Walking Calorie Calculator: Calories Burned Walking

Walking Calorie Calculator: How Many Calories Does Walking Burn?

Walking is the most underrated exercise there is. It needs no equipment, almost anyone can do it every day, and it adds up. But the calorie numbers people quote for it vary wildly, from fitness trackers that flatter you to rules of thumb with no source. The calculator above uses the measured energy costs researchers rely on, from the 2024 Compendium of Physical Activities, and shows you both the total burn and the part that actually counts toward a calorie deficit.

Key takeaways

1. A 70 kg adult walking at a moderate 5 km/h burns about 270 kcal an hour in total. The 2024 Compendium of Physical Activities rates that pace at 3.8 METs, and a brisk 6 km/h at 4.8

2. About a quarter of that total is energy you would burn anyway at rest. The net figure is the one that matters for weight loss, and the standard formula may overestimate resting burn by about 20%

3. The bigger payoff of walking is longevity. In 15 cohorts with 47,471 adults, more daily steps meant a progressively lower risk of death, levelling off at 6,000 to 8,000 steps a day from 60 and 8,000 to 10,000 below 60

Below you will find how the calculation works, the calories burned at each walking speed, what hills add, how much 10,000 steps burn, why the net number is smaller than the headline, and what walking does for weight, blood sugar and lifespan.

How the Calculation Works: METs Explained

Exercise scientists describe the energy cost of an activity in METs, short for metabolic equivalents. One MET is the energy you use sitting quietly, set by convention at 1 kcal per kilogram of body weight per hour. An activity rated at 4 METs costs four times that.

The values come from the Compendium of Physical Activities, a reference list first published in 1993 and updated in 2024. The 2024 Adult Compendium screened over 32,000 studies and now lists 1,114 activities, most of them measured with indirect calorimetry rather than estimated. It is tailored to adults aged 19 to 59.

From there the arithmetic is simple: calories burned = METs x body weight in kg x hours. A 70 kg person walking for one hour at 3.8 METs burns 3.8 x 70 x 1 = 266 kcal. Because weight is part of the formula, a heavier person burns more on the same walk.

Calories Burned Walking by Speed

Speed matters more than most people expect, because the energy cost of walking does not rise in a straight line. Here is one hour on level ground for a 70 kg adult, using the 2024 Compendium values:

3 km/h, strolling: 2.3 METs, about 160 kcal.
4 km/h, slow: 2.8 METs, about 195 kcal.
5 km/h, moderate: 3.8 METs, about 265 kcal.
6 km/h, brisk: 4.8 METs, about 335 kcal.
7 km/h, very brisk: 5.5 METs, about 385 kcal.
7.5 km/h: 7.0 METs, about 490 kcal.
8.5 km/h: 8.5 METs, about 595 kcal.

Two patterns stand out. Between about 4 and 7 km/h, the cost per kilometre changes little, from about 50 to 56 kcal for a 70 kg person: walking briskly mostly means you finish sooner. Above about 7 km/h the cost per kilometre climbs to 65 kcal and more. Above 8.9 km/h the Compendium has no walking values at all, because at that speed most people run.

Walking Uphill: What Incline Adds

Hills are the easiest way to make a walk harder without walking faster. The 2024 Compendium lists hill walking without a load at 5.3 METs for a 1 to 5% grade at a moderate to brisk pace, 7.0 METs for 6 to 10%, and 8.8 METs for 11 to 20% at a slow to moderate pace.

For a 70 kg person, an hour on a moderate incline of 6 to 10% burns about 490 kcal, nearly twice the 266 kcal of the same time at 5 km/h on the flat. A steep 11 to 20% climb reaches about 615 kcal. That is why a treadmill incline or a hilly route is a practical way to raise intensity for people who do not want to run.

How Many Calories Do 10,000 Steps Burn?

Steps are the way most people track walking, so it helps to connect the two. In a lab study of adults aged 21 to 40, a cadence of 100 steps per minute marked moderate intensity, about 3 METs, and 130 steps per minute marked vigorous intensity, about 6 METs.

At 100 steps per minute, 10,000 steps take 100 minutes. For a 70 kg person at 3 METs that is about 350 kcal in total, or about 235 kcal net. Walk faster and the same steps cost more: at 130 steps per minute, the vigorous threshold, 10,000 steps take about 77 minutes at 6 METs, roughly 540 kcal in total. Most people's daily steps are spread out and slower than 100 a minute, so for a normal day the lower figure is the more realistic one.

