About Us

Welcome to WalkingCalorieCalculator.cyou — a free online tool that answers one simple question: how many calories did that walk burn?

Our Mission

Walking is the world's most popular exercise — free, gentle on the joints, and something almost everyone can do. But when it comes to tracking calories, most fitness apps are overloaded with features, accounts, subscriptions, and ads. We wanted the opposite: a calculator that opens instantly, works on any device, and gives you a trustworthy number in seconds.

The Science Behind Our Calculator

Our calculator uses the ACSM walking equation to estimate oxygen use from walking speed and a steady incline. Oxygen use is converted to calories at approximately 5 kcal per liter. The same equation powers our calculator, examples and charts.

Total kcal = VO₂ × weight (kg) × minutes ÷ 200

We show total energy and active energy above an estimated resting baseline. The model does not measure individual metabolism and we do not claim a fixed accuracy percentage. Steps mode estimates step length from height, so measured distance is preferable when available.

See our formula, assumptions and source reference, including Texas ACSM research abstracts documenting the equation and calorie conversion.

What Makes Us Different
