CALCULATE YOUR CALORIES
Looking to figure out exactly how many calories you should eat each day? This free calorie calculator (TDEE calculator) will estimate how many calories you burn daily and how much you should eat to lose weight, maintain, or build muscle. Choose between popular formulas like Mifflin–St Jeor, Harris–Benedict, Katch–McArdle, and Cunningham, adjust for your activity level, and get personalized daily calorie targets plus weekly change estimates. Use it as a starting point, then fine-tune based on your real progress.
Mifflin–St Jeor is a reliable modern default for most people. Harris–Benedict is the classic alternative. If you know your body fat %, Katch–McArdle or Cunningham can personalize estimates using lean body mass.
