Enter your HIIT time and body weight to calculate your calories burned doing HIIT. Most HIIT workouts burn about 8 to 17 calories per minute, with harder intervals and heavier body weights driving the total higher.
HIIT Calories Burned Formula
HIITC = BW_{lb} \times T \times FBasic mode uses the standard HIIT factor. Advanced mode lets you choose a factor that better matches the way you trained.
- HIITC = calories burned
- BWlb = body weight in pounds
- T = HIIT time in minutes
- F = HIIT factor
| Session Style | HIIT Factor |
|---|---|
| Beginner intervals | 0.048 |
| Standard HIIT | 0.064 |
| Hard intervals | 0.079 |
| Sprint / Tabata style | 0.095 |
HIIT by the Numbers
- Most HIIT sessions last 10 to 30 minutes.
- Work intervals are commonly 10 to 60 seconds long.
- Recovery intervals are commonly 10 to 90 seconds long.
- A 150 lb person doing standard HIIT burns about 96 calories in 10 minutes.
- A 200 lb person doing standard HIIT burns about 128 calories in 10 minutes.
HIIT Calories Burned by Body Weight and Time
The table below uses the standard HIIT factor from basic mode.
| Body Weight | 10 min | 20 min | 30 min |
|---|---|---|---|
| 120 lbs | 77 | 154 | 230 |
| 150 lbs | 96 | 192 | 288 |
| 180 lbs | 115 | 230 | 346 |
| 200 lbs | 128 | 256 | 384 |
| 220 lbs | 141 | 282 | 422 |
| 250 lbs | 160 | 320 | 480 |
Calories Per Minute by HIIT Style
| Session Style | 150 lb Person | 200 lb Person | Typical Feel |
|---|---|---|---|
| Beginner intervals | 7.2 kcal/min | 9.6 kcal/min | Longer recoveries, lower density |
| Standard HIIT | 9.6 kcal/min | 12.8 kcal/min | Balanced work and recovery |
| Hard intervals | 11.9 kcal/min | 15.8 kcal/min | Shorter recovery, higher output |
| Sprint / Tabata style | 14.3 kcal/min | 19.0 kcal/min | Very dense max-effort bursts |
What Changes Your HIIT Calorie Burn?
The biggest drivers are session length, body weight, interval density, and exercise choice. Running sprints, air bike work, rowing, burpees, jump squats, and other explosive movements usually sit near the top of the range. Sessions with longer recoveries or lower-impact movements sit lower. Short rest periods keep heart rate high for more of the workout, which raises calories per minute.
For the cleanest input, count the main interval block of your workout. If your session includes a warm-up and cool-down, leave those out. Short recovery periods inside the timed interval block can stay included.
FAQs
Is basic mode enough for most users?
Yes. If you did a normal HIIT class, circuit, bike interval session, or bodyweight interval workout, basic mode is the fastest option and uses the standard HIIT pace factor.
When should I use advanced mode?
Use advanced mode if your session was clearly easier than normal HIIT, or if it was much harder, such as sprint intervals or Tabata-style rounds with very short rest.
How many calories does 20 minutes of HIIT burn?
At the standard HIIT pace, a 150 lb person burns about 192 calories in 20 minutes, while a 200 lb person burns about 256 calories. Harder interval styles push those numbers higher.
Does HIIT burn more per minute than steady cardio?
Usually yes. HIIT packs more work into each minute, especially when the recoveries are short and the movements are explosive or full-body.
