Daily Energy Expenditure from Steps Calculator
Estimate your total daily calorie burn (TDEE) from your step count: resting metabolism (entered or estimated with Mifflin-St Jeor), everyday movement, the net energy of your steps from stride and walking pace, other exercise and digestion — with a breakdown chart, step-count table and calorie targets.
How it works
BMR = entered, or Mifflin-St Jeor: 10 × kg + 6.25 × cm − 5 × age + 5 (men) or − 161 (women) · stride ≈ height × 0.415 (men) or 0.413 (women) · walking time = steps × stride ÷ speed · step calories (net) = (MET − 1) × 3.5 × kg ÷ 200 × minutes · TDEE = (BMR × daily-movement multiplier + step calories + other exercise) ÷ 0.9 with digestion, or without the ÷ 0.9
Your daily burn has four parts: resting metabolism (BMR), everyday movement that is not walking (standing, chores, fidgeting), purposeful activity such as your steps, and digestion. Enter a measured BMR or let the calculator estimate it with the Mifflin-St Jeor equation from sex, age, height and weight. The baseline multiplies BMR by a small factor for non-step movement. Your steps are turned into distance using your stride (about 41% of height, or the length you enter) and into time using your usual walking pace; the MET value for that pace from the 2024 Compendium of Physical Activities then gives the energy. Only the net part — the energy above resting — is added, because the BMR already covers the resting burn during those minutes; that is why the step calories here are lower than a watch’s figure. Digestion (the thermic effect of food) takes about 10% of what you eat, so with it switched on the total is divided by 0.9. You also get distance and walking time, your overall activity factor, a step-based activity level, a table for other step counts, calorie targets and a breakdown chart.
Worked example
A 70 kg, 170 cm man with a BMR of 1,600 kcal and light daily movement (× 1.15) has a 1,840 kcal baseline. His stride is 170 × 0.415 = 70.6 cm, so 8,000 steps cover 5.64 km, about 70 minutes at an average 4.8 km/h. Moderate walking at that pace is 3.8 METs in the 2024 Compendium, so the net walking cost is (3.8 − 1) × 3.5 × 70 ÷ 200 × 70.1 ≈ 241 kcal (a watch would show about 327 kcal gross). With digestion, the total is (1,840 + 241) ÷ 0.9 ≈ 2,312 kcal — about 1.44 × his BMR.

Frequently asked questions
Why are my step calories lower than my watch shows?
Most trackers report gross calories, which include the energy your body would burn at rest anyway during the walk. Because your BMR is already part of the total, this calculator adds only the net walking energy; adding the gross figure would count the resting part twice.
Why scale calories per step by weight?
The energy to move your body is roughly proportional to its mass. A 90 kg person burns noticeably more per step than a 55 kg person walking the same distance, so a flat “one calorie per step” rule overstates burn for lighter people and understates it for heavier ones. Taller people also cover more ground per step.
Is this the same as TDEE?
It estimates total daily energy expenditure specifically for a step-tracked day. A standard TDEE calculator applies one lifestyle multiplier; this one splits out the measured step contribution, other exercise and digestion, so an unusually active or lazy day is captured.
How many steps a day count as active?
A widely used step index (Tudor-Locke) calls under 5,000 steps a day sedentary, 7,500–9,999 somewhat active, 10,000–12,499 active and 12,500 or more highly active. Health benefits rise steeply up to roughly 7,000–8,000 steps a day for most adults.
Does phone step accuracy matter?
Yes — wrist and phone counters can miss slow steps or over-count arm movement. Treat the total as a ballpark and compare trends day to day rather than trusting any single figure.
