How it is calculated

The estimate uses the net energy cost of moderate walking: kcal per step = weight (kg) × 2 ÷ 6,000 ≈ weight × 0.00033 and NEAT kcal = daily steps × kcal per step. The factor comes from walking at about 100 steps a minute being roughly 3 METs (Tudor-Locke et al., CADENCE-adults, 2019), minus the 1 MET of resting metabolism that NEAT excludes by definition (Levine), with 1 MET taken as 1 kcal per kg per hour (Compendium of Physical Activities): 2 kcal/kg over 6,000 steps. Weight is in kilograms and steps are the number counted in a day. The tool shows the daily energy as a whole number of kcal, the per-step cost with four decimals and the step count. Both inputs must be above zero. Faster or uphill walking costs more per step, and non-walking movement such as fidgeting or standing is not included, so the figure is an estimate of walking NEAT, not a measurement.

Worked example

A person weighing 72 kg takes 8,500 steps a day. The net cost per step is 72 × 2 ÷ 6,000 = 0.0240 kcal. Over the day that is 8,500 × 0.024 = 204 kcal above resting metabolism. Adding 2,000 steps adds 2,000 × 0.024 = 48 kcal. The gross figure including rest would be 8,500 × 72 × 0.0005 = 306 kcal, about 1.5 times as much, because a third of the gross cost of walking is the metabolism the body spends anyway.

Common mistakes

  • Entering body weight in pounds: the field is in kilograms, so 160 lb must be entered as about 72.6 kg, otherwise the result is more than twice too high.
  • Comparing it with a step-calorie figure that includes resting metabolism. Gross figures (0.0005 kcal per kg per step) are about 1.5 times this net NEAT value.
  • Treating the number as total daily calorie burn: it is only the energy of the steps, not your resting metabolism, which is far larger.
  • Counting steps from a workout twice: if the steps came from a deliberate run or gym session, they are exercise, not non-exercise activity.
  • Expecting steps to match another device: wearables count steps differently and may include arm movement, and the tool uses the same cost per step at any pace.

About this calculator

NEAT (Non-Exercise Activity Thermogenesis) is the energy you burn from everyday movement that isn't deliberate exercise — walking to the car, pacing during a phone call, taking the stairs, fidgeting. For most people NEAT accounts for a bigger swing in daily calorie burn than formal workouts do, which is why researchers like James Levine (who coined the term) found it explains much of the variation in weight gain between people eating the same diet.

This calculator estimates the walking part of NEAT from your daily step count and body weight, since walking is the single largest and most trackable component of NEAT for most people. Because NEAT is energy spent above resting metabolism, it counts only the net cost of a step: moderate walking at about 100 steps a minute costs about 3 METs (the CADENCE-adults study), one of which is the resting metabolism you burn anyway, leaving 2 METs, or 2 kcal per kg per hour (1 MET = 1 kcal/kg/h). Spread over the 6,000 steps of that hour this is about 0.00033 kcal per kg per step, so 10,000 steps at 70 kg add about 233 kcal. The gross figure of 0.0005 kcal per kg per step, used by the calorie-burn-from-steps calculator, includes the resting share. It's useful for anyone doing calorie tracking or weight management who wants a more complete picture of energy expenditure than “steps” alone gives them.

    The figure is energy above resting metabolism, so do not add it to a daily estimate that already includes an activity multiplier; the walking would be counted twice. It also covers walking steps only, not fidgeting or standing. Step counters differ in how they count, so use one device for comparing days. Would you rather compare weekdays with weekends or desk days with active days?
