Concept 2 Calorie Calculator
Tracking calories burned during exercise can help you understand your workout intensity, monitor fitness progress, and plan your training routine. Whether you’re using a Concept2 rowing machine, SkiErg, or BikeErg, estimating your energy expenditure can provide useful information about your exercise sessions.
Our free Concept2 Calorie Calculator helps you estimate how many calories you burn during indoor rowing, SkiErg, and BikeErg workouts. By entering your body weight, workout duration, and exercise intensity, you can quickly calculate your estimated calorie expenditure.
The calculator supports different intensity levels, including easy, moderate, hard, and very hard workouts. It also allows you to enter the calories displayed on your Concept2 Performance Monitor to compare the monitor reading with your estimated calorie expenditure.
Unlike a basic exercise calorie calculator, this tool provides additional information, including calories burned per minute and estimated calories burned per hour.
These measurements can help you compare workouts, understand how exercise duration affects calorie expenditure, and track your training sessions.
Whether you’re a beginner learning indoor rowing or an experienced athlete using Concept2 equipment for cardiovascular training, this calculator offers a convenient way to estimate workout calories.
However, it’s important to understand that this calculator provides approximate calorie estimates using MET-based formulas, not official Concept2 Performance Monitor calculations. Actual energy expenditure depends on factors such as power output, technique, body composition, and individual physiology.
What Is a Concept2 Calorie Calculator?
A Concept2 Calorie Calculator is an online fitness tool designed to estimate the number of calories burned during workouts performed on Concept2-style exercise equipment.
Concept2 manufactures popular indoor training machines, including the RowErg, SkiErg, and BikeErg.
These machines are commonly used for cardiovascular exercise, endurance training, fitness testing, and structured athletic workouts.
Our calculator estimates calorie expenditure using four primary factors:
- Workout Type: Indoor rowing, SkiErg, or BikeErg.
- Body Weight: Your weight in pounds or kilograms.
- Workout Duration: The total time spent exercising.
- Workout Intensity: Easy, moderate, hard, or very hard.
The calculator uses estimated Metabolic Equivalent of Task (MET) values to determine energy expenditure.
MET values represent the approximate energy cost of physical activities relative to resting metabolic expenditure.
By combining the selected MET value with body weight and exercise duration, the calculator estimates the total calories burned.
It also provides an optional feature for comparing your estimated calorie expenditure with the calorie reading shown on your Concept2 monitor.
How to Use the Concept2 Calorie Calculator
Our free online Concept2 Calorie Calculator is designed to make workout calorie estimation quick and convenient.
Follow these steps to calculate your estimated calories burned.
Step 1: Select Your Workout Type
Start by choosing the type of exercise you’re performing.
The calculator provides three workout options:
Indoor Rowing: Select this option if you’re exercising on a Concept2 rowing machine or RowErg.
SkiErg: Choose this option if you’re using a Concept2 SkiErg machine.
BikeErg: Select this option if you’re performing a cycling workout on a Concept2 BikeErg.
Each activity uses different estimated MET values depending on the selected workout intensity.
Selecting the correct activity helps the calculator apply the appropriate energy expenditure estimate.
Step 2: Enter Your Body Weight
Next, enter your current body weight.
You can choose between:
- Pounds (lb)
- Kilograms (kg)
For example, if you weigh 175 pounds, enter 175 and select lb.
If you weigh 80 kilograms, enter 80 and select kg.
The calculator automatically converts pounds into kilograms when necessary.
Body weight matters because the MET-based formula estimates energy expenditure partly based on a person’s mass.
At the same selected MET intensity and duration, a person with a higher body weight generally receives a higher estimated calorie result.
Step 3: Enter Your Workout Duration
Enter the length of your exercise session using the minutes and seconds fields.
For example, if you completed a 30-minute rowing workout, enter:
Minutes = 30
Seconds = 0
If your workout lasted 25 minutes and 30 seconds, enter:
Minutes = 25
Seconds = 30
The calculator supports durations greater than zero, with a maximum minutes entry of 1,440 and seconds between 0 and 59.
Using both minutes and seconds allows you to estimate calories for workouts with more precise durations.
Step 4: Select Your Workout Intensity
Choose the intensity that best describes your exercise session.
The calculator provides four options:
Easy: Light exercise performed at a comfortable effort.
Moderate: Steady exercise requiring noticeable effort while remaining manageable.
Hard: Vigorous exercise requiring greater cardiovascular and muscular effort.
Very Hard: High-intensity exercise performed at a demanding effort level.
The selected intensity determines the MET value used in the calculation.
For example, moderate indoor rowing uses an estimated MET value of 7.0, while very hard rowing uses 12.0.
These are illustrative assumptions rather than measurements of your actual power output.
