Calories Burned Walking Calculator

Estimate calories burned walking or hiking from duration, pace, incline, and body weight — including net versus gross burn.

Short answer

Calories Burned Walking Calculator

216Calories burned (gross)

Net burn is the honest number for weight management — you would have burned 63 kcal resting anyway. Incline is the biggest free multiplier: raising the grade to 5% at the same pace would push you to 354 kcal.

How it's calculated: 216 kcal in 45 min · 153 kcal net of what you'd burn sitting. Adjust the inputs below to recalculate for your own numbers.

Formula used

ACSM walking metabolic equation

The ACSM equation is the standard used in exercise physiology labs. It converts speed and grade directly into oxygen consumption, which converts to calories at roughly 5 kcal per liter of O₂.

VO₂ = 0.1×speed + 1.8×speed×grade + 3.5 (ml/kg/min) · kcal = VO₂ × kg ÷ 1000 × 5

Incline beats speed for calorie burn

Walking faster gets uncomfortable quickly, but adding grade raises energy cost sharply while staying joint-friendly. A 10% incline at 3 mph roughly doubles flat-ground burn, which is why weighted incline walking has become the default low-impact conditioning tool.

  • Do not hold the treadmill handrails — it cuts the real cost by 20–25%.
  • A weighted pack adds burn in direct proportion to total mass carried.
  • Downhill walking burns less but loads the knees eccentrically.

FAQ

How many calories does a 30-minute walk burn?

For a 175 lb person at 3.2 mph on flat ground, roughly 150–180 calories gross and about 120–140 net.

Does walking uphill burn more calories?

Substantially. Each 1% of grade adds roughly 8–12% to energy cost at typical walking speeds.

Is walking or running better for weight loss?

Running burns more per minute, walking is easier to sustain daily and provokes less compensatory eating. The best option is the one you will keep doing.
