The Daily Calorie Intake Calculator is a free, accurate online tool designed to help you track and understand important health metrics in seconds. Just enter age, sex, weight unit, weight, height unit, height (cm), height (feet), height (inches), activity level, weight goal and instantly see basal metabolic rate (bmr). Understanding your health numbers is the first step to taking control of your wellbeing. Whether you are tracking progress, setting goals, or comparing yourself to standard ranges, getting an accurate baseline matters. This calculator uses widely accepted clinical formulas and is updated to reflect modern guidelines. Under the hood, the tool applies the standard formula: Mifflin-St Jeor Equation (BMR): Male: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 | Female: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161. Total Daily Energy Expenditure (TDEE) = BMR × Activity Factor. You can see exactly how the result is derived, which is especially useful for students, professionals, and anyone who wants to learn rather than just get an answer. CalcPlanet builds every calculator to be fast, mobile-friendly, and free, with no signup required. We test results against worked examples and reference implementations so you can rely on what you see. Enter your values above to get an instant, accurate daily calorie intake calculator result, then explore the FAQs and examples below for deeper context.

(feet * 12 + inches) * 2.54 : height))) - (5 * age) - 161)
The Mifflin-St Jeor equation estimates Basal Metabolic Rate (BMR), the calories burned at rest. This BMR is then multiplied by an activity factor to determine your Total Daily Energy Expenditure (TDEE). Adjustments are made for weight goals.
