Calories burned calculator
Choose an activity, enter how long you did it and your weight. The calculator uses MET values from the Compendium of Physical Activities.
How calories burned are calculated
A MET (metabolic equivalent) compares an activity with resting: 1 MET is the energy you use sitting quietly, and brisk walking is about 4.3 METs. Calories = MET × 3.5 × weight (kg) ÷ 200 × minutes.
These are averages for adults. Fitness level, terrain, technique and body composition change the real number, and fitness trackers often overestimate it — use the result as a guide.
Frequently asked questions
How many calories does walking 10,000 steps burn?
About 350–450 kcal for a 70 kg adult, depending on pace — 10,000 steps take roughly 80–100 minutes of walking.
Why do heavier people burn more calories?
Moving a larger body takes more energy, so the same activity burns more calories as body weight increases — that is why the formula includes your weight.
Should I eat back the calories I burn?
If you are trying to lose weight, eat back only part of them, if any: exercise estimates are approximate and easy to overestimate.
