How Many Calories Does Walking Actually Burn? October 2026

Walking burns roughly 80 to 140 calories per mile and about 200 to 400 calories per hour for an average adult, and the exact number comes down to two things: how much you weigh and how fast you move. A 150-pound adult walking at an ordinary 3 mph pace covers a mile in 20 minutes and uses about 85 calories doing it.

That is the honest answer, and it is deliberately a range. If a website or a watch tells you one exact figure, it made that number up from an average of people who do not look like you.

How Many Calories Does Walking Actually Burn?

The short version: about 100 calories per mile and 250 calories per hour for a 150-pound adult at a moderate, conversational pace.

Here is where that number comes from. Walking is measured in METs, a metabolic equivalent that scores how hard an activity is relative to sitting still. A 3 mph walk on level ground scores about 3.5 METs. Multiply your weight in kilograms by 3.5, by the MET value, by the hours, then divide by 200. That gives you the calories.

I know that sounds more like a chemistry problem than a walk. The Mayo Clinic frames the same idea in plainer terms: adding 30 minutes of brisk walking to your day can burn roughly 150 extra calories. Same arithmetic, friendlier packaging.

One more thing worth saying up front. Every figure in this article is a gross number, meaning it includes the calories you would have burned sitting at a desk during the same hour. The calories actually added to your day are lower. I break that down further below because it is the part most people get wrong.

Calories Burned by Walking Pace

Walking faster does not meaningfully change what a mile costs you, but it does change how many miles you cover in the time you have. That single mechanic explains almost every table on this topic.

Here is a 150-pound adult, level ground, at four common paces:

Pace	METs	30 minutes	45 minutes	1 hour
Slow stroll, 2 mph	2.8	about 100	about 150	about 200
Moderate, 3 mph	3.5	about 125	about 190	about 250
Brisk, 3.5 mph	4.3	about 155	about 230	about 305
Power walk, 4 mph	5.0	about 180	about 270	about 355

Why per-mile numbers barely move but per-hour numbers climb

Walk a mile slowly or quickly and it costs you roughly the same 80 to 90 calories at 150 pounds. Your body is moving its own weight over the same distance either way, so the work per mile is close to constant.

Speed only changes how quickly that work piles up. Double your pace and you finish the mile in half the time, which means twice the calories per hour even though the mile itself cost the same. The most-upvoted rule of thumb I found on r/runninglifestyle puts it more bluntly: roughly 100 calories a mile, walking or running, good enough for anyone who does not want to fuss with a calculator.

That advice carries a warning with it. Pushing to a hard power walk to chase calories raises your injury risk for a smaller return per mile than most people expect. Rocky Snyder, a CSCS trainer, frames it as the tortoise and the hare, and he is not wrong.

How Walking Calories Change With Body Weight

Body weight is the single biggest lever you control, and it is a straight one. Heavier walkers burn proportionally more on every step, at every pace.

This table covers 30 minutes of moderate walking at 3 mph, level ground:

Body weight	Per 30 minutes	Per hour	Per mile
130 pounds	about 110	about 215	about 70
150 pounds	about 125	about 250	about 85
170 pounds	about 140	about 285	about 95
190 pounds	about 160	about 315	about 105
210 pounds	about 175	about 350	about 115

The scaling rule is simple: take the 150-pound row and multiply by your weight divided by 150. At 200 pounds, a moderate mile costs about 115 calories. At 250 pounds, about 140.

The MET values behind these numbers come from the Compendium of Physical Activities, the reference table that most reputable calculators draw from. I would rather point you at a source than a black box.

How to Estimate Your Walking Calories

You do not need an app. Three approaches, easiest first.

The weight times distance shortcut

Multiply your weight in pounds by the miles you walked, then multiply by 0.55. For a 150-pound adult walking 2 miles: 150 x 2 x 0.55 = 165 calories. Close enough to the table above and it takes two seconds.

The step count method

Average stride length for an adult is about 2.5 feet, so 10,000 steps covers roughly 25,000 feet, or about 4.7 miles. Feed that distance into the formula above. At 150 pounds you get about 4.7 x 150 x 0.55 = 390 calories. At 110 pounds, closer to 285.

That is why the familiar claim that 10,000 steps always equals 500 calories only holds for a heavier adult, and why people on r/loseit argue about it constantly. One user there, a 5-foot-4 woman at 154 pounds, said she could not work out whether her daily steps were worth 200 calories or 400. The honest answer for her is about 380.

