How to Use the Weight Watchers Calculator

The Weight Watchers calculator is an invaluable tool to quickly convert the calorie content, saturated fat content, and fiber content to a weight watchers points score.

The Weight Watchers program is designed around the concept of using a points system to rate different foods for nutritional value. That helps you to choose the healthiest foods that will keep you within sensible calorie input limits and avoid the consumption of empty calories.


A typical day’s allowance for someone can be between 18 and 37 WW points, depending on age and current weight.

In order to keep within your daily points allowance you need to assess the foods you are eating for their points value and keep a tally. The Weight Watchers calculator is an invaluable tool for this as it will quickly convert the given calories, saturated fat, and fiber into a points score.

The nutritional values to input are usually found on the label of the food product. They can be expressed in terms of per 100 grams, or per serving (say 25 grams). You enter the values into your calculator and get the points value for that amount of that particular food.

Let’s take an example here of a serving of Twiglets (wheat-based snack food). The energy value is given as 383 kcal, saturated fat 1.3 g, and fiber 3.0 g. If there is no figure specifically for saturated fat, then take the number for fat and halve it. Entering our figures into the calculator we get a Weight Watchers points value of 1.

By the way, many low fat recipes on this website already have the weight watchers points calculated for you.


If you are cooking fresh ingredients at home or eating out in a restaurant you will not know precisely the nutritional values of the foods you are eating. Many fast food restaurants now have websites which give you the nutritional values of their foods.

A medium McDonald burger would register about 8 points for example. (This means with 3 burgers you have used up all your points for that day !)

For nutritional values of fresh cooked foods you will need to consult a database to get an idea. Weight Watchers publish their own guide, the Food Companion Book.


An electronic points calculator is easy to take with you when you go shopping, and enables you to quickly assess the points value of food products before you buy. This means you can plan your meals in advance to ensure that you are well within your daily guidelines.

Better this than get home from your shopping and find out you cannot eat what you had thought as it would take you over your daily limit.. :-( Some electronic Weight Watchers calculators also have the facility to keep track of your points usage for up to seven days.

As you progress with the Weight Watchers program of weight loss you will no doubt get a feel for the points system and how it relates to nutritional value of food. The lower the saturated fat content and higher the fiber, the lower the points value will be for a food, and hence the healthier it is.

A quick reference to the published guide of points values for foods is almost as easy as the use of a calculator, and is more comprehensive in terms of the sheer number of items included.

Who would have thought that half a 300g carton of New Covent Garden Food Co. Leek and Potato soup is 3,5 points while the equivalent amount of Best Chicken soup is 8,5 points?

These lists make fascinating reading for when you have the time. For everyday convenient use however you cannot beat the quick and easy Weight Watchers point calculator. It’s an essential piece of kit in your progress towards weight loss.
