How Many Calories Do You Burn Walking a Mile? (Calculator)
The calories you burn walking a mile are about 92 calories for an adult weighing 75 kg (≈165 lb). This assumes a normal walking pace of about 3 mph, taking roughly 20 minutes to cover the mile. The figure refers to total (gross) energy used while walking, including baseline energy use.
Calories per mile rise or fall in proportion to body weight. Walking faster or slower than a normal pace usually increases calorie use slightly.
Use the calculator to estimate calories burned for your own weight and walking style. Because this is a distance-based activity, calorie estimates are reported as total calories per mile rather than activity-only calories above resting metabolism.
Calories Per Mile at Different Body Weights
Body weight matters more than most people expect. Heavy people use more calories to walk the same mile (1.61 km) as lighter people.
How many calories do you burn walking a mile at 200 pounds?
A 200 lb adult burns about 112 calories walking one mile at a normal pace. Because calorie use rises in proportion with body weight, a heavier adult burns more energy to cover the same distance.
How many calories do you burn walking a mile at 300 pounds?
A 300 lb adult burns about 168 calories walking one mile at a normal pace. Because 300 lb is a large body weight, the energy required to move that mass over a mile is much higher than for a lighter adult. Calorie use per mile rises almost directly with body weight.
Methodology
We calculated calorie estimates using metabolic equivalent (MET) values derived from the Compendium of Physical Activities, a research reference that standardises the energy cost of everyday movement. If you want to understand what a MET value represents and why it determines calories burned, see our guide to how MET values are used in calorie calculators.
Our example figures are based on a 75 kg (≈165 lb) adult, and the calculator scales results directly with body weight. The calculator reports total calories expended for the distance walked rather than activity calories above resting metabolism.
The Compendium reports walking activities as speed ranges rather than exact speeds. To model specific situations such as a 20-minute mile or a slow stroll, we selected realistic points within those ranges and adjusted the MET values slightly to match the chosen pace.
These figures are intended to give practical, real-world estimates for comparison between walking styles and body weights, not laboratory-precision measurements.
Calories Burned When You Walk Faster or Slower
Most people naturally settle into a comfortable walking pace without thinking about it. That pace is efficient — it lets you cover distance using relatively little effort.
When you walk slowly you cover less ground in the same amount of time, so total energy used over the day can be modest. Gradual weight gain is common when daily movement is limited and activity levels stay low for long periods.
How many calories do you burn walking a mile in 20 minutes?
Walking a mile in about 20 minutes corresponds to a normal walking pace of roughly 3 mph. A 75 kg (165 lb) adult burns about 92 calories walking a mile at this speed.
An early laboratory study by H. J. Ralston (1958) measured oxygen consumption while adults walked at controlled speeds and found that energy used per distance is lowest at about 74 meters per minute. That equals roughly 2.76 mph, very close to a 20-minute mile pace (3 mph). Humans naturally settle near this speed because it minimises energy used to cover a distance, which is why a normal walking pace is treated as the baseline in this calculator.
How many calories do you burn walking a mile in 30 minutes?
Walking a mile in about 30 minutes is a slower pace near 2 mph. A 75 kg (165 lb) adult burns about 96 calories for the mile.
This slightly higher value at slower speeds surprises many people. Walking has a natural efficient pace near a comfortable walking speed. When you move slower or faster than that, the energy required per distance rises slightly.
How many calories do you burn walking an hour?
At a normal walking pace of about 3 mph, you cover roughly 3 miles in one hour. A 75 kg (165 lb) adult therefore burns about 276 total calories in that hour.
A 200 lb adult burns about 331 calories for the same hour of walking, and a 300 lb adult burns about 497 calories. The difference is mainly body weight — you are moving your mass over about three miles of distance.
Numbers like this are why regular walking is often used as a simple daily health habit rather than a formal workout. For an overview, see everyday ways to take care of your heart.
Steps in a Mile
Step counts per mile are not fixed. They depend mainly on stride length, which is influenced by height. Many guides quote about 2,000 steps per mile, but most adults actually take closer to 2,200–2,400 steps. Taller people take longer strides and need fewer steps, while shorter strides require more steps to cover the same distance.
Using the baseline 75 kg (165 lb) adult, about 92 calories per mile works out to roughly 40 calories per 1,000 steps. Heavier adults burn more per step because each step moves more body mass.
For people starting from a low activity level, even short daily walks can build tolerance and comfort over time. See our guide to getting started with regular walking for ideas.

Situations that Change Calorie Burn
Real walking is rarely perfectly steady, and the way you walk affects energy consumption.
Everyday chores can also use meaningful energy, especially when the movement is stop-start or uses the upper body. A simple comparison is our leaf blowing vs raking calories burned calculator.
Walking the dog
Walking the dog often burns more calories per mile than a steady walk. Although your overall speed is slower, the movement is less efficient.
A 75 kg (165 lb) adult uses about 150 calories to cover a mile while walking a dog. You repeatedly stop and start, hold the dog back, adjust the leash, and change direction.
Terrain
Walking on sand, grass, or uneven ground increases calorie use compared with a flat hard surface. Your muscles must stabilise the body and push off a less stable surface.
For a 75 kg (165 lb) adult, a normal mile uses about 92 total calories, but walking the same mile on sand or uneven ground rises to about 112 calories.
Walking backwards
Walking backwards uses more energy than normal walking over the same distance because the movement is unfamiliar and requires more balance control.
For a 75 kg (165 lb) adult, a mile of backwards walking uses about 127 calories compared with about 92 calories for a normal walk.
