Calories Burned By Heart Rate Calculator
Estimate calories burned from heart rate, age, weight, and exercise duration.
Calories Burned Based on Heart Rate
Heart rate during exercise reflects oxygen consumption, which directly relates to calorie expenditure. This calculator uses sex-specific formulas from exercise physiology research to estimate calories burned from your average heart rate, age, weight, and workout duration. For activity-based estimates without a heart-rate monitor, try the Calories Burned Calculator.
Heart Rate Calorie Formulas
Without VO₂ max, men use: CB = T × (0.6309×H + 0.1988×W + 0.2017×A − 55.0969) / 4.184. Women use: CB = T × (0.4472×H − 0.1263×W + 0.074×A − 20.4022) / 4.184. T is duration in minutes, H is average heart rate in bpm, W is weight in kg, and A is age in years. If you know your VO₂ max, more accurate gender-specific formulas are applied automatically.
Why Heart Rate Matters
Higher heart rates during exercise indicate greater oxygen demand and typically higher calorie burn per minute. A resting heart rate of 60–100 bpm is normal for healthy adults; during vigorous exercise, rates of 150–180 bpm are common. Tracking heart rate gives a personalized estimate that adjusts for fitness level better than MET tables alone.
Frequently Asked Questions
How do I calculate calories burned from heart rate?
Enter sex, age, weight, average heart rate during exercise, and duration in minutes. The calculator applies the Keytel et al. formulas to estimate total kilocalories burned.
Does a higher heart rate burn more calories?
Generally yes. Higher heart rates during exercise correlate with greater oxygen consumption and therefore more calories burned per minute, assuming the elevated rate reflects genuine exertion.
What is a normal resting heart rate?
For healthy adults, a normal resting heart rate is 60 to 100 beats per minute. Athletes may have resting rates below 60 bpm. Rates outside this range should be discussed with a healthcare provider.
Should I enter my VO₂ max?
If you know your VO₂ max from a lab test or field estimate, enable the VO₂ max option for improved accuracy. Otherwise, the standard formulas without VO₂ max provide a good estimate for most people.
How do I measure my exercise heart rate?
Use a chest strap, wrist monitor, or smartwatch during your workout. Alternatively, count beats at your wrist for 15 seconds and multiply by four to get beats per minute.
