Gummy serving size calculator

See what a complete labeled serving means for one piece or your own portion. Compare two products using the same units, with exact values from your package or our dated source dataset.

Start with both labels. Fields marked * are required. Enter at least one known nutrient or calorie value for each product. Your entered values stay in your browser. Calculations do not establish ingredient quality or recommend a dose.

PRODUCT A

Start with a dated brand source optional

Use your package label, or choose a dated brand source.

Product name optional

Pieces per labeled serving

Pieces in your portion

Use values from the same full labeled serving. Leave unreported values blank. Enter 0 only if the label says 0. For “less than” values such as <1 g, leave the number blank.

Protein (g) optional

Dietary fiber (g) optional

Total sugars (g) optional

Calories (kcal) optional

PRODUCT B

Start with a dated brand source optional

Use your package label, or choose a dated brand source.

Product name optional

Pieces per labeled serving

Pieces in your portion

Use values from the same full labeled serving. Leave unreported values blank. Enter 0 only if the label says 0. For “less than” values such as <1 g, leave the number blank.

Protein (g) optional

Dietary fiber (g) optional

Total sugars (g) optional

Calories (kcal) optional

Enter the required values for both products to compare their labels.

YOUR LABEL ARITHMETIC

Same units. A clearer comparison.

Values are scaled from the label and rounded for display. This assumes nutrients are evenly distributed across pieces. On a small screen, swipe within each table to see all columns.

Product A

Grams and calories calculated from the entered label
Label value	Full serving	One piece	Your portion
Protein	Not entered	Not entered	Not entered
Dietary fiber	Not entered	Not entered	Not entered
Total sugars	Not entered	Not entered	Not entered
Calories	Not entered	Not entered	Not entered

Compare per 100 calories

A standardized arithmetic view only. It is not a suggested serving and can magnify differences caused by rounded label calories.

Protein per 100 kcal: Not entered
Dietary fiber per 100 kcal: Not entered
Total sugars per 100 kcal: Not entered
Calories per 100 kcal: Not entered

Product B

Grams and calories calculated from the entered label
Label value	Full serving	One piece	Your portion
Protein	Not entered	Not entered	Not entered
Dietary fiber	Not entered	Not entered	Not entered
Total sugars	Not entered	Not entered	Not entered
Calories	Not entered	Not entered	Not entered

Compare per 100 calories

A standardized arithmetic view only. It is not a suggested serving and can magnify differences caused by rounded label calories.

Protein per 100 kcal: Not entered
Dietary fiber per 100 kcal: Not entered
Total sugars per 100 kcal: Not entered
Calories per 100 kcal: Not entered

“Not entered” means unknown or not supplied, never zero. Values shown as <0.01 are smaller than the display precision. Product labels are rounded, so derived values are arithmetic estimates rather than laboratory measurements.

See the serving calculation

A full labeled serving can contain more than one gummy. The example below shows why comparing a serving with a single piece changes the result.

Fictional gummy A: 5 grams fiber divided by 2 gummies equals 2.5 grams per gummy. Fictional gummy B: 6 grams divided by 3 gummies equals 2 grams per gummy. — These fictional values match the worked example below. B has more fiber per complete serving; A has more per gummy. The calculation assumes nutrients are evenly distributed across pieces. It does not recommend a dose. Open the scalable illustration.

How the serving math works

Per piece = labeled amount ÷ pieces per serving
Your portion = per-piece amount × pieces in your portion
Per 100 kcal = labeled amount ÷ labeled calories × 100

Keep every number tied to the same exact product and labeled serving. A pouch, an adult serving, and a child serving can describe different amounts.

The preset menu uses our dated manufacturer-source dataset. The complete study methodology explains inclusion, source types, unknown values, and limitations. Check your current package before relying on a saved preset.

No serving is recommended here. Normalizing to one piece or 100 calories does not make different formulas equivalent. Per-100-calorie results are unavailable when calories are missing or labeled zero.

A worked example

Fictional gummy A lists 5 g fiber in a two-piece serving. Its calculated fiber per piece is 5 ÷ 2 = 2.5 g. One piece represents half of that labeled serving.

Fictional gummy B lists 6 g fiber in a three-piece serving. Its calculated fiber per piece is 6 ÷ 3 = 2 g. B has more fiber per full serving, while A has more per piece in this example.

What a blank label field means

A missing protein figure is not the same as a label reporting 0 g protein. A bound such as “less than 1 g” is not an exact 1 g. Presets leave such values blank instead of turning them into an unsupported number.
