TDEE & BMI calculator

See your BMI, maintenance calories (TDEE), and separate targets for training days vs rest days — the same formulas Kexo uses in onboarding. Everything runs in your browser.

Educational estimate only — not medical advice. Individual results vary. If you have a medical condition, talk to a clinician before changing how you eat. Daily deficit is capped at 800 kcal and rest-day intake won’t go below 1200 kcal in this calculator, matching Kexo’s safety floors.
