About the Calorie Calculator
Count the calories your body actually needs. This calorie calculator uses the Mifflin-St Jeor equation — the formula dietitians trust most — to estimate your BMR and daily burn (TDEE), then sets a science-based calorie target for losing, maintaining, or gaining weight, complete with a suggested protein, carb, and fat split.
Like every Pixveil tool, this calculator runs 100% in your browser — the numbers you enter are never uploaded, stored, or seen by anyone, and results appear instantly with every keystroke. Use it as often as you like, on any device, free forever, with no account and no ads chasing you around.
Results are estimates for general information only and are not medical advice. Talk to a healthcare professional before making significant changes to your diet or exercise.
