Formulas Used

BestMacroCalculator.net relies on scientifically validated equations to estimate your calorie needs. The primary formula used is the Mifflin-St Jeor equation, which calculates your Basal Metabolic Rate (BMR) and then adjusts it according to your activity level for an accurate TDEE estimation.

Katch-McArdle Equation

If you provide your body fat percentage, the calculator will instead use the Katch-McArdle equation, considered the most precise formula available. If you're unsure of your body fat %, you can purchase inexpensive body fat calipers or seek out a facility—such as university health departments—that offers DEXA scans. These scans, which generally cost between $50 - $100, are the gold standard for measuring body fat percentage.

Katch = 370 + (21.6 * LBM)

where LBM is lean body mass

Mifflin-St Jeor Equation

Mifflin = (10.m + 6.25h - 5.0a) + s

m is mass in kg, h is height in cm, a is age in years, s is +5 for males and -151 for females

Revised Harris-Benedict Equation

The revised Harris-Benedict equation has been widely used since 1984. For those who prefer this method, we also provide its calculation for comparison.

Harris-Benedict = (13.397m + 4.799h - 5.677a) + 88.362 (MEN)
Harris-Benedict = (9.247m + 3.098h - 4.330a) + 447.593 (WOMEN)

m is mass in kg, h is height in cm, a is age in years
