Hi there! My name is Rob & welcome to TDEECalculator.net! My cousin Jake and I co-own this website together. We both became interested in fitness from a relatively young age, and when I began to learn programming as a hobby, Jake convinced me to build this site because he thought it would be a fun project!
It might not seem like it, but TDEECalculator.net has thousands of lines of code powering it and it's quite popular! Jake likes design and I do all the coding as well as make sure the site is fast. If it's running slow or you have any suggestions, please contact us.
TDEECalculator.net currently gets about 100,000 visitors per month (and growing rapidly!) from other sites who link to us, from people who share it on Facebook, & from the search engines. If you find it useful we hope you will share it too!
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
Optionally, if you fill out the body fat percentage field, the calculator will instead use the Katch-McArdle Formula, which is the most accurate formula of all. If you don't know your body fat %, you can pick up a pair of cheap body fat calipers on Amazon, or find a place (try University health departments) that offers DEXA scans. DEXA scans are the gold-standard in determining your body fat percentage and generally cost between $50 - $100.
Katch = 370 + (21.6 * LBM)
where LBM is lean body mass
The revised Harris-Benedict equation has been in use since 1984, and we calculate this as well for those who want it.
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
