Standing Desk Calorie Burn Calculator
Build a workday from seated work, standing work, and walking to estimate gross calories and the difference from sitting for the same time. The calculator also estimates how much more selected walking would need to replace sitting to meet a daily target.

Uses 2024 Adult Compendium MET values and the gross convention of 1 MET = 1 kcal/kg/hour.
Additional walking replaces only the calculated remaining sitting time.
How to use this calculator
- Enter body weight and choose pounds or kilograms.
- Set the part of the day that is divided among sitting, standing, and walking.
- Choose the work and walking styles that most closely fit your actual day.
- Enter workdays and working weeks to project the daily difference.
- Set an extra-calorie target to see whether remaining sitting time can be replaced with walking to reach it.
How standing-desk calories are calculated
This calculator treats a workday as three mutually exclusive parts: sitting, standing, and walking. It uses selected 2024 Adult Compendium of Physical Activities MET values. A MET is used here as 1 kcal per kilogram per hour, so the result is a gross energy estimate that includes resting energy expenditure.
First, pounds are converted to kilograms when needed. Remaining sitting time is R = D − S − L, where D is workday minutes, S is standing minutes, and L is walking minutes. Gross workday calories are:
C = (W ÷ 60) × (Ms × R + Mt × S + Mw × L)
- W is body weight in kilograms.
- Ms, Mt, and Mw are the selected sitting, standing, and walking MET values.
The all-sitting comparison uses the same workday and selected sitting MET: B = (W ÷ 60) × Ms × D. The headline is C − B, not the total calories for the day. Weekly and working-year results multiply that difference by the workdays and working weeks entered.
How the walking target works
For a target T, the calculator assumes each additional walking minute replaces one remaining sitting minute. It solves X = max(0, (T − E) ÷ ((W ÷ 60) × (Mw − Ms))), where E is the current extra daily calories. A target is not reachable when the selected walking MET is no higher than the sitting MET, or when the required replacement minutes exceed the remaining sitting time.
What changes the estimate most
Body weight, walking time, and the difference between walking and seated MET values have the strongest direct effects. Standing is not automatically higher than sitting: the Compendium lists both computer work while seated and typing at a standing workstation at 1.3 MET. Fidgeting or light tasks can change the selected value, but the categories are still broad averages.
What this calculator leaves out
MET values do not measure an individual metabolism. The estimate does not account for leaning, workstation design, movement that happens while standing, body composition, disability, or changes in pace and grade. It also does not predict weight loss: food intake, compensation outside work, and many other factors affect body weight over time.
Worked example
For a 180 lb person, the calculator converts weight to 81.65 kg. Suppose an eight-hour workday includes 120 minutes at a 1.3-MET standing workstation, 20 minutes of 3.5-MET walking breaks, and 340 minutes of 1.3-MET computer work. Gross workday energy is (81.65 ÷ 60) × (1.3 × 340 + 1.3 × 120 + 3.5 × 20) = 909.00 kcal.
All 480 minutes at 1.3 MET would be 849.12 kcal, so the mixed schedule is 59.87 kcal higher. Across five workdays and 48 working weeks, that is 299.37 kcal per week and 14,369.81 kcal per working year. A 100 kcal daily target needs another 13.40 minutes of the selected walking to replace sitting, which fits within the 340 remaining sitting minutes.
Common questions
Does standing at a desk actually burn more calories than sitting?
It depends on what changes besides posture. The 2024 Adult Compendium lists seated computer work and a standing computer workstation at the same 1.3 MET value, so that direct substitution produces no estimated difference here. Standing with fidgeting or light tasks can have a higher listed MET value than a quiet seated task.
Why do some standing-desk calculators show much larger calorie differences?
Calculators can use different activity values, duration assumptions, or net-versus-gross conventions. This tool uses selected 2024 Compendium MET values and compares the entered schedule with the same time spent in the selected seated activity. It does not assume that standing itself is vigorous movement.
Do these calories include resting metabolism?
Yes. The calculation is gross because the MET convention used is 1 kcal per kilogram per hour, including resting energy expenditure. Do not add this gross work-period total to another food-tracker estimate that already includes the same period.
How are treadmill-desk and walking-break calories calculated?
Each selected walking style has a Compendium MET value, and the calculator multiplies it by body weight in kilograms and time in hours. It then compares those walking minutes with the seated minutes they replaced. Faster walking, incline, carrying loads, and handrail use can make an actual treadmill-desk session differ from this estimate.
Can standing-desk calories predict weight loss?
No. The yearly value is an energy projection for the entered work pattern, not a weight-loss forecast. Eating, non-work activity, body mass changes, sleep, medication, and metabolic adaptation can all affect long-term body weight.
How much walking should replace sitting to reach a calorie target?
The calculator divides the remaining target by the added calories per minute from selected walking instead of sitting. It marks the target unreachable when the walking style is not more intense than the seated style or when there are not enough sitting minutes left in the entered workday. The result is a planning estimate, not a prescription for a daily activity amount.
