Stationary exercise is one of the most approachable ways to build consistent low-impact movement. Whether you are pedaling a stationary bike, working a rowing machine, or following a mat-based yoga session, the movement stays in one place while your body still gets a meaningful workout. This calculator estimates the calories you burn in a single session using your body weight, session length, and the intensity of the activity.
It uses the standard MET (metabolic equivalent) method, which compares the energy cost of an activity with your resting metabolic rate. You simply choose the closest match to your workout, enter your weight and time, and the calculator returns a calorie estimate along with a clear breakdown of the numbers behind it.
Use it to plan low-impact cardio, gauge the calorie side of a gentle movement practice, or compare how different stationary activities add up across a week of training.

Step-by-Step Guide
Using the calculator is straightforward:
- Select the stationary activity that best matches your session from the dropdown. Each activity has an assigned MET value based on published compendium data.
- Enter your body weight. The calculator works with pounds or kilograms and converts automatically.
- Enter the session length in minutes or hours. Use the quick-fill chips for common sessions of 15, 30, 45, or 60 minutes.
- If you know a different MET value for your exact pace or machine resistance, tick “Use custom MET value” and type it in.
- Press Calculate to see your estimated calories, along with the MET, duration, and body weight used in the calculation.

The Formula Explained
This calculator uses the standard metabolic equivalent (MET) method:
Calories = MET × body weight (kg) × duration (minutes) × 0.0175
One MET is the energy you use while sitting quietly. During exercise, the MET value tells you how many times harder your body is working than at rest. For example, moderate stationary cycling at 6.8 MET means your energy expenditure is 6.8 times your resting rate.
The constant 0.0175 comes from the common assumption that resting oxygen consumption is about 3.5 mL of oxygen per kilogram of body weight per minute, and that each liter of oxygen consumed equals roughly 5 kcal. Factoring in the conversion from minutes produces the 0.0175 coefficient. MET values used here are adapted from the Compendium of Physical Activities, a widely cited research resource for exercise energy cost.
Worked Examples
Example 1: Moderate stationary cycling
A 68 kg (150 lb) adult rides a stationary bike at a moderate effort for 30 minutes. The MET value is 6.8.
Calories = 6.8 × 68 × 30 × 0.0175 = 242.8 kcal
Example 2: Gentle mat-based yoga
An 80 kg (176 lb) adult does 45 minutes of gentle yoga (MET 2.5).
Calories = 2.5 × 80 × 45 × 0.0175 = 157.5 kcal
Notice how duration and body weight both matter as much as intensity. A heavier person burns more calories at the same activity because moving more mass takes more energy.
Reference MET Values
The dropdown uses these common values for stationary, low-impact sessions:
| Activity | MET |
|---|---|
| Stationary cycling — very light effort | 3.5 |
| Stationary cycling — light effort | 4.8 |
| Stationary cycling — moderate effort | 6.8 |
| Stationary cycling — vigorous effort | 8.8 |
| Recumbent cycling — moderate effort | 4.0 |
| Rowing machine — light effort | 3.5 |
| Rowing machine — moderate effort | 4.8 |
| Rowing machine — vigorous effort | 7.0 |
| Mat-based yoga — gentle (hatha) | 2.5 |
| Mat-based yoga — moderate | 3.0 |
| Stretching / mobility work | 2.3 |
If your machine’s display lists watts, you can often find a corresponding MET from the compendium and enter it in the custom MET field for a more personalized result.
Tips & Best Practices
- Use your current body weight, not a goal weight, because the formula is weight-dependent.
- When in doubt between two intensity descriptions, choose the lower one. People tend to overestimate how hard they are working.
- If your stationary bike has a calorie readout, compare it with this calculator. Machine estimates are often optimistic because they do not account for your actual body weight, age, and fitness level.
- Add a few minutes of easy pedaling or stretching to cool down; the calculator can include that if you simply enter the total session time.
- For weight management, use the result as a rough guide, not an exact bank balance. A 200 kcal estimate can vary by 20-30 kcal either way.
Limitations & Accuracy Notes
The MET formula gives an average estimate based on group data. Individual calorie burn depends on body composition, muscle mass, efficiency, genetics, and how faithfully you sustain the intensity. A trained cyclist may burn less at the same wattage because their body is more efficient, while a beginner may burn slightly more. The calculator also does not adjust for age or sex, which play a smaller but real role in energy expenditure.
Treat the output as a planning tool, not a medical measurement. For general physical activity guidance, the CDC’s physical activity basics page is a reliable reference. If you use a heart-rate monitor, it may provide a complementary estimate, but remember that both methods are approximations.
