Estimated with the ACSM walking equation. Step length is averaged by sex, and results are most reliable at a steady pace of 3 to 6 km/h (2 to 4 mph). Weight lost is worked out at 7,700 kcal per kg (3,500 kcal per lb). Real fat loss also depends on your diet.
How Many Calories Does Walking Burn?
Walking is the easiest exercise to start and keep doing, but most people have no idea how much energy it really uses. The answer depends mainly on three things: how much you weigh, how fast you walk, and how steep the ground is. The calculator above takes all three into account, and this guide explains how to read the result and what to do with it.
The short answer: a person weighing 70 kg (154 lb) who walks at a normal pace of 5 km/h (3.1 mph) on flat ground burns about 250 calories per hour. As a rough rule, that is about 3.5 calories per kilogram of body weight per hour. Walk faster, walk uphill or weigh more, and the number goes up.
How the walking calorie calculator works
The calculator uses the walking equation published by the American College of Sports Medicine (ACSM), which is widely used in exercise science. It estimates how much oxygen your body uses while walking, and every litre of oxygen is worth about 5 calories. That oxygen use rises with your speed and with the slope, and the total calories scale with your body weight.
You can enter your walk in whichever way you remember it:
- Distance and time, if you walked a known route.
- Distance and speed, which is useful on a treadmill.
- Speed and time, when you know your pace.
- Steps and time, if you wear a pedometer or use your phone. Your sex is used to estimate your step length, about 0.76 m for men and 0.67 m for women on average.
The result shows the calories you burned, your hourly rate, and the equivalent amount of body weight, using 7,700 calories per kilogram (3,500 per pound).
Calories burned walking: speed and weight
This table shows approximate calories burned in one hour of walking on flat ground. Find the row closest to your pace and the column closest to your weight.
| Walking speed | 55 kg (121 lb) | 70 kg (154 lb) | 85 kg (187 lb) |
|---|---|---|---|
| 3 km/h (1.9 mph), slow stroll | 140 | 179 | 217 |
| 4 km/h (2.5 mph), easy pace | 168 | 214 | 259 |
| 5 km/h (3.1 mph), normal pace | 195 | 249 | 302 |
| 6 km/h (3.7 mph), brisk walk | 223 | 284 | 344 |
Two things stand out. First, a heavier body burns more for the same walk, simply because it has more weight to move. Second, speed has a real effect: going from a stroll to a brisk walk adds around 100 calories an hour for most people.
How much does walking uphill add?
Slope is the most powerful lever you have. Here is what happens to a 70 kg person walking at 5 km/h for one hour as the incline increases.
| Slope | Calories per hour |
|---|---|
| 0% (flat) | 249 |
| 3% | 343 |
| 5% | 406 |
| 8% | 500 |
| 10% | 564 |
A 5% incline, which feels like a gentle hill or a modest treadmill setting, raises the burn by around 60% without making you walk any faster. Walking downhill burns less than flat ground, although the saving is smaller than the extra effort of climbing, so a hilly route is still better than a flat one overall.
Turning steps into distance and calories
The calculator converts steps into distance using an average step length, so 1 km is roughly 1,300 steps for a typical man and 1,500 steps for a typical woman. That means 10,000 steps is about 7.6 km for men and 6.7 km for women.
Take a 70 kg man who walks 10,000 steps at 5 km/h. That is about 91 minutes of walking and roughly 380 calories. A 60 kg woman doing 10,000 steps at the same pace walks for about 80 minutes and burns roughly 285 calories. The step count is a handy target, but the calories depend on weight and pace, so two people with the same steps can have quite different results.
Can walking help you lose weight?
Yes, but it works slowly, and it helps to know the real numbers. At 249 calories an hour, a 70 kg person would need about 31 hours of normal-pace walking to burn the equivalent of 1 kg of body fat. Walking one hour every day for a month comes to roughly 7,500 calories, or just under 1 kg.
That is not a reason to skip it. Walking is gentle on your joints, easy to repeat every day, and it adds up quietly over months. It also tends to make you more active in general and to improve your mood and sleep. For the best results, pair it with sensible eating. If you do not know how much you should be eating, our maintenance calorie calculator shows you the daily amount that keeps your weight steady.
Simple ways to burn more calories on your walks
- Pick up the pace for part of the walk. Alternate three minutes at a brisk speed with two minutes at an easy one.
- Add hills or an incline. Even a 3% treadmill slope makes a clear difference.
- Walk longer, not just harder. An extra 15 minutes a day adds up to over an hour and a half every week.
- Swing your arms and stand tall. A good posture and a natural arm swing keep your pace up without extra effort.
- Break it up. Three 10-minute walks count just as much as one 30-minute walk.
Why your watch may show a different number
Fitness watches and phone apps usually use heart rate or movement sensors, so they will rarely match a calculator exactly. Your real burn also depends on your stride, the surface you walk on, the wind, how fit you are, and whether you carry a bag. The calculator is most accurate between 3 and 6 km/h (2 to 4 mph). Use it as a reliable guide, and compare walks using the same method each time so you can see real progress.
Frequently asked questions
How many calories are in 10,000 steps?
It depends on your weight and pace, but for most adults it is somewhere between 300 and 500 calories. A 70 kg man at a normal pace burns about 380, and a lighter person burns less.
How long do I need to walk to burn 500 calories?
A 70 kg person burns about 4.1 calories a minute at 5 km/h, so 500 calories takes around two hours. At a brisk 6 km/h it takes about an hour and 45 minutes, and at 5 km/h on a 5% hill it drops to roughly 75 minutes.
Is walking on a treadmill the same as walking outside?
The calorie burn is very similar when the speed and slope are the same. Outdoors you also deal with wind, uneven ground and changing terrain, which usually makes the walk a little harder.
Does walking speed matter more than weight?
Both matter, but you can only control your speed. If you want a bigger burn from the same amount of time, walking faster or adding an incline works better than adding more minutes.
