A 155-pound (70 kg) person burns roughly 130 calories walking for 30 minutes at a steady 3 mph pace. Drop to a casual 2 mph stroll and it is closer to 100; pick it up to a brisk 4 mph and you are nearer 185. Your own number depends mostly on two things: how much you weigh and how fast you walk.
That is the short answer. The longer answer is more useful, because walking is one of the most accessible ways to move more, and knowing roughly what it burns helps you fit it into a weight-loss plan without overestimating it. This guide gives you a calories-burned table by body weight and pace, shows the simple formula behind it so you can estimate your own, and is honest about what walking can and cannot do.
The short answer, and what drives the number
Two people can walk the same 30 minutes and burn very different amounts. The two biggest levers are:
- Your body weight. Moving a heavier body costs more energy, so a 200-pound person burns more on the same walk than a 130-pound person. This is usually the single largest factor.
- Your pace and effort. A brisk walk demands more energy per minute than an easy stroll, and walking uphill demands more still.
Other things matter a little (terrain, fitness, how efficiently you move, whether you carry a load), but weight and pace do most of the work. That is why every honest answer to “how many calories does walking burn” comes as a range, not a single figure.
Calories burned walking, by weight and pace
The table below estimates calories burned for 30 and 60 minutes of walking at four common paces, for four body weights. The numbers come from the MET-based formula explained in the next section, using walking intensity values from the 2011 Compendium of Physical Activities (Ainsworth et al., 2011).
| Pace | 125 lb | 155 lb | 185 lb | 220 lb |
|---|---|---|---|---|
| Casual stroll, ~2 mph (30 min) | 85 | 105 | 125 | 145 |
| Casual stroll, ~2 mph (60 min) | 165 | 205 | 245 | 295 |
| Steady, ~3 mph (30 min) | 105 | 130 | 155 | 185 |
| Steady, ~3 mph (60 min) | 210 | 260 | 310 | 365 |
| Brisk, ~4 mph (30 min) | 150 | 185 | 220 | 260 |
| Brisk, ~4 mph (60 min) | 300 | 370 | 440 | 525 |
| Uphill / 6 to 10% grade (30 min) | 210 | 260 | 310 | 365 |
| Uphill / 6 to 10% grade (60 min) | 415 | 515 | 615 | 735 |
Values are rounded estimates. Read across to find your weight, and down to find your pace. Notice two patterns: within any row, a heavier person burns more, and within any column, a faster or steeper walk burns more. A brisk walk burns roughly twice what a casual stroll does for the same person and time, and an uphill walk more still.
These figures line up with other reputable sources. Harvard Health, for example, publishes a widely cited table for three body weights: it lists a 155-pound person burning about 133 calories walking 3.5 mph for 30 minutes and about 175 calories at 4 mph (Harvard Health). The small differences between any two tables are exactly the point: these are estimates, and they vary by method.
The formula: how to estimate your own burn
You do not have to trust a table blindly. The standard way to estimate calories burned in any activity uses METs, or metabolic equivalents. One MET is roughly the energy your body uses at rest. An activity rated at 4 METs burns about four times the energy of sitting still. The 2011 Compendium of Physical Activities, the reference researchers use, assigns a MET value to hundreds of activities, including many flavors of walking (Ainsworth et al., 2011).
The widely used formula is:
Calories per minute = MET x 3.5 x body weight in kg / 200
To use it, you need three things: the MET value for your pace (below), your weight in kilograms (pounds divided by 2.2), and how many minutes you walked. Multiply calories per minute by your minutes to get the total.
Here are the walking MET values from the Compendium, which set the paces in the table above (Ainsworth et al., 2011):
| Walking pace | MET value |
|---|---|
| Slow, 2.0 to 2.4 mph, level | 2.8 |
| For pleasure / moderate, around 3 mph | 3.5 |
| Brisk for exercise, 3.5 to 3.9 mph | 4.8 |
| Very brisk, 4.0 to 4.4 mph | 5.5 |
| Uphill, 6 to 10% grade | 7.0 |
A worked example makes it concrete. Say you weigh 155 pounds (about 70 kg) and walk for 30 minutes at a steady 3 mph (3.5 METs):
- Calories per minute = 3.5 x 3.5 x 70 / 200 = about 4.3
- Total = 4.3 x 30 minutes = about 130 calories
Swap in a brisk 4 mph (using 5.0 METs as a round figure) and the same person burns about 6.2 calories per minute, or roughly 185 in 30 minutes. Swap in your own weight and pace and you have a personal estimate. If you would rather skip the arithmetic, our calories-burned calculator does it for you for walking and dozens of other activities.
