Harris-Benedict Calculator

Classic BMR formula - the traditional approach to calorie calculation

How the Harris-Benedict Formula Works

Originally developed in 1919 and revised in 1984, the Harris-Benedict equation was one of the first formulas to calculate BMR. While slightly less accurate than newer formulas, it remains widely used and provides good estimates for most people.

Men: BMR = 88.362 + (13.397 × weight) + (4.799 × height) - (5.677 × age)
Women: BMR = 447.593 + (9.247 × weight) + (3.098 × height) - (4.330 × age)
