Sedentary TDEE Calculator

Sedentary is the lowest rung on the activity ladder, and it carries the smallest multiplier: 1.2. That number is applied to your Basal Metabolic Rate — the calories your body would burn lying still all day — to estimate what you actually spend across a typical week. A sedentary day is one organised around sitting. You commute by car or train, work at a desk, eat lunch at that desk, and spend the evening on a sofa; the movement that does happen is incidental rather than deliberate, the few hundred steps between rooms and the walk to the kettle. Because so little is layered on top of the resting figure, your Total Daily Energy Expenditure on this setting sits only modestly above your BMR — roughly a fifth higher, no more. That is exactly why the sedentary tier is the honest default for most office workers: it does not pretend that a day of sitting burns like a day on your feet. If your real week genuinely involves more standing, walking or training, a higher tier will describe it better, but the sedentary factor is where you start when the bulk of your waking hours are spent seated. The figure it returns is a calm baseline to plan around, not a verdict on how active you ought to be.

The reason two people with the same desk job can land on different daily burns is something called NEAT — non-exercise activity thermogenesis. It is the energy spent on everything that is not formal exercise and not sleeping: fidgeting, shifting in your chair, standing to take a call, pacing the kitchen, carrying groceries, taking the stairs. For someone who never trains, NEAT is often the largest swing factor in the whole day, and prolonged sitting is precisely what collapses it. Hour after hour in a chair flattens those incidental movements toward zero, which is why a sedentary week sits so close to the bare resting figure. The encouraging side of the same fact is that NEAT is the lever a desk-bound person can actually move without setting foot in a gym: a standing desk for part of the morning, a short walk on every call, a habit of getting up each hour, and a deliberate daily step count all nudge the burn upward. If you would rather see how those steps translate into calories, the Steps to Weight Loss Calculator puts a number on them. And for the full activity ladder with every tier laid out side by side, the TDEE Calculator is the parent tool this page is built from.

There is a tempting instinct to pick the next activity tier up ‘to be safe’, as though a higher multiplier leaves you a margin for error. In practice it does the opposite. The activity factor is meant to mirror your real week, so selecting ‘lightly active’ when you genuinely sit all day does not buy you safety — it inflates your maintenance estimate by a few hundred calories that you never actually burn. The trouble surfaces later: if you then eat to that inflated number, the deficit you believed you had quietly erases itself, and the scale refuses to budge while you wonder why. Overstating activity is one of the most common reasons a calorie plan stalls. The disciplined approach runs the other way. Start on the sedentary tier, treat the figure as a baseline, hold to it for two weeks, and let the scale tell you the truth — then adjust your intake rather than reaching for a higher activity setting to paper over the gap. The multiplier reflects your life; the intake is the dial you turn. When you are ready to convert this maintenance number into a fat-loss target, the Calorie Deficit Calculator does that step. These figures are general estimates for healthy adults, not medical advice.
