Calories burned hiit calculator
This HIIT calories burned calculator estimates how many calories you burn during a high-intensity interval training workout based on duration, body weight, and overall intensity. It is designed for workouts that alternate short bursts of intense effort with brief recovery periods. Because HIIT places a high demand on both aerobic and anaerobic systems, calorie burn is typically higher than steady-state cardio.

What the HIIT calories burned calculator measures
The calculator estimates total energy expenditure during HIIT by converting interval-based effort into metabolic equivalents (METs). Unlike steady cardio, HIIT involves fluctuating intensity levels, but the calculator applies an averaged MET value that reflects the overall workload of the session.
How HIIT workout inputs are interpreted
The calculation begins with workout duration and body weight, which are essential for estimating calorie burn. Intensity selection plays a particularly important role for HIIT, as it determines how demanding the intervals are assumed to be.
- Workout duration: Total time of the HIIT session, including work and rest intervals.
- Body weight: Higher body weight results in greater calorie expenditure.
- Intensity level: Defines how aggressive the work intervals are on average.
HIIT calorie calculation logic
The HIIT calories burned calculator uses the standard metabolic formula:
Calories burned = MET × body weight (kg) × duration (hours)
Because HIIT includes repeated high-effort intervals, MET values are higher than most steady-state activities. Moderate HIIT sessions typically fall around 8–9 METs, while intense HIIT workouts can exceed 10 METs.
Typical MET values for HIIT intensity
| HIIT intensity | Workout description | Approximate MET |
|---|---|---|
| Light | Longer rest periods, controlled intervals | 6.5 |
| Moderate | Balanced work-to-rest ratio | 8.5 |
| Intense | Short rest, maximal effort intervals | 10.5 |
Example HIIT calorie calculation
For a person weighing 95 lb (43 kg) completing a 1-hour moderate HIIT workout:
Calories = 8.5 MET × 43 kg × 1.0 hour = 366 kcal
For higher-intensity sessions, the calculator increases the MET value, resulting in a higher estimated calorie burn.
Calories burned during HIIT by weight and intensity
| Body weight | Light HIIT (6.5 MET) | Moderate HIIT (8.5 MET) | Intense HIIT (10.5 MET) |
|---|---|---|---|
| 120 lb (54 kg) | 351 kcal/hour | 459 kcal/hour | 567 kcal/hour |
| 160 lb (73 kg) | 474 kcal/hour | 621 kcal/hour | 767 kcal/hour |
| 200 lb (91 kg) | 592 kcal/hour | 774 kcal/hour | 956 kcal/hour |
Assumptions and limitations
This HIIT calorie calculator assumes a consistent interval structure throughout the workout. Actual calorie burn may vary based on exercise selection, rest duration, movement efficiency, and individual fitness level.
