Walking Calorie Calculator

It depends heavily on body weight and speed. A 70 kg person walking at 3 mph for 30 minutes burns approximately 120-130 kcal gross. At 4 mph the same 30 minutes burns approximately 175-185 kcal. A 90 kg person at 3 mph burns approximately 155-165 kcal for the same duration.

Running burns more calories per minute but roughly similar calories per mile (distance basis) compared to walking, because runners cover the same distance in less time at a higher MET. For a given time budget, running burns significantly more calories. For a given distance, the difference is smaller than most people expect.

Substantially. Research shows that a 5% incline at 3.5 mph increases energy cost by approximately 30% compared to level walking. At 10% grade the increase is 50-75%. Walking on a treadmill at a 1-2% incline is commonly recommended to better replicate outdoor energy expenditure, which includes wind resistance and natural terrain variation.

Any walking pace above sedentary delivers metabolic and cardiovascular benefits compared to sitting. However, research consistently shows that faster walking (above 3 mph / 4.8 km/h) is associated with greater reductions in cardiovascular disease risk and all-cause mortality compared to slow walking, even when total steps are similar. Brisk walking that raises your heart rate modestly appears to be the sweet spot for maximizing health return on time invested.
