Calorie Needs Calculator
Find out how many calories your body needs daily based on your weight, height, age, gender, and activity level.
✅ What is Calorie Needs or TDEE?
Your Calorie Needs, or TDEE (Total Daily Energy Expenditure), is the number of calories your body requires each day to maintain its current weight. It combines your Basal Metabolic Rate (BMR) — the calories burned at rest — with the calories burned during physical activity.
This calculator uses the Mifflin-St Jeor equation, which is one of the most accurate methods to determine BMR, then multiplies it by an activity factor to estimate TDEE.
🛠️ How to Use the Calorie Needs Calculator
Our calculator supports both metric and imperial units. It’s simple and fast:
👉 Steps:

Frequently Asked Questions (FAQs)
1. How does this differ from a BMR calculator?
A BMR calculator tells you how many calories your body burns at rest. A calorie needs calculator includes your activity level, offering a full picture of your daily energy requirements.
2. Can this help with weight loss?
Yes. By calculating how many calories you burn and creating a deficit (eating fewer calories), you can effectively lose weight over time.
3. What activity levels can I choose from?
Most calculators include sedentary, lightly active, moderately active, very active, and extra active options—so you can match it to your lifestyle.
4. Should I recalculate my needs if my weight changes?
Absolutely. As your weight, age, or activity level changes, your daily calorie needs may shift. It’s a good idea to recalculate every few weeks.
5. Is this calculator free and mobile-friendly?
Yes. It’s 100% free to use, optimized for mobile and desktop devices, and does not require any sign-up.
