Free Metabolism Calculator – Know Your Daily Calorie Needs!

Want to lose weight, gain muscle, or just feel more energetic? It all starts with understanding your daily calorie needs. Our Free Metabolism Calculator is the easiest way to know how much fuel your body needs—no guesswork, just clear numbers.

What Exactly Is Metabolism?

• Metabolism is how your body turns food into energy.
• It’s working 24/7—even when you’re chilling on the couch.
• Everyone’s metabolism is unique, based on:
  • Age
  • Gender
  • Height & Weight
  • Activity Level
• Your metabolism affects your weight, energy levels, and how fast your body burns calories.

How Our Free Metabolism Calculator Works

• Just enter a few quick details:
  • Age
  • Gender
  • Height
  • Weight
  • Daily activity level (from sedentary to very active)
• You’ll get:
  • BMR (Basal Metabolic Rate) – how many calories you burn at rest
  • TDEE (Total Daily Energy Expenditure) – how many calories you burn in a day with normal activity
• We also show calorie targets for:
  • Weight maintenance
  • Healthy weight loss
  • Steady weight gain

Why You Need This Calculator

• Most people underestimate or overestimate how much they should eat.
• Helps you eat just the right amount—not too little, not too much.
• Whether you’re trying to shed pounds, bulk up, or just stay fit, this tool gives you a solid starting point.
• No confusing math. No guessing. Just quick, clear results.

What Your Results Mean

• BMR = Calories your body needs to survive (if you stayed in bed all day)
• TDEE = Calories your body actually uses, considering movement and exercise
• You’ll also see:
  • Calorie intake for weight maintenance
  • Calories to safely lose weight (usually a deficit of 500–700/day)
  • Calories to gain muscle (a surplus of 250–500/day)

Tips to Naturally Boost Your Metabolism

• Eat protein with every meal (your body burns more calories digesting it)
• Stay active throughout the day—walk more, stretch, move!
• Do strength training to build lean muscle
• Get enough sleep—your metabolism slows when you’re tired
• Avoid extreme dieting or skipping meals—it can slow down your metabolism
