Treadmill calorie calculator
Written by Jamie Miller, Founder & EditorLast checked
This is a population-average estimate, not a measurement of you. It uses the MET method from the Compendium of Physical Activities, the standard exercise-science reference for converting activity and body weight into an energy estimate. Two people at the same speed and weight can genuinely burn different amounts, because fitness, stride and effort all vary. Treat the number as a reasonable estimate to plan around, not a precise reading.Independently verified, Independent publication, checked 18 Sept 2026

Where the formula comes from, and its real limits
kcal per minute = MET × 3.5 × bodyweight in kg ÷ 200. MET stands for Metabolic Equivalent of Task: one MET is roughly the energy cost of sitting quietly, and an activity's MET value is how many multiples of that it costs. The values above come from the Compendium of Physical Activities, the reference table exercise scientists and the ACSM use for exactly this calculation. It does not account for incline, individual fitness, age, sex or genuine metabolic differences between people, all of which move the true figure in either direction.
Incline matters more than most calculators admit: walking at even a modest incline can raise energy cost substantially above the flat figures here, because you are doing mechanical work against gravity as well as moving forward. We do not have a verified incline-adjustment formula we are confident publishing, so this calculator is flat-belt only.Not established, checked 18 Sept 2026
What we have not measured
We have not measured anyone's actual calorie burn, on a treadmill or otherwise. Everything above is a published formula applied to numbers you provide, not a result from testing. If you want a genuinely individual figure, a heart-rate based fitness tracker or a lab metabolic test will get closer than any calculator, including this one.How we review.
