Calorie Calculator
Understand your body’s needs with our precise calorie calculator.
The Formula Behind Your Results
Our calculator uses the Mifflin-St Jeor equation, widely considered a highly accurate method for estimating your Basal Metabolic Rate (BMR), or the calories your body burns at rest. Your total daily calorie needs (TDEE) are then calculated by multiplying your BMR by an activity factor.
For Men:
BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age + 5
For Women:
BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age – 161

5. Frequently Asked Questions
How accurate is this calculator?
It’s highly accurate for most people. It uses the Mifflin-St Jeor formula, which is a well-regarded standard. However, remember that it’s an estimate. Individual metabolisms can vary, so it’s best used as a strong starting point and guide.
How often should I recalculate my calorie needs?
It’s a good idea to recalculate whenever you have a significant change in your weight (e.g., a 5-10% change) or if your regular physical activity level changes dramatically for a sustained period.
Why are there different goals for weight loss and gain?
To lose weight, you need to consume fewer calories than your body burns (a calorie deficit). To gain weight (ideally muscle), you need to consume more (a calorie surplus). Our tool provides a safe and sustainable target for each goal, typically a 500-calorie deficit for loss and a 300-500 calorie surplus for gain.
Can I just focus on calories and ignore food quality?
While calorie balance is key for weight management, food quality is crucial for overall health, energy levels, and body composition. For best results, focus on hitting your calorie targets with nutrient-dense foods like lean proteins, whole grains, fruits, and vegetables.
What do BMR and TDEE mean?
BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions at rest. TDEE (Total Daily Energy Expenditure) is your BMR plus the calories you burn from all physical activity, from walking to intense exercise. Your TDEE is your “maintenance” calorie number.
