Walking Calories Calculator
A 70 kg person walking at a moderate 3 mph burns about 129 kcal in 30 minutes — roughly 4.3 kcal per minute. Speeding up to a brisk 4 mph raises that to about 158 kcal for the same half hour. Weight and pace are the two inputs that move the number most.
What is walking calories calculator?
Walking is the most accessible form of exercise and the one most likely to be sustained long term. Its calorie cost is modest per minute but adds up because people do it for longer.
Pace matters more than most people expect. Moving from a stroll to a brisk walk raises the MET value by around 50%, which roughly halves the time needed to burn the same calories.
MET values used
| Activity intensity | MET |
|---|---|
| Slow walk, 2.0 mph | 2.8 |
| Moderate walk, 3.0 mph | 3.5 |
| Brisk walk, 4.0 mph | 4.3 |
| Very brisk, 4.5 mph | 4.8 |
| Hill walking, 5% grade | 5.3 |
| Race walking | 6.5 |
How calories burned are calculated
Every activity has a MET value — a metabolic equivalent where 1 MET is the energy you use sitting still. This calculator uses the ACSM metabolic equation, which converts a MET value and your body weight into a calorie burn rate. MET values come from the Compendium of Physical Activities, a standard reference used in exercise research. Pick the intensity that matches what you actually did; the table below shows every option and its MET value.
kcal per minute = MET × 3.5 × body weight (kg) ÷ 200
Total kcal = kcal per minute × duration (minutes)Source: ACSM metabolic equation; MET values from the Compendium of Physical Activities.
How to use this calculator
- Choose metric (kg) or imperial (lb).
- Enter your body weight.
- Enter how long you exercised, in minutes.
- Select the intensity that best matches your effort — each option shows its MET value.
- Read your total burn, the per-minute rate, and the equivalent time walking.
Frequently asked questions
How many calories does 10,000 steps burn?
For a 70 kg person at an average pace, around 350 kcal. Heavier people burn more per step and lighter people less — this calculator scales by weight.
Is walking enough for weight loss?
It can be, but calorie intake matters more than the walking itself. A daily 30-minute brisk walk adds roughly 150 kcal of expenditure, which is meaningful over months when eating stays constant.
Does carrying a backpack help?
Yes. Extra load raises the metabolic cost, roughly in line with the added weight. Hill walking with a pack can reach MET 7 or higher.
Why do fitness trackers disagree with this?
Trackers add heart rate and step cadence data. Estimates from motion alone, like this one, typically differ from a tracker by 10–30%.
