Weight Watchers Points Calculator

How the Weight Watchers points formula works

This calculator uses the SmartPoints-style equation shown on calculator.net. The formula rewards higher protein and penalizes calories, saturated fat, and sugar. Enter nutrition label values per serving, and the calculator rounds to the nearest whole point.

• Formula: points = calories × 0.0305 + saturated fat × 0.275 + sugar × 0.12 − protein × 0.098.
• Rounding rule: the raw value is rounded to the nearest whole number (0.5 rounds up) and cannot go below zero.
• Units: calories are per serving; saturated fat, sugar, and protein are in grams.

Tips for accurate estimates

• Use the nutrition label values for the exact serving size you plan to eat.
• Double-check sugar and saturated fat grams; they have the biggest impact after calories.
• Pair points with macro and calorie targets to avoid under-eating protein or fiber.

Frequently asked questions

What formula does this calculator use?

We use the SmartPoints-style equation popularized by calculator.net: calories × 0.0305 + saturated fat × 0.275 + sugar × 0.12 − protein × 0.098. The result is rounded to the nearest whole point.

Why is protein subtracted?

Protein increases satiety, so higher-protein foods earn fewer points when calories, sugar, and saturated fat are held constant.

Do I need fiber for this formula?

No. The SmartPoints equation shown on calculator.net does not require fiber. Older Weight Watchers formulas did include fiber adjustments.

How are points rounded?

We round to the nearest whole number using standard rounding rules (0.5 rounds up). Negative values are floored to zero.

Is this the official Weight Watchers tool?

No. This calculator is an estimate based on publicly available formulas and is not affiliated with Weight Watchers.

Can I use points for meal planning?

Yes. Use points as a quick way to compare foods, then pair them with calorie and macro targets for a full nutrition plan.
