Walking Calories Calculator
Walking is one of the most accessible forms of calorie burn: no equipment, no special location, no cost. The calories you burn depend on 3 factors: your weight, your speed, and the terrain slope. This calculator applies the Compendium of Physical Activities (Ainsworth 2011) — the world reference for METs — and adjusts for uphills and downhills. It also shows the result in food equivalents for reference.
When to use this calculator
- Estimate the calorie burn of your daily walk
- Plan activity to create a calorie deficit for weight loss
- Compare the energy cost of walking vs. jogging
- See how many calories you burn uphill or climbing stairs
- Justify an extra dessert portion after a walk
Step-by-step example
- 65 kg (143 lb) woman walks 5 km in 60 minutes (5 km/h) on flat terrain.
- MET for 5 km/h = 4.3 (vigorous).
- Time = 1 h.
- Calories = MET × weight × hours = 4.3 × 65 × 1 = 279.5 kcal.
- Steps = 5,000 m / 0.7 m per stride ≈ 7,143 steps.
- Equivalent: ≈ 2.7 bananas or ≈ 1.4 candy bars.
How it works
2 min readThe Formula (based on METs)
Calories = MET × weight (kg) × time (h)The MET (Metabolic Equivalent) is the energy cost of an activity relative to rest. 1 MET ≈ 1 kcal/kg/h (basal consumption seated). A 4-MET activity requires 4x more energy than sitting.
MET Table for Walking
| Speed | km/h | mph | MET | Intensity |
|---|---|---|---|---|
| Slow stroll | 2.5 | 1.6 | 2.0 | Very slow |
| Casual walk | 3.5 | 2.2 | 2.8 | Slow |
| Normal | 4.5 | 2.8 | 3.5 | Moderate |
| Vigorous | 5.2 | 3.2 | 4.3 | Brisk walking |
| Very vigorous | 6.0 | 3.7 | 5.0 | Fast march |
| Race walking | 6.8 | 4.2 | 7.0 | Nearly jogging |
| Slow run | 7.5+ | 4.7+ | 8.3 | Jogging |
Slope Adjustment
Walking uphill significantly increases burn: approximately +0.6 MET per 1% incline. For example, walking at 5 km/h flat = 4.3 MET; on an 8% uphill it rises to 4.3 + (8 × 0.6) = 9.1 MET (more than double).
On gentle downhills (up to -10%), burn drops slightly. On very steep downhills (> -10%), it drops more, though there's an eccentric braking component.

How Many Steps to Burn 100 kcal?
For a 70 kg (154 lb) person walking at normal speed:
The famous goal of 10,000 daily steps doesn't come from scientific evidence but from a 1965 Japanese marketing campaign for the 'manpo-kei' pedometer ('10,000-step meter'). Modern studies suggest that 7,500 steps already provide nearly equivalent cardiovascular benefits.
Walking to Lose Weight: Does It Work?
Yes, with realistic numbers. To lose 1 kg of fat you need to create a deficit of ~7,700 kcal. Walking 1 h daily at normal pace (300 kcal) takes ~26 days — as long as you don't compensate by eating more, which is very common. Walking is excellent as a complement to a nutritional plan, not as the only strategy.
Long-term, the big benefits of walking are cardiovascular: 30 min/day reduces all-cause mortality by ~30%.
Frequently asked questions
How many calories do I burn if I walk 1 km?
A 70 kg (154 lb) person burns ~50–60 kcal per km walking at normal speed. Simple rule: calories per km ≈ weight × 0.7 (with weight in kg). On hills or fast walks the value rises. Distance matters more than speed for total burn.
Is it better to walk fast or for longer?
For total calorie burn, what matters most is total time × intensity. 1 h at 5 km/h ≈ 30 min at 8 km/h. For cardiovascular health improvement, higher intensity has extra benefits (improves VO2max, insulin sensitivity). But walking slowly for a long time is also very healthy.
How do I know what speed I walk at?
A normal walk is usually 4–5 km/h. To measure: 1) Use your phone or watch GPS. 2) Or time yourself: 1 km in 12 min = 5 km/h, in 10 min = 6 km/h. Talk test: if you can speak full sentences but not sing, moderate intensity (~5 km/h). If only short phrases, vigorous (~6+ km/h).
Are app calorie counts reliable?
Apps like Apple Health, Google Fit, Strava, or Garmin are reasonably reliable (±10–20%). They over- or underestimate based on configured weight, terrain, sensors. Manual MET calculation (like this calculator) is similar. Use them as general reference, not exact measurement.
Do I burn more climbing stairs?
Yes — much more. Climbing stairs is ~8 MET (vs. 3.5 MET normal walking), or 2.3 times more calories per minute. Descending is ~3.5 MET. That's why a couple of flights of stairs a day equals a short walk and is very effective if you're short on time.
Is walking good aerobic exercise?
Yes, especially at a vigorous pace (5+ km/h). It meets the WHO guidelines of 150 min/week of moderate activity. Improves cardiovascular capacity, lowers blood pressure, improves glucose, strengthens bones, and reduces dementia risk. The big advantage: very low impact, virtually no injuries.
Does walking burn fat or carbs?
At low intensity (< 60% max HR) the body uses proportionally more fat as fuel. At high intensity it uses more carbs. But what matters for weight loss is total caloric balance, not the fuel of the moment. A vigorous walk burns more total calories and more absolute fat than a slow walk.
What if I walk with a weighted vest?
Carrying weight increases calorie burn ~10% per 5 kg (11 lb) added at normal speed. A 10 kg (22 lb) vest in a 60-min walk raises kcal from ~280 to ~340. However, heavy weights increase joint load: start with 5 kg (11 lb) and build up gradually.
