Desk Job TDEE Calculator

Eight hours in a chair is not “lightly active” just because you go to the gym twice. This page defaults to a sedentary-friendly setup and focuses on NEAT — the lever desk workers actually control.

The context

Desk job TDEE is mostly NEAT math

Your job sets a low movement floor. Gym hours matter, but they do not turn a sedentary job into a physically active occupation in the calculator dropdown.

If fat loss stalls, raise steps or tighten tracking before assuming you need a crash deficit.

Why the formula drifts

Office-specific levers

Small daily changes compound.

01

Step target

A fixed floor (e.g. 7k) beats random weekend hero walks.

02

Sitting blocks

Long unbroken sits correlate with lower spontaneous movement later.

03

Desk snacks

Unlogged nibbles are classic office surplus.

04

Lift 2–3×

Protects muscle when calories are controlled.

05

Activity label honesty

Sedentary + gym is common and valid.

06

Screen-late nights

Sleep loss can reduce next-day NEAT.

Method

How this calculator gets to your number

Same Mifflin-St Jeor (or Katch-McArdle) engine as the homepage — with one extra step for this use case.

Run it with my numbers
  1. 1

    Resting burn (BMR)

    Mifflin-St Jeor from age, sex, height and weight. Enter body fat and we switch to Katch-McArdle for leaner or muscular bodies.

  2. 2

    Activity multiplier

    Match the whole week — not your hardest training day. A one-tier mistake usually adds or subtracts 200–400 kcal.

  3. 3

    Desk-day movement

    A small, transparent adjustment for this page’s audience. We keep factors conservative so you can verify with a two-week weight average.
