About this calculator
Understanding your daily calorie needs is one of the most useful things you can do for your health. Whether you want to lose weight, gain muscle, or maintain your current weight, knowing your numbers makes all the difference. Our calorie calculator uses the Mifflin-St Jeor equation — the most accurate formula available — to estimate your Basal Metabolic Rate (BMR) and total daily energy expenditure (TDEE) based on your age, gender, weight, height, and activity level.
The formula, explained simply
We first calculate your BMR — the calories your body burns at complete rest just to keep you alive. For men: 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5. For women: 10 × weight (kg) + 6.25 × height (cm) − 5 × age − 161. Then we multiply your BMR by an activity factor (1.2 for sedentary up to 1.9 for very active) to get your maintenance calories. We also show calorie targets for mild weight loss, moderate weight loss, mild weight gain, and moderate weight gain.
When you would use this
Anyone starting a weight loss journey needs to know their maintenance calories. Athletes and bodybuilders calculate bulking and cutting phases. People with medical conditions track their intake under doctor guidance. Fitness enthusiasts optimize their nutrition. It is also educational — most people overestimate how many calories they burn and underestimate how many they eat.