What about calories per mile?
A lot of people prefer to think in distance rather than time. A handy rule of thumb is that walking one mile burns very roughly 80 to 100 calories for an average adult, and like everything else it scales with body weight: a lighter person lands below that range and a heavier person above it.
Here is the part that surprises people: your pace does not change the per-mile burn nearly as much as you would think. Walking a mile covers the same distance whether you stroll or stride, so the total work is similar. A faster pace mainly means you finish the mile sooner and burn those calories in less time, which is great for fitting more movement into a busy day, but it does not multiply the per-mile total. Pace matters most when you compare burn per minute, which is what the table above shows.
This is also why step counts are a reasonable proxy for walking calories. If you are working from a daily step goal, our companion guide on how many steps a day to lose weight translates steps into calories and deficits, and explains where the famous “10,000 steps” figure actually came from.
Honest framing: modest per session, but it adds up
It is worth being straight about the size of these numbers. A single 30-minute walk burns somewhere around 100 to 200 calories for most people. That is real, but it is also roughly one cookie, half a muffin, or a sugary coffee drink. This is the heart of the saying you cannot outrun a bad diet: it is far easier to eat 300 calories than to walk them off, so walking rarely undoes an indulgent meal on its own.
That is not a reason to skip the walk. It is a reason to see walking for what it is, a steady contributor rather than a magic eraser. And over time it genuinely adds up:
- Across a week, it compounds. A brisk 30-minute walk five days a week is on the order of 1,000 extra calories burned, which meaningfully widens your weekly calorie deficit.
- It is sustainable. Walking is low-impact, free, and easy to keep doing, and the best exercise is the one you actually stick with. Consistency beats intensity you abandon.
- It supports keeping weight off. Regular activity is one of the strongest predictors of maintaining weight loss, not just reaching it.
The most reliable approach is to use walking to support a modest calorie deficit rather than to create the whole deficit by itself. We compare the two levers in detail in exercise versus diet for weight loss, and the short version is that the two work best together.
There is a health case for walking that has nothing to do with the scale, too. The CDC recommends adults get at least 150 minutes a week of moderate-intensity activity, and it specifically names brisk walking as a prime example, the kind of effort where you can talk but not sing (CDC). Hitting that target supports your heart, mood, and metabolic health regardless of weight loss.
Why your real number will vary
Even a careful estimate is still an estimate. The MET formula is built on averages measured across groups of people, then scaled by body weight, so it cannot capture everything that makes your walk yours:
- Fitness and efficiency. A trained walker often moves more efficiently and may burn slightly less for the same pace, while someone less conditioned may burn a bit more.
- Terrain and surface. Sand, snow, grass, and trails cost more than a flat sidewalk; the Compendium values assume a firm, level surface unless noted.
- Carrying a load. A heavy backpack, stroller, or groceries raises the effort and the burn.
- Tracker error. Fitness watches and phone apps make their own assumptions and can be off in either direction, sometimes by 20 percent or more for a given activity.
The practical takeaway: use these numbers to plan, not to balance a precise daily ledger. If you walk regularly and your weight is trending the way you want over a few weeks, your real-world burn is working out fine, whatever the watch says.

The bottom line
Walking burns roughly 100 to 250 calories per half hour for most people, set mostly by your body weight and your pace. You can estimate your own number with the MET formula (calories per minute = MET x 3.5 x your weight in kg / 200), or read it straight off the table above. Either way, treat it as a solid ballpark, not a precise count.
The honest framing matters most: one walk is modest, and you cannot outrun a bad diet, but a regular walking habit adds up over a week, widens your calorie deficit, and is one of the easiest healthy habits to keep for life.
