Total energy expenditure

Calculate your daily calorie consumptionThis is a very precise metabolic calculator. It calculates your resting metabolic rate and your total energy consumption in calories or kilojoules. This can be a helpful tool for weight loss as it allows you to estimate the amount of calories that represents your energy balance.


1. Use the dials until you have entered time spend on sleeping and other activities on a typical day (24 hours).
2. The calculator assumes that all unaccounted time is spend sitting.

Basal metabolic rate
Total energy expenditure
Intense exercise
Moderate exercise
Light exercise
Standing / walking
Maximum effort
Intensity sports
Fast running
Fast rowing
Strength training
Most sports
Brisk walking
Easy walking
(Remaining time)


Estimate energy expenditureIf you want to increase accuracy of your estimation, you should print this sheet and fill it out hour by hour on a typical day. After that - enter values in to the calculator.




The basal metabolic rate is calculated from the Schofield reference formulas used by WHO including age specific formulas for children. Energy cost of activities are based on various references and because children use relative more energy pr. kg body weight than adults, a dynamic correction is used for children depending on body weight.

At the other end of the scale, obese people tend to have their activity dependent energy expenditure overestimated. Accordingly, a correction factor for body mass indexes over 30 is applied.

In summary: this calculator is reliable for children as well as normal weight and obese adults.

Quoting Jaclyn D Hall:
As a person with a BMI over 30,I find this extremely offensive.....implying that I underestimate my activity based on my weight? I learned at four years old how to tell time and have not lost that ability due to my weight. This is body shaming at its worst.

I think you misunderstood. They are not saying the time is underestimated, they are saying the amount burned in that time is underestimated because the formulas used are not accurate at the higher BMI levels

Its like you read my mind! You seem to know a lot
about this, like you wrote the book in it or something.
I think that you could do with a few pics to drive the message home a bit, but instead
of that, this is great blog. An excellent read. I'll definitely be back.

I would like to just say first of all that everyone one of us is struggling right now ludie so don't be rude to Blake

very nice calculator but I cannot tell which formula/model you are using for BMR. Mifflin-St Jeor equation is believed to give the most accurate result for BMR but your tool seems to over estimate by about 100 cals and even high compared to the classic Harris Benedict formula. So you seem to be somewhere around the
Katch-McArdle model ,which is recognised as too high.

I then worry about how you get to the TEE calc, as this will likely be too high.

Can I suggest you at least publish which model formula you are using for this and also consider adjusting to the most accepted accurate ones.

Then this would be a really great tool.

Look fwd to your feedback

Quoting Blake:
I am sorry, but i think this calculator is w bit off. Im 34, 179cm, and 77kg..This thing says i burn 3,655 calories on days when I work out. Is this calculator used for days Im not working out or for my days I am working out? Even on non workout days it says I burn 2,734 calories. Does this mean on my workout days I need to eat more than I burn on that day? Or do I just need to eat more than I burn on a normal day?

Keep in mind that the calories you are given does NOT take into account that you're eating. If you workout as much as you put in and don't eat for the entire day, then yes generally you'll lose around 3,655. However let's say that you're eating about 2,200 calories that day of your workout (which isn't hard to do). That means you only burned 1455.

It can seem a bit high when you get the number but you have to keep in mind all the calories you'll be taking in that cancels out a majority of your tdee.

Am I the only one that thinks this calculator is off? It says that my TDEE is 3800 where many other calcs say that its around 2400-2600. That's quite a large difference IMO.
