How Many Calories Per Mile Walking by Body Weight?
Walking calorie burn per mile scales linearly with body weight in the MET formula. Every additional 10 lb of body weight adds approximately 5 to 8 more calories per mile at any given pace. The table below uses MET 4.3 (brisk walk, 3.5 mph) as the baseline.
Body Weight | Cal/Mile (Brisk 3.5 mph) | Cal/Mile (Moderate 3.0 mph) | Cal/km |
|---|---|---|---|
120 lb (54 kg) | 70 kcal | 63 kcal | 44 kcal |
130 lb (59 kg) | 76 kcal | 69 kcal | 47 kcal |
140 lb (64 kg) | 82 kcal | 75 kcal | 51 kcal |
150 lb (68 kg) | 88 kcal | 79 kcal | 55 kcal |
154 lb (70 kg) | 88 kcal | 81 kcal | 55 kcal |
170 lb (77 kg) | 99 kcal | 90 kcal | 62 kcal |
185 lb (84 kg) | 106 kcal | 98 kcal | 66 kcal |
200 lb (91 kg) | 115 kcal | 105 kcal | 72 kcal |
220 lb (100 kg) | 126 kcal | 115 kcal | 78 kcal |

Walking calories per mile at 150 pounds comes to approximately 88 kcal at brisk pace. The fast formula for any weight: body weight in lbs × 0.53 = approximate gross calories per mile at brisk pace, per research cited at macronutrients.com.
Is the "100 Calories Per Mile Walking" Rule Accurate?
The 100-calorie-per-mile rule is a rough average. It applies reasonably well for adults weighing approximately 175 to 190 lb walking at moderate to brisk pace on flat terrain. For anyone outside that range, the rule either significantly overstates or understates actual output.
When the 100-Calorie Rule Overstates Burn
Body weight below 150 lb: a 130 lb walker burns only 76 kcal per mile at brisk pace
Slow pace below 2.5 mph: lower MET reduces per-mile output by 15 to 20%
Flat treadmill at 0% incline: slightly lower than outdoor equivalent
When the 100-Calorie Rule Understates Burn
Body weight above 200 lb: a 220 lb walker burns 126 kcal per mile, 26% above the rule
Uphill grade above 5%: incline raises per-mile burn by 30 to 60%
Power walking above 4.5 mph: MET rises to 6.3, pushing per-mile output well above 100 kcal
The formula body weight (lbs) × 0.53 gives a more accurate flat-ground brisk-pace estimate. For a 200 lb walker: 200 × 0.53 = 106 kcal per mile, matching the MET table closely.
Does Walking Pace Change Calories Burned Per Mile?
Walking pace changes calories per minute significantly but calories per mile only modestly. Faster paces carry higher MET values but cover the mile in less time. These two effects largely cancel, keeping per-mile output within a relatively narrow band across all walking speeds.
Calories Per Mile by Pace (154 lb / 70 kg, Flat Terrain)
Pace | Speed | MET | Min Per Mile | Cal Per Mile |
|---|---|---|---|---|
Very slow stroll | 2.0 mph | 2.5 | 30 min | 58 kcal |
Slow walk | 2.5 mph | 3.0 | 24 min | 63 kcal |
Moderate walk | 3.0 mph | 3.5 | 20 min | 73 kcal |
Brisk walk | 3.5 mph | 4.3 | 17 min | 88 kcal |
Fast walk | 4.0 mph | 5.0 | 15 min | 88 kcal |
Power walk | 4.5 mph | 6.3 | 13.3 min | 98 kcal |
Race walk | 5.0 mph | 8.0 | 12 min | 112 kcal |
Gross calories at 70 kg on flat terrain.
The difference between a slow 2.5 mph walk and a brisk 3.5 mph walk per mile is only 25 kcal for a 154 lb person. Pace matters far more for how quickly you accumulate miles than for how many calories each mile produces.
Slow Walk Calories Per Mile vs Brisk Walk
Slow walk calories per mile at 2.5 mph: approximately 63 kcal for a 154 lb person. Brisk walking calories per mile at 3.5 mph: approximately 88 kcal. The 40% difference between those paces is the widest realistic gap for most adults. Beyond 4.0 mph, per-mile output plateaus because the time reduction nearly offsets the MET increase.
MET Walking Calories Per Mile: How the Formula Works
MET (Metabolic Equivalent of Task) is the scientific unit behind all walking calorie estimates. The formula is:
Calories per mile = MET × weight (kg) × (minutes per mile ÷ 60)
For a 154 lb (70 kg) walker at 3.5 mph (MET 4.3, 17 min per mile): Calories = 4.3 × 70 × (17 ÷ 60) = 85 kcal (approximately 88 kcal with rounding from the full compendium value).