Step 5: Enter Monitor Calories (Optional)
If your Concept2 Performance Monitor displays a calorie reading, you can enter that value in the optional field.
For example:
Monitor Calories = 300
The calculator compares this reading with its own estimated calorie expenditure.
This feature is useful for understanding how a general MET-based estimate differs from the monitor’s calculation.
You can leave this field empty if you don’t have a monitor reading.
Step 6: Click Calculate
After entering your workout information, click the Calculate button.
The calculator displays:
- Estimated calories burned
- Total workout duration
- Calories burned per minute
- Estimated calories burned per hour
- Monitor calories, if entered
- Difference between estimated and monitor calories
These results provide a summary of your estimated workout energy expenditure.
Step 7: Reset the Calculator
To calculate calories for another workout, click the Reset button.
This clears the previous inputs and results and restores the initial settings.
You can then enter new workout information.
Concept2 Calorie Calculator Formula
Our Concept2 calories burned calculator uses a MET-based energy expenditure formula.
MET stands for Metabolic Equivalent of Task.
One MET represents an approximate resting metabolic rate.
Higher MET values indicate activities with greater estimated energy demands.
The calculator uses the following formula:
Calories Burned = MET × Body Weight (kg) × Workout Duration (hours)
This formula provides an approximation of gross energy expenditure during exercise.
Gross energy expenditure includes the estimated energy your body would use at rest during the same period.
Understanding Each Formula Component
MET Value: Represents the estimated intensity of the selected activity.
Body Weight: Your weight converted into kilograms.
Workout Duration: The total exercise time expressed in hours.
For example, a 30-minute workout equals 0.5 hours.
By multiplying these values, the calculator estimates total calories burned.
Formula for Calories Burned per Minute
The calculator also determines the average estimated calorie expenditure per minute.
Calories per Minute = Total Estimated Calories ÷ Workout Duration (Minutes)
This helps you compare the estimated calorie rate across different workouts.
Formula for Calories Burned per Hour
To estimate hourly energy expenditure, use:
Calories per Hour = Calories per Minute × 60
This value represents the estimated calorie expenditure if the same intensity were maintained for one hour.
It does not mean that every person can sustain that intensity for 60 minutes.
Formula for Monitor Calorie Difference
If you enter the calories displayed by your Concept2 monitor, the calculator determines the difference.
Calorie Difference = Estimated Calories − Monitor Calories
A positive result means the calculator’s estimate is higher than the monitor reading.
A negative result means the calculator’s estimate is lower than the monitor reading.
Concept2 Calorie Calculator Example
Let’s calculate the estimated calories burned during a moderate indoor rowing workout.
Example Workout Details
Suppose a person completes a workout with these measurements:
Workout Type: Indoor Rowing
Body Weight: 180 pounds
Workout Duration: 30 minutes
Workout Intensity: Moderate
Monitor Calories: 300 kcal
Step 1: Convert Pounds to Kilograms
The calculator uses kilograms for its energy expenditure formula.
The conversion formula is:
Weight (kg) = Weight (lb) × 0.45359237
Weight = 180 × 0.45359237
Weight = 81.65 kg
Step 2: Convert Workout Duration to Hours
Workout Duration = 30 minutes
Duration in Hours = 30 ÷ 60
Duration = 0.5 hours
Step 3: Identify the MET Value
For moderate indoor rowing, the calculator uses:
MET = 7.0
Step 4: Calculate Estimated Calories Burned
Calories = MET × Weight × Duration
Calories = 7.0 × 81.65 × 0.5
Calories = 285.77
Estimated Calories Burned = 286 kcal
Step 5: Calculate Calories per Minute
Calories per Minute = 285.77 ÷ 30
Calories per Minute = 9.5 kcal/min
Step 6: Calculate Calories per Hour
Calories per Hour = 9.5255 × 60
Estimated Calories per Hour = 572 kcal/hr
Step 7: Compare Monitor Calories
Suppose your Concept2 monitor displays 300 calories.
Calorie Difference = 285.77 − 300
Difference = −14.2 kcal
This indicates that the calculator’s estimate is approximately 14.2 calories lower than the monitor reading.

|---|---|
| Workout Type | Indoor Rowing |
| Body Weight | 180 lb |
| Workout Duration | 30 minutes |
| Workout Intensity | Moderate |
| Estimated Calories Burned | 286 kcal |
| Calories per Minute | 9.5 kcal/min |
| Calories per Hour | 572 kcal/hr |
| Monitor Calories | 300 kcal |
| Difference From Monitor | −14.2 kcal |
These results are based on the calculator’s selected MET assumptions.
Actual energy expenditure may differ.
Concept2 Rowing Calories Burned
Indoor rowing is a cardiovascular exercise that involves coordinated movements of the legs, core, and upper body.
