Estimate calories and kilojoules burned during a standing shift — retail, bartending, factory floor, warehouse or any other job that keeps you on your feet — based on your body weight, task intensity and shift length. Standing jobs are physically demanding in a way that's easy to underestimate: a full shift on your feet adds up to meaningful energy expenditure over the course of a day, even before you count the walking, lifting or carrying that often comes with it. This calculator uses verified MET (Metabolic Equivalent of Task) values from the 2024 Adult Compendium of Physical Activities to give you a realistic estimate.
Calorie burn from a standing job depends on how physically demanding the work is, captured here as three tiers: light standing — retail, bartending, filing (MET 1.8), moderate standing — stocking shelves, packing boxes, light assembly/repair work (MET 3.3), and heavy standing — lifting 50+ lbs repeatedly, masonry, painting, paper hanging (MET 4.5). The formula is calories = MET × body weight (kg) × duration (hours). A 75 kg person working an 8-hour shift burns approximately 1,080 kcal (4,519 kJ) at light standing effort, 1,980 kcal (8,284 kJ) at moderate standing effort, and 2,700 kcal (11,297 kJ) at heavy standing effort — well over double the light-tier figure once the job involves genuine lifting or manual handling.
| Job Intensity | MET | Calories | Kilojoules |

The calculation uses a MET (Metabolic Equivalent of Task) value for your job's intensity, your body weight, and the length of your shift. This calculator uses three MET tiers taken directly from the Occupation codes in the 2024 Adult Compendium of Physical Activities — light standing (code 11600, "standing tasks, light effort, e.g., bartending, store clerk, assembling, filing, duplicating, librarian, standing and talking at work", MET 1.8), moderate standing (code 11610, "standing, light/moderate effort, e.g., assemble/repair heavy parts, welding, stocking parts, auto repair, packing boxes", MET 3.3), and heavy standing (code 11630, "standing, moderate/heavy tasks, e.g., lifting more than 50 lbs, masonry, painting, paper hanging", MET 4.5). None of these three codes are flagged as estimated in the Compendium — all three are literature-supported entries.
| Job Intensity | MET | Calories (75 kg, 8-hour shift) | Kilojoules |
|---|---|---|---|
| Light standing (retail, bartending, filing) | 1.8 | 1,080 kcal | 4,519 kJ |
| Moderate standing (stocking shelves, packing boxes) | 3.3 | 1,980 kcal | 8,284 kJ |
| Heavy standing (lifting 50+ lbs, masonry, painting) | 4.5 | 2,700 kcal | 11,297 kJ |
Standing jobs cover a wide range of physical demand, which is why this calculator uses three separate tiers rather than a single figure. Light standing covers roles where you're on your feet but not moving heavy loads — bartending, working a retail counter, filing, assembling small parts, or standing and talking with customers or colleagues. Moderate standing steps up to sustained, hands-on physical tasks done at a steady working pace — stocking shelves, packing boxes, assembling or repairing heavier parts, welding, and general auto repair work. Heavy standing is the most demanding tier, covering repeated lifting of loads over 50 lbs (around 23 kg), masonry, painting, and paper hanging — tasks that call on sustained upper-body and whole-body effort well beyond simply being upright, which is why this tier burns noticeably more energy per hour than the other two.
In terms of energy expenditure, yes — standing burns more calories per hour than sitting, simply because holding an upright posture and making small postural adjustments requires more muscular effort than sitting in a chair. Seated desk work typically sits at a meaningfully lower MET value than any of the three standing tiers used here, which start at MET 1.8. That said, the calorie gap from standing alone (without added movement or lifting) is usually modest on a per-hour basis — the bigger differences in this calculator come from how physically demanding the standing job itself is, not simply from standing versus sitting. Standing at work also carries its own physical considerations, including fatigue in the legs and lower back over a long shift, which is worth balancing against any activity benefit.
Retail and hospitality roles — working a till, stocking a shopfront counter, bartending during a shift, or standing at a reception desk — typically sit at the light standing tier (MET 1.8), since the physical demand is mostly postural rather than involving heavy lifting or repeated exertion. Warehouse and light-assembly roles, including stocking shelves, packing boxes and general parts assembly, move up to the moderate tier (MET 3.3). Factory floor and trade work involving repeated heavy lifting, masonry, painting or paper hanging sit at the heavy tier (MET 4.5) — genuinely demanding work that, over an 8-hour shift, burns well over double what a light standing retail shift does for the same body weight.
