Walking Calories Burned Calculator
Find out how many calories you burn walking. Enter your weight, speed and time (or distance) and any incline, and this calculator uses the ACSM walking equation to estimate calories burned, plus an estimate of your steps.
Walking burns approximately 0.5 to 0.7 kcal per kilogram of body weight per kilometer on level ground. Walking 10,000 steps typically burns 300 to 500 kcal depending on body weight, walking speed, and gradient.
Walking Calories Burned

Walking Speeds & Energy Demands
| Walking Pace | MET Intensity | Physiological Demand |
|---|---|---|
| Slow stroll (2.5 km/h / 1.5 mph) | 2.0 MET | Light casual movement |
| Moderate walk (4.5–5.0 km/h / 3.0 mph) | 3.5 MET | ACSM metabolic walking standard |
| Brisk fitness walk (6.0 km/h / 3.7 mph) | 4.3 MET | Cardiovascular endurance aerobic pace |
| Uphill walking (5.0 km/h @ 5% grade) | 6.0+ MET | Higher muscular recruitment and caloric expenditure |

How to use Walking Calories Burned Calculator
- 1Enter your body weight in kilograms or pounds.
- 2Specify your walking duration in minutes.
- 3Enter your walking speed (average brisk walk is 4.8 to 5.5 km/h or 3.0 to 3.5 mph).
- 4Add any treadmill incline or carried backpack weight to compute gross and net calories.
The ACSM walking equation
The American College of Sports Medicine metabolic equation calculates oxygen consumption during walking (3.0 to 6.0 km/h): VO2 = (0.1 × Speed) + (1.8 × Speed × Incline) + 3.5 ml/kg/min. Each liter of oxygen consumed equates to roughly 5 kcal burned.
Impact of incline and rucking
Adding a 5% to 10% incline more than doubles the caloric expenditure of flat-ground walking by engaging posterior chain musculature and increasing cardiovascular demand.
Frequently Asked Questions
How many calories does walking 10,000 steps burn?
Often about 300 to 500 kcal, depending on weight and speed.
Does incline walking burn more calories?
Yes. Each 1% of incline adds noticeably to energy use; 10% incline can nearly double it at the same speed.
How many calories does walking 1 km burn?
Roughly 0.5 to 0.7 kcal per kg of body weight per km on flat ground.