The Concept2 rowing calorie calculator estimates calories based on body weight, workout duration, and intensity.
Our calculator uses the following MET values for indoor rowing.
| Rowing Intensity | Estimated MET |
|---|---|
| Easy | 4.8 |
| Moderate | 7.0 |
| Hard | 8.5 |
| Very Hard | 12.0 |
Higher workout intensity results in a higher estimated calorie expenditure.
Calories Burned Rowing for 30 Minutes
Consider a person weighing 70 kilograms.
Using the MET formula:
Calories = MET × 70 × 0.5
The estimated results are:
| Rowing Intensity | Calories in 30 Minutes |
|---|---|
| Easy | 168 kcal |
| Moderate | 245 kcal |
| Hard | 298 kcal |
| Very Hard | 420 kcal |
These estimates assume that the selected intensity is maintained throughout the workout.
Actual results depend on the effort performed.
Concept2 SkiErg Calories Burned
The Concept2 SkiErg simulates movements associated with Nordic skiing.
It involves coordinated upper-body, core, and lower-body activity, depending on technique.
SkiErg workouts can range from comfortable endurance sessions to demanding interval training.
Our SkiErg calorie calculator uses these estimated MET values:
| SkiErg Intensity | Estimated MET |
|---|---|
| Easy | 4.5 |
| Moderate | 7.0 |
| Hard | 9.0 |
| Very Hard | 12.0 |
Calories Burned on SkiErg for 30 Minutes
Suppose a person weighs 80 kilograms.
The formula is:
Calories = MET × 80 × 0.5
Estimated results:
| SkiErg Intensity | Calories Burned |
|---|---|
| Easy | 180 kcal |
| Moderate | 280 kcal |
| Hard | 360 kcal |
| Very Hard | 480 kcal |
These numbers provide approximate energy expenditure estimates for different intensity levels.
They are not official Concept2 SkiErg monitor calculations.
Concept2 BikeErg Calories Burned
The Concept2 BikeErg is an indoor cycling machine used for aerobic conditioning, endurance workouts, and interval training.
Cycling intensity can vary depending on cadence, resistance, and power output.
Our Concept2 BikeErg calorie calculator uses the following MET values:
| BikeErg Intensity | Estimated MET |
|---|---|
| Easy | 4.0 |
| Moderate | 6.8 |
| Hard | 8.8 |
| Very Hard | 11.0 |
Calories Burned on BikeErg for 30 Minutes
Consider a person weighing 75 kilograms.
Calories = MET × 75 × 0.5
Estimated results:
| BikeErg Intensity | Calories Burned |
|---|---|
| Easy | 150 kcal |
| Moderate | 255 kcal |
| Hard | 330 kcal |
| Very Hard | 413 kcal |
These results illustrate how the calculator estimates energy expenditure at different cycling intensities.
Your actual calorie expenditure may differ depending on your sustained power output and individual physiology.
How Many Calories Does Concept2 Rowing Burn in 20, 30, or 60 Minutes?
Workout duration is one of the main factors affecting estimated calories burned.
Longer workouts generally result in greater total energy expenditure when the same intensity is maintained.
The following examples assume:
Body Weight = 70 kg
Workout Type = Indoor Rowing
Intensity = Moderate
MET = 7.0
| Workout Duration | Estimated Calories |
|---|---|
| 10 Minutes | 82 kcal |
| 15 Minutes | 123 kcal |
| 20 Minutes | 163 kcal |
| 30 Minutes | 245 kcal |
| 45 Minutes | 368 kcal |
| 60 Minutes | 490 kcal |
For example, a 70 kg person performing moderate indoor rowing for 60 minutes would have an estimated gross energy expenditure of 490 calories.
These estimates assume a consistent intensity throughout the workout.
During real workouts, effort often changes because of rest periods, intervals, fatigue, and pacing.
Concept2 Monitor Calories vs. Calculator Calories
One common question among Concept2 users is why the calories displayed on the Performance Monitor may differ from estimates provided by online calorie calculators.
The difference occurs because the calculations use different methods.
Concept2 Performance Monitor Calories
Concept2 Performance Monitors calculate exercise-related performance metrics using machine-specific measurements and algorithms.
Monitor calorie values are based on the machine’s performance calculations and standardized assumptions.
They are not direct measurements of an individual’s metabolic energy expenditure.
MET-Based Calculator Calories
Our calculator estimates calories using:
- Body weight
- Exercise duration
- Workout type
- Selected intensity
It does not directly measure watts, pace, stroke rate, or mechanical power output.
As a result, two people with different body weights may receive different calculator estimates even if their machine performance is identical.
Why Results May Differ
Differences can occur because of:
Power Output: The monitor uses machine performance information, while this calculator uses selected intensity categories.