MET values for all walking speeds come from the 2024 Adult Compendium of Physical Activities (Ainsworth et al.), the primary reference used by the American College of Sports Medicine. This is the same dataset used by the main calories burned calculator.
Calories Per Mile Walking Uphill: How Incline Changes Output
Walking uphill burns substantially more calories per mile than flat walking. At 3.5 mph, going from 0% to 5% grade raises the MET value from about 3.6 to 5.1. At 10% it is roughly 6.6 METs. That translates to large per-mile calorie increases without any change in distance.
Calories Per Mile Walking at Grade (154 lb / 70 kg, 3.5 mph)
Incline Grade | MET | Cal Per Mile | Increase vs Flat |
|---|---|---|---|
0% flat | 4.3 | 88 kcal | baseline |
3% | 5.1 | 104 kcal | +18% |
5% | 6.0 | 122 kcal | +39% |
8% | 7.2 | 147 kcal | +67% |
10% | 8.0 | 163 kcal | +85% |
15% | 9.5 | 194 kcal | +120% |
Based on ACSM walking metabolic equation: VO2 = 0.1 × speed + 1.8 × speed × grade + 3.5.
A 5% grade increases calorie expenditure by roughly 30 to 40% compared to flat terrain. A steep 10% grade can increase burn by 50 to 60%. Adding incline is the most time-efficient lever for raising per-mile walking calorie output without increasing pace or distance.
Net Calories Walking Per Mile vs Gross Calories
Gross calories per mile includes resting metabolic rate (RMR) during the walk time. Net calories subtracts RMR, showing only the additional energy created by walking.
For a 154 lb (70 kg) person walking 1 mile at 3.5 mph (17 minutes):
Metric | Value |
|---|---|
Gross calories per mile | 88 kcal |
RMR during 17 minutes (~0.7 kcal/min) | ~12 kcal |
Net calories per mile | ~76 kcal |
Net calories walking per mile are approximately 12 to 15% below gross calories. Most apps, trackers, and calculators report gross calories. Net calories matter more for weight management tracking because you would have burned RMR calories at rest regardless.
Calories Per Mile Walking vs Running: Full Comparison
Running burns more calories per mile than walking, but the per-mile gap is smaller than most people expect. For a 150 lb person, running at 6 mph burns about 100 to 110 calories per mile, compared to 75 for walking at 3 mph. The flight phase of running, where both feet briefly leave the ground, accounts for the additional per-mile cost.
Activity | Speed | Cal Per Mile (154 lb) | Time Per Mile |
|---|---|---|---|
Slow walk | 2.5 mph | 63 kcal | 24 min |
Brisk walk | 3.5 mph | 88 kcal | 17 min |
Power walk | 4.5 mph | 98 kcal | 13.3 min |
Jogging | 5.0 mph | 99 kcal | 12 min |
Running | 6.0 mph | 112 kcal | 10 min |
Running 6 mph burns 27% more per mile than brisk walking 3.5 mph. Per minute of exercise, the gap is far larger. Running covers that mile in 10 minutes versus 17 minutes for brisk walking, burning 80% more calories per minute of effort.
How Many Miles to Walk to Burn 300 Calories?

Frequently Asked Questions About Calories Burned Walking Per Mile
How Many Calories Per Mile Does Walking Burn?
Walking burns between 65 and 130 calories per mile depending on body weight and pace. A 130 lb person burns approximately 76 kcal per mile at brisk pace. A 185 lb person burns approximately 106 kcal. A 220 lb person burns approximately 126 kcal. All values use MET 4.3 at 3.5 mph on flat terrain.
How Many Calories Does Walking 1 Mile Burn at 150 Pounds?
A 150 lb (68 kg) person burns approximately 88 gross calories per mile at brisk 3.5 mph. At slow 2.5 mph, the same person burns approximately 63 kcal per mile. At power-walking 4.5 mph, the output rises to approximately 97 kcal per mile. The range across all walking speeds is only 34 kcal, confirming body weight dominates over pace. For the full 1-mile breakdown, the calories burned walking 1 mile page covers weight and pace tables in detail.
Does Brisk Walking Burn More Calories Per Mile Than Slow Walking?
Brisk walking burns approximately 40% more calories per mile than a slow 2.5 mph walk for the same body weight. A 154 lb person burns 88 kcal per brisk mile versus 63 kcal per slow mile. The increase comes from the higher MET value at brisk pace, which more than compensates for the shorter time spent on the mile.
How Accurate Are Walking Calorie Estimates Per Mile?
MET-based per-mile estimates are accurate within 10 to 15% of laboratory-measured values for most adults on flat terrain at moderate pace. Individual variation in walking economy, body composition, and biomechanics accounts for most of the uncertainty. Sports watches and fitness trackers typically achieve 7 to 10% accuracy per session, per Garmin's published data.
