Mozzarella Nutrition Calculator

How to Use This Calculator

Pick the mozzarella variety that best matches what you are eating — whole milk, part-skim, low-moisture part-skim, or fresh mozzarella — then enter your serving amount in whatever unit is most convenient. The tool accepts grams, ounces, cups of shredded cheese, whole fresh balls, and deli slices, and it converts everything to a gram weight before applying the nutrition values. Use the preset buttons for common servings like a 28 g slice or a 100 g portion, or type any custom amount. If you are tracking macros for a specific diet, tick the "Show % Daily Value" box to see how the serving fits into a standard 2,000-calorie daily plan, including calcium and sodium percentages.

How the Numbers Are Calculated

All nutrition values are based on USDA FoodData Central reference entries for each mozzarella variety, expressed per 100 grams. The calculator first converts your serving to grams using fixed weight factors: 1 ounce equals 28.35 g, 1 cup of shredded mozzarella equals about 112 g, one average fresh mozzarella ball equals 125 g, and one deli slice equals about 28 g. It then scales every nutrient linearly: for a 150 g serving, each value from the 100 g baseline is simply multiplied by 1.5. This linear scaling is accurate for whole cheeses because their composition is essentially uniform throughout the block. Calories are rounded to the nearest whole number, while grams are shown to one decimal place for helpful macro tracking.

Worked Examples

Example 1 — Caprese salad. A typical caprese serving uses about 60 g of fresh mozzarella. The calculator gives roughly 156 kcal, 12.2 g protein, 11.7 g fat, and 234 mg calcium, making it a light but satisfying lunch base with tomatoes and basil.

Example 2 — Homemade pizza. Two cups of shredded low-moisture part-skim mozzarella weigh about 224 g. That works out to approximately 672 kcal, 54.4 g protein, 45.7 g fat, and 1,288 mg calcium — the calcium alone covers a full day's requirement for most adults, which is why cheese dominates pizza nutrition.

Example 3 — Snacking slices. Three deli slices of part-skim mozzarella (roughly 84 g total) provide about 235 kcal, 23.1 g protein, and only a modest 3 g of carbohydrate, an easy high-protein snack option.

Common Questions

Why does part-skim mozzarella have more protein than whole milk? Removing part of the cream concentrates the curd, so protein density rises while fat drops — that is why part-skim often fits higher-protein meal plans better than the richer whole-milk version.

Is fresh mozzarella healthier than aged mozzarella? It depends on your goals. Fresh mozzarella has fewer calories and much less sodium, but also less calcium and protein per gram because of its higher water content. If you want maximum calcium, low-moisture part-skim is the strongest choice among these four.

Why do nutrition labels report 28 g while the calculator uses 100 g values? Food labels use the serving size defined by the manufacturer, while nutrient databases standardize per 100 g so all foods can be compared on an equal basis. Both approaches are correct; the calculator simply makes homemade servings easy to convert.
