Exercise Calorie Calculator

Example Data Table

These example values assume a 70 kg person exercising for 30 minutes at standard effort and zero incline.

Exercise	MET	Duration	Weight	Estimated Calories
Walking, brisk	4.3	30 min	70 kg	158.0 kcal
Cycling, moderate	7.5	30 min	70 kg	275.6 kcal
Running, 6 mph	9.8	30 min	70 kg	360.2 kcal
Yoga	2.5	30 min	70 kg	91.9 kcal
HIIT circuit	10.5	30 min	70 kg	385.9 kcal

Formula Used

This calculator uses the standard MET calorie equation, then adjusts the exercise value using effort and optional incline.

Effective MET = Base MET × Effort Multiplier × Incline Multiplier

Gross Calories = Effective MET × 3.5 × Weight(kg) ÷ 200 × Minutes

Net Active Calories = (Effective MET − 1) × 3.5 × Weight(kg) ÷ 200 × Minutes

Pace = Minutes ÷ Distance

MET represents how hard an activity is compared with resting energy use.
Gross calories include total session energy burn.
Net calories remove the resting baseline and show active burn only.
Incline multiplier helps estimate extra demand during uphill or treadmill incline work.
Heart-rate zone is informational and does not directly change calories here.

FAQs

1. What does MET mean in this calculator?

MET means metabolic equivalent of task. One MET is resting energy use. Higher MET values represent harder activities and greater calorie burn per minute.

2. Are the calorie results exact?

No. They are practical estimates. Real calorie burn changes with fitness level, movement efficiency, body composition, temperature, terrain, and workout technique.

3. Why are gross and net calories different?

Gross calories reflect total session energy use. Net calories subtract resting burn, so they show the extra calories tied more directly to exercise effort.

4. Should I use custom MET values?

Use custom MET only when you have a trusted source, such as lab data, coaching tables, or a research reference for your exact activity style.

5. Does incline matter for every exercise?

Incline is most useful for treadmill walking, running, hiking, or hill work. Leave it at zero for flat workouts or activities where grade is irrelevant.

6. Why enter distance if duration already exists?

Distance helps calculate pace, speed, and calorie cost per kilometer or mile. It adds better training context, especially for walking, running, hiking, and cycling.

7. How is the heart-rate zone used here?

It provides extra session insight. The calculator estimates your zone from age and average heart rate, but it does not replace clinical or sports testing.

8. Can I use this for nutrition planning?

Yes. It can help estimate workout energy needs, compare sessions, and support meal timing decisions. Still match results with your broader calorie targets.
