The MET method uses only your weight, walking speed, and time — age and gender are not needed for this calculation.
Your results
Estimates based on MET values from the Compendium of Physical Activities. Incline, terrain, and body composition can shift the real number by roughly 10–20%. The step count assumes about 2,000 steps per mile — your stride varies, so treat it as an estimate. See the guide below the calculator for how to use your number.
How Walking Burns Calories
Walking is the most underrated exercise there is. It needs no gym, no equipment, and no recovery days — yet a brisk daily walk burns a meaningful number of calories, and over weeks and months that adds up to real weight change.
The calories you burn on a walk depend on three things: how much you weigh, how fast you walk, and how long you walk. A heavier person burns more per mile than a lighter person covering the same ground, because there is simply more body to move. A faster walk burns more per minute than a stroll, because your muscles work harder. And time is the multiplier: twice the walk, twice the burn.
Our calculator above puts those three together. Enter your weight, the distance you walked, and how long it took, and it works out your calories burned, your pace, your calories per mile and per kilometer, and a rough step count. Nothing is stored or sent anywhere — the math runs entirely in your browser.
The MET Method
The calculator uses the MET method, the standard approach in exercise science. One MET is the energy you burn at rest. An activity rated at 3.5 METs burns three and a half times that resting rate. So the formula is simple:
Calories = MET × weight (kg) × duration (hours)
The MET value for walking depends on speed, using approximate values from the Compendium of Physical Activities:
| Walking speed | MET value |
|---|---|
| 2.0 mph (slow stroll) | 2.8 |
| 3.0 mph (moderate pace) | 3.5 |
| 4.0 mph (brisk pace) | 5.0 |
| 5.0 mph (very brisk) | 8.3 |
For speeds between these points, the calculator interpolates in a straight line — so 3.5 mph lands halfway between 3.5 and 5.0 METs. Below 2.0 mph it uses 2.8, and above 5.0 mph it keeps 8.3 but warns you that you are approaching running pace, where this method gets rough.
Note that this method needs only weight, speed, and time. Age and gender do not enter the equation, which is why the calculator does not ask for them — they matter for your daily calorie needs, but not for the cost of one walk.
A Worked Example
Take an 80 kg person who walks 3 miles in 60 minutes. That is exactly 3.0 mph, so the MET value is 3.5. Multiply 3.5 × 80 kg × 1 hour and you get 280 calories.
The same walk gives a pace of 20 minutes per mile (60 minutes ÷ 3 miles) and about 93 calories per mile. The step estimate is roughly 6,000 steps, assuming about 2,000 steps per mile — a reasonable average, though your stride length moves this up or down.
Try the same walk at a brisker 4 mph: the MET value jumps to 5.0, so the same 80 kg person burns 400 calories in the same hour. Speed matters more than most walkers expect — that is why the calculator derives your speed from your distance and time rather than asking you to guess it.
What Changes the Number
Weight. The single biggest factor. A 100 kg walker burns about 25 percent more than an 80 kg walker on the same route at the same speed. As you lose weight, the same walk burns fewer calories — one reason weight loss slows over time.
Speed. As the table shows, MET values climb steeply with pace. The jump from 4 to 5 mph nearly doubles the per-minute burn. Brisk walking is genuinely a different workout from strolling.
Incline and terrain. Hills, sand, snow, and rough trails all raise the cost, sometimes a lot. A hilly route can burn 20 percent more than the same distance on flat pavement. The calculator assumes flat, even ground, so treat hilly walks as burning more than the number shown.
Fitness and body composition. Fitter people move slightly more efficiently, and muscle burns more than fat even at rest. These effects are modest — roughly 10 to 20 percent either way — which is why the calculator’s note gives that range rather than pretending to be exact.
Walking for Weight Loss
Walking works for weight loss precisely because it is easy to repeat. A daily 45-minute brisk walk burns roughly 200–300 calories for most adults — enough, over a month, to account for about a pound of fat, without any dieting at all. Pair it with eating at or slightly below your maintenance calories (our TDEE calculator can work that number out) and the effect compounds.
Three habits make it stick: walk at a pace where you can talk but not sing, build the distance gradually rather than jumping to long walks in week one, and track the weekly trend — same route, same effort, watching your pace improve — instead of obsessing over any single day’s number.
Frequently Asked Questions
1. How many calories do I burn walking a mile?
It depends on your weight and speed, but a useful rule of thumb is about 80–100 calories per mile for most adults at a moderate pace. A heavier walker or a brisker pace pushes it higher; the calculator gives you your own figure from your weight and speed.
2. Is walking enough exercise to lose weight?
Yes, if it is regular and brisk. A daily brisk walk of 45–60 minutes burns enough to matter, especially combined with sensible eating. It will not match running for calories per minute, but it beats running for consistency — and consistency is what actually produces weight loss.
3. Why does the calculator not ask for my age or gender?
Because the MET formula for a single walk uses only weight, speed, and duration. Age and gender matter for your total daily calorie needs, which is a different calculation — see our TDEE calculator for that.
4. How accurate is the step estimate?
It is a rough guide. The calculator assumes about 2,000 steps per mile, which is average for adults, but stride length varies with height and pace. A fitness tracker or phone step counter will be more accurate for your own stride.
5. Do hills really burn that many more calories?
Yes. Walking uphill raises the effort sharply — a steep hill can nearly double the per-minute cost while you are on it. Over a whole hilly route, expect roughly 10–20 percent more than the flat-ground figure the calculator shows.
6. How often should I walk to see results?
Aim for most days of the week, building toward 150 minutes of brisk walking weekly — the widely recommended minimum for general health. For weight loss, more helps, but start where you are and add ten minutes a week rather than burning out in the first fortnight.