The METs method, when you want the real figure

Calories = METs x 3.5 x body weight in kg / 200 x minutes. Look up the MET value for your pace and terrain, then run it. This is the method the Compendium itself uses, and it is the only one that accounts for uphill walking properly.

Why your watch gives a different number

Watches do not measure calories. They measure steps or heart rate, then estimate energy from a formula built for the average person of your age and size. The margin of error on steady-state walking is wide enough that users routinely call the results inaccurate. On r/AppleWatch, people report watches showing fewer calories for an hour of walking than for a shorter session of something else. One Amazfit user reported over 1,000 calories from a 7-mile walk, which no plausible calculation supports.

Use your watch for step trends and treat the calorie figure as a rough companion, not a receipt.

What Changes the Calories You Burn Walking

Six factors move the number, roughly in order of how much they matter.

Body weight. Already covered, and the biggest single factor.

Pace. Raises calories per hour, not per mile, because you cover more ground in the same window.

Terrain and grade. Hills are expensive. Walking a 6 to 15 percent grade roughly doubles the cost of a flat mile: a 150-pound adult goes from about 85 calories to roughly 125 per mile. Walking downhill costs less, though it stresses the knees more, so it is not a good calorie trade.

Carried load. A weighted vest or a loaded backpack adds dead weight you must move the entire time. Ten extra pounds is close to a ten percent increase in cost at any pace.

Age and sex. These shift your basal metabolic rate, which is the floor under the walking calories. It is a modest effect at any single walk.

Walking style. Interval walking, alternating a brisk minute with an easy one, raises the average intensity over the session without the sustained strain of one hard effort.

Net calories versus gross calories

A 150-pound adult at 3 mph burns about 250 calories an hour gross. Sitting still for that hour burns about 75. The net figure, the calories actually added to your day, is closer to 175.

This is the distinction that makes a walk sound more useful than it first appears. 175 net calories is not a rounding error, it is roughly the calorie count of a small bowl of cereal, and it arrives without any change to what you eat.

Walking Calories by Distance

Distance is the most reliable way to think about it, because a mile always costs about the same. Here is a 150-pound adult at a moderate pace:

Distance	Flat ground	At a 6 to 15 percent grade	Time at 3 mph
1 mile	about 85	about 125	20 minutes
2 miles	about 170	about 250	40 minutes
3 miles	about 250	about 375	60 minutes
5 miles	about 415	about 625	1 hour 40 minutes

Scale the flat column by your weight over 150 to get your own figure. So for a 200-pound adult, 3 miles is closer to 335 calories.

If you want to know how many miles it takes to burn 1,000 calories, the answer for a 150-pound adult is around 12 miles on the flat. That is a long morning, which is why nobody recommends it as a daily habit.

How to Use Walking for Weight Loss

One kilogram of body fat holds roughly 7,700 calories. That single conversion explains why walking feels slow: an hour of moderate walking nets you about 175 calories, so a daily hour works out to roughly 16 pounds over a year. Add that to a diet and the arithmetic stops looking hopeless.

This breakdown of calories burned walking puts the same per-session numbers in a different format. Weekly activity guidance treats walking as a way to hit a target rather than a calorie-burning contest. Consistency beats intensity here, because a walk you take most days for a year will beat a heroic walk you take twice.

Three habits make it work better:

• Build up gradually. Start at the pace you can hold without puffing and add five minutes a week.
• Lengthen before you harden. More time at an easy pace is easier on joints than a shorter, faster effort.
• Leave room for nutrition. Walking creates a modest deficit. It works best alongside eating habits that do not undo it.

How to walk to burn more calories

Pick hills instead of speed when a route allows it. A steady climb at a comfortable pace often beats a flat sprint on the same clock. Add intervals: one minute at 3.5 to 4 mph, then two minutes back at 2 mph, repeated for a half hour. Set the treadmill incline to 1 or 2 percent if you walk indoors, since a flat belt underestimates outdoor effort.

For a serious bump, a weighted vest or backpack works, but go light. Ten pounds is plenty, and anything heavier on a long walk is a joint problem waiting to happen.

Walk more often rather than harder. Three 20-minute walks produce nearly the same burn as one 60-minute walk, and they are far easier to keep doing.

Frequently Asked Questions

Start with the simple version of how many calories does walking actually burn: about 100 calories a mile, more if you weigh more and more again if the ground tilts up. Find your own number in the weight table, pick a route you would actually walk again tomorrow, and let consistency do the compounding.