Body Weight: Our calculator directly incorporates body weight into its estimate.
Exercise Intensity: The selected intensity may not accurately represent the workout’s actual energy demand.
Individual Physiology: Exercise efficiency and metabolic responses vary between individuals.
Workout Structure: Interval workouts may involve changing intensity levels that a single MET selection cannot fully represent.
The comparison feature is intended to show the numerical difference between the two values, not determine which one represents your exact calorie expenditure.
What Affects Calories Burned During Concept2 Workouts?
Several factors influence actual calorie expenditure during rowing, SkiErg, and BikeErg workouts.
1. Body Weight
Body weight is included directly in the calculator’s MET-based formula.
At the same MET value and duration, a heavier person receives a higher estimated calorie result.
However, actual energy expenditure also depends on power output and exercise efficiency.
2. Workout Intensity
Exercise intensity strongly influences calorie expenditure.
Harder workouts generally require more energy per minute than easier workouts.
Our calculator uses four intensity categories to represent different estimated energy demands.
3. Workout Duration
Longer sessions typically produce greater total calorie expenditure when intensity remains unchanged.
For example, rowing for 60 minutes at a consistent effort generally requires more total energy than rowing for 20 minutes at the same effort.
4. Power Output
Power output, commonly measured in watts, represents the rate of mechanical work performed.
Higher sustained power output generally requires greater metabolic energy expenditure.
However, our calculator does not use watts as an input.
5. Exercise Technique
Rowing, skiing, and cycling technique can influence mechanical efficiency and exercise performance.
Two people producing similar machine outputs may expend different amounts of metabolic energy.
6. Fitness Level
Training experience and cardiovascular fitness can influence how efficiently a person performs exercise.
Fitness level may also affect how long someone can sustain a particular intensity.
7. Workout Structure
Steady-state workouts and interval workouts have different intensity patterns.
A session containing repeated high-intensity efforts and rest periods may not be accurately represented by one intensity selection.
For mixed-intensity sessions, calculating separate workout segments can provide a more informative approximation.
How to Estimate Calories During Interval Workouts
Interval training involves alternating between higher-intensity exercise and recovery periods.
For example, a rowing workout might include:
10 minutes of moderate rowing
5 minutes of hard rowing
5 minutes of easy rowing
Instead of treating the entire workout as one intensity, you can estimate each section separately.
Suppose the person weighs 70 kilograms.
Moderate Rowing
Duration = 10 minutes
MET = 7.0
Calories = 7 × 70 × (10 ÷ 60)
Calories ≈ 81.7 kcal
Hard Rowing
Duration = 5 minutes
MET = 8.5
Calories = 8.5 × 70 × (5 ÷ 60)
Calories ≈ 49.6 kcal
Easy Rowing
Duration = 5 minutes
MET = 4.8
Calories = 4.8 × 70 × (5 ÷ 60)
Calories = 28 kcal
Total Estimated Calories
Total = 81.7 + 49.6 + 28
Total Estimated Calories ≈ 159 kcal
This approach can provide a more detailed approximation for workouts involving different intensity levels.

Tips for Getting Better Calorie Estimates
Although no simple exercise calculator can measure exact calorie expenditure, careful inputs can improve the usefulness of your results.
Enter Your Current Weight: Use a reasonably recent body weight measurement.
Choose the Correct Activity: Select rowing, SkiErg, or BikeErg based on the machine used.
Record Accurate Workout Duration: Include the actual time spent exercising.
Select a Realistic Intensity: Choose an intensity that reflects your effort rather than the intensity you intended to maintain.
Consider Rest Periods: For interval workouts, calculate different exercise segments separately when practical.
Use Monitor Readings for Comparison: If available, enter your Concept2 monitor calories to compare the results.
Track Trends Consistently: Using the same estimation method over time can help you compare similar workout sessions.
Remember that calorie estimates are approximations and should not be treated as exact measurements of energy expenditure.
Common Mistakes When Calculating Concept2 Calories
One common mistake is assuming that calorie values shown by exercise machines represent exact personal calorie expenditure.
Machine readings are estimates based on standardized calculations.
Another mistake is selecting a workout intensity that does not match the actual session.
For example, choosing very hard intensity for a comfortable rowing workout can substantially overestimate calories.
Incorrect body weight units can also affect the calculation.
Entering pounds while selecting kilograms produces an inaccurate result.
Some people also confuse calories burned per hour with total workout calories.
If a calculator displays 600 calories per hour, that does not mean a 20-minute workout burned 600 calories.
At a constant rate of 600 calories per hour, a 20-minute workout would correspond to approximately 200 calories.
Finally, remember that this calculator estimates gross energy expenditure rather than calories burned above resting expenditure alone.
