Scallops are a lean, protein-rich seafood that fits neatly into low-calorie, high-protein meal plans. This scallop calorie calculator estimates how many calories and grams of protein, fat, and carbohydrates you get from any portion, whether you are counting whole scallops, weighing them in grams, or measuring by ounces. You can also select a preparation method, because a plain steamed scallop and a butter-basted restaurant scallop are very different nutritionally.
The calculator uses standard USDA nutrition values for raw mixed-species scallops, then adjusts for common cooking methods such as pan-searing, breading and frying, or baking with garlic butter. It is designed for home cooks, meal preppers, and anyone tracking calories or macros who wants a fast, reliable estimate before dinner hits the plate.

🦪 Scallop Calorie Calculator
Estimate calories and macros for scallops by amount, size, and cooking method.
Quick Start: Using the Scallop Calorie Calculator
Enter the amount of scallops in the number field, choose the matching unit, and pick the preparation method. Press Calculate Calories to see total calories, protein, fat, and carbohydrate, plus a short step-by-step breakdown of the math.
- Whole scallops: choose Large, Medium, or Bay scallops. The calculator applies a typical raw weight of 30 g, 20 g, or 10 g per piece.
- Weight: choose Grams or Ounces when you have a kitchen-scale reading from a fresh package.
- Method: select the option closest to how you cook them. If you use a nonstick pan with no oil, the raw/steamed option is a better match.
The quick-fill buttons (4 large, 100 g, 6 oz, 12 bay scallops) are handy shortcuts for common serving sizes.
How Scallop Calories Are Calculated
The baseline nutrition values come from USDA FoodData Central for raw scallops (mixed species): about 88 calories, 16.8 g protein, 0.8 g fat, and 2.4 g carbohydrate per 100 g. The calculator first converts the amount to grams, then multiplies those per-100 g values by the conversion factor. For example, 50 g of raw scallops provides 0.5 × 88 = 44 calories.
Cooking method changes the numbers because added fat and breading contribute energy. The calculator uses these general benchmarks for a 100 g cooked portion:
- Raw / steamed / poached: ~88 kcal
- Pan-seared with butter or oil: ~140 kcal
- Breaded and fried: ~200 kcal
- Baked in garlic butter: ~180 kcal
These are recipe-based estimates, not lab-tested values for every dish. A tablespoon of butter adds roughly 100 kcal and 11 g fat; preparation often matters more than portion size.
Nutritional Profile of Scallops (Per 100 g Raw)
| Nutrient | Amount per 100 g | Notes |
|---|---|---|
| Calories | 88 kcal | Very low for a protein food |
| Protein | 16.8 g | High-quality complete protein |
| Total fat | 0.8 g | Negligible saturated fat |
| Carbohydrate | 2.4 g | Mostly natural glycogen |
| Sodium | 161 mg | Mild naturally; sauces add more |
| Potassium | 205 mg | Supports blood pressure regulation |
| Vitamin B12 | 2.3 µg | About 96% of the daily value |
| Selenium | 15.6 µg | Antioxidant mineral |
Values are rounded from USDA reference data; actual scallops vary by species, season, and water content.
Worked Examples: From Serving Size to Nutrition
Example 1 — 6 large sea scallops, raw or steamed. Six large scallops ≈ 6 × 30 g = 180 g. Calories = 180 / 100 × 88 ≈ 158 kcal. Protein = 180 / 100 × 16.8 ≈ 30 g. Fat = 1.4 g. That is a generous appetizer for under 160 calories before any oil or butter.
Example 2 — 8 oz breaded and fried scallops. 8 oz × 28.35 = 226.8 g. Using the fried benchmark of 200 kcal per 100 g: 2.268 × 200 = 454 kcal, with about 34 g protein and 25 g fat. The same scallops more than double in calories once breading and frying oil are added.
Tips for More Accurate Scallop Tracking
- Weigh in grams for the most precise result; scallop sizes vary widely even within the same bag.
- If you cook with butter or oil, log the cooking fat separately — it can add 40 to 120 kcal per tablespoon.
- Be aware of 'wet' vs 'dry' scallops. Wet scallops are treated to retain water and shrink more during cooking.
- Restaurant scallops are rarely naked: pan-searing usually includes butter, and a cream or wine sauce can add a few hundred calories.
Pro tip: Buy dry-packed scallops for better browning and less water weight. Their packaged weight better reflects the actual meat you eat.
Watch out: Shellfish allergy is common. If you are allergic to mollusks, avoid scallops entirely even though the calorie math looks attractive.
Frequently Asked Questions
Are scallops good for weight loss? Yes, in moderation. They offer protein and a low calorie count, which supports satiety, but the preparation method is decisive. Broth-steamed scallops and deep-fried scallops from the same restaurant are very different meals.
How many calories are in one scallop? A raw large sea scallop (30 g) contains about 26 calories. A medium scallop (20 g) has about 18 calories, and a bay scallop (10 g) has about 9 calories. Pan-searing with butter roughly doubles the number because of the added fat.
Why do scallops contain carbohydrates? Scallops naturally store glycogen in their muscles, which accounts for about 2.4 g of carbohydrate per 100 g raw. This is not a starchy food; the carb load per serving is very small.
How do scallops compare with other seafood? Scallops are lower in calories than most salmon cuts but also lower in omega-3 fats. For lean-protein comparisons, use the shrimp cholesterol calculator or the salmon net carbs calculator to see how your favorite seafood fits your daily targets.
Can I eat scallops raw? Raw scallops are served as sashimi or crudo, but only if they are truly fresh and sourced from a reliable fishmonger. Freezing does not eliminate all risk. Anyone pregnant, elderly, or immunocompromised should eat scallops fully cooked.
