Calories by time, not by count

Walking calorie calculator

Estimate the calories you burn walking for 15, 30 or 60 minutes from your body weight and walking intensity, with total and active energy shown separately.

30 minutes at 3.8 MET for 70 kg. Gross includes resting energy; active excludes it. An estimate, not a measurement.

Energy estimates vary with pace, terrain and individual physiology.

Gross kcal = MET × 3.5 × weight in kg × minutes ÷ 200; active kcal uses MET − 1

How many calories do you burn walking for 30 minutes?

It depends mostly on your body weight and how briskly you walk. For a 70 kg walker at a moderate pace (3.8 MET, roughly 2.8–3.4 mph on level ground), 30 minutes comes to about 140 kcal in total, of which around 103 kcal is above what you would have used at rest. At 90 kg the same walk is about 180 kcal in total; at a brisk 4.8 MET the 70 kg figure rises to about 176 kcal.

The calculator above uses the standard MET equation from the Compendium of Physical Activities: kilocalories per minute equal MET × 3.5 × body mass in kilograms ÷ 200. Multiply by minutes for the total. The “active” figure subtracts one MET so that resting energy is not counted as exercise.

When to use time instead of steps

The steps-to-calories tool starts from a step count and turns it into minutes with a cadence. This walking calculator skips that step: if you know you walked for 45 minutes, enter 45 minutes. It suits treadmill sessions, timed lunchtime walks and anything your watch records as a duration rather than a count. (If you searched for a “calories burnt walking calculator” with British spelling, this is the same tool.)

For a distance you know rather than a time, the calories-per-mile calculator takes miles and a pace directly. Calories burned walking 6.5 miles, for example, come to about 586 kcal in total for a 70 kg walker at 3.1 mph.

What the estimate leaves out

MET values describe categories of activity, not your individual metabolism. Hills, carried loads, soft ground, wind and your fitness all change the real energy cost, and the Compendium values are drawn from adults aged 19–59. Treat the result as a scenario estimate with visible assumptions, and compare like with like: a total figure from one tool against a total figure from another.

Calories burned walking by weight and time

The calculator above takes one weight and one intensity. The table sets four common body weights against four walking times at a moderate 3.8 MET, so you can see how the two inputs pull against each other: a shorter walk at a heavier body weight can match a longer walk at a lighter one.

Figures are total (gross) kilocalories, which include the energy you would have spent at rest over the same minutes. Subtract roughly one MET worth if you want the active-only number; the calculator shows both.

A few useful answers

Walking calories: questions, answered.

How many calories do you burn walking for 15 minutes?

About 70 kcal in total for a 70 kg walker at a moderate 3.8 MET, or roughly 51 kcal above resting. Half the 30-minute figure, because the model is linear in time.

Does walking faster burn more calories per minute?

Yes. The Compendium assigns 2.8 MET to slow walking and 5.5 MET to very brisk walking, so a very brisk minute costs almost twice as much energy as a slow one at the same body weight.

Is this the same as the steps-to-calories calculator?

It uses the same MET equation and the same intensity presets. The only difference is the input: minutes here, steps and cadence there. Both pages give the same answer for the same walking time.

How long do you need to walk to burn 400 calories?

About 86 minutes for a 70 kg walker at a moderate 3.8 MET, counting total energy. At a brisk 4.8 MET it is about 68 minutes. Heavier walkers get there sooner, lighter walkers later.

How many calories does walking for 2 hours burn?

About 559 kcal in total for a 70 kg walker at a moderate 3.8 MET, or about 412 kcal above resting. Four hours at the same pace is double: about 1,117 kcal.
