Enter the calories per serving and the number of servings into the calculator to determine the total calories. This calculator can also evaluate any of the variables given the others are known.
Portion Size Formula
The following formula is used to calculate the total calories in a portion size.
TC = CPS * S
Variables:
- TC is the total calories
- CPS is the calories per serving
- S is the number of servings
To calculate the total calories in a portion size, multiply the calories per serving by the number of servings.
What is Portion Size?

How to Calculate Total Calories in a Portion Size?
The following steps outline how to calculate the total calories in a portion size.
- First, determine the calories per serving (CPS).
- Next, determine the number of servings (S).
- Next, gather the formula from above = TC = CPS * S.
- Finally, calculate the total calories (TC).
- After inserting the variables and calculating the result, check your answer with the calculator above.
