Calories Burned Calculator

This calories burned calculator estimates the energy you use during 98 activities, from walking and cycling to swimming, weight training and mowing the lawn. It uses the MET values published in the 2024 Adult Compendium of Physical Activities. Choose an activity, enter your weight and how long you did it, and press Calculate.

Calories burned formula

Calories per minute = MET × 3.5 × weight in kg ÷ 200 Calories burned = Calories per minute × minutes weight in kg = weight in lb × 0.4536

The formula comes from the American College of Sports Medicine. 3.5 is the oxygen a resting adult uses (3.5 mL per kg of body weight per minute), and dividing by 200 turns that into Calories, because each liter of oxygen releases about 5 Calories.

Example: a 155 lb rider weighs 155 × 0.4536 = 70.31 kg. Cycling at 12 to 13.9 mph is 8.0 METs, so they burn 8 × 3.5 × 70.31 ÷ 200 = 9.84 Calories a minute, and 295 Calories in 30 minutes.

Example: a 180 lb walker (81.65 kg) walking briskly at 3.5 to 3.9 mph (4.8 METs) for 45 minutes burns 4.8 × 3.5 × 81.65 ÷ 200 × 45 = 309 Calories. Of those, 244 are above what they'd have burned sitting still for the same 45 minutes.

Where the MET values come from

Every activity here uses the MET value from the 2024 Adult Compendium of Physical Activities, the reference researchers and health agencies use to estimate the energy cost of activities. Its 2024 update (Herrmann and colleagues, Journal of Sport and Health Science 13, pages 6 to 12, doi:10.1016/j.jshs.2023.10.010) reviewed published measurements for over 1,000 activities. The calculator shows each activity's five-digit Compendium code, so you can look up the original entry. Values aren't changed or blended between activities.

Getting a better estimate

Assumptions and limits: MET values are averages measured in groups of adults; the standard formula assumes a resting rate of 3.5 mL of oxygen per kg per minute, which overestimates burn for many heavier, older or less muscular people and underestimates it for some others. Results aren't adjusted for age, sex, fitness or body fat. This calculator is for general information and planning, not medical advice.

Frequently asked questions

How many Calories does cycling burn?

It depends on your speed and weight. At 12 to 13.9 mph (8.0 METs), a 155 lb (70.3 kg) person burns about 295 Calories in 30 minutes. At 14 to 15.9 mph (10.0 METs) that rises to about 369. A heavier rider burns more at the same speed.

How many Calories does walking burn?

Brisk walking at 3.5 to 3.9 mph is 4.8 METs. A 180 lb person walking briskly for 45 minutes burns about 309 Calories, of which about 244 are above what they'd burn sitting still.

What is a MET?

A metabolic equivalent of task (MET) compares an activity's energy cost with sitting quietly, which is 1 MET. Brisk walking at 4.8 METs uses 4.8 times as much energy as rest. The Compendium of Physical Activities lists measured or estimated MET values for over 1,000 activities.

How accurate is a calories burned calculator?

It gives a fair estimate for an average adult, not an exact figure. Real burn varies with fitness, body composition, terrain, wind and technique, and MET values were measured in groups of people. Treat the result as a guide, and compare like with like.

Should I count total or above-resting Calories?

If you're tracking food and exercise together, the Calories above resting are the extra you burned because you exercised, since your body would burn about 1 MET anyway. The total includes that resting share. This calculator shows both.
