Walking is one of the most accessible and sustainable forms of movement, but the number of calories it burns varies widely depending on your body weight, pace, and terrain. This walk calories per mile calculator turns those variables into a clear estimate, so you can plan walking workouts, track daily walking goals, or simply satisfy your curiosity about a favorite stroll.
Using established MET (metabolic equivalent) values from exercise science, the tool estimates calories burned per mile and scales the result to the total distance you enter. It accounts for speed from a gentle 2 mph amble to a brisk 4 mph walk, plus terrain factors for grass, hills, or backpacking. Whether you’re new to gentle movement or a seasoned hiker, this calculator gives you a practical number you can use right away.

How to Use This Calculator
All you need is your body weight and an honest sense of your walking pace. Start by entering your weight in kilograms or pounds, then choose the pace description that best matches your typical walk. The calculator uses the pace to determine both the MET value and the minutes per mile, which are the two key inputs in the calorie formula. If you plan to walk more than one mile, enter the total distance in the distance field; the tool will scale the result. Terrain is optional but worth including: a soft trail, rolling hills, or a loaded backpack can raise calorie burn by 8–35%. After you click Calculate Calories, you'll see calories per mile, total calories, total walking time, and calories per kilometer.
How the Walking Calorie Formula Works
The estimate is based on the standard metabolic equivalent, or MET, method used in exercise physiology. MET is a ratio of how much energy an activity requires compared with sitting at rest, which is defined as 1 MET. The Compendium of Physical Activities assigns walking at different speeds MET values from about 2.8 for a very slow 2 mph pace up to 5.0 for a very brisk 4 mph pace. The formula for calories per minute is:
The 3.5 represents oxygen consumption at rest in milliliters per kilogram per minute, and 200 converts those units into calories burned per minute.
Once you know calories per minute, you multiply by the minutes it takes to walk one mile. Minutes per mile are simply 60 divided by walking speed in miles per hour. So the full calculation for calories per mile becomes:
Terrain changes are handled with a multiplier: 1.08 for soft surfaces, 1.18 for gentle hills, and 1.35 for hiking with a backpack. These figures are reasonable adjustments based on the additional muscular effort and vertical work required, though your personal terrain effort may vary.
Reference: MET Values by Walking Pace
The table below shows the MET values used by this calculator for flat, paved walking, along with the estimated calories per mile for a 70 kg adult.
| Pace description | Speed (mph) | MET | Approx. kcal/mile for 70 kg |
|---|---|---|---|
| Very slow | 2.0 | 2.8 | 103 |
| Leisurely | 2.5 | 3.0 | 88 |
| Moderate | 3.0 | 3.5 | 86 |
| Brisk | 3.5 | 4.3 | 90 |
| Very brisk | 4.0 | 5.0 | 92 |
Notice that calories per mile stay in a relatively narrow band across speeds for the same person. Going faster burns more per minute, but you spend fewer minutes covering the mile, so the per-mile total changes less than you might expect. The bigger difference is per hour of walking: a faster pace burns noticeably more calories in the same amount of time.
Worked Example
Weight in kg = 75
Adjusted MET = 4.3 × 1.18 = 5.07
Calories per minute = 5.07 × 3.5 × 75 ÷ 200 = 6.65 kcal/min
Minutes per mile = 60 ÷ 3.5 = 17.1 min
Calories per mile = 6.65 × 17.1 = 113.7 kcal
Total calories = 113.7 × 2 = 227.4 kcal
Total time = 34.3 minutes
This matches the general rule of thumb that a 150–160 lb person walking at a moderate clip burns roughly 100–120 calories per mile, with hills and extra weight pushing the number toward the higher end.
Factors That Affect Accuracy
The calculator gives a solid estimate, not a laboratory measurement. Actual calorie burn is influenced by body composition, fitness level, walking economy, stride mechanics, elevation gain, uneven surfaces, weather, and even the weight of the shoes you wear. Muscular people burn slightly more at rest and during activity because muscle tissue is metabolically active. People who are well-trained may walk more efficiently and burn a little less than the MET estimate for the same speed. If you are using the result to guide nutrition, treat it as a starting point and adjust based on how your body responds over several weeks.
If you regularly walk at a very relaxed, recovery-day pace, check our light-intensity walking calculator for estimates tailored to that gentler effort.
Frequently Asked Questions
How many calories does walking one mile burn? For most adults, one mile of walking at a moderate pace burns roughly 80–120 calories. The exact number depends mainly on body weight and pace. A 60 kg person will be closer to 75 calories per mile, while a 100 kg person may burn about 125 calories per mile on flat ground.
Does walking speed really matter for calories per mile? Less than many people think when the comparison is per mile, because faster walking means fewer minutes on the road. Per hour, however, speed matters more: walking at 4 mph can burn about 40–50% more calories per hour than walking at 2 mph for the same person.
What is a MET value? MET stands for metabolic equivalent and describes how many times more energy an activity uses than resting. Sitting quietly is about 1 MET. Walking at 3 mph is about 3.5 METs, meaning it uses roughly 3.5 times the energy of rest. The MET values used here come from the Compendium of Physical Activities, a widely used research reference in exercise science.
Can I use this for running? No. Running has a different energy cost and typically requires higher MET values even at the same speed, because of the added vertical oscillation and impact. Use a running calorie calculator or your running app instead.
How does incline affect the result? The terrain multiplier partly accounts for hills, but a steep sustained grade can raise calorie burn more than the 18% hill adjustment used here. If you are hiking a mountain trail with serious elevation gain, expect higher burn than the result shows.
