TDEE

Estimating your Total Daily Energy Expenditure is as simple as calculating your BMR and multiplying it by your TDEE activity level multiplier.

Approximate TDEE Multiplier	Activity Level
1.2	points for a person who does little to no exercise
1.375	points for a slightly active person who does light exercise 1–3 days a week
1.55	points for a moderately active person who performs moderate exercise 3–5 days a week
1.725	points for a very active person who exercises hard 6–7 days a week
1.9	points for an extra active person who either has a physically demanding job or has a particularly challenging exercise routine

Assuming you have a BMR of 1750 and your activity level is a TDEE value of 1.2 your approximate daily caloric burn is…

$$\begin{array}{rl}\text{TDEE}& =\text{BMR}\ast \text{TDEE Multiplier}\\ \text{TDEE}& =1750\ast 1.2\\ \text{TDEE}& =2100\end{array}$$
