🔍 What is a Calorie Calculator?
A calorie calculator is an essential tool that estimates the number of calories your body needs daily based on your age, gender, weight, height, and activity level. It helps you understand your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE)—two key values that guide your dietary planning.
At UnitXpert, we’ve built this calculator with precision and simplicity in mind. It’s fast, modern, mobile-friendly, and completely free to use.
🔢 How the Calorie Calculator Works
This calorie calculator uses the Mifflin-St Jeor Equation, widely regarded as one of the most accurate methods for determining BMR:
✅ BMR Formulas:
- Male:
BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age + 5 - Female:
BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age – 161
After calculating BMR, we multiply it by an activity multiplier to determine your TDEE:
🏃 Activity Multipliers:
| Level | Factor |
|---|---|
| Sedentary | 1.2 |
| Lightly Active | 1.375 |
| Moderately Active | 1.55 |
| Very Active | 1.725 |
| Super Active | 1.9 |
Based on your chosen goal—maintain, lose, or gain weight—your final calorie recommendation is adjusted accordingly.
