How this calculator works and what the numbers mean

This tool helps you explore TDEE using widely published formulas and screening ranges. Results are for learning and self-awareness — they are not a diagnosis and do not replace advice from a qualified clinician.

All math runs in your browser on DoseFirst. Results are rounded for display and meant for learning — not for prescribing, dosing medicines, or making treatment decisions on your own.

Formula used:
TDEE = BMR × activity multiplier
