Calories Burned Running Calculator
Running burns more per minute than almost anything else you can do without equipment — but how much more depends on three things: your weight, your pace, your minutes. This calculator uses MET values (metabolic equivalents) from the Compendium of Physical Activities: one MET is your resting burn, and running multiplies it. At the defaults — 170 lb, 6 mph, 30 minutes — that is 397 calories (132 per mile, about 20% of a 2,000-calorie day). Enter your numbers, and read the pace table to see what speed is really worth.
How the MET math works
One MET = the energy you burn sitting still (about 1 kcal per kilogram of body weight per hour). Every activity is a multiple of that. Running 6 mph is rated 9.8 METs — roughly ten times resting. The formula:
Calories = METs × 3.5 × weight(kg) ÷ 200 × minutes.
At the defaults: 9.8 × 3.5 × 77.1 kg ÷ 200 × 30 = 396.74 calories. Six miles per hour for 30 minutes covers 3.0 miles, so that is 132.2 calories per mile — the number runners actually compare.
The pace table: what speed is worth
MET values from the Compendium of Physical Activities. The “per hour” column is for a 170 lb runner — your weight scales it. Note the pattern: doubling the speed more than doubles the burn, because air resistance and stride cost climb faster than pace.
| Pace | METs | Cal/hr (170 lb) |
|---|---|---|
| 5 mph (12:00/mi) | 8.3 | 672 |
| 6 mph (10:00/mi) | 9.8 | 793 |
| 7 mph (8:34/mi) | 11.0 | 891 |
| 7.5 mph (8:00/mi) | 11.5 | 931 |
| 8 mph (7:30/mi) | 11.8 | 955 |
| 9 mph (6:40/mi) | 12.8 | 1036 |
| 10 mph (6:00/mi) | 14.5 | 1174 |
| 12 mph (5:00/mi) | 19.0 | 1538 |
The worked example, three ways
Defaults: 170 lb × 6 mph × 30 min = 396.74 cal (132.2/mi). Lighter runner: 150 lb at the same pace and time = 350.06 cal — about 12% less, because there is less body to move. Faster runner: 170 lb at 10 mph (14.5 METs) × 30 min = 587.01 cal — 48% more than the 6-mph run, for the same half hour. The cheapest way to burn more is pace; the second cheapest is minutes.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Calories burned | METs × 3.5 × kg ÷ 200 × min | 396.74 at the defaults — the session total. |
| Per mile | calories ÷ miles | 132.2 at the defaults — the runner’s benchmark number. |
| Share of the day | calories ÷ 2,000 | 19.8% of a 2,000-calorie day at the defaults. |
Who uses this
- New runners: translating “I ran 20 minutes” into a number they can log against their food.
- Weight-loss planners: a 500-calorie daily deficit is the classic target — this shows how many minutes that actually costs.
- Race trainers: per-mile burn matters more than session totals when fueling long runs.
- Curious walkers: run the same weight through our walking calculator and see exactly what the speed premium buys you.
Accuracy & limitations
MET values are population averages from the Compendium of Physical Activities — your engine differs by fitness, efficiency, age, terrain, wind, and temperature. Treadmills read slightly lower than roads (no air resistance, no hills); trails read higher. The formula gives gross burn, including what you would have burned sitting still; the exercise-only (“net”) number is roughly 10–15% lower. Watches estimate from heart rate and often disagree — treat all of these as planning numbers, not lab measurements. Not medical advice.

How many calories does running burn per mile?
Roughly 100–160 calories per mile for most adults, scaling with weight: about 132 per mile for a 170 lb runner at 6 mph. Per-mile burn rises slowly with pace — most of the extra burn at speed comes from covering more miles, not from a much higher per-mile rate.
What is a MET in running?
A metabolic equivalent of task: 1 MET is your resting energy burn. Running is rated 8–19 METs depending on speed (Compendium of Physical Activities) — 6 mph is 9.8 METs, 10 mph is 14.5. Calories = METs × 3.5 × your weight in kg ÷ 200 × minutes.
Does running burn more calories than walking?
Yes, roughly double per minute at typical paces: walking 3 mph is ~3.3 METs against running 6 mph at 9.8. Per mile the gap is smaller — walking a mile still moves the same body the same distance — which is why slow jogging a long way beats fast walking a short way for total burn.
How long do I need to run to burn 500 calories?
At the defaults (170 lb, 6 mph), about 38 minutes (397 cal per 30 min → 500 ÷ 13.2/min). A 150 lb runner needs ~43 minutes; at 8 mph a 170 lb runner needs ~28. Enter your weight and pace above for your exact number.
Why does my watch say something different?
Watches estimate from heart rate, which is affected by caffeine, heat, stress, and cardiac drift — they commonly read 10–30% high or low against lab measurement. The MET formula uses pace and weight only, so it disagrees with watches on hilly or hot days. Use one method consistently for trends.
Does running on a treadmill burn fewer calories?
Slightly. No air resistance and no terrain variation shave roughly 5% off the outdoor number at the same pace — treadmill runners often set a 1% incline to close the gap. The calculator’s numbers assume level outdoor running.
