TDEE Calculator

About This Tool

Look, if you're trying to lose weight, gain muscle, or just stop feeling like you're spinning your wheels with your diet, you need to know your TDEE. That’s Total Daily Energy Expenditure—basically, how many calories your body burns in a day, including everything from breathing to walking to scrolling TikTok on the couch.

This calculator isn’t magic. It won’t tell you exactly what to eat or when to hit the gym. But it will give you a solid starting point. You punch in your age, weight, height, gender, and activity level, and it spits out an estimate of how many calories you burn daily. From there, you can adjust up or down depending on your goals. Want to lose weight? Eat below that number. Want to bulk? Go a little over. Simple.

I built this because I got tired of guessing. Every time I tried a new diet, I’d either starve myself or eat like a linebacker and wonder why I wasn’t seeing results. Turns out, I just didn’t know my baseline. This tool fixes that. No fluff, no nonsense—just math that actually helps.

FAQ

Is this accurate?
It’s an estimate—nothing more. Your actual TDEE can vary based on metabolism, hormones, sleep, stress, and other factors. But it’s way better than guessing. Use it as a starting point, then adjust based on real-world results.

Do I need to recalculate if I lose weight?
Yes. As you lose or gain weight, your calorie needs change. Recalculate every few weeks or after significant progress. Don’t stick to the same number if your body’s changed.
