How treadmill calorie burn actually works

The calorie number on a treadmill's console is almost always an overestimate — it rarely accounts for your body weight, and it ignores whether you're holding the handrails. A realistic estimate comes from the ACSM metabolic equations, the same clinical formulas used in exercise physiology labs. They convert your speed, incline, and body weight into oxygen uptake (VO₂), then into calories burned per minute.

Four things drive the result: speed (how fast the belt moves), incline (the single biggest lever — walking uphill can double your burn), body weight (heavier bodies move more mass), and duration. This page brings all four together: use the calculator above for your exact numbers, then explore the tables below for any specific speed, incline, time, or weight.

Each page below shows an ACSM-based breakdown for a specific setup, with a comparison table you can adjust to your own weight and pace.

Calories by speed
