Calories Burned Yoga Calculator

The MET formula behind the estimate

One line does the work: kcal per minute = MET x 3.5 x body weight in kilograms / 200. The 3.5 is the oxygen cost of resting in milliliters per kilogram per minute, the 200 converts that oxygen into kilocalories, and the MET says how many times harder the pose work is than sitting still. Convert pounds first: 150 / 2.20462 = 68.04 kg.

Hatha yoga carries 2.3 METs in the 2024 Adult Compendium, so a 150 lb practitioner spends 2.3 x 3.5 x 68.04 / 200 = 2.74 kcal per minute on it. An hour comes to about 164 calories. Power yoga at 4.0 METs costs 4.76 per minute, which is 286 over the same hour.

The output is gross energy, so it includes the calories you would burn anyway. Of that 164 in the Hatha hour, roughly 71 are the resting baseline, and the movement itself adds about 93. That matters when yoga is pitched as a fat burner, because 93 calories is a small apple, not a meal.

MET values for each yoga style in the 2024 Compendium

The 2024 Adult Compendium of Physical Activities gives yoga its own set of measured entries, and the values run lower than the 2011 estimates most calculators still quote (2024 Adult Compendium of Physical Activities). Hatha dropped from an estimated 2.5 to a measured 2.3, and Vinyasa landed at 2.7, well below the 4.0 to 5.0 figures some sites still print.

Two entries deserve a note. Hot yoga at 3.0 METs is only about 30 percent above Hatha, because heat raises heart rate and sweat without raising the oxygen cost of holding the pose. And high intensity Hatha at 8.0 METs describes a hard, continuous ashtanga style session, not an ordinary studio class, so most practitioners should not use it as their default.

Body weight scales the burn in a straight line

The formula multiplies by kilograms and nothing else personal, so weight moves the total exactly in proportion. A 180 lb practitioner carries 50 percent more mass than a 120 lb one and burns 50 percent more per minute at the same style: 3.29 against 2.19 kcal per minute in Hatha. The grid below shows a full hour of each style across common body weights.

Style and weight trade off in a useful way. A 120 lb person in Power yoga burns 229 an hour, just under the 241 a 220 lb person burns in Hatha, so a lighter practitioner who wants the burn should pick a stronger style rather than add minutes of slow flow. Within one style, the lever that moves the number is body weight, since the MET band is fixed.

Class length: 30, 60, 75 and 90 minutes

Studio classes run longer than gym blocks, and the estimate scales straight with minutes as long as the work stays steady. The table holds body weight at 150 lb and moves only the class length.

Rest breaks shave the total, because the formula prices the whole block at one MET. A class with a long savasana and several seated explanations is closer to 50 minutes of work inside a 75 minute slot, and the honest input is the moving time, not the schedule. Count the held poses and flows, and enter the minutes you spent in them.

What yoga counts as in the activity guidelines

The CDC draws the moderate band at 3.0 to 5.9 METs and the vigorous line at 6.0, and it names Vinyasa and power yoga among its examples of moderate activity (CDC, measuring physical activity intensity). By those bands Hatha at 2.3 METs is light activity, Hot yoga at 3.0 and Power yoga at 4.0 are moderate, and only a continuous high intensity style at 8.0 reaches vigorous.

That makes Power yoga useful for the 150 minute weekly target (CDC activity recommendations): two 60 minute classes and a 30 minute session cover the whole week as moderate work. Hatha does not count toward the target by itself, though it still burns 164 calories an hour at 150 lb and trains balance and flexibility that nothing else in most people's week touches.

For comparison, a 150 lb person walking at 3.0 METs burns about 214 calories in the hour that Hatha burns 164, and a brisk walk near 3.8 METs reaches about 271, above every ordinary yoga style except Power. That surprises people who think of their sweating hour in a 95 degree room as the harder session.

Why the hot room feels harder than it burns

Heart rate and calorie burn part ways in a hot room. The body ships blood to the skin to dump heat, the heart beats faster to move that blood, and sweat pours out, so a wearable that estimates from heart rate will credit you for work the muscles are not doing. Measured oxygen cost, which is what a MET value captures, stays near 3.0 for a standard hot yoga flow against 2.3 for the same flow in a cool room.

That is roughly a 30 percent premium, not the doubling a tracker can show. At 150 lb the honest figure is 214 calories for an hour of Hot yoga against 164 for Hatha, a difference of 50, not 150. Drink the water, expect the high heart rate, and do not treat the watch number as progress against the deficit math.

Sauna suits and heated rooms add no fat burning either. Weight lost in the room is water, and it returns with the first bottles you drink afterward. The 2024 Compendium's measured 3.0 value for Hot yoga is the number to plan around, and it is one of the more useful corrections in the whole update.

Yoga and weight loss: what the numbers allow

Run the arithmetic before you rely on yoga alone. Five hours of Power yoga a week at 150 lb burns about 1,429 calories, which is under half a pound of fat. Five hours of Hatha burns about 822. A pound of fat holds roughly 3,500 calories, so even a devoted practice moves the scale slowly unless the diet side carries the deficit.

That is not a case against the mat. Yoga's real returns show up in adherence, joint health and stress, and a practice you keep for years beats a boot camp you quit in March. Pair the hours with a planned deficit, and let a calorie deficit calculator decide how much of the gap comes from food rather than from extra sun salutations.

One practical boost exists inside the formula itself: Surya Namaskar at 3.5 METs sits between Vinyasa and Power, so a class built around continuous sun salutations burns about 250 calories an hour at 150 lb while still feeling like flow rather than grind.

What the formula cannot see

The equation prices steady work at one fixed MET. It cannot see how deep you hold a pose, how much you shake in a long chair, or whether your teacher built the class around continuous flow or long rest holds. Two people in the same 60 minute Power class can differ by 20 percent or more in real energy cost while the formula gives both of them 286.

It also ignores the small after burn that follows a hard session, which is real but modest, and it cannot price the strength work. Isometric holds build muscle without burning many calories, so a strength gains picture and a calorie burn picture will disagree about the same hour.

Wrist trackers add their own drift, mostly through heart rate as covered above. Use the formula to plan a week, use the tracker to see trends inside your own sessions, and let the mirror and the weights you lift settle whether the practice is doing its job.
