How to Calculate Weight Watchers Points. You can calculate the Weight Watchers point value for food items or meals if you know the formula and know where to look. Follow these steps.
Calculate the Point Value Yourself
Look at the food item's packaging or lable for nutrional values. Divide the calories by 50.
Divide the total fat grams by 12.
Add the values from Steps One and Two to get the value of "X."
Divide the dietary fiber grams by 5 to equal "Y."
Take "X minus Y" to find the point value of the food item. Round up values higher than .5 and round down for values lower than .5.

At the prompt, enter the calories, the fat and the fiber amounts for the food item. Push "Enter" after each entry.
