What is a Calories Burned Calculator?
A Calories Burned Calculator estimates how many calories you burn during physical activity based on the activity type, your weight, and duration. It uses MET values to provide a reliable estimate for common exercises.
How to calculate calories burned manually (the formula)
Calories burned = MET × 3.5 × weight (kg) ÷ 200 × duration (minutes). Each activity has a standard MET value. For example, jogging has a MET of 7.0, meaning it burns 7 times more energy than rest.
Example calculation
A 72 kg person jogging (MET 7.0) for 30 minutes: 7.0 × 3.5 × 72 ÷ 200 × 30 = 265 calories burned. The same person walking (MET 3.5) would burn about 132 calories.
Common mistakes
- Overestimating intensity — MET values assume a standard pace. If you walk slowly or take breaks, your actual burn may be lower than estimated.
- Ignoring body weight — A heavier person burns more calories doing the same activity. Do not use generic calorie estimates that ignore your weight.
- Double-counting activity — Your BMR already accounts for calories burned during the day. Do not add exercise calories on top of your total daily burn without adjusting your baseline.
Frequently asked questions
How are calories burned calculated?
Calories burned are calculated using the MET formula: MET × 3.5 × weight(kg) ÷ 200 × duration(minutes).
What is MET?
MET stands for Metabolic Equivalent of Task. One MET is the energy expended at rest. Higher MET values mean more intense exercise and more calories burned.
How accurate is the calories burned estimate?
The estimate is based on standard MET values and population averages. Actual burn varies based on intensity, fitness level, and individual metabolism.
Does body weight affect calories burned?
Yes, heavier individuals burn more calories performing the same activity because more energy is required to move a larger mass.
What activity burns the most calories?
High-intensity activities like running, jump rope, and swimming typically burn the most calories per minute. Duration and intensity are the key factors.
