MinimalistHow many calories does walking burn?
Walking burns roughly 0.75 calories per kilogram of body weight for every kilometer you walk — about 55 calories per km (90 per mile) for a 75 kg (165 lb) person. Speed matters less than you’d think; distance and body weight matter most.
Below you’ll find a table of estimates, a quick rule you can do in your head, and an honest explanation of why every calorie number — including the ones on watches and apps — is an approximation.
Calories burned walking: estimates by weight and speed
These figures are for 30 minutes of walking on flat ground. They’re calculated from standard MET values (a measure of how much energy an activity uses compared with sitting still), using the common formula: calories = MET × body weight in kg × hours.
| Speed | MET | 60 kg / 132 lb | 75 kg / 165 lb | 90 kg / 198 lb |
|---|---|---|---|---|
| Slow — 3.2 km/h (2 mph) | 2.8 | ~85 | ~105 | ~125 |
| Moderate — 4.8 km/h (3 mph) | 3.5 | ~105 | ~130 | ~160 |
| Brisk — 5.6 km/h (3.5 mph) | 4.3 | ~130 | ~160 | ~195 |
| Very brisk — 6.4 km/h (4 mph) | 5.0 | ~150 | ~190 | ~225 |
Double the numbers for an hour. For other body weights, scale proportionally: someone weighing 105 kg would burn about 40% more than the 75 kg column.
A simple rule: calories per kilometer or mile
Look closely at the table and something interesting shows up. Walking faster burns more per minute, but you also cover more ground. Per kilometer, the totals stay fairly similar across normal walking speeds.
That gives you a useful shortcut:
- Metric: calories ≈ 0.75 × your weight in kg × kilometers walked
- Imperial: calories ≈ 0.55 × your weight in lb × miles walked
Some examples:
| Walker | Distance | Approximate calories |
|---|---|---|
| 60 kg | 3 km | ~135 |
| 75 kg | 5 km | ~280 |
| 90 kg | 8 km | ~540 |
| 150 lb | 2 miles | ~165 |
| 200 lb | 3 miles | ~330 |
This is why distance is such a handy number to track. If you know how far you walked and roughly what you weigh, you have a reasonable estimate. Minimalist intentionally doesn’t show a calorie figure — we’d rather show you an accurate distance than a precise-looking guess — but with your distance and this rule, you can estimate it in a few seconds.
Gross vs net calories: the part most apps skip
Your body burns calories all the time, even sitting on the couch — roughly 1 MET, or about 1 calorie per kilogram per hour. The figures above are gross calories: everything you burned during the walk, including what you’d have burned anyway.
The extra energy caused by the walk itself — the net calories — is lower. For moderate walking, subtract roughly a quarter to a third from the gross figure.
So a 75 kg person who burns about 130 gross calories in a 30-minute walk has used maybe 90–100 calories more than if they’d sat still. If you’re estimating for weight management, the net figure is the more honest one.
What makes walking burn more (or fewer) calories?
Body weight
The biggest factor. Moving a heavier body takes more energy, so the same walk burns more for a larger person.
Hills and stairs
Walking uphill raises the energy cost substantially — even a moderate incline can make a walk feel and count like a much faster one. Downhill is easier on your heart, though harder on your thigh muscles.
Terrain
Sand, snow, mud and uneven trails all take more energy than smooth pavement, because your muscles work harder to stabilize each step.
Carrying a load
A backpack, groceries or a child in a carrier all add to the work. A heavier pack makes a noticeable difference over a long walk.
Very fast walking
The “constant per kilometer” rule holds well for normal walking speeds. At very fast speeds — around 7 km/h (4.5 mph) and above — walking becomes less efficient and per-kilometer costs rise. At that point, a slow jog may actually feel easier.
Fitness and technique
Fitter, more practiced walkers tend to be a bit more efficient, but this effect is smaller than people assume. Weight, distance and terrain matter much more.
Why calorie numbers on trackers are often off
Every calorie estimate — from a watch, a treadmill, an app or a table like ours — is built on averages. Two people of the same weight can burn different amounts because of differences in muscle mass, age, body composition and walking style.
Devices that use heart rate can adjust for some of this, but heart rate is also affected by heat, caffeine, stress and sleep. Independent testing of wearables has generally found that their step and heart rate readings are reasonably good, while their calorie estimates can be off by a wide margin.
So treat any calorie number as a rough guide, useful for comparing your own walks over time, not as a precise measurement. Distance and time are far more reliable to track — and if your GPS distance looks strange, see why your GPS distance seems off.
Walking vs running: calories compared
Running burns roughly 1 calorie per kilogram per kilometer — somewhat more than walking per distance, and much more per minute because you cover ground faster. A 75 kg person running 5 km burns around 375 calories, compared with about 280 walking the same distance. Running it just takes half the time.

Putting the numbers in perspective
It’s easy to get discouraged when you see that a 30-minute walk burns about as much as a slice of bread with butter. But calories are only one part of what walking does. Its effects on heart health, blood sugar, mood, sleep and joints don’t show up in any calorie count. For those, see the benefits of walking every day.

FAQ
How many calories does walking 10,000 steps burn?
10,000 steps is roughly 7–8 km (4.5–5 miles) for most adults. Using the rule above, that’s about 300–350 calories for a 60 kg person and 400–450 for an 80 kg person, gross. Remember that many of those steps happen during normal daily activity.
Does walking faster burn more calories?
Per minute, yes. Per kilometer, only slightly, until you reach very fast walking speeds. If you have a fixed amount of time, walking faster helps; if you have a fixed distance, speed matters less.
Does walking on a treadmill burn the same as outdoors?
Close to it. Outdoor walking involves slight changes in terrain and wind, which can add a little. Setting the treadmill to a 1% incline is a common way to approximate outdoor effort.
