Frequently Asked Questions
What is BMR?
BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic life functions like breathing, circulation, and cell production. It represents about 60-75% of your total daily calorie expenditure.
How accurate is this BMR calculator?
We use the Mifflin-St Jeor equation, which is considered one of the most accurate formulas. However, individual metabolic rates vary based on genetics, hormones, and body composition. Use this as a starting point and adjust based on your results.
What's the difference between BMR and TDEE?
BMR is calories burned at complete rest. TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through activity. Our calculator shows both - BMR for baseline and TDEE based on your activity level.
Is this calculator free to use?
Yes, ApexSofteck Tools's BMR Calculator is completely free. Use it unlimited times to plan your nutrition and fitness goals without any registration.
How do I use BMR for weight loss?
To lose weight, consume fewer calories than your TDEE. A 500-calorie daily deficit typically results in losing about 0.5kg (1lb) per week. Never eat below your BMR for extended periods as this can slow your metabolism.
