Enter your weight, walking speed, duration, and optional slope to find out how many calories you burn walking. Get back your total calories burned, estimated weight loss, and a breakdown by effort level — all based on MET values used in exercise science.

The number of calories burned walking depends on your weight, speed, duration, and terrain slope. On average, a 70 kg person burns roughly 200–300 kcal during a 30-minute brisk walk on flat ground. Heavier individuals and steeper inclines significantly increase calorie expenditure.
Walking uphill dramatically increases calorie burn — each additional percentage of incline raises your metabolic equivalent (MET) and therefore energy output. A 5% uphill grade can increase calories burned by 30–50% compared to flat terrain. Downhill walking burns slightly fewer calories than flat walking.
10,000 steps is roughly 7–8 km for most people. At a moderate pace, a 70 kg person burns approximately 300–400 kcal walking 10,000 steps. The exact number depends on your stride length, weight, and speed.
A 70 kg person walking at a brisk pace (5.6 km/h) for one hour burns approximately 350–420 kcal. Walking faster, carrying weight, or choosing an inclined route will increase this figure. Lighter individuals will burn somewhat less, heavier individuals more.
Research suggests that 7,000–8,000 steps per day is associated with significant health benefits, including reduced cardiovascular risk and improved mood. The 10,000-step target is a useful motivational goal but not a strict medical requirement — any consistent walking habit is beneficial.
This calculator uses MET (Metabolic Equivalent of Task) values assigned to different walking speeds and slope grades. The formula is: Calories = MET × weight (kg) × duration (hours). MET values for walking range from about 2.5 for a slow stroll to over 5 for a steep uphill power walk.
To lose approximately 0.5 kg of fat, you need a calorie deficit of roughly 3,500 kcal. Walking 30 minutes a day at a brisk pace burns around 150–250 kcal depending on your weight. Consistently walking 5 days a week could contribute to losing about 0.5 kg per month from walking alone, assuming diet remains constant.
Walking barefoot can slightly increase muscle activation in the feet and lower legs, but the calorie difference compared to wearing shoes is negligible for most people. The terrain, pace, and your body weight have a far greater impact on total calorie burn than footwear choice.
