Calories Calculator

Calories Calculator

Our free Calories Calculator helps you estimate the number of calories your body needs daily to maintain, lose, or gain weight. By entering your gender, age, height, weight, and activity level, you can discover your BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure).

This tool is perfect for diet planning, fitness tracking, and building a healthier lifestyle.

Understanding Calories Calculator

A calories calculator estimates how many calories your body needs each day. It helps determine your BMR and TDEE, guiding you toward your weight goals.

How It Works

The calculator uses the Mifflin-St Jeor Equation to estimate BMR:

For Men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) + 5
For Women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(years) - 161

TDEE = BMR × Activity Factor

  • Sedentary (little/no exercise): × 1.2
  • Lightly active (exercise 1–3 days/week): × 1.375
  • Moderately active (exercise 3–5 days/week): × 1.55
  • Very active (hard exercise 6–7 days/week): × 1.725
  • Extra active (intense exercise/physical job): × 1.9

Example Calculation

Example: 30-year-old male, 70 kg, 175 cm tall, moderately active:

  • BMR = 1,655 Calories/day
  • TDEE = 2,565 Calories/day
  • Weight loss (~500 deficit): 2,065 Calories/day
  • Weight gain (~500 surplus): 3,065 Calories/day

Uses of a Calories Calculator

  • Weight Management
  • Nutrition Planning
  • Fitness Goals
  • Health Tracking

Conclusion

The Calories Calculator simplifies understanding your energy needs. By providing BMR, TDEE, and caloric targets, it helps you plan your diet and achieve your health goals.

Calories Calculator FAQ

What is a Calories Calculator?

A Calories Calculator estimates the number of calories your body needs daily to maintain, lose, or gain weight.

How accurate is a Calories Calculator?

It provides a good estimate using formulas like the Mifflin-St Jeor equation, but results can vary based on factors such as muscle mass, health conditions, and metabolism.

What is BMR and TDEE?

BMR is Basal Metabolic Rate — the calories your body needs at rest. TDEE is Total Daily Energy Expenditure — calories needed including activity.

Can I use this calculator for dieting?

Yes, it helps you plan caloric intake for weight loss, maintenance, or gain.
