Walking Calorie Calculator
Calculate calories burned while walking based on your weight, distance, time, and pace. Free and instant — no sign-up required.
Choose a steady walking pace from 3–6 km/h (1.9–3.7 mph). This model is not intended for running.
How This Walking Calorie Calculator Works
We estimate oxygen use with the ACSM walking equation, then convert it to calories using approximately 5 kcal per liter of oxygen. Speed and incline determine the estimate; body weight and duration scale the result.
MET = VO₂ ÷ 3.5
Total kcal = VO₂ × weight (kg) × minutes ÷ 200
Active kcal = (VO₂ − 3.5) × weight (kg) × minutes ÷ 200
Speed in the equation is meters per minute and grade is a decimal (2% = 0.02). At 70 kg, 4.8 km/h and 0% grade, 30 minutes gives about 121 total calories and 84 active calories. Total includes resting energy; active subtracts an estimated resting baseline.
The model assumes steady walking. An uphill setting applies that incline to the entire walk, not a route with both uphill and downhill sections. It does not account for wind, soft ground, loads, handrail use or individual metabolism. Results are estimates, not measurements or weight-loss predictions.
Method reference: Texas ACSM 2026 research abstracts (walking VO₂ equation and oxygen-to-calorie conversion). The commonly used shortcut MET × kg × hours is about 5% lower than the oxygen-based conversion used here. No blanket sex-based calorie adjustment is applied.
Calories Burned Walking for 15, 30 or 60 Minutes
A 70 kg (154 lb) person walking for 30 minutes at 4.8 km/h (about 3 mph) on flat ground burns an estimated 121 total calories. At the same pace, one hour gives about 242 calories.
| Weight | 15 min | 30 min | 60 min |
|---|---|---|---|
| 55 kg (121 lb) | 47 | 95 | 190 |
| 70 kg (154 lb) | 60 | 121 | 242 |
| 85 kg (187 lb) | 73 | 147 | 293 |
| 100 kg (220 lb) | 86 | 173 | 345 |
These rounded examples use the same formula as the calculator. Calculate calories for your own walking time.
Walking Calories per Kilometer and Mile
At 70 kg, 4.8 km/h and no incline, walking 1 km uses about 50 total calories (35 active). Walking 1 mile uses about 81 total calories (56 active). Distance alone is not enough: enter your weight and pace for a personal estimate.
| Distance | Time | Total kcal |
|---|---|---|
| 1 km | 12.5 min | 50 |
| 3 km | 37.5 min | 151 |
| 5 km | 62.5 min | 252 |
| 10 km | 125 min | 503 |
Calculate walking calories by distance in kilometers or miles.
Steps to Calories: What Does 10,000 Steps Burn?
For a 70 kg person who is 170 cm tall, our estimated step length is 0.706 m. At 4.8 km/h on flat ground, 10,000 steps covers about 7.1 km in 88 minutes and uses about 355 total calories (247 active). A different step length, weight or pace changes the result.
Use the steps calorie calculator with your own height and step count. If you know your measured distance, use distance mode to avoid the step-length estimate.
What Affects Your Burn
Body weight
The heavier you are, the more energy it takes to move your body, so the more calories you burn at the same pace and distance.
Walking speed
For a fixed duration, faster walking raises estimated oxygen use. For a fixed distance, it also reduces the time spent walking, so the total does not increase in the same way.
Grade and terrain
A steady uphill incline increases the oxygen-use estimate. Mixed hills and uneven surfaces cannot be represented precisely by a single grade setting.
Frequently Asked Questions
How many calories does walking 10,000 steps burn?
In this calculator, a 70 kg person who is 170 cm tall walking at 4.8 km/h on flat ground burns about 355 total kcal for 10,000 steps, including about 247 active kcal. This assumes a step length of height × 0.415; measured distance gives a more personal estimate.
How many calories does walking burn per mile?
At 70 kg and 4.8 km/h on flat ground, the estimate is about 81 total kcal per mile, including about 56 active kcal. Change the weight, speed and incline in the calculator for your own estimate.
How many calories does walking for 30 minutes burn?
At 4.8 km/h on flat ground, 30 minutes gives about 95 total kcal for 55 kg, 121 for 70 kg, 147 for 85 kg and 173 for 100 kg. These are rounded estimates from the calculator, not measured energy use.
What is the difference between total and active calories?
Total calories include an estimated resting energy cost during your walk. Active calories subtract that resting baseline. Trackers may use different definitions and assumptions, so their numbers may differ.
Can this calculator predict how much weight I will lose?
No. It estimates energy used during a walk. Weight change also depends on food intake, other activity and individual physiology, so a calorie estimate does not predict a specific amount of weight loss.
How accurate is this walking calorie calculator?
It is a model-based estimate for steady walking, not a measurement. Actual energy use varies with gait, fitness, terrain and other factors. We do not claim a fixed accuracy percentage. Use the formula and assumptions above to understand the result.
