Medical disclaimer: This calculator provides an estimate only and is for informational and educational purposes only. It is not a medical device and is not a substitute for professional medical advice, diagnosis, or treatment.
Individual calorie expenditure can vary based on fitness level, body composition, illness, medications, stress, hydration, exercise conditions, and heart rate measurement accuracy. Consult a qualified healthcare professional before making medical, dietary, or training decisions.
This calculator estimates calories burned during exercise by combining your average heart rate, age, body weight, and exercise duration.
Heart rate can help reflect exercise intensity, which is why it is often used in calorie-burn estimation formulas.
The result is best treated as an approximation rather than an exact measure of energy expenditure.
| Age | Weight | Heart Rate | Duration | Estimated Calories |
|---|---|---|---|---|
| 30 | 160 lbs | 140 BPM | 60 min | 770.155308 |
| 25 | 140 lbs | 130 BPM | 45 min | 430.930793 |
| 40 | 180 lbs | 150 BPM | 30 min | 390.570885 |
Weight is converted internally from pounds to kilograms using 1 kg = 2.205 lbs.

No. This calculator provides an estimate based on a published heart-rate formula and the values you enter.
The formula uses different coefficients for male and female inputs.
This calculator accepts pounds for convenience, then converts weight to kilograms before applying the formula.
Use your average exercise heart rate in beats per minute for the workout you want to estimate.
Yes. Many factors can influence heart rate and therefore affect the estimate.
You can use it for many activities as long as you have a reasonably accurate average heart rate reading.
The output is only as reliable as the heart rate data entered.
