Estimate HIIT calories burned from workout time, body weight and intensity (standard HIIT by default), or find how long to train to burn a calorie goal.

Count the interval block, including short recoveries; leave out warm-up and cool-down.

kcal per lb of body weight per minute, about 6, 8, 10 and 12 METs. Standard HIIT fits a typical class or circuit.

Afterburn (EPOC)
Extra calories burned for a few hours after intense intervals, added on top of the workout.

HIIT Calories Burned Formula

HIITC = BWlb × T × F

The calculator uses the standard HIIT factor by default; choose another intensity to better match 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.

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 the default intensity enough for most users?

Yes. If you did a normal HIIT class, circuit, bike interval session, or bodyweight interval workout, the default Standard HIIT intensity is the fastest option.

When should I change the intensity?

Change the intensity 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.