Gross vs Net Calories: Why the Number Is Smaller Than It Looks

The headline figure in the calculator is your gross burn: everything your body used during the walk, including the energy it would have used anyway. If you had spent the same hour on the sofa, you would still have burned about 1 MET's worth. The net figure subtracts that, and it is the number to use when you plan a calorie deficit. At 3.8 METs, the net share is 2.8 METs, about three quarters of the total.

There is a second reason to read the result conservatively. The 1 kcal per kg per hour convention was derived from a single 70 kg, 40-year-old man. When researchers measured resting energy use in 769 adults, it averaged 0.84 kcal per kg per hour, meaning the standard value overestimates resting burn by about 20%. Body composition explained most of the difference. For adults over 60, a separate Older Adult Compendium uses a lower resting value for the same reason.

Walking for Weight Loss

Walking does help with weight, but the effect is steady rather than dramatic. A meta-analysis of 24 randomised controlled trials found that walking programmes reduced body weight, BMI and body fat in previously sedentary adults, while also raising aerobic fitness and lowering resting diastolic blood pressure.

The maths explains why the effect is modest. An hour of walking at 5 to 6 km/h adds roughly 200 to 270 net kcal for a 70 kg person, which a single snack can cancel. The advantage is that you can do it every day without needing recovery, and the calories add up over weeks. Pair it with the calorie deficit calculator to see what a daily walk is worth in your plan, and with strength training to protect muscle while you lose fat.

Walking After Meals

When you walk can matter too, not only how far. A meta-analysis of randomised crossover trials compared long, uninterrupted sitting with frequent short breaks of standing or light walking. Light walking breaks lowered blood sugar and insulin after meals compared with continued sitting, and did so more effectively than standing breaks.

These were short, single-day lab studies, so they show an acute effect rather than a long-term outcome. Still, a few minutes of easy walking after eating costs almost nothing and helps your body deal with the meal. It is one of the simplest habits for metabolic health, and it adds steps to your day.

Steps and Longevity: How Much Walking Is Enough?

The strongest argument for walking is not calories. In a meta-analysis of 15 cohorts with 47,471 adults, people in the highest quartile of daily steps (a median of about 10,900) had a 53% lower risk of dying during follow-up than those in the lowest quartile (about 3,550 steps). The benefit levelled off at 6,000 to 8,000 steps a day for adults aged 60 and older and at 8,000 to 10,000 steps for younger adults.

A US study of 4,840 adults aged 40 and older found a similar pattern: compared with 4,000 steps a day, 8,000 steps were linked to about half the risk of death, and 12,000 steps to an even lower risk. Once total steps were accounted for, walking faster did not add a significant extra benefit. Both studies are observational, so they show a strong link rather than proof of cause, but the message is consistent: the total number of steps you take each day counts most.

Frequently Asked Questions

How many calories does walking burn per hour?

It depends mostly on your weight and speed. A 70 kg adult burns about 195 kcal an hour at a slow 4 km/h, about 265 kcal at a moderate 5 km/h and about 335 kcal at a brisk 6 km/h, based on the 2024 Compendium of Physical Activities. A heavier person burns proportionally more.

How many calories do 10,000 steps burn?

For a 70 kg adult walking at a moderate 100 steps per minute, 10,000 steps take about 100 minutes and burn roughly 350 kcal in total, or about 235 kcal above resting. Slower, spread-out daily steps burn somewhat less.

Does walking uphill burn more calories?

Yes, a lot more. The 2024 Compendium rates walking up a 6 to 10% grade at 7.0 METs, compared with 3.8 METs for a moderate pace on the flat. For a 70 kg person that is about 490 kcal an hour instead of 265.

Is walking enough to lose weight?

It helps. Trials show regular walking reduces body weight and body fat in previously inactive adults, but the effect is gradual. Combine a daily walk with a moderate calorie deficit and strength training for the best results, and count the net calories rather than the gross figure.

How many steps a day should I walk?

In a large meta-analysis, the risk of death kept falling with more steps up to about 6,000 to 8,000 a day for adults over 60 and 8,000 to 10,000 a day for younger adults. Any increase from a low baseline is worth it.
