Walking Calorie Calculator

A 155 lb person walking for 30 minutes at 3 mph burns about 129 calories. This walking calorie calculator estimates the calories you burn from your weight, walking speed, and time on your feet. It uses MET values from the Compendium of Physical Activities, the same reference researchers use, so a brisk 4.5 mph walk scores exactly twice the burn rate of a slow 2.5 mph stroll.

Quick answer

Calories burned depend on three things, your body weight, your walking speed, and how long you walk.

What this tells you

  • Calories burned depend on three things, your body weight, your walking speed, and how long you walk.
  • Each speed has a MET value, a multiple of resting energy use. Walking at 3 mph is 3.5 METs, meaning 3.5 times the calories you burn sitting still.
  • The formula is calories per minute = MET x 3.5 x weight in kg / 200.
  • Heavier people burn more calories at the same speed because moving more mass takes more energy.

How to Use

  1. 1Enter your body weight and pick pounds or kilograms.
  2. 2Enter how many minutes you walked or plan to walk.
  3. 3Choose your walking speed. If you are not sure, 3 mph is a typical comfortable pace.
  4. 4Read the total calories burned, plus the hourly burn rate and estimated distance.

How It Works

Formula

calories per minute = MET x 3.5 x weight (kg) / 200

MET stands for metabolic equivalent of task. Sitting quietly is 1 MET, and each walking speed has a measured MET value, from 2.8 at 2 mph up to 7.0 at 4.5 mph. Multiply the MET by 3.5, then by your weight in kilograms, and divide by 200 to get calories per minute. Multiply by your walking time for the total. For example, a 70 kg person at 3.5 METs burns 4.3 calories a minute, so a 30 minute walk burns about 129 calories.

Worked Examples

30 minute walk at 3 mph, 155 lb person

Weight155 lb
Minutes30
Speed3.0 mph
ResultAbout 129 calories

155 lb is 70.3 kg. At 3.5 METs, that is 4.3 calories a minute, times 30 minutes.

1 hour brisk walk at 4 mph, 180 lb person

Weight180 lb
Minutes60
Speed4.0 mph
ResultAbout 428 calories

180 lb is 81.6 kg. At 5.0 METs, the burn rate is about 7.1 calories a minute for 60 minutes.

45 minute stroll at 2.5 mph, 70 kg person

Weight70 kg
Minutes45
Speed2.5 mph
ResultAbout 165 calories

At 3.0 METs, a 70 kg person burns about 3.7 calories a minute, times 45 minutes.

Common mistakes

  • Using minutes of clock time instead of actual walking time. Stops at crossings or window shopping do not burn walking calories.
  • Assuming distance alone sets the burn. Two people covering 2 miles burn different amounts if their weights differ.
  • Comparing against fitness tracker numbers as if both were exact. Trackers estimate too, and wrist-based estimates often run high.

Frequently Asked Questions

A 155 lb person burns about 129 calories walking 30 minutes at 3 mph. The exact number depends on your weight, speed, and time. Heavier and faster both mean more calories.
Roughly 80 to 100 calories per mile for most adults. A 155 lb person at 3 mph burns about 86 calories per mile, while a 200 lb person burns about 111.
Yes. Walking at 4.5 mph burns 7.0 METs against 3.5 METs at 3 mph, so doubling your effort at the fast end roughly doubles your per-minute burn.
A 155 lb person at 3 mph needs about 116 minutes. At a brisk 4 mph the same person gets there in about 81 minutes.
Not exactly. 10,000 steps is roughly 5 miles for an average stride, which works out to about 400 to 500 calories for a 155 lb person. This tool measures by time and speed instead of steps.
It uses the Compendium of Physical Activities values for level walking, from 2.8 METs at 2 mph up to 7.0 METs at 4.5 mph.
It estimates walking calorie calculator outputs using the visible inputs and formula assumptions on this page.
