How it works
BMR is computed from your stats; TDEE = BMR × activity factor. Enter your data and choose an activity level to see maintenance calories. Reduce for weight loss, increase for gain.
When to use it
Use it to set a daily calorie target or to compare with other calculators. Always combine with a healthcare provider for major diet changes.
