Calories Burned Walking Calculator

Walking is one of the most effective and accessible forms of exercise — and unlike running, it can be sustained for hours without excessive fatigue. Calorie burn from walking depends on your body weight, walking speed, distance, and terrain.

MET-based formula (most accurate): Calories = MET × Body Weight (kg) × Time (hours)

MET values for walking:

• Slow pace (2.0 mph / 3.2 km/h): MET = 2.5
• Average pace (3.0 mph / 4.8 km/h): MET = 3.5
• Brisk pace (3.5 mph / 5.6 km/h): MET = 4.3
• Fast pace (4.0 mph / 6.4 km/h): MET = 5.0
• Uphill walking (3.5 mph, 5–10% grade): MET = 5.3–8.0

Simplified rule of thumb: Calories ≈ 0.57 × Body Weight (lbs) × Distance (miles)

What each variable means:

• MET — Metabolic Equivalent of Task; 1 MET = the energy used at rest. Walking at MET 3.5 burns 3.5× your resting rate.
• Body Weight — heavier people burn more calories per mile (more mass to move).
• Time vs. Distance — at the same pace, both give the same result; time is useful when you’re tracking a walk; distance is useful when planning a route.

Worked examples: Person weighing 80 kg (176 lbs) walks 5 km (3.1 miles) at brisk pace (5.6 km/h) in 53.5 minutes (0.892 hours).

MET method: 4.3 × 80 × 0.892 = 307 calories Rule of thumb: 0.57 × 176 × 3.1 = 311 calories

Terrain effects: Walking uphill adds 30–60% more calorie burn per mile compared to flat terrain. A 10% grade at 3.5 mph roughly doubles calorie expenditure. Soft surfaces (sand, grass) add ~20–30% compared to pavement.

To lose 1 pound: burn approximately 3,500 extra calories. At 300 cal/5km walk, that’s roughly 12 walks per pound.
