Cycling is one of the most joint-friendly ways to burn calories, build endurance, and get around town, but the energy cost of a ride is not as simple as glancing at your speedometer. Your calorie burn depends on your body weight, how hard you pedal, and how long you stay in the saddle. This Cycling MET Calculator uses the standard MET (Metabolic Equivalent of Task) method to estimate your kilocalorie expenditure in seconds.
Enter your weight, choose an intensity that matches your typical speed or perceived effort, and set your ride duration. You will get total calories burned plus useful breakdowns such as calories per minute, calories per hour, and how long it takes to burn 100 kcal. The calculator also shows the exact formula so you can understand and verify the estimate.
Whether you ride for fitness, commute to work, or train for a century, this tool is a practical starting point for tracking energy balance, planning nutrition, and comparing ride intensities.

How to Use This Tool
Start by entering your body weight in the first field and choose whether you are entering kilograms or pounds — the calculator converts pounds to kilograms automatically using the factor 0.45359237. Next, select the intensity option that best matches your ride. The dropdown lists the standard MET values from the Compendium of Physical Activities, ranging from a leisurely 4.0 MET cruise to a racing effort of 15.8 MET. If you know a more precise MET value — for example from a cycling power meter or a previous fitness assessment — you can override the dropdown by typing it into the Custom MET field.
Then set your ride duration in minutes or hours. A row of quick-set buttons (15, 30, 45, 60 minutes) lets you fill common ride lengths with one click. Press Calculate and the results panel shows your estimated total calorie burn, calories per minute, calories per hour, and how long it would take to burn 100 kcal at that same effort. Use the Reset button to clear all fields and start over whenever you want to compare a different scenario.
How the Formula Works
The calculator uses the standard metabolic equivalent method from exercise physiology. One MET is defined as the resting metabolic rate: approximately 3.5 mL of oxygen consumed per kilogram of body mass per minute, which is roughly 1 kcal per kilogram per hour. When you cycle at 8 METs, your body consumes oxygen at about eight times the resting rate.
Total calories = Calories per minute × ride duration (minutes)
The factor 200 in the denominator comes from the energy equivalent of oxygen: burning 1 liter of oxygen releases approximately 5 kcal, so the constants in the equation combine into the familiar kcal/min formula used by exercise scientists. Because the formula uses body weight, heavier riders burn more calories at the same speed — which is why two cyclists riding side by side can have very different energy expenditures.
The MET values themselves are drawn from the Compendium of Physical Activities, a joint project of Arizona State University and the National Cancer Institute that classifies the energy cost of hundreds of physical activities using standardized codes and MET intensities. The compendium is the reference most fitness calculators and research studies rely on.
Reference MET Values for Cycling
The table below shows the MET values used in this calculator, based on the Compendium of Physical Activities. Speed is only a rough guide: wind, hills, bike weight, tire pressure, and drafting all change the true effort at any given speed, so treat the descriptions as approximations.
| Pace / Effort | Typical speed | MET |
|---|---|---|
| Leisurely | < 10 mph (16 km/h) | 4.0 |
| Moderate | 10–12 mph (16–19 km/h) | 6.8 |
| Brisk | 12–14 mph (19–22 km/h) | 8.0 |
| Vigorous | 14–16 mph (22–25 km/h) | 10.0 |
| Fast | 16–19 mph (25–30 km/h) | 12.0 |
| Racing | > 20 mph (32 km/h) | 15.8 |
For comparison, walking at a normal pace is about 3.5 MET, jogging is around 7 MET, and running at 6 mph (10 km/h) is roughly 9.8 MET. This helps you see how cycling stacks up against other common activities.
Worked Examples
Calories per minute = 8 × 3.5 × 70 ÷ 200 = 9.8 kcal/min
Total = 9.8 × 45 = 441 kcal
That is roughly the energy in a large banana with a spoonful of peanut butter — a good reminder that a ride also creates an appetite, and post-ride snacks can easily offset the calories you just burned if you are not paying attention.
Calories per minute = 6.8 × 3.5 × 90 ÷ 200 = 10.71 kcal/min
Total = 10.71 × 30 = 321 kcal
Notice that the heavier rider burns meaningfully more calories for the same effort and duration. That is why body weight is the first input in the calculator and why weight is the biggest single variable in the MET equation.
Tips and Limitations
- Use heart-rate or power data for more personalized results.
- Weigh yourself on the same scale at the same time of day for consistent inputs.
- For steady efforts, MET values are most accurate; for interval rides, use a higher average intensity.
- Add roughly 10–20% if your route has significant climbs or strong headwinds.
- Track weekly totals across several rides instead of obsessing over a single estimate.
Frequently Asked Questions
What does MET mean? MET stands for Metabolic Equivalent of Task. One MET equals the energy burned while sitting quietly at rest. Cycling at 8 METs means you are burning about eight times more energy than at rest, which is why higher MET values produce much higher calorie numbers.
Does bike type matter? Yes. The MET values above assume a standard bicycle on level ground. Mountain biking, riding uphill, or commuting on a heavy bike raises the true effort, while riding in a pace line or on an aerodynamic road bike can lower it.
Can I use this for stationary cycling? Absolutely. Choose the moderate or vigorous option depending on resistance and cadence. Indoor cycling classes typically average 7–9 MET, so the Brisk or Vigorous presets are usually the best match.
How accurate is the estimate? For a healthy adult riding a steady pace on flat ground, the MET method is usually within about 10–20% of indirect calorimetry measurements. Individual variation, fitness level, and riding conditions explain most of the gap.
