
BMR is calculated using the Mifflin-St Jeor equation, which considers your weight, height, age, and gender. Men typically have higher BMR due to more muscle mass.
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn each day, including your BMR plus all physical activities, exercise, and digestion.
TDEE = BMR × Activity Level Factor. Your activity level significantly impacts your calorie needs. An active person may burn 500-1000+ more calories than a sedentary person with the same BMR.

Calculating your daily calorie intake for weight loss involves three key steps:
A deficit of 500 calories per day leads to approximately 0.5 kg of fat loss per week, as 1 kg of body fat equals about 7,700 calories. For faster results, you can increase the deficit to 500-750 calories, but never go below your BMR or minimum safe intake levels (1200 calories for women, 1500 for men).
Building muscle requires a caloric surplus combined with progressive resistance training. Here's how to calculate your muscle gain calories:
A smaller surplus (250 calories) minimizes fat gain and is ideal for those concerned about staying lean. A larger surplus (500 calories) accelerates muscle growth but may lead to more fat gain. Beginners and those returning from a long break can often gain muscle even at maintenance calories through "newbie gains."
Your activity level multiplier is crucial for accurate calorie calculations. Here's how to choose:
Pro tip: When in doubt, start with a lower activity level. It's easier to add calories if you're losing weight too quickly than to reduce them if you're not losing weight.
The number of calories you should eat depends on your goal and personal factors:
Female, 30 years, 70 kg, 165 cm, moderate activity
Male, 25 years, 75 kg, 180 cm, very active
Creating an effective calorie deficit requires strategy and patience:
Avoid these common errors that sabotage calorie calculations:
To calculate your daily calorie intake, first calculate your Basal Metabolic Rate (BMR) using your weight, height, age, and gender. Then multiply your BMR by your activity level factor (1.2 for sedentary, 1.375 for light activity, 1.55 for moderate, 1.725 for active, or 1.9 for very active). The result is your Total Daily Energy Expenditure (TDEE), which represents your maintenance calories.
To lose weight, you should eat 300-500 calories below your maintenance calories (TDEE) for a safe weight loss of about 0.5-1 pound per week. For faster weight loss, a deficit of 500-750 calories per day can result in 1-1.5 pounds per week. Never go below 1200 calories for women or 1500 for men without medical supervision.
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest to maintain vital functions like breathing and circulation. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your activity level factor, representing the total calories you burn in a day including all activities, exercise, and digestion. TDEE is always higher than BMR.
To gain muscle, eat 250-500 calories above your maintenance calories (TDEE). This caloric surplus, combined with progressive strength training, supports muscle growth. Aim for 0.5-1 pound of weight gain per week to maximize muscle gain while minimizing fat gain. Consume adequate protein (1.6-2.2g per kg body weight) and follow a structured training program.
Choose Sedentary (1.2) if you have a desk job with little exercise, Light (1.375) for 1-3 days/week of exercise, Moderate (1.55) for 3-5 days/week, Active (1.725) for 6-7 days/week, or Very Active (1.9) for intense daily training or a physically demanding job. When uncertain, start with a lower activity level and adjust based on results.
Calorie counting is a useful tool for weight management, but it's an estimate. Individual metabolism, hormones, sleep quality, stress levels, and food quality all affect results. Use calorie calculations as a starting point and adjust based on your actual progress over 2-4 weeks. Track your weight weekly and average the results to see trends.
You don't need to eat exactly the same calories every day. What matters is your average calorie intake over the week. Some people prefer calorie cycling, eating more on training days and less on rest days, while maintaining the same weekly total. This approach can improve adherence and performance while still achieving your goals.
Recalculate your calorie intake every 5-10 kg of weight change, or every 2-3 months. As you lose weight, your BMR and TDEE decrease because there's less body mass to maintain. Similarly, if you gain muscle, your calorie needs may increase. Regular recalculation ensures your targets remain accurate and effective.