The table below holds job intensity constant at the moderate tier (MET 3.3) for a full 8-hour shift, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (8-hour shift) | Kilojoules |
|---|---|---|---|
| 55 kg | 3.3 | 1,452 kcal | 6,075 kJ |
| 65 kg | 3.3 | 1,716 kcal | 7,180 kJ |
| 70 kg | 3.3 | 1,848 kcal | 7,732 kJ |
| 75 kg | 3.3 | 1,980 kcal | 8,284 kJ |
| 85 kg | 3.3 | 2,244 kcal | 9,389 kJ |
| 95 kg | 3.3 | 2,508 kcal | 10,493 kJ |
Here body weight is fixed at 75 kg while both shift length and job intensity change, so you can compare how much a longer shift and a harder tier each add to the total.
| Shift Duration | Light (MET 1.8) | Moderate (MET 3.3) | Heavy (MET 4.5) |
|---|---|---|---|
| 4 hours | 540 kcal / 2,259 kJ | 990 kcal / 4,142 kJ | 1,350 kcal / 5,648 kJ |
| 6 hours | 810 kcal / 3,389 kJ | 1,485 kcal / 6,213 kJ | 2,025 kcal / 8,473 kJ |
| 8 hours | 1,080 kcal / 4,519 kJ | 1,980 kcal / 8,284 kJ | 2,700 kcal / 11,297 kJ |
| 10 hours | 1,350 kcal / 5,648 kJ | 2,475 kcal / 10,355 kJ | 3,375 kcal / 14,121 kJ |
| 12 hours | 1,620 kcal / 6,778 kJ | 2,970 kcal / 12,426 kJ | 4,050 kcal / 16,945 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your shift total into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 75 kg person working a light standing shift for 8 hours burns about 1,080 kcal, which is roughly 4,519 kJ — a useful figure to weigh up against the energy value printed on meals or drinks consumed during or after a shift.
How many calories does standing at work burn?
It depends on how physically demanding the job is. A 75 kg person working an 8-hour shift burns around 1,080 kcal at light standing effort — retail, bartending, filing (MET 1.8), around 1,980 kcal at moderate standing effort — stocking shelves, packing boxes (MET 3.3), and around 2,700 kcal at heavy standing effort — repeated lifting, masonry, painting (MET 4.5). Lighter or heavier people, and shorter or longer shifts, will see proportionally lower or higher numbers, so use the calculator above with your own weight and shift length for a personalised estimate.
Is standing at work better than sitting?
In terms of calories burned per hour, yes — standing requires more muscular effort than sitting, so it sits at a higher MET value than typical seated desk work. That said, the calorie difference from standing alone is usually modest; the bigger factor in how many calories a standing job burns is how physically demanding the specific tasks are, not simply whether you're on your feet. Standing all day also brings its own physical considerations, such as leg and lower-back fatigue, which are worth weighing against any activity benefit.
How many calories does a retail worker burn in an 8-hour shift?
Most retail counter and till work — along with bartending, filing and similar front-of-house roles — falls into the light standing tier (MET 1.8), since the physical demand is mostly postural rather than heavy lifting. A 75 kg retail worker on an 8-hour shift burns roughly 1,080 kcal (about 4,519 kJ) at this tier. Roles that also involve regular stocking or box handling will burn more, closer to the moderate standing tier used in this calculator.
Does standing all day help you lose weight?
Standing all day burns more energy than sitting all day, and over a full shift that difference can add up. However, weight loss depends on total energy balance across your whole day — food intake, all other activity, and overall lifestyle — not on standing at work alone. A demanding standing job, especially one involving lifting or moving stock (the moderate or heavy tiers in this calculator), contributes more meaningfully to daily energy expenditure than a light standing role, but neither replaces a broader approach to weight management. This calculator estimates energy expenditure only and isn't personalised weight-loss advice.
How does factory work compare to office work for calories burned?
Factory floor work, particularly heavy tasks like repeated lifting, masonry-style labour or painting, sits at the top of this calculator's range at MET 4.5 — meaningfully higher than seated office desk work, which typically has a lower MET value than even the lightest standing tier used here (MET 1.8). Over a full 8-hour shift, that gap compounds: a 75 kg person doing heavy standing factory work burns roughly 2,700 kcal, compared with a much lower figure for a full day spent mostly seated at a desk.
How is calories burned standing at work calculated?
The calculator multiplies a MET (Metabolic Equivalent of Task) value for your chosen job intensity by your body weight in kilograms and by your shift duration in hours: calories = MET × body weight (kg) × duration (hours). The three MET values used — 1.8 for light standing, 3.3 for moderate standing, and 4.5 for heavy standing — come directly from the Occupation codes in the 2024 Adult Compendium of Physical Activities. The result in kilocalories is then multiplied by 4.184 to give the equivalent figure in kilojoules, the unit used on Australian food labels.
Does body weight affect how many calories you burn standing at work?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At the moderate standing tier for an 8-hour shift, an 85 kg person burns roughly 2,244 kcal compared with about 1,452 kcal for a 55 kg person doing the identical job at the identical intensity for the identical shift length.
Can a standing desk give the same benefit as a standing job?
A standing desk sits closer to this calculator's light standing tier (MET 1.8) than to the moderate or heavy tiers, since it typically involves postural standing without the stocking, packing, lifting or trade-related exertion that pushes a job into those higher tiers. A standing desk can still burn more calories per hour than sitting, but it won't match the energy expenditure of a genuinely physical standing job such as warehouse stocking or manual handling — for that level of burn, the activity itself needs to involve real physical effort, not just an upright posture.
