Estimate how many calories you burn on a typical day. Enter your age, height, weight, and activity level to see your estimated maintenance calories and how much of that energy you would use at rest.

Choose a typical day
Count movement at work, while commuting, and during exercise. The activity options are example factors within the ranges in the FAO report. A single hard workout may not reflect your usual activity.
Example
At 176 lb, 71 inches, and age 30, the male equation estimates about 1,780 calories a day at rest. With a factor of 1.60, the daily estimate is about 2,849 calories.
How the estimate works
The Mifflin–St Jeor equation estimates resting energy expenditure. Multiplying that number by an activity factor gives a rough estimate of total daily energy use. Both estimates can differ from what you actually burn.
Enter your full height in the selected unit
In the US setting, convert feet and inches to total inches. A height of 5 feet 9 inches is 69 inches. In metric mode, enter centimeters. Use the input labels to check both height and weight after switching units, especially if you are copying measurements from another app.
Compare two activity settings when your routine varies
Keep age, height, and weight fixed and change only the activity setting. For an estimated resting expenditure of about 1,780 calories, factors of 1.45 and 1.60 give about 2,580 and 2,850 calories per day. That difference shows how much the activity assumption affects the estimate.
