BMR Calculator — Basal Metabolic Rate

Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) for weight management.

Planning estimateThe result is a planning estimate only. It does not replace professional advice or a personal review.

BMR & TDEE — The Foundation of Calorie Calculation

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest. TDEE accounts for your activity level: BMR × activity multiplier.

Mifflin-St Jeor Formula (most accurate)

  • Men: 10W + 6.25H − 5A + 5
  • Women: 10W + 6.25H − 5A − 161
  • W=kg, H=cm, A=age

💡 Useful Tips

  • For fat loss: eat 300–500 calories below TDEE.
  • For muscle gain: eat 200–300 calories above TDEE.
  • BMR decreases with age — resistance training helps maintain metabolic rate.

Frequently Asked Questions

How accurate is BMR/TDEE calculation?

These are statistical estimates. Real metabolic rates can vary by 10-15% from person to person.

What is the difference between BMR and RMR?

BMR is measured under strict lab conditions. RMR (Resting Metabolic Rate) is measured under normal rest — slightly higher, and closer to what most calculators estimate.
