What is the Weight Watchers Points Plus Points Calculator?
The weight watchers points plus points calculator is a specialized tool designed to determine the point value of food items based on the "PointsPlus" system introduced by Weight Watchers (now WW) around 2010. Unlike the original points system, which primarily focused on calories and fat, the PointsPlus method revolutionized the program by considering how different macronutrients—protein, carbohydrates, fat, and fiber—are processed by the body.
Using a weight watchers points plus points calculator helps dieters make more informed decisions. It penalizes foods high in fat and carbohydrates while rewarding foods high in protein and fiber, as the body expends more energy digesting protein and fiber provides satiety. This calculator is ideal for individuals still following the legacy PointsPlus program who need an accurate way to track their daily intake without relying on official app subscriptions that have since moved on to newer systems like SmartPoints.
A common misconception is that this calculator counts calories directly. While calories are part of the equation implicitly, the weight watchers points plus points calculator uses a distinct proprietary formula that converts grams of macronutrients into a single, easy-to-track number.
Weight Watchers Points Plus Points Calculator Formula
The math behind the weight watchers points plus points calculator is more complex than simple addition. It acknowledges the "cost of digestion" (thermic effect of food). The formula balances the energy density of fats and carbs against the satiety and energy expenditure of protein and fiber.
The approximate formula used in our weight watchers points plus points calculator is derived as follows:
PointsPlus = (Protein / 10.9375) + (Carbs / 9.2105) + (Fat / 3.8889) – (Fiber / 12.5)
The final result is usually rounded to the nearest whole integer. Note that while earlier systems capped fiber, the PointsPlus calculation generally allows fiber to subtract from the total score based on the amount present.

Practical Examples
To understand how the weight watchers points plus points calculator works in real-life scenarios, let's look at two distinct food items.
Example 1: Grilled Chicken Breast
Consider a 3oz serving of boneless, skinless grilled chicken breast.
- Protein: 26g
- Carbs: 0g
- Fat: 3g
- Fiber: 0g
Calculation:
(26 / 10.9375) + (0 / 9.2105) + (3 / 3.8889) – (0 / 12.5)
= 2.38 + 0 + 0.77 – 0
= 3.15
Result: The weight watchers points plus points calculator rounds this to roughly 3 Points.
Example 2: Chocolate Chip Cookie
Consider a standard medium-sized chocolate chip cookie.
- Protein: 2g
- Carbs: 20g
- Fat: 9g
- Fiber: 1g
Calculation:
(2 / 10.9375) + (20 / 9.2105) + (9 / 3.8889) – (1 / 12.5)
= 0.18 + 2.17 + 2.31 – 0.08
= 4.58
Result: The weight watchers points plus points calculator rounds this to approximately 5 Points. This shows how high fat and carbs drastically increase the point value compared to protein-heavy foods.
How to Use This Weight Watchers Points Plus Points Calculator
Follow these simple steps to get the most out of this tool:
- Gather Nutritional Info: Locate the Nutrition Facts label on your food packaging. You will need the values for Protein, Total Carbohydrates, Total Fat, and Dietary Fiber.
- Enter Data: Input the exact grams into the corresponding fields in the weight watchers points plus points calculator above. Ensure you are using the values for a single serving size.
- Review Results: The calculator updates instantly. The large blue number is your PointsPlus value.
- Analyze the Breakdown: Check the "Points Breakdown Analysis" chart. It visually demonstrates which macronutrient is driving up the points. If the "Fat" bar is high, consider a lower-fat alternative to save points.
- Copy for Tracking: Use the "Copy Results" button to save the data to your clipboard for your personal food log or spreadsheet.
Key Factors That Affect Weight Watchers Points Plus Results
When using a weight watchers points plus points calculator, several nutritional factors influence the final output significantly.
- Fat Content: Fat is the most "expensive" macronutrient in the PointsPlus system. Because fat contains 9 calories per gram (compared to 4 for protein/carbs), the formula divides fat grams by a much smaller number (~3.9), causing the point value to skyrocket quickly.
- Fiber Savings: Fiber acts as a credit. The weight watchers points plus points calculator subtracts points based on fiber content. High-fiber foods like vegetables and legumes effectively lower the "cost" of the meal.
- Protein Satiety: Protein is treated favorably. The divisor for protein is ~10.9, meaning you can eat significant amounts of protein without accumulating points as quickly as you would with carbs or fats.
- Carbohydrate Density: Simple sugars and complex carbs are treated similarly in the basic math, divided by ~9.2. However, processed foods with high carbs and low fiber will always score higher on the weight watchers points plus points calculator.
- Serving Size: A common error is entering data for the whole package instead of a serving. Always verify the serving size (e.g., "1/2 cup" or "15 chips") to ensure the calculation reflects what you actually eat.
- Rounding Methods: The official system rounds the final result. Our calculator follows standard mathematical rounding to provide the closest integer value, which is crucial for daily point tracking.
Frequently Asked Questions (FAQ)
Does this calculator work for the new SmartPoints system?
No. This weight watchers points plus points calculator is specifically for the "PointsPlus" system used around 2010-2015. SmartPoints uses a completely different formula involving sugar and saturated fat.
Can I calculate points for fruits and vegetables?
In the PointsPlus system, most fresh fruits and vegetables are considered zero points. However, if you are blending them (smoothies) or using dried fruits, you should input their nutritional data into the weight watchers points plus points calculator as they may count towards your daily total.
Why does fiber reduce the point count?
Fiber is not digested by the body in the same way as other carbs. It provides bulk and satiety without adding caloric load. The formula subtracts fiber to encourage the consumption of whole, unprocessed foods.
What is the maximum amount of fiber I can enter?
Technically, you enter the exact amount on the label. While older systems capped fiber at 4g, the PointsPlus logic typically accounts for total fiber, though extremely high amounts are rare in natural servings.
Is alcohol calculated differently?
Alcohol has 7 calories per gram and is not a standard macronutrient in this formula. For pure alcohol calculations, a different variation of the weight watchers points plus points calculator might be needed, often approximated by total calories.
How accurate is this calculator?
This tool uses the reverse-engineered mathematical constants widely accepted by the community for the PointsPlus program. It is highly accurate for personal tracking purposes.
Why did Weight Watchers change from PointsPlus?
WW evolves its science periodically. While PointsPlus was a massive improvement over the original system, newer systems place even heavier penalties on sugar and saturated fats. However, many people still prefer and successfully use the PointsPlus method.
Can I use this for packaged meals?
Yes. Simply read the nutritional label on the back of the box and plug the four key values into the weight watchers points plus points calculator.
