Weight Watchers Points Calculator

Quick answer

The Weight Watchers points calculator estimates the points value of a food from its calories, saturated fat, sugar and protein, using the publicly described SmartPoints-style formula, and adds up a daily total.

Points per serving (unrounded)

Points for your servings
9

Points systems turn several nutrition numbers into one, rewarding protein and penalising saturated fat and sugar. The official WW formulas are proprietary and change over time, so this calculator gives an independent estimate that is close to the 2015–2021 SmartPoints values. It is not affiliated with WW.

How to use the Weight Watchers Points Calculator

  1. Calories
  2. Saturated fat
  3. Sugar
  4. Protein
  5. Servings

Results update as you type, and every field accepts the units shown in its menu.

How it works

Read the nutrition label for one serving, enter the four numbers and how many servings you eat. Many foods such as fruit, vegetables, eggs and skinless chicken are zero points in recent WW plans.

Inputs explained

Field What to enter
Calories In kcal
Saturated fat In g
Sugar In g
Protein In g
Servings A number

What each result means

  • Points per serving (unrounded) = max([Calories]×0.0305 + [Saturated fat]×0.275 + [Sugar]×0.12 – [Protein]×0.098, 0)
  • Points per serving = round([Points per serving (unrounded)])
  • Points for your servings = round([Points per serving (unrounded)]×[Servings])

Example values

How the main result changes when Calories changes and everything else stays at the example values above:

Calories (kcal) Points per serving
125 5
187.5 7
250 9
312.5 11
375 13
500 17

Formula

Points ≈ calories × 0.0305 + saturated fat (g) × 0.275 + sugar (g) × 0.12 − protein (g) × 0.098

Worked example

Inputs — Calories: 250 kcal; Saturated fat: 4 g; Sugar: 10 g; Protein: 8 g; Servings: 1.
Results — Points per serving (unrounded) = 9.14; Points per serving = 9; Points for your servings = 9.

Key terms

SmartPoints
The WW points system used from 2015 to 2021.

Frequently asked questions

Is this the official WW formula?

No – WW's current formula is proprietary; this is an estimate based on the published SmartPoints approach.

Why does protein lower the points?

Protein is filling and helps preserve muscle, so it is rewarded.

How many points do I get per day?

It depends on your age, sex, weight and plan; WW sets this individually.
