What this calculator measures
Daily step count is one of the most underrated levers for managing energy balance. NEAT (Non-Exercise Activity Thermogenesis) — the energy burned through all non-gym movement including walking, fidgeting, and daily tasks — can differ by 500–1,000+ kcal/day between individuals and is often the primary reason TDEE estimates miss for very sedentary people.
How this calculator works
Distance is estimated from step count and height-derived average stride length. Calorie output is estimated as a range because walking speed, terrain, and gait efficiency all affect real expenditure. The estimate uses a scaled MET approach consistent with general walking energy costs from the 2024 Compendium of Physical Activities.
How to use your result
Use daily step count as a practical NEAT proxy. Increasing from 5,000 to 10,000 steps/day can add 200–400 kcal of expenditure without formal exercise. If weight loss has stalled despite consistent calorie intake, check whether your NEAT has declined — a common and overlooked cause of progress plateaus during diets.
