How to use it
- 1Choose your sex and unit system, then enter age, height, and weight.
- 2Select your activity level from the dropdown.
- 3Read your TDEE, its resting-vs-activity split and weekly total, and compare calories across every activity level on the chart.
Example
A 1,699 kcal/day BMR becomes roughly 2,633 kcal/day at a moderate activity level (exercising 3-5 days a week) — about 934 kcal/day, or 35% of the total, coming from activity on top of resting metabolism. The chart shows how much that swings across activity levels, and the weekly total shown is that same figure × 7.
How it works
TDEE takes your BMR (calculated with the Mifflin-St Jeor equation) and multiplies it by an activity factor — 1.2 for sedentary up to 1.9 for very active — based on the widely used activity multipliers. It estimates how many calories you burn in a typical day including exercise and daily movement, not just resting. The resting-vs-activity split shows how much of that total comes from simply being alive versus moving around.
